Hanging Indents for APA References: The Two-Click Fix in Word and Google Docs, and Why the Tab Key Breaks It

Open your reference list and look at any entry that spans two lines. If the second line sits flush against the margin instead of tucked in half an inch, you're missing the one formatting rule graders check first, and almost every draft has at least one entry where it slipped.

An APA hanging indent is the paragraph setting APA 7 requires for every entry on a reference list, and for every entry in an annotated bibliography: the first line starts flush left, and each line after it indents 0.5 inches (APA 7, Sections 2.12 and 9.43). It's a paragraph-formatting setting, not something you build with the Tab key or the space bar, and once it's set correctly it survives every source you add, delete, or reorder for the rest of the paper.

What the APA hanging indent is actually doing

The reference list has its own rules before the indent even comes into play: it sits on its own page titled References, centered and bold, entries alphabetized by the first author's last name, the whole thing double-spaced with no extra space between entries. The hanging indent is what makes that alphabetized list scannable. With the first line flush left, your eye can run straight down the page by author name. The wrapped lines sit visually below it, so a two-line entry doesn't get mistaken for two separate sources.

This is the same setup our complete guide to APA 7th edition format walks through for the whole paper, but the reference list is where it earns its keep. Get the indent wrong here and the page reads as a wall of text instead of a list.

The wrong way: Tab, the space bar, or Enter and Tab

The mistake: pressing Tab at the start of the second line of an entry, hitting the space bar until it looks indented, or pressing Enter and then Tab to fake the wrap.

All three look correct on the page you're staring at right now, and almost everyone tries one of them before finding out there's a paragraph setting built for exactly this. Tab presses, space bar taps, and Enter-then-Tab are manual keystrokes sitting inside the text of the entry, and that's exactly why they don't hold up as a real hanging indent.

Why it matters: the moment that entry reflows, because you added a source above it, deleted one, switched fonts, or the page break lands somewhere new, the manual tab or spaces move with the text instead of staying anchored to the paragraph. You end up with an indent that's a quarter-inch too far, a wrapped line with no indent at all, or a stray tab sitting mid-sentence. A grader who has seen this fifty times spots it in the time it takes to scroll past the page.

The fix: set the indent as a paragraph property, once, for the whole reference list. It then travels with the paragraph automatically, no matter what you add above or below it. Select the whole list before you set it, not just one entry at a time, so every source lines up the same way from the start.

How to set an APA hanging indent in Word

Select every entry in your reference list, then open the Paragraph dialog: Home tab, click the small arrow in the bottom-right corner of the Paragraph group. Under Indentation, set Special to Hanging and By to 0.5". Click OK, and every selected entry indents its wrapped lines automatically.

You can do the same thing with the ruler if you'd rather drag it: leave the upper, first-line marker sitting at the margin, and drag the lower triangle, the hanging-indent marker, down to the 0.5" mark. Either method sets the same paragraph property. The dialog box is just harder to get wrong with a mouse.

How to set it in Google Docs

Select the entries, then go to Format → Align & indent → Indentation options. Under Special indent, choose Hanging, set it to 0.5, and click Apply. Google Docs applies it the same way Word does: as a paragraph property attached to those entries, not a manual keystroke sitting in the text. If you started the paper in Word and moved it into Docs, or the other way around, reapply the setting after the move rather than assuming it carried over cleanly.

Why it breaks anyway

Even after you set it correctly, a hanging indent can come loose in a couple of specific ways. Pasting a citation in from a citation generator or another document often drags that source's own paragraph formatting along with it, which can override the hanging indent you already applied to the list. Reformat the pasted entry, or paste as plain text and reapply the indent to the whole list afterward. And if you ever go back and add a Tab keystroke inside an entry "just to nudge it," you've reintroduced the exact problem the paragraph setting was there to prevent. Trust the dialog box, not your eye, and don't hand-adjust individual entries.

This is one entry in a longer pattern of small formatting habits that cost real points. If you want the rest of them, our rundown of 10 APA formatting mistakes that cost the most points covers it, and if you're not even sure whether your assignment wants a plain reference list or an annotated one, the difference between a reference list and a bibliography is worth a read before you format either one.

Do this in one step instead

You can set the hanging indent by hand in under a minute with the steps above, and once it's set right, it stays right. This is exactly the kind of detail we built StyleMyPaper to catch, so you're not stuck re-checking it every time you add a source. Upload your draft and it applies the hanging indent, along with the rest of the reference-list formatting, for you. See how the APA formatting tool handles it.
