This is a question that I get asked a lot. How many pages should a dissertation conclusion be? The answer to this question depends on a few factors. The first factor is the length of the dissertation. A dissertation that is 50 pages long will obviously have a different conclusion than one that is 200 pages long. The second factor is the type of dissertation. A qualitative dissertation will likely have a different conclusion than a quantitative dissertation. The third factor is the style of writing. Some people write very concisely while others are more verbose.
Assuming that you are writing a quantitative dissertation that is 100 pages long, your conclusion should be about 5-7 pages long. If you are writing a qualitative dissertation that is 200 pages long, your conclusion should be about 10-15 pages long. If you are writing in a more concise style, your conclusion could be shorter. Ultimately, the length of your conclusion should be determined by the length of your dissertation and the style of writing that you are using.
