As per Section 2.4 of the APA Publication Manual, 7th edition, the title of a research paper should summarize the main idea in a succinct manner. While there is no prescribed title length in APA style, authors are advised to keep their titles brief and focused. The manual also provides examples between effective and ineffective titles, including “fluff” words that can be cut from titles and substantive information that should be included in a title to make it relevant to the reader(s).
