1. research objectives and questions: first, make clear your research objectives and questions, which will determine how much information you need to provide to answer these questions. If the purpose of your research is to solve a specific problem, then your paper should contain enough information to support your conclusion.

2. Target audience: Know who your target audience is and how familiar they are with your research topic. If your target audience is professionals, then you should use more formal language and more detailed explanations. If your target audience is non-professionals, you should try to use simple and clear language and avoid using overly complicated or professional terms.

3. Literature review: refer to relevant academic literature to see how other researchers organize their papers. This can help you understand how long a suitable text should be.

4. Requirements for journals or conferences: Different journals or conferences may have different word requirements. Make sure you have read and understood these requirements.

5. Importance of content: For very important or key content, more space may be needed for explanation and discussion. For less important or critical content, it may be necessary to shorten the length.

6. Revise and edit: It is also a good idea to spend time revising and editing after writing the first draft. Through this process, you may find that you need to add or delete some words.

Generally speaking, determining the text length of academic papers needs to balance the integrity, readability and conciseness of information.
