Undergraduate thesis usually requires between 8000- 10000 words, and graduate thesis requires between 2-30000 words. However, although the requirements of each university are different, they basically belong to this category.

Specifically, the introduction of the first chapter should not be too much, and it is best not to exceed 20-30% of the full text. For the main body of the paper, it should account for at least 50% of the whole paper. Finally, thank you, try not to try hard to code words just to make up the number of words. Usually just write a few hundred words.
