You’ve written a well-organized paper with clear section breaks, but your professor returned it with a note: “Heading levels are incorrect.” You’re not alone — APA heading hierarchy is one of the most commonly misunderstood formatting rules.

APA 7th edition defines a strict five-level heading system. Using it correctly makes your paper easier to read and signals to your instructor that you understand academic formatting standards. This guide breaks down each level with examples, shows you how to use them in the right order, and explains how to automate the process so you never have to think about heading formatting again.

The Five APA Heading Levels

Level	Format	Alignment	Text Starts
1	Bold, Title Case	Centered	New paragraph
2	Bold, Title Case	Flush Left	New paragraph
3	Bold Italic, Title Case	Flush Left	New paragraph
4	Bold, Title Case, Period	Indented 0.5″	Same line
5	Bold Italic, Title Case, Period	Indented 0.5″	Same line

How to Use Heading Levels Correctly

The most important rule: never skip a heading level. If you need a subheading under a Level 1 heading, use Level 2. If you need a subheading under Level 2, use Level 3. Do not jump from Level 1 directly to Level 3.

Example Structure

Here is how a properly structured APA paper might look:

• Method (Level 1, centered)
• Participants (Level 2, flush left)
• Recruitment Criteria (Level 3, flush left italic)
• Materials (Level 2, flush left)
• Procedure (Level 2, flush left)
• Results (Level 1, centered)
• Discussion (Level 1, centered)

Notice that Level 4 and Level 5 headings are rarely needed in most student papers. They exist for complex, multi-layered documents such as dissertations or systematic reviews.

Title Case Capitalization

All APA headings use title case capitalization. This means capitalizing the first word, the last word, and all major words (nouns, pronouns, verbs, adjectives, adverbs). Do not capitalize short conjunctions (and, but, or), articles (a, an, the), or prepositions (of, in, to, for) unless they are the first or last word.

What About the Introduction?

In APA 7th edition, the introduction does not receive a heading. The title of your paper at the top of the first page serves as the de facto Level 1 heading. Begin your introduction text directly after the title without an additional heading.

Common Heading Mistakes

• Skipping levels — Going from Level 1 to Level 3 is incorrect. Always use the next level in sequence.
• Using bold for Level 4 and 5 — Level 4 is bold (not italic), Level 5 is bold italic. These are easy to confuse.
• Adding extra spacing — Do not add extra blank lines above or below headings. The entire paper should be consistently double-spaced.
• Indenting Level 1–3 headings — Only Level 4 and 5 headings are indented. Levels 1–3 are flush left (Level 1 is centered).
• Using numbered headings — APA does not use numbers or letters to label headings. The formatting itself communicates the level.

Automating APA Headings

Manually formatting each heading in a long paper is tedious and error-prone. The easiest way to ensure consistent APA heading formatting is to use a tool that applies the rules automatically. Formatly handles heading levels, capitalization, spacing, and indentation in seconds — no more scanning the Publication Manual for every section break.
