how long are masters thesis papers

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.

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.

How to Write a Thesis: A Guide for Master’s Students

By Dr. David James Kritz   |  09/29/2023

Let’s face it. Researching and writing a quality thesis can be daunting for many reasons, including:

• A lack of knowledge on where to begin the assignment process
• What key arguments and questions to ask in relation to the thesis statement
• How to get to the data and subject matter
• How to cope with writer's block, a professor's expectations, and time constraints

According to Dictionary.com , a thesis is “a proposition stated or put forward for consideration, especially one to be discussed and proved or to be maintained against objections.”

Therefore, avoiding a weak thesis statement is vital when writing an applicable paper. Thesis statement examples are pivotal in understanding this position.

Currently, master’s students who select the thesis capstone within American Public University's School of Security and Global Studies intelligence master's degree program must choose a relevant subject.

Typically, these students must write a thesis statement that consists of at least one compelling sentence and at least 50 pages of content, then turn it in within 16 weeks.

I have taught graduate students, primarily from the U.S. Intelligence Community, how to conduct research for over eight years.

Based on my experience as an educator, I have 10 tips for creating good thesis statements. These tips, combined with some apt thesis statement examples, can elucidate the process.

Tip #1 for Effective Thesis Statements: Select an Appropriate Topic and Research Question

First, it is necessary to use a lengthy thinking process before developing a good thesis statement, whether it’s an expository thesis statement or an argumentative one. This process begins with many questions related to how to write a thesis statement, such as:

• What would be an interesting topic?
• What would be an original and interesting research question?
• What will be the main claim, key arguments, and central idea of the thesis statement?
• What is an appropriate research design?
• How will I get to the data to address my central research question?

Regardless of the thesis statement or topic, all research begins with a research question.

Without the right question, the analysis, literature review, and implications might miss their mark. This question should be unique, intriguing, and beyond a mere “yes” or “no” answer.

For instance, rather than asking, “Will Country X pursue nuclear proliferation?”, it's better to pose open-ended questions like, “How does…?” or “To what extent…?” Such an approach ensures nuanced and substantive answers.

Additionally, supplementary key questions should support the main research question's depth and intent.

Tip #2: Begin Work on the Thesis Statement and Break Up the Thesis into Manageable Sections

After selecting an appropriate topic and developing a central research question for the thesis statement, it is then necessary to apply the research and writing skills you have learned throughout your degree program.

It might be necessary to refine the thesis statement after some preliminary research; after all, you want a strong thesis statement rather than a weak thesis statement.

It is also essential to break up the thesis paper into manageable sections during the writing process. This strategy will help you to overcome the most common types of mental hurdle of creating a thesis paper that can be 50 or more pages in length.

For writing a thesis statement, this way of thinking is helpful before you begin writing. Instead of attempting to write every single sentence of a thesis statement in one long stretch, you can work on one section at a time, turn it in for review and work on the next section of the thesis statement while awaiting feedback.

Tip #3: Pay Attention to Your Professor's Feedback about Your Assignment

When I give my essay assignment to my students with advice on how to write a thesis, I also explain the importance of a strong thesis statement.

I advise them to avoid becoming emotionally attached to the thesis. That emotional attachment can lead to a battle of wills and wits with the capstone course's professor over the thesis statement examples they present.

When it comes to implementing feedback, revisions to the thesis paper often need to occur. Faculty members are there to help guide you and assist you in the production of a good-quality, argumentative thesis statement that will provide new insights for the reader.

Just go with the feedback you receive from your instructor as you write a sentence, or more, and move on to complete your thesis paper more efficiently.

Tip #4: Complete an Abstract

The abstract of a thesis is vital, so it must be carefully crafted. The abstract may be the only section of a published, scholarly paper or article that someone may take the time to read, based on their time constraints and interest.

Ideally, the abstract should be 250 words or less and must contain the main point of the paper. I advise students drafting an abstract for scholarly journal editors to ensure that the abstract has these elements:

An introductory sentence

A “hook” (why the reader should care about the thesis statement or its topic and to motivate the reader to look at your paper)

The central research question to show the main point of your paper

The research design – how you collected evidence to support your arguments

The results and implications, such as the negative and positive aspects of your main topic and the broader context of your research

Tip #5: Write the Literature Review

When crafting a literature review, incorporate multiple peer-reviewed articles from academic sources like ProQuest and EBSCOHost. Opt for articles frequently cited in other works to enhance your paper's credibility.

The review examines arguments in thesis statements and their counterarguments from scholarly works. For clear discussions, organize your review thematically, showing topic synthesis and your position. This reduces confusion.

For example, if 40 articles discuss open-source intelligence and seven focus on social media, that could be a central theme.

Rather than just listing articles, create broader themes and keep synthesizing. When crafting the thesis, evaluate each paragraph's relevance to the main research question. I advise students to assess the “So what?” factor. If a paragraph isn't pertinent, it might be best to remove it.

Tip #6: Develop a Theoretical Framework within Your Thesis Statement

Theories in theses are often mishandled, reflecting a student’s unclear grasp. Academic theory goes beyond mere "I have a theory" statements and leans on robust, time-tested frameworks.

For instance, a strategic intelligence studies thesis statement might employ national security theory or national defense theory. This theory should align with the thesis's central question.

For example, if probing how Country X uses social media for misinformation, a student might be directed to the communication theory, which aligns well with the study's main topic and question.

Tip #7: Select a Research Design

Before conducting research, students must devise a strategy to address their central question. The research design is their roadmap for data collection. This encompasses methodology, methods, and data gathering instruments like surveys or interviews. Research on humans requires IRB approval, which I advise against due to time constraints in a 16-week paper cycle. Additionally, it's vital to distinguish between “methodology” and “methods,” terms often mistakenly used interchangeably.

Methodology involves the justification of the how and why a research method was selected to address the central research question , according to Indeed. The three primary methodologies include:

• Qualitative methodology
• Quantitative methodology
• Mixed methods

“Mixed methods” involves a researcher’s use of at least one research method from a qualitative methodology and another research method from a quantitative methodology, then explaining how those methods will be integrated into a study.

But if two methods from the same methodology are used in a study, that is referred to as a multi-method approach. An example of a multi-method approach would be using a comparative case study as the first qualitative research method and process tracing as the second research method.

Research methods are linked to either qualitative or quantitative methodologies. They focus on “what” a researcher selected to interpret data.

Research method types include:

• Archival records
• Alternative futures
• Case studies
• Comparative case studies
• Content analysis
• Correlational research
• Descriptive research
• Ethnography
• Experimental research
• Phenomenology
• Process tracing

Tip #8: Write about Research Findings and Data

After gathering data for a thesis, analyzing its significance is crucial, with methods including coding. While qualitative methodology doesn't aim to prove anything, unlike the quantitative approach which tests hypotheses, it can discuss correlations, causation, and delve into theoretical implications in data.

Some may view qualitative research as subjective, but selecting variables in quantitative research has its subjectivity too. Ultimately, it's essential to adhere closely to the scientific method, rather than relying on opinions or claims without concrete evidence.

Tip #9: Consider How Bias Will Affect Your Thesis Statement

When writing thesis statements, it is necessary to consider how bias will affect your writing and your reader. Being 100% objective is an admirable goal, but it is impossible to avoid biases as we are human beings.

All of us have biases, including latent ones. At best, we can mitigate biases, such as using coding software, but never holistically remove bias. As researchers, we just need to be aware of biases and develop strategies to mitigate them.

Tip #10: Be Aware of the Limitations of a Study

The study's limitations section is a pivotal part of a thesis. It highlights the research's shortcomings and indicates what might be done differently.

For instance, a student may mention a 16-week time constraint or contemplate a different research design or question.

This section not only helps students recognize how to enhance their research but also guides future scholars. They can learn from prior omissions or envision alternative research avenues.
