You’ve finished compiling your reference list, but something looks off — every entry needs a hanging indent, and manually pressing Tab for each line is going to take forever. Worse, if you add or remove a citation later, your formatting will break.

A hanging indent is required by APA, MLA, and Chicago for every entry in your reference list, works cited list, or bibliography. The first line is flush left, and all subsequent lines are indented 0.5 inches. This guide shows you three ways to create a hanging indent in Microsoft Word, plus the correct settings for each citation style.

What Is a Hanging Indent?

A hanging indent (also called a negative indent) is a paragraph format where the first line starts at the left margin and every subsequent line is indented. In APA 7th edition, MLA 9th edition, and Chicago 17th edition, the indent depth is 0.5 inches (1.27 cm). This format makes it easy for readers to scan down a reference list and quickly find the author they’re looking for.

Method 1: Paragraph Dialog Box (Recommended)

This is the most reliable method and works in all modern versions of Word.

1. Select the citation entries you want to format.
2. Go to the Home tab and click the small arrow in the bottom-right corner of the Paragraph group to open the dialog box.
3. In the Indentation section, open the Special dropdown and select Hanging.
4. Ensure the By field is set to 0.5″.
5. Click OK.

Alternatively, right-click the selected text and choose Paragraph to access the same settings.

Method 2: Keyboard Shortcut (Fastest)

Highlight your citations and press Ctrl + T on Windows or Cmd + T on Mac. This automatically applies the default 0.5-inch hanging indent. To remove it, press Ctrl + Shift + T.

Method 3: The Ruler Tool (Visual)

1. Go to the View tab and check the Ruler box to display the ruler above your document.
2. Select the citations you want to format.
3. On the ruler, you will see two triangular markers on the left side. The top triangle controls the first line indent. The bottom triangle controls the hanging indent.
4. Drag the bottom triangle to the 0.5-inch mark on the ruler.
5. Ensure the top triangle remains at the 0-inch mark (left margin).

Spacing Requirements by Style

Style	Indent Depth	Line Spacing	Extra Space Between Entries
APA 7th	0.5″	Double-spaced	No
MLA 9th	0.5″	Double-spaced	No
Chicago 17th	0.5″	Single-spaced within entries	Yes (one blank line between entries)

Common Hanging Indent Mistakes

• Using the Tab key manually — Manually tabbing each line creates formatting that breaks when you edit the text. Always use the paragraph settings or keyboard shortcut.
• Wrong indent depth — APA, MLA, and Chicago all use 0.5 inches. Some older guides used different depths; always confirm the current standard.
• Incorrect spacing for Chicago — Chicago requires single-spaced entries with blank lines between them. APA and MLA use double spacing throughout.
• Forgetting to apply to the entire list — Select all entries before applying the hanging indent. Applying it entry by entry is time-consuming and inconsistent.

Automate Your Reference List Formatting

While hanging indents are easy to set up manually, the rest of your reference list — author formatting, title capitalization, DOI placement — is much more complex. Formatly handles all of it automatically.
