How many headings are recommended for academic papers?
5 heading levels
The number of headings recommended for academic papers would depend on what format the author follows. The APA style currently suggests at least five heading levels will do; however, the maximum number will depend on how long the paper is. Dividing the headings into sections and subsections will help clarify the topic to the reader. Unlike the APA, the MLA format does not require any minimum or maximum heading levels; however, it does require a running head placed on the upper left at the beginning page of the paper.
