How Many Words Are on a Page? The 250/500 Rule, Verified

A page holds about 500 words single-spaced or 250 words double-spaced – assuming 12-point Times New Roman, 1-inch margins, and letter-size paper. That is the convention stated by college library guides (Howard Community College), and it converges with two independent traditions: the typewriter-era manuscript rule of 250 words per page documented by William Shunn, and real printed novels, which average about 278 words per page (Brysbaert, 2019).

How Many Words Fit on a Single-Spaced vs Double-Spaced Page?

The standard answer is 500 single-spaced and 250 double-spaced. Howard Community College's library FAQ states the rule directly – "a good rule of thumb is 500 words for a single spaced page and 250 words for a double spaced page" – along with the caveat every mill site omits: the count "will vary depending on word length, font size and type, margin size, and spacing elements."

Double spacing is not arbitrary – it is required by the major academic styles. MLA format calls for a legible 12-point font, double spacing, and 1-inch margins on 8.5×11-inch paper. APA is even more explicit: "Double-space all parts of an APA Style paper, including the abstract; text; block quotations; table and figure numbers, titles, and notes; and reference list." So a "page" of academic writing is a double-spaced page, and 250 words is the working figure.

One catch before you trust either number: Microsoft Word's defaults don't match the rule's assumptions. Word ships with 1.15 line spacing and adds a blank line after every paragraph (Microsoft Support). A default Word page is neither single- nor double-spaced, and it holds noticeably fewer than 500 words. The 500/250 figures only apply after you manually set the classic academic format.

How Many Pages Is 500, 1,000, or 2,000 Words?

Divide your word count by 500 for single-spaced pages or by 250 for double-spaced pages. Every figure below is convention-based arithmetic on the standard academic format, not a measurement:

The same college guide works the conversion in the other direction: a 3–4 page double-spaced paper is roughly 750–1,000 words, and a 7-page double-spaced paper is about 1,750 words. It also notes that assignments increasingly specify length in words rather than pages "to ensure consistency across varying formatting choices" – which is exactly why these figures are estimates, not guarantees.

Where Does the 250-Words-Per-Page Rule Come From?

From typewriters. As manuscript-format authority William Shunn documents, pica typewriter type produced exactly 10 characters per inch, which on a page with 1-inch margins yields about 25 double-spaced lines – roughly 250 words. Editors paid by the word and needed a fast estimate; 250 words per manuscript page became the industry convention.

The manuscript format itself is still alive – Shunn's current spec calls for 12-point Times New Roman or Courier New, double-spaced, with one-inch margins all around. That is, the professional manuscript page and the academic paper page are the same page, which is why both traditions land on 250 words.

The estimation rule, however, is officially retired. Shunn declared it obsolete in 2021: now that every word processor counts words exactly, "the old rule of thumb for estimating word count" no longer serves a purpose. Use the computer's count – the 250 figure survives only as a page-length intuition.

How Many Words Per Page by Font and Font Size?

Honest answer: no verifiable standard exists for typed pages. The font-by-font tables circulating online (Arial vs Calibri vs Verdana) are copied between calculator sites with no stated methodology – one popular counter states the 500-word baseline and then contradicts it with its own calculator on the same page. We found no per-font figures worth publishing.

For printed books, one defensible dataset exists. The professional book designers behind Book Design Made Simple typeset the same 10,000 words at each trim size and type size and derived real capacity figures:

The ranges run from 12-point type (fewer words) down to 10-point type (more words). Two qualitative rules do hold: smaller type and larger pages fit more words, and monospaced fonts like Courier fit fewer words than proportional fonts like Times New Roman – that difference is built into the typewriter math above.

Do MLA, APA, or Chicago Define Words Per Page?

No – none of them. We checked the MLA Style Center's formatting guidance, Purdue OWL's MLA format page, APA's official paper-format pages, and the Chicago Manual of Style's public manuscript-preparation Q&A. Each defines fonts, spacing, and margins. None states a words-per-page figure.

So when a site claims "the MLA standard is 250 words per page," it is laundering a convention into an official rule. The 250 figure follows from the formatting the style guides require – it is not something they publish. The style bodies define the container; the word count is what happens to fit in it.

The practical consequence, as the college guides note, is that institutions increasingly assign word counts instead of page counts, precisely because page counts are formatting-dependent. If your assignment says pages, it implicitly assumes the classic double-spaced format – and if your title needs style-guide-correct capitalization to match, our guide to capitalization rules covers all four major styles.

How Many Words Are on a Page of a Printed Book?

Between 250 and 600, depending on the book. Three independent measurements bracket the range:

The same survey found fiction averages about 280 words per printed page versus roughly 233 for nonfiction – nonfiction's headings, lists, and white space eat capacity. For what those per-page figures add up to across a whole book – and how long that book takes to read at the average reading speed – see our companion piece on average book length.
