Harvard Format Guide: Rules and Examples
A complete reference for Harvard formatting rules with before-and-after examples.
What Harvard formatting is for
Harvard format, from the Harvard author-date system, is the standard in business, the sciences, and many UK and Australian universities. 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 Harvard paper
- In-text citations in author-date format inside brackets, like (Smith 2023).
- A reference list at the end, alphabetical by author surname.
- One-inch margins and double or one-and-a-half line spacing.
- A clear title page with the title, your name, and your institution.
- Italics for the titles of larger works like books and journals.
Harvard rules at a glance
| Element | What the rule asks for |
|---|---|
| Margins and spacing | One inch or equivalent, with spacing set by your department, usually 1.5 or double. |
| Font | A standard 12 point font such as Times New Roman or Arial. |
| In-text citations | Author and year in brackets, with a page number for direct quotes, like (Smith 2023, p. 24). |
| Reference list | Alphabetical, with a hanging indent and full publishing details for each source. |
| Consistency | Because there is no single manual, match your school's house style exactly. |
Before and after fixes
| Spot | Common mistake | Corrected version |
|---|---|---|
| In-text citation | (Smith 2023 says...) | Earlier work confirms this (Smith 2023). |
| Reference entry | Smith, J. (2023) A Book. | Smith, J. (2023) A book. London: Big Press. |
| Direct quote | "It worked." (Smith) | "It worked" (Smith 2023, p. 24). |
Set up a document in Harvard
- 1Open a clean template
Start from a blank document or an official Harvard 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 Harvard 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 Harvard'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 Harvard 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.
Harvard has no official manual, so two universities can format the same source differently. Always follow the guide your department hands out.
The reference list is where most Harvard 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.
