How many words fit on a page in a printed book?

Between roughly 250 and 350, depending on the trim size and the type. A 5.25 × 8 inch novel holds about 270 words per page, a 5.5 × 8.5 about 285, and a 6 × 9 trade book about 330. Those are averages for continuous prose; dialogue, subheadings, lists and chapter openings all push the number down.

How many manuscript pages equal one book page?

About two. A manuscript page — twelve point type, double spaced — carries roughly 250 words, so a 90,000-word manuscript runs about 360 pages and comes out as a book of roughly 250 to 330 pages depending on the trim. The manuscript count is useful for editing and useless for printing.

Why does my page count keep changing as I format the book?

Because every typographic decision moves it: the typeface, the type size, the leading, the margins, how much space a chapter opening spends. The page count is an output of the typesetting, not an input, which is why the cover — whose spine width comes from that count — is built last.

Does the page count change my printing cost?

Yes. Print-on-demand pricing is a fixed charge plus a per-page charge, so a book that runs 350 pages costs measurably more per copy than the same words at 300. The count also decides which page-count limits apply to your ink and paper choice, and which inside margin band your book falls into.

How many pages will my book be?

Two numbers are called “the page count” and they are different animals.

The first is the manuscript’s: how many pages your Word file runs to at twelve point and double spacing. It exists so editors can say “cut ten pages” and is meaningless to a printer.

The second is the book’s: how many pages the typeset book runs to at the trim size you chose. That number decides the spine width on your cover, the printing cost per copy, and which of the platform’s page-count rules apply to you. It does not exist until the book is typeset, and it moves every time you change the type.

The arithmetic

A page of trade prose carries a fairly stable number of words, and the trims differ by how much page they give the text block:

Trim size	Roughly, words per page	An 80,000-word novel comes out at
5.25 × 8″	~270	~300 pages
5.5 × 8.5″	~285	~280 pages
6 × 9″	~330	~240 pages

Those are averages for continuous fiction at conventional type sizes. The same manuscript moves around them by tens of pages as the design changes — a typeface with a wide set, a size bumped from 11 to 11.5 points, or margins opened half an inch can each add five per cent or more.

What moves the count besides the words

Dialogue. A line of speech is short and gets its own paragraph, so a dialogue-heavy chapter carries far fewer words per page than the average. A novel that is mostly conversation can run twenty per cent longer than its word count suggests.

Chapter openings. Every chapter starts on a fresh page and throws away the bottom of the one before. Sixty short chapters spend more paper than twenty long ones carrying the same words — the cost of short chapters is covered in how long a chapter should be.

Subheadings, lists and tables. In nonfiction these eat vertical space the way dialogue eats horizontal patience. A 6 × 9 book dense with headings can drop to 280 words a page without anyone touching the type size.

Images. A figure occupies the height it needs plus its caption and its space above and below, none of which correlates with word count. Books with many images stop being estimable from the words at all.

Front and back matter. Half title, title page, copyright, contents, dedication — then acknowledgements, about the author, and the other books. Twenty-five to forty pages in a typical book, none of them carrying a word of the manuscript. They are counted, they are printed, and they are why an estimate taken purely from the prose comes in low.

A worked estimate

A 90,000-word novel, no images, thirty chapters, ordinary dialogue density:

At 6 × 9″: 90,000 ÷ 330 ≈ 273 pages of text, plus about 35 pages of front and back matter → roughly 310 pages.
At 5.5 × 8.5″: 90,000 ÷ 285 ≈ 316, plus 35 → roughly 350 pages.

Call it ±10 per cent. The real number arrives when the book is typeset, and it is worth knowing which decisions would move it: a larger trim, a slightly denser type setting, or twenty fewer chapters each pull the count down without touching the words.

Why the estimate matters before the typesetting

Three things downstream depend on the page count, and two of them have feedback loops.

The spine width comes from the page count and the paper, so the cover cannot be finished until the interior is — the sequence is in setting up a cover file.

The inside margin grows in bands as the page count grows, because a thick book curves more sharply into its binding — the bands are in formatting for KDP. Widening the gutter reflows the text, which can push the book into the next band, which asks for a wider gutter again. Any tool that sets margins has to converge on that, not apply the table once.

And the page-count limits for your ink and paper choice are absolute: cream paper tops out 52 pages earlier than white, and standard colour has the narrowest window of all. A 780-page estimate is legal on white paper and refused on cream, which is a far better thing to know before typesetting than after.

The short version

Words ÷ roughly 280 (5.5 × 8.5) or 330 (6 × 9), plus 25–40 pages of matter, is your estimate.
Dialogue, subheadings, images and chapter count all push the real number up.
The count is an output of the typesetting. Treat any number before then as a plan, not a fact.
The cover, the gutter, and the printing cost all wait on it, which is why they come last.

The page count is the one number in publishing that everybody wants early and nobody can honestly have. The estimate above is the honest version of it — good enough to pick a trim, plan a cover budget, and check you are not flirting with a page-count limit.

Nueel typesets the book as you work, so the real count is on screen from the first import rather than at the end — and the spine width, the margin band and the platform’s limits are re-measured against it every time the text moves.
