• 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 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.

Dissertation Word Count and Breakdown – How to Stick to the Word Limit Easily

One of the biggest challenges students face when writing a dissertation is managing the word count. Many end up either writing too much or too little.

To avoid this, it’s important to know how many words each chapter of your dissertation should have from the start. With a clear understanding of the dissertation word count breakdown, you can plan your writing schedule and avoid last-minute surprises.

The word limit for dissertations is set by your university. This varies depending on whether you’re writing an undergraduate, master’s, or PhD dissertation. For example, a masters dissertation word count is often between 10,000 and 15,000 words, but some dissertations can be as long as 30,000 words. The undergraduate dissertation word count is usually shorter, while PhD dissertations are longer.

But despite the total dissertation word count allotted, the main problem begins when students have to break down that word ratio into the headings of the dissertation . Here they make the common error of writing more words for a section that can be explained in less count and less count for a section that deserves more words.

How to Stay Within the Dissertation Word Count

A common solution is to use a dissertation word count breakdown calculator available online. These tools allow you to enter your degree level and overall word count, giving you an estimated breakdown for each section.

However, not all online tools are accurate. So, it’s essential to find a reliable calculator that provides correct word distribution. Here’s a quick guide on how to allocate your dissertation word count UK properly.

Dissertation Word Count Breakdown

If you’re working with a 10,000-word dissertation, here’s a recommended word count breakdown for each section:

• Introduction (10% – 1000 words) : The introduction sets the stage for your research. It explains why your topic matters and what you aim to achieve. You should dedicate about 10% of your total word count to this section.
• Literature Review (25% – 2500 words) : The literature review is a critical part of your dissertation, where you discuss previous studies and theories related to your topic. This section should take up around 25% of your word count.
• Methodology (15-20% – 1500 to 2000 words) : The methodology chapter explains how you conducted your research. This should be about 15-20% of your total word count.
• Data Presentation (15% – 1500 words) : In this section, you present the data you’ve collected through your research. Dedicate roughly 15% of your dissertation to this.
• Discussion and Analysis (15-20% – 1500 to 2000 words) : This section is where you interpret your findings and explain their importance. You’ll want to allocate 15-20% of your word count to this part.
• Conclusion and Recommendations (15% – 1500 words) : In the final chapter, you summarize your research and offer recommendations. This section should take up the remaining 15% of your word count.

Manage Your Word Count Effectively

By following this dissertation word count breakdown, you can ensure that each section gets the attention it deserves. This helps you write a well-structured, clear, and coherent dissertation, making it easier to stay within the assigned word limit.

When managing your masters dissertation word count breakdown or any other degree level, remember that planning is key. You can use tools like a dissertation word count breakdown calculator to guide you, but always double-check with your university’s guidelines to make sure you’re on track.

What Is a Dissertation? | 5 Essential Questions to Get Started

Published on 26 March 2020 by Jack Caulfield . Revised on 5 May 2022.

A dissertation is a large research project undertaken at the end of a degree. It involves in-depth consideration of a problem or question chosen by the student. It is usually the largest (and final) piece of written work produced during a degree.

The length and structure of a dissertation vary widely depending on the level and field of study. However, there are some key questions that can help you understand the requirements and get started on your dissertation project.

Table of contents

When and why do you have to write a dissertation, who will supervise your dissertation, what type of research will you do, how should your dissertation be structured, what formatting and referencing rules do you have to follow, frequently asked questions about dissertations.

A dissertation, sometimes called a thesis, comes at the end of an undergraduate or postgraduate degree. It is a larger project than the other essays you’ve written, requiring a higher word count and a greater depth of research.

You’ll generally work on your dissertation during the final year of your degree, over a longer period than you would take for a standard essay . For example, the dissertation might be your main focus for the last six months of your degree.

Why is the dissertation important?

The dissertation is a test of your capacity for independent research. You are given a lot of autonomy in writing your dissertation: you come up with your own ideas, conduct your own research, and write and structure the text by yourself.

This means that it is an important preparation for your future, whether you continue in academia or not: it teaches you to manage your own time, generate original ideas, and work independently.

Prevent plagiarism, run a free check.

During the planning and writing of your dissertation, you’ll work with a supervisor from your department. The supervisor’s job is to give you feedback and advice throughout the process.

The dissertation supervisor is often assigned by the department, but you might be allowed to indicate preferences or approach potential supervisors. If so, try to pick someone who is familiar with your chosen topic, whom you get along with on a personal level, and whose feedback you’ve found useful in the past.

How will your supervisor help you?

Your supervisor is there to guide you through the dissertation project, but you’re still working independently. They can give feedback on your ideas, but not come up with ideas for you.

You may need to take the initiative to request an initial meeting with your supervisor. Then you can plan out your future meetings and set reasonable deadlines for things like completion of data collection, a structure outline, a first chapter, a first draft, and so on.

Make sure to prepare in advance for your meetings. Formulate your ideas as fully as you can, and determine where exactly you’re having difficulties so you can ask your supervisor for specific advice.

Your approach to your dissertation will vary depending on your field of study. The first thing to consider is whether you will do empirical research , which involves collecting original data, or non-empirical research , which involves analysing sources.

Empirical dissertations (sciences)

An empirical dissertation focuses on collecting and analysing original data. You’ll usually write this type of dissertation if you are studying a subject in the sciences or social sciences.

• What are airline workers’ attitudes towards the challenges posed for their industry by climate change?
• How effective is cognitive behavioural therapy in treating depression in young adults?
• What are the short-term health effects of switching from smoking cigarettes to e-cigarettes?

There are many different empirical research methods you can use to answer these questions – for example, experiments , observations, surveys , and interviews.

When doing empirical research, you need to consider things like the variables you will investigate, the reliability and validity of your measurements, and your sampling method . The aim is to produce robust, reproducible scientific knowledge.

Non-empirical dissertations (arts and humanities)

A non-empirical dissertation works with existing research or other texts, presenting original analysis, critique and argumentation, but no original data. This approach is typical of arts and humanities subjects.

• What attitudes did commentators in the British press take towards the French Revolution in 1789–1792?
• How do the themes of gender and inheritance intersect in Shakespeare’s Macbeth ?
• How did Plato’s Republic and Thomas More’s Utopia influence nineteenth century utopian socialist thought?

The first steps in this type of dissertation are to decide on your topic and begin collecting your primary and secondary sources .

Primary sources are the direct objects of your research. They give you first-hand evidence about your subject. Examples of primary sources include novels, artworks and historical documents.

Secondary sources provide information that informs your analysis. They describe, interpret, or evaluate information from primary sources. For example, you might consider previous analyses of the novel or author you are working on, or theoretical texts that you plan to apply to your primary sources.

Dissertations are divided into chapters and sections. Empirical dissertations usually follow a standard structure, while non-empirical dissertations are more flexible.

Structure of an empirical dissertation

Empirical dissertations generally include these chapters:

• Introduction : An explanation of your topic and the research question(s) you want to answer.
• Literature review : A survey and evaluation of previous research on your topic.
• Methodology : An explanation of how you collected and analysed your data.
• Results : A brief description of what you found.
• Discussion : Interpretation of what these results reveal.
• Conclusion : Answers to your research question(s) and summary of what your findings contribute to knowledge in your field.

Sometimes the order or naming of chapters might be slightly different, but all of the above information must be included in order to produce thorough, valid scientific research.

Other dissertation structures

If your dissertation doesn’t involve data collection, your structure is more flexible. You can think of it like an extended essay – the text should be logically organised in a way that serves your argument:

• Introduction: An explanation of your topic and the question(s) you want to answer.
• Main body: The development of your analysis, usually divided into 2–4 chapters.
• Conclusion: Answers to your research question(s) and summary of what your analysis contributes to knowledge in your field.

The chapters of the main body can be organised around different themes, time periods, or texts. Below you can see some example structures for dissertations in different subjects.

• Political philosophy

This example, on the topic of the British press’s coverage of the French Revolution, shows how you might structure each chapter around a specific theme.

This example, on the topic of Plato’s and More’s influences on utopian socialist thought, shows a different approach to dividing the chapters by theme.

This example, a master’s dissertation on the topic of how writers respond to persecution, shows how you can also use section headings within each chapter. Each of the three chapters deals with a specific text, while the sections are organised thematically.

Like other academic texts, it’s important that your dissertation follows the formatting guidelines set out by your university. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

Formatting guidelines concern things like:

• line spacing
• page numbers
• punctuation
• title pages
• presentation of tables and figures

If you’re unsure about the formatting requirements, check with your supervisor or department. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

How will you reference your sources?

Referencing means properly listing the sources you cite and refer to in your dissertation, so that the reader can find them. This avoids plagiarism by acknowledging where you’ve used the work of others.

Keep track of everything you read as you prepare your dissertation. The key information to note down for a reference is:

• The publication date
• Page numbers for the parts you refer to (especially when using direct quotes)

Different referencing styles each have their own specific rules for how to reference. The most commonly used styles in UK universities are listed below.

APA Reference Generator

The words ‘ dissertation ’ and ‘thesis’ both refer to a large written research project undertaken to complete a degree, but they are used differently depending on the country:

• In the UK, you write a dissertation at the end of a bachelor’s or master’s degree, and you write a thesis to complete a PhD.
• In the US, it’s the other way around: you may write a thesis at the end of a bachelor’s or master’s degree, and you write a dissertation to complete a PhD.

The main difference is in terms of scale – a dissertation is usually much longer than the other essays you complete during your degree.

Another key difference is that you are given much more independence when working on a dissertation. You choose your own dissertation topic , and you have to conduct the research and write the dissertation yourself (with some assistance from your supervisor).

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

At the bachelor’s and master’s levels, the dissertation is usually the main focus of your final year. You might work on it (alongside other classes) for the entirety of the final year, or for the last six months. This includes formulating an idea, doing the research, and writing up.

A PhD thesis takes a longer time, as the thesis is the main focus of the degree. A PhD thesis might be being formulated and worked on for the whole four years of the degree program. The writing process alone can take around 18 months.

Is There A Word Limit For Dissertations?

Published by Alvin Nicolas at April 9th, 2024 , Revised On April 9, 2024

Dissertation writing is one of the hardest things to do in academic life. It takes months of hard work and meticulous research. Usually, one of the first questions that students ask about dissertations is, “Is there a word limit for a dissertation?”. Honestly, there is no one-size-fits-all for this. Several factors can impact the word limit of your thesis. This blog intends to answer this query in detail. 

Word Count Variations

While many assume a universal word count for dissertations, the reality is far more complicated. Here’s a breakdown of the key factors that determine the expected word count:

Level Of Study

Undergraduate dissertations typically fall within the range of 8,000-15,000 words, while Master’s dissertations can range from 12,000-50,000 words. PhD theses, on the other hand, are often considered book-length, with expectations hovering around 70,000-100,000 words.

In fields such as STEM (Science, Technology, Engineering, and Mathematics), where empirical research and quantitative analysis are predominant, dissertations may tend to be more concise and focused on presenting empirical findings and statistical analyses. 

Conversely, in disciplines like the humanities and social sciences, where theoretical frameworks and qualitative research methods are prevalent, dissertations may be more extensive and encompass a broader range of literature reviews , theoretical discussions, and case studies.

University Guidelines

Every university has its specific regulations regarding dissertation word count. These guidelines are usually outlined in program handbooks, department websites, or student handbooks. It’s crucial to consult these resources as the primary source of information.

with the advent of digital publishing platforms and online repositories, there has been a growing trend towards electronic theses and dissertations (ETDs). ETDs offer several advantages, including broader accessibility, enhanced searchability, and multimedia integration. 

As a result, some academic institutions have revised their dissertation guidelines to accommodate the unique characteristics of ETDs, allowing for more flexibility in formatting and presentation.

Quality Over Quantity

While word count serves as a general framework, it’s essential to remember that quality ultimately trumps quantity. A concise, well-structured, and impactful dissertation with a lower word count can outperform a lengthy, meandering one that fails to address the research question effectively.

Here are some strategies to ensure your dissertation adheres to quality standards:

• Focus on clarity and conciseness: Express your ideas clearly and concisely, avoiding unnecessary jargon or filler words.
• Prioritise strong arguments and evidence: Ensure your dissertation is well-supported by relevant and credible sources , avoiding irrelevant tangents.
• Structure your argument effectively: Organise your dissertation logically, ensuring a clear flow of information and a strong conclusion .

Pro Tip: Always Ask Your Supervisor

They can also help you refine your arguments, ensure your research is on track, and offer valuable feedback on your writing style and structure.

Schedule regular meetings with your supervisor to discuss your progress, clarify any doubts regarding word count expectations, and seek expert advice on crafting a compelling and impactful dissertation.

Frequently Asked Questions

Do dissertations have word limits.

Yes, dissertations typically have word limits set by academic institutions or specific departments. These limits can vary depending on the level of study and the discipline. Adhering to word limits ensures the dissertation remains focused and manageable for both the student and the examiners.

Is it possible to write a 10k-word dissertation in 2 days?

Writing a 10,000-word dissertation in 2 days is theoretically possible but highly challenging and not advisable. It would require intense focus, organisation, and discipline. However, rushing the process may compromise the quality of research and analysis, impacting the overall academic integrity and evaluation of the work.

How long is the longest dissertation?

The length of the longest dissertation varies, but some exceed 1,000 pages. For instance, in 2015, a Norwegian student, Magnus Carlsen, submitted a mathematics dissertation spanning 500 pages, while Shing-Tung Yau’s mathematics dissertation in 1976 reportedly reached over 1,000 pages. However, such extreme lengths are rare and depend on individual requirements and fields.

How long should a dissertation be?

The length of a dissertation varies widely depending on factors such as academic discipline, institution requirements, and research complexity. Typically, they range from 10,000 to 20,000 words for undergraduate dissertations, 15,000 to 50,000 words for master’s level, and 50,000 to 100,000 words or more for doctoral dissertations.
