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:
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:
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.

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.
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.
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.
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 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.
A PhD dissertation is the essential part of a research-based degree since it reflects the student’s knowledge and experience in the field. However, there are some subtle areas that can be frustrating and misleading for many students PhD students. One of the key aspects of the dissertation is its length. Typically, the standard PhD dissertation is 60,000-80,000 words in length, but there is no one size fits all solution. What is definitely known is that a PhD thesis is significantly larger than an MA dissertation. However, it is important to note that PhD thesis writing is about critical analysis, novelty in research and quality of writing. Hence, the PhD writing should firstly focus on the quality of research rather than quantity. This article aims to find out the recommended length of a dissertation at a PhD level.
Many students are looking for PhD help and high-quality writing services and size of the thesis is one of the most difficult questions to answer. When talking about PhD thesis writing, it is important to emphasise the depth of research and comprehensive analysis of all theories and points. This means that size of a dissertation depends on the specific project requirements. For some dissertations that focus heavily on theoretical considerations, the size is likely to be higher. In this case, there is a lot more past literature to be reviewed and more theories to consider. More empirical works rely on a slightly different approach to thesis writing. In this case, the thesis is expected to be a little bit shorter but more empirical. That is, the key value of the thesis comes from empirical findings rather than theoretical review. Therefore, there are different approaches to writing dissertations thereby affecting length of the thesis. However, the minimum length is about 60,000 words, but the key focus is on the depth of research.
In addition, the length of a dissertation depends on the subject area. For more research-intensive subject areas, there is more information to include in the dissertation. This naturally leads to higher length of the thesis. For areas with much previous literature attention the word count is likely to be larger because of more massive literature review and more opportunities for research. Some new projects with the lack of the academic focus in the past can be shorter. Thesis writing for a social sciences course implies probably larger project size compared to the thesis for science or medicine. Nevertheless, there is no strict answer to this question on the size of a PhD dissertation. There are different factors that come into play and the subject area is one of them.
Another important factor to consider is the university and its PhD dissertation rules and word limits. PhD thesis writing is similar across universities but there are some notable differences. Some universities allow for more strict word limits such as 75,000-80,000 words. Others set higher word limits of 100,000 words or more. Generally, university or course requirements influence size of a PhD thesis. This means that there is no one answer on the size of the thesis paper. Each university has its own standards for PhD thesis writing, so there are significant variations across universities.
The question on how long the PhD dissertation should be is not new. Moreover, each year there are thousands of students who ask exactly the same question. The simple answer can be – “long enough to properly answer the question”. This means that there is no one size that fits all theses. The length of the paper depends on the subject area and university. In addition, depth of research also affects the thesis writing and length of a PhD thesis. Most of theses range from 70,000 to 100,000 words in size. However, each student should consult with his/her faculty on the project size.

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.

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

Feng Long defends her thesis: The Fraxinus excelsior mycobiome Zoom link Supervisors: Professor Lene Rostgaard Nielsen, IGN Professor Erik Dahl Kjær, IGN Associate Professor Chatchai Kosawang, IGN Associate Professor James Doonan, IGN Assessment Committee: Professor Isabella Børja, NIMBIO and NMBU – Norway Associate Professor Rimvydas Vasaitis, SLU - Sweden Lektor Hans Jørgen Lyngs Jørgensen (chair), PLEN Summary (shortened): In recent years, a growing body of evidence has demonstrated the role of fungal symbionts in modulating plant host resistance against abiotic and biotic stress, such as drought tolerance and defense against fungal pathogens. These studies have generated interest in tree-associated fungal communities, also known as the tree mycobiome. The most well-studied tree-fungi relationship is that of mycorrhizal fungi, which enhance tree vigor through nutrient uptake facilitation and pathogen antagonism. Despite the widespread focus on mycorrhizal fungi, some endophytic fungi also have protective roles against a variety of plant pathogens, through, for example, the production of anti-fungal secondary metabolites. However, mycobiome communities must survive in the face of changing environmental conditions. For instance, climatic factors, including drought and high temperature, can alter the fungal species within each community. Climate change can also affect soil properties, such as pH and nutrient availability, which can again modify the mycobiome community structure. Trees can shape the structure of their associated mycobiome, and microbes can be transferred from the mother to the next generation, and trees with different genetic backgrounds may select distinct fungi, even within the same species. In Manuscript I, I hypothesized that mother ash trees disperse different sets of mycobiomes via their seed wings. The rationale behind testing the hypothesis was to better understand the early dispersal of the seed mycobiome of ash trees with different levels of ash dieback susceptibility. In common ash, the function of the samara is to enhance seed dispersal and it is spread together with the seed itself, while most of the seed stalk remains on the mother tree. The seeds were collected from two genotypes of common ash. The endophytic fungal community of seed wing and stalk were profiled and analyzed with ITS1-based amplicon sequencing in this manuscript. Seed wing had a higher richness than seed stalk within genotypes, while neither the diversity between the mycobiomes from the two tissue types nor the two genotypes were significantly different. Furthermore, the mycobiome composition differed between seed wings of the two genotypes, while seed stalks were not significantly different. Therefore, the results suggested that F. excelsior mother trees dispersed different sets of endophytic fungi through their samaras. Finally, in Manuscript IV, I conducted a greenhouse study to explore the function of forest soils in ash seedling growth and drought tolerance in comparison to other soil types. I hypothesized that the forest soil mycobiome could benefit ash seedling growth in comparison to potting and agriculture soil. I further hypothesized that soil type and drought stress can affect the rootassociated fungal community and furthermore that these communities can recover after rewatering. The rationale behind testing the hypothesis was to explore the implications of expected extreme weather conditions, including droughts, on ash seedling vigor. The results showed that soil type and drought stress influenced the photosynthesis of ash seedlings, and the seedlings grown in forest soil had higher stomatal conductance (gs), CO2 assimilation, and transpiration. In contrast, the total CO2 assimilation was lower in forest soil than in the other two soil types under drought conditions. Moreover, soil type affected ash growth in response to drought stress and rewatering. The total plant biomass in forest soil was lower after rewatering, while the root/shoot ratio increased to be higher than in the other two soil types after rewatering. Furthermore, soil type affected leaf C, N, P, K, Mg content and C/N ratio (P < 0.001) in response to drought stress, but not leaf Ca. The mycobiome composition of the root endosphere and rhizosphere was significantly affected by soil types and drought stress, although only the root endosphere mycobiome was significantly influenced by rewatering. The correlation between the root endo- and rhizosphere fungal community and soil properties indicated that soil pH, C, N, and C/N ratio could explain the variations. These findings suggest that ash seedlings modulate the root-associated mycobiome via plant-soil-microbe interaction during drought scenarios.
