How Many Words a Day Does a Dissertation Need?
A 12,000 word undergraduate dissertation needs about 500 words on each writing day. That assumes you work on it two days a week from October until a deadline in early May. Those seven months contain roughly 60 dissertation days. If two in every five of them go on writing and the rest on reading, data and supervision, you have 24 writing days. Spread over those 24 days, 12,000 words come to 500 a day. Allowing for days that fall through raises the number to plan with to about 860.
Five hundred words fill about one and a half double-spaced pages, which is a reasonable afternoon’s work once you know what you want to say. The calculator below works out the same figure for your own word limit and deadline, counting only the days you can give the dissertation each week.
What UK handbooks set
British universities usually set the length of a dissertation in words, and the handbooks state the limit precisely. I read three of them for this article, two from Alliance Manchester Business School (AMBS) and one from the English department at Warwick.
| Course | Word limit | Credits | Not counted towards the limit |
|---|---|---|---|
| AMBS undergraduate dissertation | 12,000, plus or minus 10 per cent | 40 | title page, abstract, contents, footnotes and endnotes, tables and figures, references, appendices |
| AMBS taught master’s dissertation | 8,000 | 60 | title page, contents, abstract, declaration, references, appendices |
| Warwick English, EN3E0 | 9,000 | 30 | abstract, footnotes, bibliography, appendices |
The two AMBS rows surprised me when I put them side by side. The master’s dissertation is the shorter one by 4,000 words, although it carries 60 credits against 40. The level of your degree is therefore a poor guide to the length, and the figure worth planning around is the one in your own handbook. Scribbr gives typical ranges of 8,000 to 15,000 words for an undergraduate dissertation and 12,000 to 50,000 for a master’s, and adds that none of these are strict guidelines.
The handbooks are just as precise about dates. The AMBS master’s handbook sets the deadline to the minute, at 14:00 on Monday 7 September 2026, and expects five supervision meetings that should ideally be finished by mid-July. The AMBS undergraduate handbook schedules a proposal in October, a progress report of 1,000 to 1,500 words in early December and submission in early May. None of the three documents turns the word limit into a weekly or daily amount of writing. The master’s handbook comes closest when it warns that “data collection, literature reviews and reference lists can take longer than you expect”.
How many hours your credits stand for
Every UK module has a credit value, and that value is a statement about time. The Higher Education Credit Framework for England, published by the QAA in 2021, describes one credit as typically equal to 10 hours of notional learning. Notional hours are the time an average student is expected to need, including independent study and assessment.
The AMBS undergraduate handbook applies this directly. Because the dissertation is worth 40 credits, it says, the independent work “should represent 400 hours over the course of the two semesters”. The course outline for the same unit gives about 300 hours of private study, so the two documents do not quite agree. Warwick’s module page lists 300 hours for its 30 credit dissertation.
| Dissertation | Words | Hours budgeted | Hours per 1,000 words |
|---|---|---|---|
| AMBS undergraduate | 12,000 | 400 | 33 |
| Warwick English | 9,000 | 300 | 33 |
| AMBS taught master’s | 8,000 | 600 | 75 |
The two undergraduate courses budget the same time per thousand words, which I had not expected from a business school and an English department. The master’s dissertation gets more than twice as much time for each thousand words.
Most of those hours go on work around the writing. In the example from the opening paragraph, 400 hours spread over about 60 dissertation days come to between six and seven hours a day, which is a full working day on each of your two days. Only part of that time produces new text. The rest goes on reading and analysis, and on revising what is already there.
How the days divide between reading and writing
No handbook I read gives a split between reading and writing. The calculator therefore starts at 40 per cent of your dissertation days for writing, and you can change that share in the menu.
The University of Bath arrives at almost the same figure from the other direction. Its study skills guide on making a dissertation action plan tells students to assume they will write a page a day, at about 500 words a page, and to leave two or more weeks at the end for editing and proofreading. At that pace a 12,000 word dissertation needs 24 writing days, which is exactly what 40 per cent of 60 days gives you.
The right share depends on the kind of dissertation. A dissertation built on texts you already know, as is common in English, can spend close to half of its days on writing from early on. A project with interviews, lab work or an ethics application spends its first months on data, and a share of 25 or 30 per cent is more realistic there. Once the data is in, set the share to 100 per cent and enter only the days that remain.
What a late start does to the number
The daily figure also depends on when the writing days begin. If the reading runs until February, the 24 writing days have to fit into the last twelve weeks before the deadline. The table keeps the 12,000 words and two writing days a week and moves the start of the writing.
| Weeks of writing left | Writing days | Words per writing day |
|---|---|---|
| 12 | 24 | 500 |
| 10 | 20 | 600 |
| 8 | 16 | 750 |
| 6 | 12 | 1,000 |
| 4 | 8 | 1,500 |
| 2 | 4 | 3,000 |
Losing the first two weeks raises the daily figure from 500 to 600, which most people would hardly notice. Losing six weeks doubles it. With four weeks left, the dissertation needs 1,500 words on each of eight days, three times the figure from the opening paragraph.
That last number is high even by the standards of people who set time aside for nothing but writing. In 2018 the NaNoWriMo participants who started a novel, after signing up to write one in a month, averaged 762 words a day, as the article on how many words a day are realistic works out from the organisation’s own figures.
How far to trust your own estimate
Plans like this assume that every writing day actually happens. Roger Buehler, Dale Griffin and Michael Ross tested that assumption on exactly this task in 1994. They asked 37 psychology students at the University of Waterloo, in the final semester of their honours thesis, when they expected to finish. On average the students predicted 33.9 days from the date of the survey and took 55.5. Only 29.7 per cent finished by the date they had given as their most accurate prediction (Buehler, Griffin and Ross, Journal of Personality and Social Psychology, 1994).
33.9 divided by 55.5 is 0.61. The calculator uses this ratio as its buffer and treats 60 per cent of your planned writing days as dependable. In the opening example the 24 writing days become 14, and the daily figure rises from 500 to 858 words.
The sample is small and comes from one university, so the ratio should be read as a rough correction. Bath’s guide gives a similar warning in plainer words when it says that writing up may take “up to three times longer than you expect”. Both sources point the same way, which is why the buffer is switched on by default.
When the limit is given in pages
Some courses, especially outside the UK, set a page limit instead of a word count. The figure usually quoted for a double-spaced page is 250 words, and it comes from typewriters. John Gregory Betancourt’s manuscript format article for the SFWA sets out the arithmetic, with 60 characters to a line divided by 6 characters per word for 10 words a line, and 25 lines to a page.
A dissertation set on a computer holds more than that, so I set pages in the format the AMBS style guide recommends and counted them. The guide asks for 12 point type, preferably Times New Roman or Arial, with 2.5 cm margins all round and 1.5 line or double spacing.
| Typeface and spacing | Lines per page | Words per page |
|---|---|---|
| Times New Roman, double | 25 | 332 |
| Times New Roman, 1.5 lines | 34 | 452 |
| Arial, double | 25 | 300 |
| Arial, 1.5 lines | 34 | 407 |
The lowest figure in the table is 20 per cent above the 250 rule, and the highest is 81 per cent above it.
My first run of this measurement was wrong. Times New Roman and Arial produced exactly the same count, which two typefaces of different widths cannot do. The file had named the fonts without declaring them, and the program had quietly set everything in its default typeface. With the fonts declared properly, Arial at double spacing came out 32 words a page below Times New Roman. The same page limit therefore allows about a tenth more text in Times New Roman than in Arial.
Bath’s guide assumes about 500 words to a page, which is more than any of the four pages I measured. The densest, Times New Roman at 1.5 line spacing, held 452. If you plan with 500 words a page, a 12,000 word dissertation looks like 24 pages, but in Times New Roman at double spacing it fills 36.
William Shunn reached a figure close to mine from a different direction. In a 2021 post on the old rule of thumb he answers a reader whose manuscript ran to 275 pages in standard manuscript format. The reader put it at 66,000 words, and the computer count came to 91,000. That is 331 words a page, against the 332 on my Times New Roman page at double spacing. In the old frame of 60 characters by 25 lines a page of real prose holds much less, about 234 words, as the article on the standard manuscript page measured.
Interim deadlines have lost their best-known study
Dissertation guides commonly recommend interim deadlines, and the AMBS timetable builds them in with its proposal and progress report. A study often cited in support of self-imposed deadlines was published by Dan Ariely and Klaus Wertenbroch in Psychological Science in 2002. The journal retracted it on 2 September 2026. The notice cites details brought to light by a replication, a lack of confidence in the underlying datasets and an investigation by the Data Colada blog that called the veracity of the data into question. Both authors agreed with the retraction (Retraction Notice, Psychological Science 37, 2026).
Interim deadlines may still help you. Without that study, though, the case for them rests on experience, and a schedule whose arithmetic you can check yourself is the firmer basis. The article on the writing goal calculator discusses the retraction in more detail.
Replace the starting values after three sessions
The 40 per cent share and the 0.6 buffer are starting values taken from other people’s data. After three writing sessions you have figures of your own, and they describe your dissertation better.
Write down two things after each session, the new words and the time you spent at the desk. The average tells you whether the plan holds. If your first three sessions average 350 words, a 12,000 word dissertation needs 35 sessions rather than 24, and at two a week that is 18 weeks of writing rather than 12. Finding that out in November leaves time to add a third day or to start the writing earlier.
Which unit to record depends on the phase. New words are the right measure for a first draft, while hours suit revision better, because good revision often makes a text shorter. The comparison of words, hours or pages goes through the cases one by one, and what a writing tracker measures explains what the record is useful for afterwards.
When a daily word count does not help
During data collection. Interviews, lab work and the wait for ethics approval produce no words, and a fortnight of them can pass without a single page. Plan them as separate weeks before the writing days start.
During revision. Cutting 2,000 words from an overlong draft is progress, although every counter shows it as a loss. Record revision as time, or your progress record will look like a reversal.
In the literature review. Here the cost lies in the reading. The words tend to arrive in a rush once the reading is done, so a steady daily figure fits this chapter badly.
For a PhD. Scribbr estimates that the writing alone can take around 18 months of a four year doctorate. Over that span a daily target says little, and chapter deadlines agreed with your supervisor carry the plan.
How many pages is 12,000 words?
About 36 pages in 12 point Times New Roman at double spacing, or 27 at 1.5 line spacing. Both figures assume pages filled with continuous text, so a real dissertation with headings, tables and figures will run a few pages longer.
Do footnotes and the bibliography count towards the word limit?
That depends on the handbook, and the two AMBS documents above already differ. The undergraduate style guide leaves footnotes, endnotes, references and appendices out of the count. The master’s handbook asks for a final word count that includes footnotes and endnotes, while references and appendices stay outside it. Warwick’s English department excludes footnotes, bibliography and appendices.
What happens if I go over the word limit?
The handbooks differ here too. The AMBS undergraduate handbook states that there is no penalty for a shorter or longer length. The AMBS master’s handbook uses a “guillotine”, which means markers need not read anything written more than 10 per cent past the limit. Warwick’s English guidance, last revised in 2021, allows a discretionary 10 per cent and deducts 5, 10 or 20 marks beyond it, depending on how far the work runs over.
Should I use 1.5 or double spacing?
Use whatever your handbook asks for. The AMBS style guide allows either, and the choice changes the page count considerably. In my measurement a Times New Roman page held 452 words at 1.5 spacing and 332 at double spacing, so the same text runs 36 per cent longer when it is double spaced.
How long does it take to write a 12,000 word dissertation?
The writing itself takes about 24 days at Bath’s pace of a page a day, plus two weeks or more for editing. The whole dissertation takes far longer. AMBS budgets 400 hours for it, and Scribbr notes that students may work on a dissertation alongside other classes for the whole final year or for the last six months.
Does the calculation work for a master's dissertation over the summer?
It does, with different inputs. The AMBS master’s dissertation has 8,000 words and a deadline in early September. If you can work on it every weekday from the start of June, that gives about 70 days, and at 40 per cent you get 28 writing days and fewer than 300 words a day. The daily figure is small because the dissertation is short and the summer is long, so the real risks lie in the data collection and in the dates of your supervision meetings.
What to do with this
Look up three numbers in your handbook, which are the word limit, the submission date and the credit value. Put the first two into the calculator together with the days you can really give the dissertation each week, and read the line with the buffer. If that figure looks uncomfortable now, you still have time to add a day or to start the writing sooner.
More conversions and benchmarks are collected under Word goals & metrics, and the research behind them under Data & studies. The article on 30 days of measuring shows how to turn a daily figure into a habit.
