Hanging Indent Formatter
Paste your references, one per line, and see them set with a hanging indent — the first line flush left and every later line indented — as APA 7, MLA 9 and Chicago 18 require for a reference list, Works Cited or bibliography. Choose a 0.5 or 1 inch indent and single, 1.5 or double line spacing, then copy the result as rich text or HTML. Free, no sign-up, and nothing leaves your browser.
Hanging Indent Rules
APA 7th Edition
Use a 0.5-inch hanging indent for all reference list entries. Double-space the entire reference list. The first line of each entry is flush left, with subsequent lines indented.
MLA 9th Edition
Use a 0.5-inch hanging indent for all Works Cited entries. Double-space the entire list. Do not add extra space between entries.
Chicago Manual of Style
Use a hanging indent (typically 0.5 inches) for bibliography entries. Single-space within entries, and add a blank line between entries, or double-space throughout.
How to Use the Hanging Indent Formatter
- Paste your references. Put one entry on each line. A blank line is ignored, and every non-empty line is treated as one reference, so a reference that wraps over two lines should be joined into one first.
- Set the indent and spacing. The indent is 0.5 inch, which APA, MLA and Chicago all use, or 1 inch. Spacing is single, 1.5 or double; double is the default.
- Check the preview. Each entry appears with its first line at the margin and the following lines pushed in.
- Copy and paste. Copy as Rich Text puts formatted paragraphs on the clipboard for pasting into a word processor. Copy as HTML copies the HTML itself, for a web page or an editor that accepts markup.
What a Hanging Indent Is
In a hanging indent the first line of a paragraph starts at the left margin and every line after it is indented, the opposite of the first-line indent used for ordinary paragraphs. It lets the reader run an eye down the left edge and see where each entry begins, which is why author-name styles use it for the whole list.
| Style | Hanging indent | Spacing |
|---|---|---|
| APA 7 | 0.5 inch for every entry | double-spaced throughout, with no extra space between entries |
| MLA 9 | 0.5 inch for every entry | double-spaced throughout, with no extra space between entries |
| Chicago 18 | about 0.5 inch for every entry | single-spaced within an entry and a blank line between entries, or double-spaced throughout |
| Harvard | usually 0.5 inch; follow your university’s guide | varies by university |
| Vancouver, IEEE, AMA | none — numbered lists | varies |
APA, MLA and Chicago rules from their manuals; the tool’s own notes under the preview repeat the same three. Numbered styles list references by number, not with a hanging indent.
Worked Example
With the tool’s two sample lines — Smith, J. (2024) and Johnson, A. (2023) — and the defaults of 0.5 inch and double spacing, each reference becomes one paragraph styled padding-left: 0.5in; text-indent: -0.5in; line-height: 2.8, with 0.3em of space after it. The padding moves the whole paragraph in half an inch, and the negative text indent pulls the first line back out to the margin, which is exactly what a hanging indent is. Line heights of 1.4, 2.1 and 2.8 stand for single, 1.5 and double spacing in the preview and the copied HTML.
Getting It Into Your Document
- Paste, then check. Programs differ in how much of the pasted formatting they keep. After pasting, select the list and confirm the hanging indent in the paragraph settings.
- Set it in the program if needed. In Word choose Paragraph, then under Special choose Hanging at 0.5″. In Google Docs use Format, Align & indent, Indentation options, Special indent: Hanging.
- Alphabetize first. The formatter keeps your order. Sort an author-date or MLA list with the Bibliography Alphabetizer before you indent it.
- Do not use spaces or the Tab key. Manual spacing breaks as soon as the text reflows. A real hanging indent is a paragraph setting.
Which Tool Do You Need?
- Indent a finished reference list: this page.
- Put the list in A–Z order: Bibliography Alphabetizer. To sort any other list of lines, use Sort Lines.
- Indent a long quotation from the left instead: Block Quote Formatter.
- Check the entries themselves: the APA, MLA and Chicago citation checkers.
- Export a bibliography already indented: see how to export a bibliography to Word or Google Docs.
Frequently Asked Questions
- What is a hanging indent?
- A paragraph layout in which the first line starts at the left margin and every following line is indented. Reference lists in APA, MLA and Chicago use it so each entry’s first word, usually the author’s surname, stands out at the margin.
- How much should a hanging indent be?
- 0.5 inch (1.27 cm) from the left margin in APA 7, MLA 9 and Chicago. The tool also offers 1 inch for departmental templates that ask for it; use the size your instructor or journal specifies.
- How do I make a hanging indent in Word or Google Docs?
- In Word, select the list, open Paragraph, and under Special choose Hanging with a value of 0.5″. In Google Docs, use Format, Align & indent, Indentation options, and set Special indent to Hanging at 0.5″. This tool gives you the same layout to paste, so you can check it against the paragraph settings.
- Do all citation styles require a hanging indent?
- APA, MLA and Chicago do, and so do most Harvard guides. Numbered styles such as Vancouver, IEEE and AMA list references by number and do not use one in the same way.
- Should the list also be double-spaced?
- APA and MLA double-space the whole list with no extra space between entries. Chicago single-spaces within entries and puts a blank line between them, or double-spaces throughout where an instructor asks for it. Choose the spacing in the tool to match.
- Why did my indentation disappear after pasting?
- The program you pasted into dropped the formatting, which some editors and form fields do. Paste into a word processor, or set the hanging indent in the paragraph settings after pasting plain text.
- Is my reference list uploaded anywhere?
- No. The formatting runs in your browser; nothing you paste is sent to a server or stored.
