MLA Format Guide: Rules and Examples
A complete reference for MLA formatting rules with before-and-after examples.
What MLA formatting is for
MLA format, from the Modern Language Association, is the standard in literature, language, and the humanities. It covers everything from the title page to the reference list, and following it tells a reader exactly what to expect on every page.
The rules can feel fussy, but they exist for a reason. Consistent margins, fonts, and citation placement make a long paper easier to read and easier to grade. This guide pulls the rules you will use most often into one place.
Use it as a checklist while you write, then again before you submit. Most formatting points are lost not because the rules are hard, but because they are easy to miss on a final read.
The core of a MLA paper
- A header in the top right with your last name and the page number.
- One-inch margins and double spacing throughout the whole paper.
- A block of identifying information on the first page instead of a title page.
- In-text citations in author-page format, like (Smith 24).
- A Works Cited list at the end, alphabetical with a hanging indent.
MLA rules at a glance
| Element | What the rule asks for |
|---|---|
| Margins and spacing | One inch on all sides, double-spaced, with no extra space between paragraphs. |
| Font | A clear 12 point font, usually Times New Roman, with regular and italic styles available. |
| First page | Your name, instructor, course, and date stacked on the left, then a centered title. |
| Headings | No fixed heading levels; use italics and consistent placement to mark sections. |
| Works Cited | Alphabetical by author, with a hanging indent and containers used for nested sources. |
Before and after fixes
| Spot | Common mistake | Corrected version |
|---|---|---|
| In-text citation | (Smith says this on page 24.) | The effect appears early (Smith 24). |
| Works Cited entry | Smith, John. A Book. 2020. | Smith, John. A Book. Publisher, 2020. |
| Header | Page 1 (no name) | Smith 1 |
Set up a document in MLA
- 1Open a clean template
Start from a blank document or an official MLA template so you are not fighting inherited formatting from an old file.
- 2Set margins and spacing
Lock in one-inch margins and the line spacing the style asks for, then turn on a hanging indent for the reference list before you type any entries.
- 3Build the title page or header
Add the identifying details MLA wants on the first page, whether that is a full title page or a header block, and insert the running header if the style uses one.
- 4Write with citation placeholders
Insert your in-text citations as you draft using MLA's format, even if the reference entries are not finished yet, so nothing gets missed later.
- 5Finalize and proofread
Once the text is stable, build out the reference list in full and do a final pass focused only on formatting, since content edits tend to undo spacing and indentation.
A reader who knows MLA can skim a well-formatted paper and find any source in seconds. Bad formatting slows them down at exactly the moments you want them thinking about your ideas.
MLA ninth edition leans heavily on the container concept: describe the larger work a source sits inside, like a database or an anthology, before listing the smaller piece.
The reference list is where most MLA points are lost. Run it through the AI Humanizer Lab Citation Checker to catch missing fields, wrong italics, and punctuation slips before you hand the paper in.
