How long should a research paper introduction be?

Typically 10-15% of your paper. For a 10-page paper, aim for 1-1.5 pages. It should be long enough to provide context without overwhelming the reader.

Should I write the introduction first or last?

Many successful researchers write the introduction last — after completing the body. This ensures the introduction accurately previews the paper's content.

Do I need citations in the introduction?

Yes. Background information and claims about existing research should be cited. The introduction typically includes 3-5 citations.
