What your thesis is worth in hours, and how to find out
Anywhere in the European Higher Education Area, your thesis carries a credit weight, and credits are defined in hours. The European Commission's ECTS Users' Guide, adopted by education ministers in 2015 and still the official version, sets the conversion: "60 ECTS credits are allocated to the learning outcomes and associated workload of a full-time academic year", and "workload ranges from 1,500 to 1,800 hours for an academic year, which means that one credit corresponds to 25 to 30 hours of work."
Multiply that out and the shape of the project appears.
| Thesis | Typical credits | Hours at 25 to 30 per credit | Over a six-month registration |
|---|---|---|---|
| Bachelor | 10 to 15 ECTS | 250 to 450 | 10 to 17 hours a week |
| Master | 30 ECTS | 750 to 900 | 29 to 35 hours a week |
The hours column is arithmetic on the Commission's own range, not a separate claim. Universities that publish both numbers land inside it: the University of Twente states that "A Bachelor's thesis is carried out in the form of a 15 EC (420 hours) research project", which works out at 28 hours per credit. The credit weights are real too, and easy to check for your own programme. KTH prices its bachelor degree project at "15.0 credits" and its master degree project at "30.0 credits". Freie Universität Berlin's computer science examination regulations put it in one clause: six months, 30 credits.
That right-hand column is the fact worth carrying away. A 30-credit master's thesis is a full-time job for six months. If you are also taking courses, working, or planning to start in month four, the arithmetic has already told you how that ends.
A six-month master's thesis, with the months marked
The clock usually starts before you think it does. Bonn's arts faculty allows "A maximum period of six months ... from the issuing of the topic (date of signature of the first examiner)", and Berlin's regulations start counting from the day the examination board issues the topic. Nothing you read before that date is on the clock. Nothing you read after it is off it.
The month split below is ours, allocating the verified 750 to 900 hours across a registration period that many European regulations set at six months. Your department's own deadline document overrides every row of it.
| Month | What exists at the end of it | Rough hours | What goes wrong here |
|---|---|---|---|
| Before the clock | A supervisor and a topic they have agreed to | Unpaid, and worth the most | Waiting for a perfect topic. A good supervisor and a decent question beats the reverse |
| Month 1 | A proposal: question, method, scope, and a schedule your supervisor signed off | 120 | A question so broad no six-month project could answer it |
| Month 2 | The literature read, mapped by theme, notes tied to specific claims with page numbers | 140 | Reading with no stopping rule. Set one on day one and write while you read |
| Month 3 | Methodology fixed and written, data collection or the build under way | 140 | Changing the method in month four. This is the chapter examiners read closest |
| Month 4 | Results exist, even ugly ones | 140 | Discovering the data cannot answer the question, with no time to change either |
| Month 5 | A complete draft in your supervisor's hands, introduction included | 140 | Sending chapters one at a time. A supervisor reads a whole argument differently |
| Month 6 | Revision, reference audit, formatting, submission | 120 | The reference audit. Hundreds of citations gathered over five months, checked in one panicked evening |
A bachelor thesis is the same shape at roughly half the hours, and often on a shorter clock: Bonn allows three months for its bachelor theses, RWTH Aachen's mechanical engineering faculty states 8 to 10 weeks for a bachelor project and 18 to 22 weeks for a master's, and Trier sets three or four months for bachelor work and six for master's with extensions capped at six weeks. TU Munich declines to give a number at all and says the period "is specified in the FPSO (Departmental Study and Examination Regulations) of your degree program", which is the honest general answer: this is a departmental fact, not a national one.
Nobody will give you a word count, and here is why
The length question has no cross-institution answer, because length is set per department in a document with a name. What that document says varies more than students expect:
- Eindhoven University of Technology, for a computer science master's thesis: "A typical thesis length is 40-60 pages."
- LSE, for an undergraduate economic history dissertation: "The dissertation must not exceed 10,000 words in length."
- Cambridge geography undergraduates "submit a 10,000-word dissertation on a subject of their choice", and Oxford history guidance warns that "you only have 12000 words and referencing counts within that limit".
- TU Chemnitz refuses the question outright for computer engineering: "The length of a bachelor thesis cannot be restricted to a particular number of pages", then describes anything under 30 pages as scarce and anything over 120 as hardly justifiable.
Find your own department's version in week one. It is normally the examination regulations or a faculty handbook, it will also tell you the deadline, the submission format and whether references count inside the limit, and every one of those is a decision you would otherwise make wrong and late.
The four guides, and when in the timeline to read them
- Before the clock starts, and month 1. How to write a research proposal is the template and the worked example, plus the mistakes that get proposals sent back.
- The whole run. How to write a bachelor thesis walks topic to defense and marks what changes at master's level.
- Month 3. How to write a methodology takes the chapter apart component by component, which matters because it is the one an examiner tests for reproducibility.
- Before you let a tool near any of it. Can AI write my thesis covers what AI genuinely does well across hundreds of citations and what stays yours in a room where you have to defend it.
One habit does more for month 6 than anything else on this page: check each source when you add it, not at the end. A thesis carries hundreds of references gathered over half a year, and the difference between checking as you go and auditing them all in one evening is the difference between an hour of work and a weekend of it.
