APA Headings and Subheadings: All Five Levels Explained
APA headings organize papers into clear sections. Learn all five levels, formatting rules, and examples for APA 7 student writing.
Why APA Headings Make Student Papers Easier to Read
APA headings give your paper a clear structure, especially when your assignment includes several sections or complex ideas. Instead of making readers guess where one topic ends and another begins, headings show the order of your argument. APA headings follow five possible levels, but most student papers only need the first one or two. Knowing how the levels work helps you format research papers, literature reviews, lab reports, and longer academic assignments with confidence.
The Five APA Heading Levels
APA 7th edition uses five heading levels. Each level has a different format and shows a different depth in your paper.
Level 1 Heading
Use Level 1 for the major sections of your paper.
Text begins as a new paragraph.
Example:
This section summarizes previous research related to the topic.
Level 2 Heading
Use Level 2 for subsections within a Level 1 section.
Text begins as a new paragraph.
Example:
Researchers have examined several factors that influence academic performance.
Level 3 Heading
Use Level 3 when a Level 2 section needs to be divided into smaller topics.
Text begins as a new paragraph.
Example:
Text begins as a new paragraph below the heading.
Level 4 Heading
Use Level 4 for more detailed subsections beneath a Level 3 heading.
Example:
Level 5 Heading
Use Level 5 only when another level of organization is necessary under Level 4.
Example:
How Many APA Headings Should You Use?
Use only the number of heading levels your paper actually needs. A short student essay may only need Level 1 headings, while a longer research paper may use Levels 1 and 2. More complex papers, such as theses or detailed lab reports, may need Levels 3, 4, or 5.
Do not skip levels. If you use a Level 3 heading, it should appear under a Level 2 heading, not directly under Level 1.
Common APA Heading Mistakes
Avoid numbering headings unless your instructor specifically asks for numbered sections. Do not change font size, color, or style just to make headings stand out. Keep title case consistent, and make sure each heading accurately describes the section that follows.
APA headings improve the structure and readability of your paper, but proper citations are just as important for academic writing.
