1. Depending on the paper type. Generally speaking, different types of papers need different words. For example, the master's thesis is generally about 30 thousand words, taking the introduction as an example.

Generally speaking, it is estimated to be about 6000-8000 words, the research background is about 800 words, the purpose and significance are about 500-600 words, the research method is about 300 words, the theoretical summary part is about 2000-3000 words, the main research content part is about 600 words, and the latest research trends at home and abroad are about 2000 words.

2. Ask the school for confirmation. Different schools have different requirements for the number of words in papers. Some schools require about 10000 words for undergraduate thesis, while others require about 15000 words.

According to different word requirements, the number of words in each part of the paper should be increased or decreased appropriately, such as undergraduate thesis 1 000 words, general statement 1 000 words (including 500 words of literature review), current situation and problem description 2000 words, problem analysis 2000 words, countermeasure suggestion 3000 words and conclusion 500-800 words.

3. Construction according to the outline. Because the outline structure of the paper is conceived in consideration of the details of each part, the parts with more chapters in the outline of the paper should generally be elaborated in detail.

But in general, we should follow the layout strategy mentioned above, don't write more where we are interested and grasp well, and write less when our theoretical knowledge is weak, so as not to cause structural imbalance.
