How long is a dissertation?

There is no minimum or maximum page requirement when it comes to the length of a dissertation. However, on average, a dissertation is between 100 and 200 pages in length.

There are a number of factors that can go into the length of a dissertation. One of these factors is the industry. A dissertation in a mathematics field may not need to be as lengthy as one in a health sciences or human services field. The topic of the dissertation can also play a role, as some topics require more research and data to completely make a point and argue that point.
