The number of words in a master's thesis is between 30,000 and 50,000. The master's thesis only contains the number of words in the text, not including abstract, table of contents, thanks, references, appendices, etc. The specific number of words needs to refer to the regulations of the school and major. For example, after some schools require the number of words in the opening report, the number of words in the text remains at 30,000 words; Some schools also require the number of words to be between 60 and 80 pages; Other schools require the full text to be between 30,000 and 50,000 words, including 30,000 words for literature and more for science. Before writing a thesis, graduate students need to know the specific vocabulary requirements of their school and major in order to formulate a reasonable thesis framework and scheme.
