Hanging Indent
A paragraph format where the first line is flush left and subsequent lines are indented. Required for reference lists in APA, MLA, and most citation styles.
Why it matters
Hanging indents make reference lists easier to scan by visually separating each entry and highlighting the first element, usually the author's last name. This formatting is not optional in most citation styles; it is a strict requirement that graders and journal editors check for. Missing hanging indents are one of the most common formatting errors in student papers.
How to use
In Microsoft Word, select your reference entries, go to Paragraph settings, and set "Special" indentation to "Hanging" with a 0.5-inch indent. In Google Docs, use Format > Align & indent > Indentation options and set the "Special indent" to "Hanging." Avoid manually pressing Tab or Enter to create the indent, as this creates inconsistent spacing.
In academic writing
Hanging indents are required by APA, MLA, Chicago, Harvard, and virtually every other major citation style for the reference list or bibliography. They are a standard formatting element that students must learn early in their academic career. Word processors and citation managers can apply hanging indents automatically, saving significant time when formatting a long reference list.
Common mistakes
- •Using manual tabs or spaces to create the indent instead of the word processor's hanging indent feature, which breaks when the font or margin changes.
- •Applying the hanging indent to the entire paper instead of only the reference list.
- •Forgetting to apply the hanging indent entirely — this is one of the easiest points to lose on formatting.
