Let professional writers deal with your paper, quickly and efficiently.

"How long should a thesis be?" This is perhaps one of the first questions that will cross your mind before you begin writing a thesis paper. Understanding the average length, structure, and expectations will help you stay on track without wasting precious time on unnecessary processes.

Generally, the thesis length varies greatly depending on the academic level and field of study. On average, it ranges from around 40 to 300 pages or approximately 10,000 to 80,000 words. Master's theses tend to be shorter (60-100 pages), while PhD dissertations are usually longer and sometimes hit more than 300 pages.

Below is a quick overview of how long a thesis should be depending on the degree level:

Thesis type	Pages (approx.)	Word count (approx.)
Undergraduate	40-60	10,000-15,000
Master’s	60-100	15,000-40,000
Ph.D. (Doctoral)	150-300	40,000-80,000

While these recommendations are standard, there is no “one size fits all” answer, since different institutions may have their own guidelines. For this reason, we recommend consulting your department or advisor.

In this article, you will find out how long a thesis has to be and what factors determine the volume. But remember that quality and depth of research are more important than simply meeting a page count.

What influences the thesis length?

Multiple factors influence the length of a thesis. Some of the most common elements include:

Degree level The degree level is the biggest factor that impacts the paper count. Undergraduate theses are generally shorter and show your understanding of the basic concepts, while Master’s theses require a more in-depth analysis.
Field of study Various fields require different approaches and explanations. For example, a thesis in mathematics or economics may be shorter as it relies on formulas and data rather than extensive textual explanations. In contrast, subjects like history, English, or anthropology may require longer analysis and discussions.
Research approach & complexity A more complex or interdisciplinary study often requires a longer work to cover all relevant theories, methodologies, and analyses.
University or department requirements Each college has its own set of rules regarding the length and structure of a thesis paper, so be sure to check with your instructor.

These influencing factors will shape how long your thesis ultimately needs to be.

How long should a thesis be: general recommendations

Typically, graduate course advisors offer specific instructions on the number of pages for a thesis paper. The length is usually presented as a range, not a precise page count. For instance it might be 60-100 pages or 15,000-40,000 words for a Master’s thesis paper. If no length is specified, we recommend keeping your graduate thesis around 80-100 pages.

A common mistake students make is focusing solely on meeting the thesis page count, rather than prioritizing content quality. It's essential to conduct thorough research and analysis, and build your work around the core findings. Remember, quality outweighs quantity – a well-organized thesis is far more valuable than simply a word limit.

You should aim to stay within the specified range to demonstrate your ability to adhere to the guidelines. However, falling significantly short of the expected length may suggest that you haven't fully explored your topic.

Recommended thesis length by type

As we have mentioned above, the "correct" length of a thesis mostly depends on its type. Make sure to verify and conform to degree criteria. Let’s see how long an undergraduate or Master’s thesis should be.

Undergraduate thesis length

An undergraduate thesis is usually the shortest type of thesis paper and is usually 40-60 pages or 10,000-15,000 words. This type of work is designed to test your understanding of the course material and present clear argumentation. It may include a literature review, a methodology section, analysis, and conclusion. While preliminary research is necessary, the scope of analysis is often less extensive than at higher levels.

Master’s thesis length

A Master’s thesis is expected to be more comprehensive than an undergraduate thesis. It ranges between 15,000-40,000 words or 60–80 pages. Here, you should demonstrate a deeper understanding of the subject matter and carry out original research or a critical analysis of existing studies.

PhD thesis (doctoral dissertation) length

A PhD thesis or dissertation is the culmination of your degree completion and, thus, is expected to make a significant contribution to the field. As a rule, a PhD thesis is 150-300 pages long (5,000-40,000 words in total). It includes detailed chapters on literature review, methodology, research findings, and discussion. A dissertation is often the most challenging and lengthiest form of research.

How long is each part of a thesis?

There are several parts of a thesis and each of them has its own purpose and suggested length. Since the thesis length requirements can vary significantly, it's helpful to consider the relative proportions of each section rather than fixed page counts. Here's a general breakdown:

Introduction (5-10%): sets up the research question, context, and objectives. Briefly introduces what the reader can expect from the thesis.
Literature review (20-25%): surveys and critically analyzes relevant existing literature to establish the study’s foundation.
Methodology (15-20%): describes how the research was conducted, detailing the approach and techniques used.
Results (10-15%): presents the research outcomes without interpretation.
Discussion (20-25%): analyzes the results and places them in the context of the literature review.
Conclusion (5-10%): summarizes findings, reflects on implications, and suggests areas for further research.

Using thesis length to plan your work

Knowing how long a thesis is supposed to be can help you with planning your timeline and tracking the progress. Here's how you can organize your work using the suggested page count.

Break down the sections. Start by dividing your total page count by the chapters of your thesis. Allocate more space to substantial sections like the literature review and discussion, as they involve more analysis. Shorter sections, such as the abstract, methodology, and conclusion, can be more concise.
Create a detailed outline. Use the length of each section to build a comprehensive outline. This will help you understand the depth needed for each part and keep your writing focused. Having a clear plan in front of your eyes will allow you to cover critical points.
Set milestones and deadlines. Break the whole process into smaller, manageable milestones. For example, aim to complete the introduction within the first two weeks. Then, move on to the literature review over the next month.
Schedule time for research and data collection. Allocate enough time for research, data gathering, and analysis before. If the bulk of your content is based on primary research, plan to collect your data and analyze it early on, which will allow for a more thorough discussion later.
Leave time for revisions and editing. Save at least 1 to 2 weeks at the end of your schedule for final final corrections and editing. Make sure you apply proper formatting.

By using the thesis length as a framework, you can better manage your workload and create a piece that meets both page count and content requirements.

What if my thesis is not long enough?

It’s natural to worry if your thesis doesn’t fulfill the recommended length. However, many professors expect to see the authentic work and the actual effort you put in. If your thesis is slightly under the suggested length, it may still be acceptable as long as it meets the core requirements and presents a strong argument.

Remember, consistency is often better than adding irrelevant content for the sake of word count.

However, whether to accept a shorter thesis depends on your professor or department. If you’re concerned, it’s best to seek feedback from your supervisor early on.

How to make a thesis paper longer?

If you're significantly lacking the word count, the department members may think that you didn't do your best. There are several ways to lengthen your thesis properly. Consider adding extra details, but don’t simply fill in your work with unnecessary material.

Below are some effective strategies.

1. Expand your literature review

It’s always a good idea to revisit your sources and explore additional materials. Critically evaluate studies that are relevant to your research and compare them in more detail.

Good example	Bad example
“In addition to Smith’s (2018) findings, Johnson’s (2019) study provides a contrasting view on the influence of social factors in economic development. Comparing both perspectives highlights a broader debate in the field and adds depth to the argument.”	“Many studies talk about economic development in general without any deeper discussion of specifics. There is a lot of literature on this topic.”

2. Include detailed analysis and case studies

If your Master’s thesis is not as long as it has to be, present more in-depth interpretations, examples, or case studies to support your arguments. Break down your data or findings with comparisons, applications, or counterarguments. This way, you will show different facets of your research.

Good example	Bad example
“By analyzing the economic models of both developed and developing countries, we can better understand the limitations of traditional growth theories in diverse socio-economic contexts.”	“There are many differences between economic models in different countries, which can be explored more.”

3. Add subsections for clarity

If some section is complex or contains multiple ideas, consider breaking it down into subsections. This will not only lengthen the thesis but also make your argument more organized and easier for readers to follow.

For instance, if your "Discussion" chapter contains multiple types of analysis (e.g., social, economic, and environmental implications), divide it into separate subsections like “Social Implications,” “Economic Impact,” and “Environmental Concerns.”

4. Integrate more evidence and examples

Another way to make your college thesis long enough is to use additional data, quotes, or evidence to support your points. Provide examples that illustrate your findings more thoroughly. Do make sure they are directly related to your research question.

Good example	Bad example
“For instance, the implementation of renewable energy policies in Germany and Sweden has led to significant reductions in carbon emissions, as shown in recent environmental studies (Brown, 2020; Green, 2021).”	“Germany and Sweden have made some environmental changes, and they seem to be effective.”

What if my thesis is longer than it’s supposed to be?

If your thesis ends up being longer than recommended, check whether the additional details still support your main argument and stay relevant. However, if the extra content is due to irrelevant material, it’s better to trim it down.

First and foremost, review your work to eliminate any "fluff" or "waterish" content – information that doesn't add any value. A lengthy thesis isn't necessarily better; precision is a key.

Here’s a list of details that may be redundant:

Repeated ideas or statements
Irrelevant background information and side topics
Overly long quotations
Filler words and phrases
Vague or overly complex paragraphs.

How to shorten my thesis paper?

If your thesis is too long, try to prioritize your key arguments and cut down on lengthy explanations or examples that don't add any value. If you can explain the idea using fewer words, choose the shorter version.

Last but not least, seek feedback from your advisor or peers. A fresh pair of eyes can help identify areas that are too wordy and need further improvement.

Final thoughts on how long are thesis papers
