APA 7: Headings

There are five levels of heading in APA Style. Level 1 is the highest or main level of heading, Level 2 is a subheading of Level 1, Level 3 is a subheading of Level 2, and so on through Levels 4 and 5.

The number of headings to use in a paper depends on the length and complexity of the work.

• If only one level of heading is needed, use Level 1.
• If two levels of heading are needed, use Levels 1 and 2.
• If three levels of heading are needed, use Levels 1, 2, and 3 (and so on).
