In APA 7th edition, headings organise content within the body of a paper using five formatted levels, while section labels are standardised titles, such as Abstract or References, that mark whole sections and aren’t counted as headings.
Section labels apply to specific parts: the title itself, the abstract, the reference list, footnotes, and appendices, and these are formatted consistently rather than styled like a numbered heading level.
Headings, by contrast, appear within the main body and can go up to five levels, ranging from a centred, bold title at level one to a shorter, indented, bold italic heading at level five.
Subheadings in APA should stay at the same level for sections of equal importance; skipping a level, such as jumping from level one straight to level three, breaks the document’s logical hierarchy.
Getting this distinction right matters most in dissertations and long reports, where our APA style guide breaks down each heading level with formatting examples.
If you’d rather have a specialist format the whole document correctly, our referencing and citation support service checks headings, section labels, and citations together.
