The 8 Most Asked Questions About Dissertations

A Ph.D. represents the highest level of education in most fields. People who earn this degree earn the honorific of “doctor” and are considered experts in their field. A doctoral degree is often a prerequisite for teaching at the highest levels in academia or ascending career ladders in education, the government and the nonprofit space.

In 2020 , doctoral degree holders had median weekly earnings of $1,885 and an unemployment rate of 2.5%—lower than any other group. And yet, the dissertation is often a major barrier to completing a doctorate and realizing its many financial and personal benefits. 

So what is a dissertation, and what role does it play in your educational trajectory? At SNU, we value exceptional dissertations and integrate the writing process into your coursework. Here are the most common questions we hear about writing dissertations and earning your doctorate.

1. What is a dissertation?

A dissertation is a published piece of academic research. Through your dissertation research , you become an expert in a specific academic niche. After writing your dissertation, you then defend it to a committee of experts in the field. A dissertation is integral to the process of earning a doctoral degree, contributing innovative ideas to your chosen field. Until you have written, published and defended a dissertation, you can’t graduate from a doctoral-level program.

2. Why are dissertations so important?

Dissertations are the crucial piece of research in most doctoral-level programs. The process of writing, researching and amending the dissertation serves several important goals: 

• It contributes novel research to the field, supporting innovation, growth and ongoing scholarship. 
• It requires students to write a substantive piece of academic research across many semesters, sharpening research skills and expertise. 
• It demands that s tudents defend their research, ensuring strong communication and critical thinking skills. 
• It requires deep, comprehensive research—including a literature review—improving reading comprehension and writing skills. 
• It is a challenging project that serves as a test of the skills you might use as an academic professional in your chosen field. 
• It helps establish new members of an academic discipline as contributors to the field. 
• It fosters academic connections as you interview sources and defend your work.

3. Why do so many students struggle with the dissertation?

The dissertation process is difficult. However, this difficulty establishes the credibility of doctoral degrees, proving that the student can commit to long-term, intensive research and become a true subject-matter expert. 

However, for many adult learners, the dissertation proves especially challenging thanks to work-life balance difficulties, financial constraints and lack of family or institutional support. At SNU, we know that a dissertation is critical to your growth as an academic. But we also know that institutional support can make a big difference in your ability to finish this impressive work. That’s why we integrate dissertation writing into our curriculum, rather than leaving you to do it all on your own time. 

One study suggests that more than half of students never complete their dissertation. Other research indicates that academic reforms that help students with their work reduce dropout rates, ensuring more students complete their dissertation and earn the coveted title of doctor.

4. How long is a dissertation?

Most dissertations are 100 pages or longer — roughly the length of a book. The specific length of your dissertation depends on the type of research, how much research exists in the field and similar factors. The goal of dissertation writing is not to attain a specific length, but to be comprehensive and thoughtful. It anticipates and answers potential objections, gives appropriate credit to the source materials and reviews prior work in the field. 

Your dissertation review committee is more interested in a comprehensive dissertation that displays your critical thinking and research skills than they are in a dissertation of a specific length. Excessive wordiness without value wastes a reader’s time.  

The right length for a dissertation depends on several factors: 

• How much research already exists in the field?
• What field are you publishing in?
• What type of research are you doing?
• Is your research controversial?
• How much space do you need to explain your research and address objections?

Put simply: A dissertation should be long enough to comprehensively cover the subject, but no longer.

5. How do you write a dissertation?

In general, the dissertation process follows this schedule: 

• Research the field and identify potential topics. 
• Meet with an advisor to choose and improve a topic. 
• Perform a literature review. 
• Conduct new research. 
• Write the dissertation. 
• Edit the dissertation. 
• Defend the dissertation.

Each step involves weeks to months of work and many phases of revision, reevaluation and research. At SNU, we incorporate many phases of the writing and research process into your coursework. This ensures you are on track to graduate and addresses dissertation writing challenges before they snowball into a serious problem.

6. When should you start writing a dissertation?

The dissertation writing process should begin almost as soon as you enroll in school. That doesn’t necessarily mean you need to have content written on your first day of class. Instead, you will need to engage in substantive pre-writing that includes: 

• Familiarizing yourself with relevant research in the field. 
• Developing an opinion on recent research. 
• Designing your research to address a clear and narrowly defined topic. 

As you hone in on your topic, you can begin the writing and research portion of the project. In most cases, this starts within a semester or two of enrollment. A dissertation is not something you can leave until the last semester or shortly before graduation. SNU ensures this doesn’t happen by integrating the writing process into your coursework. You will start working on your dissertation early, preventing you from becoming overwhelmed.

7. How do you cite a dissertation?

A dissertation is a published scholarly work. Each style manual has specific instructions for citing a dissertation, so be sure to consult the style manual you’re using. 

You can cite other dissertations in your dissertation. In many cases, dissertations can provide useful starting points for your research. The literature reviews they contain may also help with your literature review.

8. How do you choose a school for your dissertation?

Choosing the right school for your dissertation can mean the difference between finishing this scholarly work and languishing at the dreaded “ all-but-dissertation” (ABD) stage . SNU specializes in supporting adult learners by encouraging intensive research and protecting your work-life balance. 

At SNU, your dissertation is a part of your coursework . You will get support from start to finish, including a dissertation advisor who is an expert in your chosen field. We are here for you, and we want to see you succeed.

How long is a Thesis or Dissertation? [the data] PhD, Masters +

Writing a thesis for your undergraduate, master’s, or PhD can be a very daunting task. Especially when you consider how long a thesis can get. However, not all theses are the same length and the expected submission length is dependent on the level of study that you are currently enrolled in and the field in which you are studying.

An undergraduate thesis is likely to be about 20 to 50 pages long. A Master’s thesis is likely to be between 30 and 100 pages in length and a PhD dissertation is likely to be between 50 and 450 pages long.

In the table below I highlight the typical length of an undergraduate, master’s, and PhD.

It is important to note that this is highly dependent on the field of study and the expectations of your university, field, and research group.

If you want to know more about how long a Masters thesis and PhD dissertation is you can check out my other articles:

• How Long is a Masters Thesis? [Your writing guide]
• How long is a PhD dissertation? [Data by field]
• How to write a masters thesis in 2 months [Easy steps to start writing]

These articles go into a lot more detail and specifics of each level of study, including master’s and doctoral degrees.

Let’s take a more detailed look at the length of a thesis or dissertation. We’ll start from the very basics including what a dissertation or thesis really is.

What exactly is a thesis or a dissertation?

A thesis or a dissertation is a research project that is typically required of students in order to gain an advanced degree.

A dissertation is usually much longer and more detailed than a thesis, but they both involve extensive research and provide an in-depth analysis of their given subject.

Many people use the term interchangeably but quite often a Masters level research project results in a thesis. While a PhD research project results in a much longer dissertation.

Thesis work is usually completed over the course of several months and can require multiple drafts and revisions before being accepted. These will be looked over by your supervisor to ensure that you are meeting the expectations and standards of your research field.

PhD Dissertations are typically even more involved, taking years to complete. My PhD took me three years to complete but it is usual for them to take more than five years.

Both a thesis and a dissertation involve researching a particular topic, formulating an argument based on evidence gathered from the research, and presenting the findings in written form for review by peers or faculty members.

My Master’s thesis was reviewed by the chemistry Department whilst my PhD thesis was sent to experts in the field around the world.

Ultimately, these experts provide a commentary on whether or not you have reached the standards required of the University for admittance into the degree and the final decision will be made upon reviewing these comments by your universities graduation committee.

There are several outcomes including:

• accepted without changes – this is where you must make no changes to your thesis and is accepted as is.
• accepted with minor changes this is where your thesis will require some minor changes before being admitted to the degree. Usually, it is not sent back to the reviewers after the thesis defence.
• Major changes – this is where the committee has decided that you need to rework a number of major themes in your thesis and will likely want to see it at a later stage.
• Rejected – this is where the dissertation or thesis is rejected and the recommendation to downgrade your degree program is made.

What is the typical length of a thesis or dissertation?

The length of a thesis or dissertation varies significantly according to the field of study and institution, especially in social sciences.

Generally, an undergraduate thesis is between 20-50 pages long while a PhD dissertation can range from 90-500 pages in length.

However, longer is not necessarily better as a highly mathematical PhD thesis with proofs may only be 50 pages long.

It also depends on the complexity of the topic being studied and the amount of research required to complete it.

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field, including social sciences.  It has been created by Marcus Beck  from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a master’s or doctoral degree in your field. 

How Many Pages Should a Master or PhD Thesis Have? Length of a thesis?

The length of a master’s thesis can vary greatly depending on the subject and format.

Generally, a masters thesis is expected to be around 100 pages long and should include:

• a title page,
• table of contents,
• introduction,
• literature review, 
• main test and body of work, 
• discussions and citations,
• conclusion,
• bibliography
• and (sometimes) appendix.

Your supervisor should provide you with a specific format for your dissertation or thesis that you are expected to follow.

Depending on your field of study and the word count specified by your supervisor, these guidelines may change. The student must ask their advisor for examples of past student thesis and doctoral dissertations. 

For example, if there is a limited number of words allowed in the thesis then it may not be possible to have 100 pages or more for the thesis.

Additionally, if you are including a lot of technical information such as diagrams or tables in the appendix of your dissertation or thesis, then this could increase the page count as well. For example, my PhD thesis contained a page like the one below.

This page only contains images from atomic force microscopy. Because my PhD was very visual, many pages like this exist.

Ultimately it is important to consult with your supervisor and determine how many pages your master’s thesis or PhD dissertation will be expected to have.

How long does it take to write a graduate thesis? Write your thesis quickly

Writing a graduate thesis can be a daunting task.

It is typically expected to take anywhere from one to three years, depending on the subject and scope of the project.

However, this is not just writing. A typical thesis or dissertation will require you to:

• formulate a research question
• do a literature review
• create research methodology
• perform original research
• collect and analyse results
• write peer-reviewed research papers
• write a PhD/masters thesis
• submit thesis and respond to examiners comments.

The actual writing component of a thesis or dissertation can take anywhere from one month to 6 months depending on how focused the PhD student is.

The amount of time it takes to write a thesis or dissertation can vary based on many factors, such as the type of research required, the length of the project, and other commitments that may interfere with progress.

Some students may have difficulty focusing or understanding their topic which can also add to the amount of time it takes to complete the project.

Regardless, writing a thesis is an important part of obtaining a graduate degree and should not be taken lightly.

It requires dedication and determination in order for one to successfully complete a thesis or dissertation within an appropriate timeframe.

In my YouTube video, below, I talk about how to finish your thesis or dissertation quickly:

It is full of a load of secrets including owning your day, managing your supervisor relationship, setting many goals, progress over perfection, and working with your own body clock to maximise productivity.

Wrapping up

This article has been through everything you need to know about the typical length of a dissertation or thesis.

The answer to this question is highly dependent on your field of study and the expectations of your supervisor and university.

Frequently Asked Questions: How Long is a Thesis

How long is a thesis.

A thesis is typically a document submitted in support of an academic degree, presenting the author’s research and findings. The length of a thesis can vary depending on the level of study and specific requirements of the institution. It can range from 60 – 100 pages for a master’s thesis to several hundred pages for a doctoral dissertation.

What is the difference between a thesis and a dissertation?

While the terms thesis and dissertation are often used interchangeably, they can have different meanings depending on the region or academic context. In some countries, a thesis is associated with a bachelor’s or master’s degree, while a dissertation is typically required for a doctoral degree.

Is there a specific word count for a thesis?

While there is no universal word count for a thesis , institutions may provide guidelines on the expected length based on the type of degree and academic discipline. It’s essential to adhere to the specified word count to meet academic standards.

How does the length of a thesis vary across different fields of study?

The length of a thesis can differ based on the field of study and the nature of the research being conducted. For example, a thesis in the social sciences may be shorter compared to one in a scientific or technical field that requires extensive data analysis and documentation.

Dissertation vs. thesis  

While dissertation and thesis are sometimes used interchangeably, they actually refer to two different pieces of writing. A thesis is traditionally completed at the end of a master’s program . It is based on pre-existing research and showcases your ability to understand the information you have been learning about in your program. 

A dissertation is much longer than a thesis and is completed at the end of a PhD or doctorate program . It is the last thing you need to complete in order to earn your doctorate in your chosen field. It will be about a topic of your choosing that is within your field of study. Instead of using all pre-existing information though, you will conduct a portion of your own research and propose new ideas.

See also : Top scholarships for graduate students   

What do you write about when completing a dissertation?

What you write about will depend on what field of study you are in. A dissertation is designed to be your own. Meaning that what you write about should be a new idea, a new topic, or question that is still unanswered in your field. Something that you will need to collect new data on, potentially interview people for and explore what information is already available.  

Generally, an idea will need to be approved or at least discussed with whoever is overseeing your dissertation before you begin writing. It’s important to put time and effort into choosing a topic that you will be able to find either existing research for and add to, or a topic that you will be able to establish your own methods of data collection for. Again, the goal of your dissertation is to add to your field.   

How long does a dissertation need to be?  

Your dissertation length will vary, but you can generally count on it to be around 2-3 times the length of your thesis. A standard thesis is roughly 80 to 100 pages. So, on the short end you’re looking at a 200 pages dissertation, while the longer end can reach as high as 400 pages.  

How long does it take to write?  

The page count for a dissertation is enough to scare even the best writers away, but take a breath and rest easy knowing that this is not something you complete in just one semester or even two. On the short end you will have a year to write your dissertation, while the longer end can offer as much as two years to complete your dissertation. During this time, you will work with an advisor who can watch over you and help you along the way.  

The parts of a dissertation   

A dissertation is not just one long paper you must write. Thankfully, it is broken down into manageable pieces that you complete over time.  

Choosing a topic  

The first thing you will do is come up with your topic. Again, your topic will need to be approved by whoever is overseeing your dissertation. If they think that it may not be a strong topic, they will let you know. Even if a topic is approved though, you’ll need to do research around that topic first to make sure that it has not already been covered, or if it has that you take into consideration what has been done and add to the topic in a new way.  

Research can mean looking at what already exists, as well as conducting your own research to add to a proposed idea of yours. Your research can take many different forms depending on what field you are in. Research can be costly at times, so be sure to check out what funding opportunities are available for doctoral research. There are even post PhD research grants you should be familiar with if you intend to continue researching.  

Chapter break down  

A dissertation generally consists of five chapters. We’ve written them out below with a brief description of each and what they include.   

Introduction – Just as you would expect, this is where you will introduce your topic and what you plan to discuss  

Literature review – This section will address the research you have found that has already been done, or found has not been done, that pertains to your topic  

Methodology – How you go about collecting information for your dissertation, whether it be conducting your own research or delving deep into what has already been done, will be discussed in the methodology section 

Results – Your results will analyze the information you gathered  in regard to your topic 

Discussion – Finally, your discussion section will assess the meaning of your results and it is also where you will add your own ideas, rooted in research, about what those results mean in a broader context in regard to your field 

There will be more parts of your dissertation that are not included in the chapters, but the bulk of your dissertation will be made up by these five chapters. Things like title pages, references, appendices, and table of contents will also be included.  

Defending your dissertation  

Believe it or not, it’s not enough just to write your dissertation–you also have to defend your dissertation. This is another reason why taking a thorough amount of time to choose your topic is so important. You’ll likely need to propose your initial dissertation idea, but that will be much simpler and shorter. Your final defense will be much lengthier and in depth.  

During your defense, you will present your dissertation to a committee. It’s likely that you’ll be at least somewhat familiar with those on the committee; they are not just randomly picked. They will ask you questions about your research, and you will need to respond to each question. A defense generally takes around two hours. The point of a defense is not to have people try to undermine your work, but for you to exemplify your expertise in your field.  

Failing your dissertation  

Nobody wants to think about failing, but unfortunately, you can fail your dissertation. However, let’s talk about a few things before we just leave it at that. First, if you are afraid of failing your dissertation, this is something that you should speak to your advisor about. They can help you determine if there should be legitimate concerns or if you are getting in your own head.  

Second, even if you do fail your dissertation, you are usually allowed to resubmit one time. This of course is not ideal, but it does give you a little room to breathe. Your goal is to do great from the start, but remember this is not an easy task. You’ll likely have plenty of bumps along the way! 

Again, if you have concerns about failing, address them sooner rather than later and seek help. There are bound to be plenty of people and services around you, as well as additional services that you can pay for which will help review your materials and guide you along.

Key Takeaways

• Dissertations are completed as the last step of your PhD or doctorate degree 
• Your dissertation will be related to a topic or question in your field of study that you choose 
• Dissertations take anywhere from one to two years to complete and can be upwards of three hundred pages long 
• Your dissertation is designed to showcase your expertise in your field and your addition of new ideas to the field about a particular question or area

How Long Does it Take to Write a Dissertation? [2024 Guide]

Reading through the requirements for a PhD program may prompt you to ask, “How long does it take to write a dissertation?”

You probably already know that this is a major project, but you may be curious about how much of your life you’ll need to commit to the process.

Editorial Listing ShortCode:

Dissertation writing can vary significantly from one student to the next. Even still, learning more about dissertations can help you have a better idea of what you can expect in terms of time commitment and workload.

How Long Does It Take to Write a Dissertation?

Before you sit down to write your PhD dissertation, it makes sense to figure out approximately how long the process is going to take you. That way, you can approach this project with reasonable expectations in mind.

Having an idea of the common timeframe for dissertations may also encourage you to set realistic goals. Many students write their dissertations within 1 to 2 years. In other words, once you reach All But Dissertation (ABD) status, you might be less than 2 years away from completing your PhD program.

You might be anxious to type your dissertation in less than 12 months so that you can move on with your life. While that’s understandable, you may be putting undue pressure on yourself. In fact, your school may require you to spend at least a year on your dissertation.

It’s also possible that you expect to need more than 2 years. As long as you keep moving, that’s okay. Just remember to check your university’s rules. Some schools set a time limit on doctoral enrollment.

No matter how long the process takes, you’ll go through multiple steps as you work toward your goal:

• Selecting a topic
• Reviewing relevant literature
• Developing a research project
• Conducting research and analyzing the data you gather
• Outlining your paper
• Writing the first draft
• Editing and producing a final draft

You may begin some of these steps, such as deciding on your topic, during the coursework portion of your program. Eventually, though, you’ll move into ABD status, and it will be time to focus solely on the dissertation.

Some students lose motivation at that point. If life is too busy, your wallet feels too strained, or you don’t have a good support system, you may feel like throwing in the towel. It can be especially tempting to quit if the project simply feels too overwhelming. To try and avoid these obstacles to finishing your PhD, it can help to make a plan for writing your dissertation.

You can break the project down into steps, carve out writing time, set attainable goals, and move progressively closer to a final product of which you’ll be proud.

Tips for Dissertation Writing

The answer to “How long does a dissertation take?” depends in large part on your process. Putting the following tips into practice may help you finish more quickly:

• Understand the assignment . Reading other people’s dissertations can help you get a feel for what you’ll be doing yourself.
• Dive in early . The sooner you start working on this project, the sooner you’ll be able to finish.
• Craft an outline . Organizing your thoughts into a workable dissertation structure can make all the difference.
• Schedule daily sessions . It’s strategic to make sure you write a bit each day. Some people recommend 2 hours of daily writing, but that’s not the best fit for everyone. Figure out how much time you can commit, and pencil it into your calendar.
• Stretch your legs . Even during a marathon writing session, it helps to give yourself breaks. You might take a quick walk or do some stretches.
• Get excited about your goals . It’s beneficial to break your process down into milestones and celebrate each time you achieve one.

Finally, it helps to surround yourself with a great support team—such as family, friends, and your faculty advisor—to whom you can turn when times feel tough.

How Long Is a Dissertation?

Each student’s dissertation is a slightly different length. Typically, though, most dissertations are between 100 and 300 pages long. It’s common for them to include about 80,000 words. Some are closer to 100,000 words.

Your school may set guidelines for the length of your paper. The requirements may even vary from one department to the next. For example, dissertations in the natural or physical sciences are often under 100 pages. Dissertations in fields like theology and history commonly contain several hundred pages.

The content will be broken into various chapters, such as the introduction, the methodology, and the results.

What’s the Difference Between a Doctoral Dissertation vs. Thesis?

The words “thesis” and “dissertation” are often used in similar contexts. You can think about which one you’ll be writing during your doctoral studies.

While a dissertation is the standard final project for a PhD, theses are more common at the master’s degree level. In addition, some programs don’t require a dissertation, like several online doctoral programs in education without dissertation , but require a capstone.

Writing a Dissertation

Whether you are just beginning the PhD journey or have reached ABD status , there’s a dissertation in your future.

Yes, writing a dissertation is a task that is going to take a significant amount of time and effort. But now that you have a better idea of what to expect, you are one step closer to your goal. You can make a plan, block out time, and get your dissertation written.

Remember to surround yourself with support and ask for help as needed. Cheer yourself on throughout the process, and celebrate each milestone. It may take a few years, but you can accomplish this goal!

When you’ve finished your coursework, as well as any comprehensive exams or other requirements, you advance to “ABD” (All But Dissertation) status. This means you’ve completed everything except your dissertation.

Prior to starting to write, you must form your committee and write your prospectus or proposal . Your committee comprises your adviser and a few other faculty members. They can be from your own department, or, if your work is more interdisciplinary, from other departments. Your committee will guide you through the dissertation process, and ultimately decide whether you pass your dissertation defense and receive your PhD.

Your prospectus is a formal document presented to your committee, usually orally in a defense, outlining your research aims and objectives and showing why your topic is relevant . After passing your prospectus defense, you’re ready to start your research and writing.

Prevent plagiarism. Run a free check.

The structure of your dissertation depends on a variety of factors, such as your discipline, topic, and approach. Dissertations in the humanities are often structured more like a long essay , building an overall argument to support a central thesis , with chapters organized around different themes or case studies.

However, hard science and social science dissertations typically include a review of existing works, a methodology section, an analysis of your original research, and a presentation of your results , presented in different chapters.

The abstract is a short summary of your dissertation, usually about 150 to 300 words long. Though this may seem very short, it’s one of the most important parts of your dissertation, because it introduces your work to your audience.

Your abstract should:

• State your main topic and the aims of your research
• Describe your methods
• Summarize your main results
• State your conclusions

Read more about abstracts

The table of contents lists all of your chapters, along with corresponding subheadings and page numbers. This gives your reader an overview of your structure and helps them easily navigate your document.

Remember to include all main parts of your dissertation in your table of contents, even the appendices. It’s easy to generate a table automatically in Word if you used heading styles. Generally speaking, you only include level 2 and level 3 headings, not every subheading you included in your finished work.

Read more about tables of contents

While not usually mandatory, it’s nice to include a list of figures and tables to help guide your reader if you have used a lot of these in your dissertation. It’s easy to generate one of these in Word using the Insert Caption feature.

Read more about lists of figures and tables

Similarly, if you have used a lot of abbreviations (especially industry-specific ones) in your dissertation, you can include them in an alphabetized list of abbreviations so that the reader can easily look up their meanings.

Read more about lists of abbreviations

In addition to the list of abbreviations, if you find yourself using a lot of highly specialized terms that you worry will not be familiar to your reader, consider including a glossary. Here, alphabetize the terms and include a brief description or definition.

Read more about glossaries

The introduction serves to set up your dissertation’s topic, purpose, and relevance. It tells the reader what to expect in the rest of your dissertation. The introduction should:

• Establish your research topic , giving the background information needed to contextualize your work
• Narrow down the focus and define the scope of your research
• Discuss the state of existing research on the topic, showing your work’s relevance to a broader problem or debate
• Clearly state your research questions and objectives
• Outline the flow of the rest of your work

Everything in the introduction should be clear, engaging, and relevant. By the end, the reader should understand the what, why, and how of your research.

Read more about introductions

A formative part of your research is your literature review . This helps you gain a thorough understanding of the academic work that already exists on your topic.

Literature reviews encompass:

• Finding relevant sources (e.g., books and journal articles)
• Assessing the credibility of your sources
• Critically analyzing and evaluating each source
• Drawing connections between them (e.g., themes, patterns, conflicts, or gaps) to strengthen your overall point

A literature review is not merely a summary of existing sources. Your literature review should have a coherent structure and argument that leads to a clear justification for your own research. It may aim to:

• Address a gap in the literature or build on existing knowledge
• Take a new theoretical or methodological approach to your topic
• Propose a solution to an unresolved problem or advance one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework. Here, you define and analyze the key theories, concepts, and models that frame your research.

Read more about theoretical frameworks

Your methodology chapter describes how you conducted your research, allowing your reader to critically assess its credibility. Your methodology section should accurately report what you did, as well as convince your reader that this was the best way to answer your research question.

A methodology section should generally include:

• The overall research approach ( quantitative vs. qualitative ) and research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment )
• Details of where, when, and with whom the research took place
• Any tools and materials you used (e.g., computer programs, lab equipment)
• Your data analysis methods (e.g., statistical analysis , discourse analysis )
• An evaluation or justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. You can structure this section around sub-questions, hypotheses , or themes, but avoid including any subjective or speculative interpretation here.

Your results section should:

• Concisely state each relevant result together with relevant descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Briefly state how the result relates to the question or whether the hypothesis was supported
• Report all results that are relevant to your research questions , including any that did not meet your expectations.

Additional data (including raw numbers, full questionnaires, or interview transcripts) can be included as an appendix. You can include tables and figures, but only if they help the reader better understand your results. Read more about results sections

Your discussion section is your opportunity to explore the meaning and implications of your results in relation to your research question. Here, interpret your results in detail, discussing whether they met your expectations and how well they fit with the framework that you built in earlier chapters. Refer back to relevant source material to show how your results fit within existing research in your field.

Some guiding questions include:

• What do your results mean?
• Why do your results matter?
• What limitations do the results have?

If any of the results were unexpected, offer explanations for why this might be. It’s a good idea to consider alternative interpretations of your data.

Read more about discussion sections

Your dissertation’s conclusion should concisely answer your main research question, leaving your reader with a clear understanding of your central argument and emphasizing what your research has contributed to the field.

In some disciplines, the conclusion is just a short section preceding the discussion section, but in other contexts, it is the final chapter of your work. Here, you wrap up your dissertation with a final reflection on what you found, with recommendations for future research and concluding remarks.

It’s important to leave the reader with a clear impression of why your research matters. What have you added to what was already known? Why is your research necessary for the future of your field?

Read more about conclusions

It is crucial to include a reference list or list of works cited with the full details of all the sources that you used, in order to avoid plagiarism. Be sure to choose one citation style and follow it consistently throughout your dissertation. Each style has strict and specific formatting requirements.

Common styles include MLA , Chicago , and APA , but which style you use is often set by your department or your field.

Create APA citations Create MLA citations

Your dissertation should contain only essential information that directly contributes to answering your research question. Documents such as interview transcripts or survey questions can be added as appendices, rather than adding them to the main body.

Read more about appendices

Making sure that all of your sections are in the right place is only the first step to a well-written dissertation. Don’t forget to leave plenty of time for editing and proofreading, as grammar mistakes and sloppy spelling errors can really negatively impact your work.

Dissertations can take up to five years to write, so you will definitely want to make sure that everything is perfect before submitting. You may want to consider using a professional dissertation editing service , AI proofreader or grammar checker to make sure your final project is perfect prior to submitting.

After your written dissertation is approved, your committee will schedule a defense. Similarly to defending your prospectus, dissertation defenses are oral presentations of your work. You’ll present your dissertation, and your committee will ask you questions. Many departments allow family members, friends, and other people who are interested to join as well.

After your defense, your committee will meet, and then inform you whether you have passed. Keep in mind that defenses are usually just a formality; most committees will have resolved any serious issues with your work with you far prior to your defense, giving you ample time to fix any problems.

As you write your dissertation, you can use this simple checklist to make sure you’ve included all the essentials.

Institutional guidelines on dissertation length 

You can think of institutional guidelines as purveyors of academic excellence. Ever wondered why schools impose specific requirements like "Chapter 1: The Introduction must be at least 35 pages long and no more than 50 pages"? 

It's not just about arbitrary rules! However, it's about striking the perfect balance between guidance and practicality. These guidelines serve as guardrails, steering students like you towards scholarly success without overwhelming faculty with endless pages to peruse. 

Moreover, credibility is key here! A mere 8-page literature review won't cut it in the realm of academia. But fear not, for most institutions provide dissertation templates, complete with essential headings to streamline the process. 

And for those seeking a helping hand, a dissertation writing service like ours stands ready to assist, ensuring your masterpiece meets the lofty standards of academic rigor. So, embrace the guidelines, weave your narrative, and let your dissertation shine with scholarly prowess.

Variations in dissertation length across academic disciplines

Dissertation length varies significantly across academic disciplines due to differences in research methods, data presentation, and writing conventions. Here's a general overview of how dissertation length can differ by discipline:

• Humanities and Social Sciences: Dissertations in these fields tend to be longer because they often involve comprehensive literature reviews, detailed theoretical analyses, and extensive qualitative data. It's not uncommon for dissertations in history, literature, or sociology to exceed 200 pages.
• Sciences and Engineering: Dissertations in the sciences and engineering might be shorter in terms of page count but are dense with technical details, data, charts, and appendices. They often range between 100 to 200 pages. However, the length can vary significantly depending on the complexity of the work and the requirements of the specific program.
• Arts and Design: In creative disciplines, the dissertation might include a practical component (like a portfolio, exhibition, or performance) alongside a written thesis. The written component might be shorter, focusing on the conceptual and contextual analysis of the creative work, usually ranging from 40 to 80 pages.
• Professional Fields (Business, Education, etc.): Dissertations in professional fields such as business or education often focus on case studies, practical applications, and policy analysis. These dissertations can vary widely in length but often fall in the range of 100 to 200 pages.

Dissertations vary in length due to many factors, which shows the diverse nature of academic research. Disciplinary differences are significant, as each field may have distinct expectations regarding the depth and scope of the study. 

The type of analysis conducted, whether qualitative, quantitative, or a combination of both, also impacts the length. 

For instance, qualitative studies may involve extensive textual analysis, resulting in longer manuscripts, while quantitative studies may require detailed statistical analyses. Additionally, the specific area of research within a discipline can also affect the length, as certain topics may necessitate more:

• extensive literature reviews
• data collection (e.g., fieldwork, surveys, interviews, lab work)
• discussion sections

While the average length typically falls within the range of 150-300 pages, it's essential to recognize the nuanced factors contributing to variations in dissertation length. You must remain informed about the variables shaping your document's overall size and structure to deliver exemplary results.

Factors influencing the length of doctoral dissertations

Various factors determine the length of a dissertation, such as the specific guidelines set by universities, the type of research conducted, the extent of analysis required, and the presence of supplementary materials.

Several factors come into play when determining the ideal length of a dissertation. University guidelines set the tone, with institutions offering word count ranges typically between 8,000 to 15,000 words for undergraduates and masters and 75,000 to 100,000 words for PhD. 

Yet, beyond these guidelines, the nature of your research holds sway.

Disciplines vary, with humanities favoring extensive literature reviews and scientific fields emphasizing methodological intricacies. Depth of analysis matters, too; a thorough exploration demands more space. 

Balancing these elements ensures a well-rounded dissertation. So, as you embark on your scholarly journey, consider these factors carefully. By understanding them, you'll craft a dissertation that not only meets academic standards but also showcases your analytical prowess and depth of intelligence.

Length, components, and scholarly dedication

Many aspiring scholars think, "How long is a doctoral dissertation?" However, the answer isn't straightforward. Yes, length varies, but let's not forget to factor in a crucial element: time. And we know because many students have instructed us to “ write my dissertation !”

Remember, a dissertation isn't penned in one sitting. Rather, it often evolves from smaller academic chapters. This gradual process allows students to explore diverse topics before committing to a book-length project they're passionate about.

Beyond the central argument lie various components that contribute to the overall length. Take the literature review, for example—an essential segment that contextualizes the research by analyzing existing scholarship. Then there's the myriad of ancillary elements like the title page, acknowledgments, abstract, and appendix, each adding to the dissertation's page count.

It’s the accumulation of these parts that determines the length. So, while the answer may not be a precise number, it's crucial to acknowledge many elements that make up a doctoral dissertation. And for those embarking on this scholarly journey, we can help you conquer this challenge.

How Long is a Dissertation Chapter? Uncover the Mystery

When it comes to dissertation length, most grad students fret over how long each chapter should be. While there's no one-size-fits-all answer, there is a golden rule–chapters should be long enough to address the research question comprehensively. 

Think quality over quantity! Ask any dissertation adviser, and they’ll say aiming to fill a predetermined number of pages shouldn’t be the goal. Rather, you must thoroughly explore your topic, conduct extensive research, and present your findings effectively. 

Your writing style and the unique nature of your research also play pivotal roles. So, whether your chapter spans 50 pages or 150, ensure it's packed with substantive content that advances your study. Ultimately, it's not about hitting a page count but about delivering a high-quality scholarly contribution.

Writing an Excellent PhD Dissertation: Strategies and Tips

After you’re done pondering on how many pages should a dissertation be, you can move on with production. Wondering how to write a dissertation , here are some tips:

Remember, with meticulous planning and dedication, you'll produce a dissertation that makes you and your mentors proud. 

How long is a PhD dissertation?: The Conundrum

Do you belong to the list of students who feel bewildered about PhD dissertation length? Many wonder because of the length’s variability across disciplines and institutions. The general ballpark figure for a completed doctoral dissertation is typically between 150 to 300 pages. Yet, this can vary widely depending on factors such as: 

• field of study
• research methodology used
• individual institutional requirements
• guidelines of mentors

Although there's no one-size-fits-all answer, understanding these variables can help you navigate the ambiguity surrounding dissertation length. And with proper planning, you can create an impressive output.

If you’re pressed for time, you can buy dissertation online . Just ensure to give appropriate instructions so the final output adheres to your institution's formatting guidelines. With these supporting materials appropriately included, your dissertation will be comprehensive.

Are there different types of dissertations? 

When asking how long are dissertations, one of the first things to consider is the field of study. Various types of dissertations exist, often shaped by research methodology. It can be quantitative to qualitative studies or triangulation (a blend of both). 

Instead of worrying about the length, determine your research approach—whether it's primary or secondary, qualitative or quantitative. This decision significantly impacts the depth and breadth of your investigation, ultimately influencing the expected length of your dissertation. By aligning your research methods with your academic goals, you'll gain clarity on the scope of your writing project. 

Another aspect of the length of the entire document is the type of thesis - be it an undergraduate thesis, masters thesis, or thesis for an advanced degree, most dissertations for academic programs are lengthy. The more advanced the degree, the longer the thesis usually is.

Are dissertations just for PhDs? 

How many pages in a dissertation is something most students worry about. But is a dissertation just for doctoral candidates? In some countries, dissertations are exclusive to PhDs. However, for other countries, the term “dissertation” is interchangeable with "thesis." Why so?

Because both are research projects completed for undergraduate or postgraduate degrees. Keep in mind that whether you’re pursuing a bachelor's, an MA, or a doctorate, dissertation writing demonstrates your research skills and academic proficiency.

Your doctoral degree, just like your graduate degree from a graduate school, shows you can successfully navigate the research process, theoretical framework, and dissertation defense. Sure, the scope of research was less focused while you were a graduate student with a master's thesis. Nonetheless, it shows consistent work and dedication.

How many chapters in a dissertation? 

Still mulling over how long does a dissertation have to be and how many chapters you must write? Dissertations usually consist of five to seven chapters. These typically cover the following: 

• introduction
• literature review
• methodology

However, the structure can vary depending on your field of study and specific institutional guidelines. Each chapter plays a vital role, leading readers through your research journey, from laying the groundwork to presenting findings and drawing conclusions.

Dissertation Explained: A Grad Student’s Guide

Updated: June 19, 2024

Published: March 10, 2020

Higher education is filled with milestones. When completing your PhD , you will be required to complete a dissertation. Even if you’ve heard this word thrown around before, you still may be questioning “What is a dissertation?” It’s a common question, especially for those considering to join or are already in a graduate program. As such, here’s everything you need to know about dissertations.

What is a Dissertation?

A dissertation is a written document that details research. A dissertation also signifies the completion of your PhD program. It is required to earn a PhD degree, which stands for Doctor of Philosophy.

A PhD is created from knowledge acquired from:

1. Coursework:

A PhD program consists of academic courses that are usually small in size and challenging in content. Most PhD courses consist of a high amount and level of reading and writing per week. These courses will help prepare you for your dissertation as they will teach research methodology.

2. Research:

For your dissertation, it is likely that you will have the choice between performing your own research on a subject , or expanding on existing research. Likely, you will complete a mixture of the two. For those in the hard sciences, you will perform research in a lab. For those in humanities and social sciences, research may mean gathering data from surveys or existing research.

3. Analysis:

Once you have collected the data you need to prove your point, you will have to analyze and interpret the information. PhD programs will prepare you for how to conduct analysis, as well as for how to position your research into the existing body of work on the subject matter.

4. Support:

The process of writing and completing a dissertation is bigger than the work itself. It can lead to research positions within the university or outside companies. It may mean that you will teach and share your findings with current undergraduates, or even be published in academic journals. How far you plan to take your dissertation is your choice to make and will require the relevant effort to accomplish your goals.

Moving from Student to Scholar

In essence, a dissertation is what moves a doctoral student into becoming a scholar. Their research may be published, shared, and used as educational material moving forwards.

Thesis vs. Dissertation

Basic differences.

Grad students may conflate the differences between a thesis and a dissertation.

Simply put, a thesis is what you write to complete a master’s degree. It summarizes existing research and signifies that you understand the subject matter deeply.

On the other hand, a dissertation is the culmination of a doctoral program. It will likely require your own research and it can contribute an entirely new idea into your field.

Structural Differences

When it comes to the structure, a thesis and dissertation are also different. A thesis is like the research papers you complete during undergraduate studies. A thesis displays your ability to think critically and analyze information. It’s less based on research that you’ve completed yourself and more about interpreting and analyzing existing material. They are generally around 100 pages in length.

A dissertation is generally two to three times longer compared to a thesis. This is because the bulk of the information is garnered from research you’ve performed yourself. Also, if you are providing something new in your field, it means that existing information is lacking. That’s why you’ll have to provide a lot of data and research to back up your claims.

Your Guide: Structuring a Dissertation

Dissertation length.

The length of a dissertation varies between study level and country. At an undergraduate level, this is more likely referred to as a research paper, which is 10,000 to 12,000 words on average. At a master’s level, the word count may be 15,000 to 25,000, and it will likely be in the form of a thesis. For those completing their PhD, then the dissertation could be 50,000 words or more.

Format of the dissertation.

Here are the items you must include in a dissertation. While the format may slightly vary, here’s a look at one way to format your dissertation:

1. Title page:

This is the first page which includes: title, your name, department, degree program, institution, and submission date. Your program may specify exactly how and what they want you to include on the title page.

2. Acknowledgements:

This is optional, but it is where you can express your gratitude to those who have helped you complete your dissertation (professors, research partners, etc.).

3. Abstract:

The abstract is about 150-300 words and summarizes what your research is about. You state the main topic, the methods used, the main results, and your conclusion.

4. Table of Contents

Here, you list the chapter titles and pages to serve as a wayfinding tool for your readers.

5. List of Figures and Tables:

This is like the table of contents, but for graphs and figures.

6. List of Abbreviations:

If you’ve constantly abbreviated words in your content, define them in a list at the beginning.

7. Glossary:

In highly specialized work, it’s likely that you’ve used words that most people may not understand, so a glossary is where you define these terms.

8. Introduction:

Your introduction sets up the topic, purpose, and relevance. It’s where readers will understand what they expect to gain from your dissertation.

9. Literature Review / Theoretical Framework:

Based on the research you performed to create your own dissertation, you’ll want to summarize and address the gaps in what you researched.

10. Methodology

This is where you define how you conducted your research. It offers credibility for you as a source of information. You should give all the details as to how you’ve conducted your research, including: where and when research took place, how it was conducted, any obstacles you faced, and how you justified your findings.

11. Results:

This is where you share the results that have helped contribute to your findings.

12. Discussion:

In the discussion section, you explain what these findings mean to your research question. Were they in line with your expectations or did something jump out as surprising? You may also want to recommend ways to move forward in researching and addressing the subject matter.

13. Conclusion:

A conclusion ties it all together and summarizes the answer to the research question and leaves your reader clearly understanding your main argument.

14. Reference List:

This is the equivalent to a works cited or bibliography page, which documents all the sources you used to create your dissertation.

15. Appendices:

If you have any information that was ancillary to creating the dissertation, but doesn’t directly fit into its chapters, then you can add it in the appendix.

Drafting and Rewriting

As with any paper, especially one of this size and importance, the writing requires a process. It may begin with outlines and drafts, and even a few rewrites. It’s important to proofread your dissertation for both grammatical mistakes, but also to ensure it can be clearly understood.

It’s always useful to read your writing out loud to catch mistakes. Also, if you have people who you trust to read it over — like a peer, family member, mentor, or professor — it’s very helpful to get a second eye on your work.

How is it Different from an Essay?

There are a few main differences between a dissertation and an essay. For starters, an essay is relatively short in comparison to a dissertation, which includes your own body of research and work. Not only is an essay shorter, but you are also likely given the topic matter of an essay. When it comes to a dissertation, you have the freedom to construct your own argument, conduct your own research, and then prove your findings.

Types of Dissertations

You can choose what type of dissertation you complete. Often, this depends on the subject and doctoral degree, but the two main types are:

This relies on conducting your own research.

Non-empirical:

This relies on studying existing research to support your argument.

More things you should know.

A dissertation is certainly no easy feat. Here’s a few more things to remember before you get started writing your own:

1. Independent by Nature:

The process of completing a dissertation is self-directed, and therefore can feel overwhelming. However, if you approach it like the new experience that it is with an open-mind and willingness to learn, you will make it through!

2. Seek Support:

There are countless people around to offer support. From professors to peers, you can always ask for help throughout the process.

3. Writing Skills:

The process of writing a dissertation will further hone your writing skills which will follow you throughout your life. These skills are highly transferable on the job, from having the ability to communicate to also developing analytical and critical thinking skills.

4. Time Management:

You can work backwards from the culmination of your program to break down this gargantuan task into smaller pieces. That way, you can manage your time to chip away at the task throughout the length of the program.

5. Topic Flexibility:

It’s okay to change subject matters and rethink the point of your dissertation. Just try as much as possible to do this early in the process so you don’t waste too much time and energy.

The Wrap Up

A dissertation marks the completion of your doctoral program and moves you from being a student to being a scholar. While the process is long and requires a lot of effort and energy, you have the power to lend an entirely new research and findings into your field of expertise.

As always, when in the thick of things, remember why you started. Completing both your dissertation and PhD is a commendable accomplishment.

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How long are thesis statements? [with examples]

What is the proper length of a thesis statement?

Examples of thesis statements, frequently asked questions about the length of thesis statements, related articles.

If you find yourself in the process of writing a thesis statement but you don't know how long it should be, you've come to right place. In the next paragraphs you will learn about the most efficient way to write a thesis statement and how long it should be.

A thesis statement is a concise description of your work’s aim.

The short answer is: one or two sentences. The more i n-depth answer: as your writing evolves, and as you write longer papers, your thesis statement will typically be at least two, and often more, sentences. The thesis of a scholarly article may have three or four long sentences.

The point is to write a well-formed statement that clearly sets out the argument and aim of your research. A one sentence thesis is fine for shorter papers, but make sure it's a full, concrete statement. Longer thesis statements should follow the same rule; be sure that your statement includes essential information and resist too much exposition.

Here are some basic rules for thesis statement lengths based on the number of pages:

• 5 pages : 1 sentence
• 5-8 pages : 1 or 2 sentences
• 8-13 pages : 2 or 3 sentences
• 13-23 pages : 3 or 4 sentences
• Over 23 pages : a few sentences or a paragraph

Joe Haley, a former writing instructor at Johns Hopkins University exemplified in this forum post the different sizes a thesis statement can take. For a paper on Jane Austen's  Pride and Prejudice,  someone could come up with these two theses:

In Jane Austen's  Pride and Prejudice , gossip is an important but morally ambiguous tool for shaping characters' opinions of each other.

As the aforementioned critics have noted, the prevalence of gossip in Jane Austen's  oeuvre  does indeed reflect the growing prominence of an explicitly-delineated private sphere in nineteenth-century British society. However, in contrast with these critics' general conclusions about Austen and class, which tend to identify her authorial voice directly with the bourgeois mores shaping her appropriation of the  bildungsroman,  the ambiguity of this communicative mode in  Pride and Prejudice  suggests that when writing at the height of her authorial powers, at least, Austen is capable of skepticism and even self-critique. For what is the narrator of her most celebrated novel if not its arch-gossip  par excellence ?

Both statements are equally sound, but the second example clearly belongs in a longer paper. In the end, the length of your thesis statement will depend on the scope of your work.

There is no exact word count for a thesis statement, since the length depends on your level of knowledge and expertise. A two sentence thesis statement would be between 20-50 words.

The length of the work will determine how long your thesis statement is. A concise thesis is typically between 20-50 words. A paragraph is also acceptable for a thesis statement; however, anything over one paragraph is probably too long.

Here is a list of Thesis Statement Examples that will help you understand better how long they can be.

As a high school student, you are not expected to have an elaborate thesis statement. A couple of clear sentences indicating the aim of your essay will be more than enough.

Here is a YouTube tutorial that will help you write a thesis statement: How To Write An Essay: Thesis Statements by Ariel Bisset.

Dissertation Structure & Layout 101: How to structure your dissertation, thesis or research project.

By: Derek Jansen (MBA) Reviewed By: David Phair (PhD) | July 2019

So, you’ve got a decent understanding of what a dissertation is , you’ve chosen your topic and hopefully you’ve received approval for your research proposal . Awesome! Now its time to start the actual dissertation or thesis writing journey.

To craft a high-quality document, the very first thing you need to understand is dissertation structure . In this post, we’ll walk you through the generic dissertation structure and layout, step by step. We’ll start with the big picture, and then zoom into each chapter to briefly discuss the core contents. If you’re just starting out on your research journey, you should start with this post, which covers the big-picture process of how to write a dissertation or thesis .

*The Caveat *

In this post, we’ll be discussing a traditional dissertation/thesis structure and layout, which is generally used for social science research across universities, whether in the US, UK, Europe or Australia. However, some universities may have small variations on this structure (extra chapters, merged chapters, slightly different ordering, etc).

So, always check with your university if they have a prescribed structure or layout that they expect you to work with. If not, it’s safe to assume the structure we’ll discuss here is suitable. And even if they do have a prescribed structure, you’ll still get value from this post as we’ll explain the core contents of each section.  

Overview: S tructuring a dissertation or thesis

• Acknowledgements page
• Abstract (or executive summary)
• Table of contents , list of figures and tables
• Chapter 1: Introduction
• Chapter 2: Literature review
• Chapter 3: Methodology
• Chapter 4: Results
• Chapter 5: Discussion
• Chapter 6: Conclusion
• Reference list

As I mentioned, some universities will have slight variations on this structure. For example, they want an additional “personal reflection chapter”, or they might prefer the results and discussion chapter to be merged into one. Regardless, the overarching flow will always be the same, as this flow reflects the research process , which we discussed here – i.e.:

• The introduction chapter presents the core research question and aims .
• The literature review chapter assesses what the current research says about this question.
• The methodology, results and discussion chapters go about undertaking new research about this question.
• The conclusion chapter (attempts to) answer the core research question .

In other words, the dissertation structure and layout reflect the research process of asking a well-defined question(s), investigating, and then answering the question – see below.

To restate that – the structure and layout of a dissertation reflect the flow of the overall research process . This is essential to understand, as each chapter will make a lot more sense if you “get” this concept. If you’re not familiar with the research process, read this post before going further.

Right. Now that we’ve covered the big picture, let’s dive a little deeper into the details of each section and chapter. Oh and by the way, you can also grab our free dissertation/thesis template here to help speed things up.

The title page of your dissertation is the very first impression the marker will get of your work, so it pays to invest some time thinking about your title. But what makes for a good title? A strong title needs to be 3 things:

• Succinct (not overly lengthy or verbose)
• Specific (not vague or ambiguous)
• Representative of the research you’re undertaking (clearly linked to your research questions)

Typically, a good title includes mention of the following:

• The broader area of the research (i.e. the overarching topic)
• The specific focus of your research (i.e. your specific context)
• Indication of research design (e.g. quantitative , qualitative , or  mixed methods ).

For example:

A quantitative investigation [research design] into the antecedents of organisational trust [broader area] in the UK retail forex trading market [specific context/area of focus].

Again, some universities may have specific requirements regarding the format and structure of the title, so it’s worth double-checking expectations with your institution (if there’s no mention in the brief or study material).

Acknowledgements

This page provides you with an opportunity to say thank you to those who helped you along your research journey. Generally, it’s optional (and won’t count towards your marks), but it is academic best practice to include this.

So, who do you say thanks to? Well, there’s no prescribed requirements, but it’s common to mention the following people:

• Your dissertation supervisor or committee.
• Any professors, lecturers or academics that helped you understand the topic or methodologies.
• Any tutors, mentors or advisors.
• Your family and friends, especially spouse (for adult learners studying part-time).

There’s no need for lengthy rambling. Just state who you’re thankful to and for what (e.g. thank you to my supervisor, John Doe, for his endless patience and attentiveness) – be sincere. In terms of length, you should keep this to a page or less.

Abstract or executive summary

The dissertation abstract (or executive summary for some degrees) serves to provide the first-time reader (and marker or moderator) with a big-picture view of your research project. It should give them an understanding of the key insights and findings from the research, without them needing to read the rest of the report – in other words, it should be able to stand alone .

For it to stand alone, your abstract should cover the following key points (at a minimum):

• Your research questions and aims – what key question(s) did your research aim to answer?
• Your methodology – how did you go about investigating the topic and finding answers to your research question(s)?
• Your findings – following your own research, what did do you discover?
• Your conclusions – based on your findings, what conclusions did you draw? What answers did you find to your research question(s)?

So, in much the same way the dissertation structure mimics the research process, your abstract or executive summary should reflect the research process, from the initial stage of asking the original question to the final stage of answering that question.

In practical terms, it’s a good idea to write this section up last , once all your core chapters are complete. Otherwise, you’ll end up writing and rewriting this section multiple times (just wasting time). For a step by step guide on how to write a strong executive summary, check out this post .

Table of contents

This section is straightforward. You’ll typically present your table of contents (TOC) first, followed by the two lists – figures and tables. I recommend that you use Microsoft Word’s automatic table of contents generator to generate your TOC. If you’re not familiar with this functionality, the video below explains it simply:

If you find that your table of contents is overly lengthy, consider removing one level of depth. Oftentimes, this can be done without detracting from the usefulness of the TOC.

Right, now that the “admin” sections are out of the way, its time to move on to your core chapters. These chapters are the heart of your dissertation and are where you’ll earn the marks. The first chapter is the introduction chapter – as you would expect, this is the time to introduce your research…

It’s important to understand that even though you’ve provided an overview of your research in your abstract, your introduction needs to be written as if the reader has not read that (remember, the abstract is essentially a standalone document). So, your introduction chapter needs to start from the very beginning, and should address the following questions:

• What will you be investigating (in plain-language, big picture-level)?
• Why is that worth investigating? How is it important to academia or business? How is it sufficiently original?
• What are your research aims and research question(s)? Note that the research questions can sometimes be presented at the end of the literature review (next chapter).
• What is the scope of your study? In other words, what will and won’t you cover ?
• How will you approach your research? In other words, what methodology will you adopt?
• How will you structure your dissertation? What are the core chapters and what will you do in each of them?

These are just the bare basic requirements for your intro chapter. Some universities will want additional bells and whistles in the intro chapter, so be sure to carefully read your brief or consult your research supervisor.

If done right, your introduction chapter will set a clear direction for the rest of your dissertation. Specifically, it will make it clear to the reader (and marker) exactly what you’ll be investigating, why that’s important, and how you’ll be going about the investigation. Conversely, if your introduction chapter leaves a first-time reader wondering what exactly you’ll be researching, you’ve still got some work to do.

Now that you’ve set a clear direction with your introduction chapter, the next step is the literature review . In this section, you will analyse the existing research (typically academic journal articles and high-quality industry publications), with a view to understanding the following questions:

• What does the literature currently say about the topic you’re investigating?
• Is the literature lacking or well established? Is it divided or in disagreement?
• How does your research fit into the bigger picture?
• How does your research contribute something original?
• How does the methodology of previous studies help you develop your own?

Depending on the nature of your study, you may also present a conceptual framework towards the end of your literature review, which you will then test in your actual research.

Again, some universities will want you to focus on some of these areas more than others, some will have additional or fewer requirements, and so on. Therefore, as always, its important to review your brief and/or discuss with your supervisor, so that you know exactly what’s expected of your literature review chapter.

Now that you’ve investigated the current state of knowledge in your literature review chapter and are familiar with the existing key theories, models and frameworks, its time to design your own research. Enter the methodology chapter – the most “science-ey” of the chapters…

In this chapter, you need to address two critical questions:

• Exactly HOW will you carry out your research (i.e. what is your intended research design)?
• Exactly WHY have you chosen to do things this way (i.e. how do you justify your design)?

Remember, the dissertation part of your degree is first and foremost about developing and demonstrating research skills . Therefore, the markers want to see that you know which methods to use, can clearly articulate why you’ve chosen then, and know how to deploy them effectively.

Importantly, this chapter requires detail – don’t hold back on the specifics. State exactly what you’ll be doing, with who, when, for how long, etc. Moreover, for every design choice you make, make sure you justify it.

In practice, you will likely end up coming back to this chapter once you’ve undertaken all your data collection and analysis, and revise it based on changes you made during the analysis phase. This is perfectly fine. Its natural for you to add an additional analysis technique, scrap an old one, etc based on where your data lead you. Of course, I’m talking about small changes here – not a fundamental switch from qualitative to quantitative, which will likely send your supervisor in a spin!

You’ve now collected your data and undertaken your analysis, whether qualitative, quantitative or mixed methods. In this chapter, you’ll present the raw results of your analysis . For example, in the case of a quant study, you’ll present the demographic data, descriptive statistics, inferential statistics , etc.

Typically, Chapter 4 is simply a presentation and description of the data, not a discussion of the meaning of the data. In other words, it’s descriptive, rather than analytical – the meaning is discussed in Chapter 5. However, some universities will want you to combine chapters 4 and 5, so that you both present and interpret the meaning of the data at the same time. Check with your institution what their preference is.

Now that you’ve presented the data analysis results, its time to interpret and analyse them. In other words, its time to discuss what they mean, especially in relation to your research question(s).

What you discuss here will depend largely on your chosen methodology. For example, if you’ve gone the quantitative route, you might discuss the relationships between variables . If you’ve gone the qualitative route, you might discuss key themes and the meanings thereof. It all depends on what your research design choices were.

Most importantly, you need to discuss your results in relation to your research questions and aims, as well as the existing literature. What do the results tell you about your research questions? Are they aligned with the existing research or at odds? If so, why might this be? Dig deep into your findings and explain what the findings suggest, in plain English.

The final chapter – you’ve made it! Now that you’ve discussed your interpretation of the results, its time to bring it back to the beginning with the conclusion chapter . In other words, its time to (attempt to) answer your original research question s (from way back in chapter 1). Clearly state what your conclusions are in terms of your research questions. This might feel a bit repetitive, as you would have touched on this in the previous chapter, but its important to bring the discussion full circle and explicitly state your answer(s) to the research question(s).

Next, you’ll typically discuss the implications of your findings . In other words, you’ve answered your research questions – but what does this mean for the real world (or even for academia)? What should now be done differently, given the new insight you’ve generated?

Lastly, you should discuss the limitations of your research, as well as what this means for future research in the area. No study is perfect, especially not a Masters-level. Discuss the shortcomings of your research. Perhaps your methodology was limited, perhaps your sample size was small or not representative, etc, etc. Don’t be afraid to critique your work – the markers want to see that you can identify the limitations of your work. This is a strength, not a weakness. Be brutal!

This marks the end of your core chapters – woohoo! From here on out, it’s pretty smooth sailing.

The reference list is straightforward. It should contain a list of all resources cited in your dissertation, in the required format, e.g. APA , Harvard, etc.

It’s essential that you use reference management software for your dissertation. Do NOT try handle your referencing manually – its far too error prone. On a reference list of multiple pages, you’re going to make mistake. To this end, I suggest considering either Mendeley or Zotero. Both are free and provide a very straightforward interface to ensure that your referencing is 100% on point. I’ve included a simple how-to video for the Mendeley software (my personal favourite) below:

Some universities may ask you to include a bibliography, as opposed to a reference list. These two things are not the same . A bibliography is similar to a reference list, except that it also includes resources which informed your thinking but were not directly cited in your dissertation. So, double-check your brief and make sure you use the right one.

The very last piece of the puzzle is the appendix or set of appendices. This is where you’ll include any supporting data and evidence. Importantly, supporting is the keyword here.

Your appendices should provide additional “nice to know”, depth-adding information, which is not critical to the core analysis. Appendices should not be used as a way to cut down word count (see this post which covers how to reduce word count ). In other words, don’t place content that is critical to the core analysis here, just to save word count. You will not earn marks on any content in the appendices, so don’t try to play the system!

Time to recap…

And there you have it – the traditional dissertation structure and layout, from A-Z. To recap, the core structure for a dissertation or thesis is (typically) as follows:

• Acknowledgments page

Most importantly, the core chapters should reflect the research process (asking, investigating and answering your research question). Moreover, the research question(s) should form the golden thread throughout your dissertation structure. Everything should revolve around the research questions, and as you’ve seen, they should form both the start point (i.e. introduction chapter) and the endpoint (i.e. conclusion chapter).

I hope this post has provided you with clarity about the traditional dissertation/thesis structure and layout. If you have any questions or comments, please leave a comment below, or feel free to get in touch with us. Also, be sure to check out the rest of the  Grad Coach Blog .

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

How Long Is a Dissertation? Here’s the Average Length

How long is a dissertation? This is a question that you’re likely to ask if you’ve just enrolled for a doctoral program. But, this question is not new because other students have asked it too. Perhaps, the simplest answer to this question is that a dissertation should be sufficiently long to answer the stated question satisfactorily.

How Long Is a Dissertation?

There is no single answer to the question of a doctoral dissertation length. But most dissertations are on average 100-200 pages long. Somebody can say it should be 146 pages while somebody else can say 90 pages. Another person can say it should be 200 pages. Essentially, the length of this important academic document should depend on the topic, writing style, and goals of the writer.

Universities require students to write dissertations when pursuing masters and PhD degree programs. This paper forms an invaluable part of these academic programs in reputable learning institutions. As such, most undergraduate students are worried about the length of this document because it forms an important aspect of their academic life.

There are generally practical suggestions about how long should a dissertation be. For instance, the areas that your dissertation project focuses on should influence its length. For instance, a dissertation on a history topic will most likely be longer than an average dissertation on a chemistry topic. That means your academic discipline will influence the length of your dissertation.

How Long Is a PhD Dissertation?

Most academicians say that a PhD dissertation length should not exceed 80, 000 words . Thus, your text should be near this length. This word count includes the appendices while excluding references, footnotes, and bibliography. The footnotes of a dissertation shouldn’t exceed 20% of the text.

Students are discouraged from including discursive footnotes. What’s more, they should not use footnotes to include materials that should be in their main text. Doing so would circumvent the average length of the dissertation.

The statistical tables of a dissertation are counted as around 150 words each . But, the Degree Committee can allow learners to exceed the limits after application and under exceptional situations. Therefore, students should apply for this exception early before the date they propose to submit their thesis. The Graduate Committee evaluates the application and decides whether to allow the student to alter the average dissertation length.

The committee considers the dissertation proposal, as well as, a signed statement attesting to their proposed dissertation length. If they don’t and their dissertation exceeds the average length, it will be referred back for revision before it is forwarded to the institution’s examiners.

Average Dissertation Length

Many factors should generally be considered when answering the question of how long is a PhD dissertation. However, students should limit their writing between 80,000 and 100,000 words . On average, this document should have around 204 pages. But, the average length of a PhD thesis also depends on the university and the specific subject.

Essentially, a university can set the requirements of a dissertation, including the length. Nevertheless, most institutions opt for around 100,000 words. Research has shown that STEM dissertations have a medium length of 159 pages. Non-STEM dissertations, on the other hand, have a medium length of about 223 pages. Thus, there is a significant difference in length between STEM and non-STEM dissertations.

How Long Is a Dissertation Chapter?

Another question that might be lingering in your mind is how long is a dissertation chapter? Well, this varies because each chapter is a separate section that should address something specific. If you include the right information succinctly and adequately, your final write-up should have the right length. So, how long is a doctoral dissertation in every section? Here is a rough estimate.

Introduction

This section of a dissertation should tell readers why the topic is important. It should also mention relevant facts about the topic. Essentially, the introduction should tell readers why you have chosen the topic or issue and what makes it relevant. On average, the introduction should be between 10 and 15 pages . This is a perfect size because it allows you to mention everything concisely. Focus on intriguing the audience without disclosing or revealing anything in detail. Thus, your dissertation introduction should be more of a teaser.

Literature review

This is the section where you analyze relevant sources that you have chosen for your paper. It should include only sources that can be used to write the dissertation. In this section, you analyze and point out the strengths and weaknesses of your chosen sources. The literature review should be between 20 and 25 pages long.

Methodology

The length of this part of a dissertation ranges from 10 to 15 pages . It focuses on the methods used to conduct the research. Here, you discuss the specific method and data-selection processes used. This section also includes ways of contacting the sample population, as well as, the gathered data. What’s more, the encountered challenges can be included.

This section of a dissertation should not exceed 10 pages . It features the list and clarification of the obtained findings. Research findings are mentioned alongside the hypotheses explicitly. For instance, you should state whether they were refuted or confirmed. This section should also include a conclusion for everything done as far as your investigation is concerned.

This is also called the discussion section. Its length should range between 15 and 20 pages . This is the section where you explain the implications of your research. Provide a current and bigger perspective regarding your research. What’s more, diversify the current evidence base regarding the topic. Also, provide recommendations while acknowledging limitations in this section.

So, how long is a dissertation chapter? Well, it boils down to factors of the topic, learning institution, and goals of the study. Each section varies in length based on the nature of the research conducted and gathered data.

But, exactly how long does a dissertation have to be? There is no clear answer to this question. However, psychology, history, communication, nursing, and management dissertation can be up to 300 pages long. Education, Environmental Health, and Political Science dissertations can be around 100 pages. Overall, this length is influenced by the nature of the conducted research and the data that must be included in the document.

How Long Should a Dissertation Proposal Be?

You’re no longer asking how long is a dissertation word count because this question has been answered. But, you probably want to know the length of its proposal. Well, there is no specific length for this document. However, it should be considered as a long, formal treatise.

Well, most faculties recommend between 15 and 20 pages . However, the length of a proposal should depend on factors like the problem to be pursued, reasons to address the problem, where the answers will come from, and why you will go for certain sources.

This document proposes the work to be done. The focus of this text should be on convincing the thesis committee of your faculty that you have a research question that’s worth pursuing. Thus, you must present a convincing document for your faculty to allow you to proceed with the dissertation writing project. So, how long should it be?

How Long Should a Dissertation Abstract Be?

Lastly, you may want to know how long the abstract section of your dissertation should be. This is a separate page of the entire document. It is a summary of the dissertation. It reports the outcomes and aims of the research. Essentially, readers should know what your document is all about by reading the abstract. As such, this section should be written at the end. It should state the research objectives, problem, methods, key results, and the conclusion.

The dissertation abstract length ranges between 150 and 300 words . But just like with the main sections of a dissertation, there is a strict limit on the number of words that can be included. Therefore, check with the journal or university for which you are writing the dissertation.

• Researching and Writing a Masters Dissertation

Written by Mark Bennett

All Masters programmes include some form of extended individual project. Research-focussed programmes, such as an MRes , may include multiple independent research components. Taught courses usually culminate with a substantial research task, referred to as the Masters dissertation or thesis.

This article talks about how long a Masters dissertation is and the structure it follows.Before you get started on your dissertation, you'll usually need to write a proposal. Read our full guide to Masters dissertation proposals for more information on what this should include!

What’s the difference between a masters dissertation and an undergraduate dissertation.

The Masters thesis is a bridge between undergraduate study and higher level postgraduate degrees such as the PhD .

A postgraduate dissertation may not look that different to its undergraduate equivalent. You’ll likely have to produce a longer piece of work but the foundations remain the same.

After all, one of the purposes of an undergraduate dissertation or final year project is to prepare you for more in-depth research work as a postgraduate. That said, there are some important differences between the two levels.

So, how long is a Masters dissertation? A Masters dissertation will be longer than the undergraduate equivalent – usually it’ll be somewhere between 15,000 and 20,000 words, but this can vary widely between courses, institutions and countries.

To answer your overall research question comprehensively, you’ll be expected to identify and examine specific areas of your topic. This can be like producing a series of shorter pieces of work, similar to those required by individual modules. However, there’s the additional requirement that they collectively support a broader set of conclusions.

This more involved Masters dissertation structure will:

• Give you the scope to investigate your subject in greater detail than is possible at undergraduate level
• Challenge you to be effective at organising your work so that its individual components function as stages in a coherent and persuasive overall argument
• Allow you to develop and hone a suitable research methodology (for example, choosing between qualitative and quantitative methods)

If the individual topics within your overall project require you to access separate sources or datasets, this may also have an impact on your research process.

As a postgraduate, you’ll be expected to establish and assert your own critical voice as a member of the academic community associated with your field .

During your Masters thesis you’ll need to show that you are not just capable of analysing and critiquing original data or primary source material. You should also demonstrate awareness of the existing body of scholarship relating to your topic .

So, if you’ll excuse the pun, a ‘Masters’ degree really is about achieving ‘mastery’ of your particular specialism and the dissertation is where you’ll demonstrate this: showing off the scholarly expertise and research skills that you’ve developed across your programme.

What’s the difference between a dissertation and a thesis?

A dissertation is a long piece of (usually) written work on the same topic. A thesis is a little more specific: it usually means something that presents an original argument based on the interpretation of data, statistics or content.

So, a thesis is almost always presented as a dissertation, but not all dissertations present a thesis.

Masters dissertation structure

As you can probably imagine, no two dissertations follow the exact same structure, especially given the differences found between Masters programmes from university to university and country to country .

That said, there are several key components that make up the structure of a typical Masters dissertation

How long is a Masters dissertation?

Most dissertations will typically be between 15,000 and 20,000 words long, although this can vary significantly depending on the nature of the programme.

You should also check with your university exactly which sections of the dissertation count towards the final word count (the abstract, bibliography and appendices won’t usually be included in the total).

Usually around 300 words long, the abstract is meant to be a concise summary of your dissertation. It should briefly cover the question(s) you aim to answer, your primary argument and your conclusion.

Introduction

The purpose of the introduction is to provide context for the rest of the dissertation, setting out your aims and the scope of what you want to achieve with your research. The introduction should give a clear overview of the dissertation’s chapters and will usually be around 1,000 words long.

Literature review

This part of the dissertation should examine the scholarship that has already been published in your field, presenting various arguments and counter-arguments while situating your own research within this wider body of work.

You should analyse and evaluate other publications and explain how your dissertation will contribute to the existing literature in your subject area. The literature review sometimes forms part of the introduction or follows immediately on from it. Most literature reviews are up to 1,000 words long.

Research methodology

Not all dissertations will require a section covering research methodology (Arts and Humanities dissertations won’t normally undertake the kind of research that involves a set methodology). However, if you are using a particular method to collect information for your dissertation, you should make sure to explain the rationale behind your choice of methodology. The word count for this part of the dissertation is usually around the 1,500 mark.

Those in the Arts and Humanities will usually outline their theoretical perspectives and approaches as part of the introduction, rather than requiring a detailed explanation of the methodology for their data collection and analysis.

Results / findings

If your research involves some form of survey or experiment, this is where you’ll present the results of your work. Depending on the nature of the study, this might be in the form of graphs, tables or charts – or even just a written description of what the research entailed and what the findings were.

This section forms the bulk of your dissertation and should be carefully structured using a series of related chapters (and sub-chapters). There should be a logical progression from one chapter to the next, with each part building on the arguments of its predecessor.

It can be helpful to think of your Masters dissertation as a series of closely interlinked essays, rather than one overwhelming paper. The size of this section will depend on the overall word count for your dissertation. However, to give you a rough idea for a 15,000-word dissertation, the discussion part will generally be about 12,000 words long.

Here you should draw together the threads of the previous discussion chapters and make your final concluding statements, drawing on evidence and arguments that you’ve already explored over the course of the dissertation. Explain the significance of your findings and point towards directions that future research could follow. This section of the Masters thesis will be around 1,500 words long.

References / bibliography

While planning and writing your dissertation, you should keep an extensive, organised record of any papers, sources or books you’ve quoted (or referred to). This will be a lot easier than leaving all of it until the end and struggling to work out where a particular quotation is from!

Appendices won’t be necessary in many dissertations, but you may need to include supplementary material to support your argument. This could be interview transcripts or questionnaires. If including such content within the body of the dissertation won’t be feasible – i.e. there wouldn’t be enough space or it would break the flow of your writing – you should consult with your supervisor and consider attaching it in an appendix.

It’s worth bearing in mind that these sections won’t always be discretely labelled in every dissertation. For example, everything up to ‘discussion’ might be covered in introductory chapter (rather than as distinct sections). If you’re unsure about the structure of your Masters dissertation, your supervisor will be able to help you map it out.

How does supervision work for a Masters dissertation?

As a Masters student at the dissertation stage you’ll usually be matched with an academic within your institution who will be tasked with guiding your work. This might be someone who has already taught you, or it may be another scholar whose research interests and expertise align well with what you want to do. You may be able to request a particular supervisor, but taught postgraduates are more likely to be assigned them by their department.

Specific arrangements with your supervisor will vary depending on your institution and subject area. They will usually meet with you at the beginning of the dissertation period to discuss your project and agree a suitable schedule for its undertaking. This timetable will probably set dates for:

• Subsequent discussions and progress checks
• The submission of draft chapters or sections
• Feedback appointments

Though your supervisor is there to help and advise you, it is important to remember that your dissertation is a personal research project with associated expectations of you as an independent scholar.

As a rule of thumb, you can expect your supervisor to read each part of your dissertation once at the draft stage and to offer feedback. Most will not have time to look at lots of subsequent revisions, but may respond favourably to polite requests for exceptions (provided their own workload permits it).

Inundating your supervisor with emails or multiple iterations of draft material is best avoided; they will have their own research to manage (as well as other supervision assignments) and will be able to offer better quality feedback if you stick to an agreed schedule.

How is a Masters dissertation assessed and examined?

On most courses your dissertation will be assessed by an external examiner (as well as additional members of faculty within your university who haven’t been responsible for supervising you), but these will read and critique the work you submit without personally questioning and testing you on it.

Though this examination process is not as challenging as the oral defence or ‘ viva voce ’ required for a PhD thesis, the grading of your Masters dissertation is still a fundamental component of your degree.

On some programmes the result awarded to a student’s dissertation may determine the upper grade-band that can be awarded to their degree.

Guide to writing your thesis/dissertation, definition of dissertation and thesis.

The dissertation or thesis is a scholarly treatise that substantiates a specific point of view as a result of original research that is conducted by students during their graduate study. At Cornell, the thesis is a requirement for the receipt of the M.A. and M.S. degrees and some professional master’s degrees. The dissertation is a requirement of the Ph.D. degree.

Formatting Requirement and Standards

The Graduate School sets the minimum format for your thesis or dissertation, while you, your special committee, and your advisor/chair decide upon the content and length. Grammar, punctuation, spelling, and other mechanical issues are your sole responsibility. Generally, the thesis and dissertation should conform to the standards of leading academic journals in your field. The Graduate School does not monitor the thesis or dissertation for mechanics, content, or style.

“Papers Option” Dissertation or Thesis

A “papers option” is available only to students in certain fields, which are listed on the Fields Permitting the Use of Papers Option page , or by approved petition. If you choose the papers option, your dissertation or thesis is organized as a series of relatively independent chapters or papers that you have submitted or will be submitting to journals in the field. You must be the only author or the first author of the papers to be used in the dissertation. The papers-option dissertation or thesis must meet all format and submission requirements, and a singular referencing convention must be used throughout.

ProQuest Electronic Submissions

The dissertation and thesis become permanent records of your original research, and in the case of doctoral research, the Graduate School requires publication of the dissertation and abstract in its original form. All Cornell master’s theses and doctoral dissertations require an electronic submission through ProQuest, which fills orders for paper or digital copies of the thesis and dissertation and makes a digital version available online via their subscription database, ProQuest Dissertations & Theses . For master’s theses, only the abstract is available. ProQuest provides worldwide distribution of your work from the master copy. You retain control over your dissertation and are free to grant publishing rights as you see fit. The formatting requirements contained in this guide meet all ProQuest specifications.

Copies of Dissertation and Thesis

Copies of Ph.D. dissertations and master’s theses are also uploaded in PDF format to the Cornell Library Repository, eCommons . A print copy of each master’s thesis and doctoral dissertation is submitted to Cornell University Library by ProQuest.

Theses and Dissertations

As you embark upon this important element of your academic career, you should be aware of what a dissertation or thesis looks like. After all, how can you write a dissertation chapter if you've never read one before? Advisers often focus on the content of your dissertation or thesis since this is the culmination of a stage of your academic career and as such should showcase your writing, research, and critical thinking skills-but the form of a dissertation or thesis is also important, and commensurately more difficult to teach.

For every discipline there are differing expectations as to what a dissertation or thesis should include, as well as how it should be formatted. Even though as a writer you have control over how to explain your ideas and how to organize them within the text, scholars in your field have agreed upon how a dissertation/thesis should be organized: what types of chapters you should include, the minimum number of chapters a dissertation or thesis should have, and how those are formatted. This is where seeing and reading what other writers within your discipline and department have done will be helpful. You should do this sooner rather than later.

Getting Started: 

• Start by asking your adviser if they have any suggestions of dissertations or theses you should look at. They may point you to things like the writings of an ex-advisee or a certain literature review article in a journal.
• After speaking to your adviser, you can seek out either a reference librarian or a subject librarian to find other dissertations or theses in your subject area. Find out more about how to access completed dissertations and theses at Dissertations and Theses at KU . 
• Reading not just for content but also for form will help you understand better how to put together your dissertation or thesis. Learn about thesis and dissertation formatting via  KU Libraries: Thesis and Dissertation Formatting . 
• Think about how the project as a whole is organized as well as how the individual chapters are organized: how do they separate their literature review from their discussion of their results, for example? Do they utilize headings and subheadings or bulleted lists at any point?
• Moreover, take notes about elements of the project that stand out to you: use of tables, inclusion of photographs, striking introductions, chapter titles.
• Based on what you know so far, brainstorm ideas for what to include in your project and how those ideas can be organized. See Prewriting Strategies.  

Finding and Synthesizing Sources: 

Produce a research question that you hope your research will answer. If you are at the beginning stage of this process, you may have a general or vague question or set of questions. Eventually you want to create a set of questions that focus on a specific problem within your area of interest and join an existing academic conversation. 

Begin researching. The KU Libraries has many guides and tutorials for how to use the library resources. You can also set up a meeting with a librarian . 

Compile a list of sources that seem to approach your subject of interest. In the beginning you may want to compile at least a list of 10 sources and to organize them in a matrix or an annotated bibliography where you note the subject matter of the source, its novel argument, its theoretical relationship to the subject and field, and what may be lacking within the analysis. At a later stage, you may want to synthesize what is different between each source and similar to all the sources you compile and decide on the specific problem you want your research to cover based on the existing viewpoints and conversations on the topic. Find more information on Annotated Bibliographies in our Bibliographies guide. 

Find data and a data source that is appropriate and compatible with your research problem and question. If you are collecting your own data, make sure that you complete the appropriate protocols to ensure that your project will be completed within the intended timeframe.  

Keep track of your sources through citation management tools like EndNote and Zotero. See How to Select and Use Citation Management Tools . 

Additional steps will depend on the kind of project you are completing. At this point it may be a good idea to meet with the Graduate Writing Coach for more guidance on additional steps.

Literature Reviews: 

The point of the literature review section of your thesis or dissertation is to demonstrate an understanding of the ongoing conversations, disagreements, and conceptualizations of your topic of interest. As a form of writing that tends to be highly technical, it will probably undergo several changes before you are able to reach a draft that closely resembles your final product. Your literature review should directly correspond to your research questions, research purpose, and may be used to justify the methodology of the study. Learn more through our Literature Reviews guide. 

Getting Feedback: 

Stuck in your writing process? You may benefit from a consultation with our graduate writing director. To schedule a meeting and for more information see the following: Graduate Writing Coaching | KU Writing Center  

Faculty Feedback: Throughout your thesis and dissertation process you will have to keep consistent communication with your advisor/chair and committee members. It is important to view all faculty feedback throughout this process as a conversation that will allow your research to both improve and reach the required conventions of research in your field. If you find yourself stuck with contradictory comments or unclear questions, you may want to reach out to your advisor for additional help. If you have questions throughout this process, you may also want to consider making a coaching appointment with the graduate writing director at the link above.   

Time Management: 

It is important that you learn and intentionally prioritize your thesis and dissertation research and writing.  

Set aside a direct weekly block to complete your thesis/dissertation hours.  

Use SMARTER goals to help you keep track of your progress and to split the larger semester goal into weekly goals that can be measured, are concrete, and remain specific.  

Time-block your calendar so that you can set aside concrete time to finish your weekly writing goal and to block off time to complete your other responsibilities.  

Find an accountability buddy within your department, have consistent check-in sessions with your advisor or committee member, and/or join a KU writing group to help you stay on track.
