How Many Words Per Page in a Book? Measure Your Layout, Then Divide
There is no single number of words per page in a book. It is set by the layout: trim size, typeface, font size, line spacing (leading), margins, and how often the text is broken by chapter openings, headings and images. The reliable way to get your figure is to build some of your book in its real layout, count the words and the pages, and divide. Two finished books we built on one template came out at 206 and 226 words per page, a 9% spread on the same template.
Once you have that number, page count is one division.
The formula
- Words per page = words in the built file / pages in the built file
- Estimated pages = word count / words per page, rounded up
- Words needed for a target length = target pages x words per page
The first line is the measurement. The other two only work if the first was taken on the same layout you will print.
Two books, measured
Both books below were built on one template: 6 x 9 inch trim, 11-point Georgia on 15-point leading, a 0.875 inch inside margin and 0.75 inch on the other three sides. That gives a 4.375 inch text block and room for 36 lines of body text on a full page. Words and images were counted in the source; pages were counted in the built PDF.
| Book (same template) | Words | Images | Pages built | Words per page |
|---|---|---|---|---|
| Ceramic Button & Jewelry | 24,627 | 14 | 109 | 226 |
| Curing and Charcuterie | 34,062 | 28 | 165 | 206 |
Note what this ratio is: total words divided by total pages. It already includes chapter openings, short last pages, headings and the space the images take. That is why it is lower than what a single full page of running text holds, and why it is the ratio worth carrying around.
Page count from word count
Here is the second formula applied at a few illustrative ratios (200, 250, 300, 350 words per page). None of these is “the standard”. They show how far the answer moves when the layout changes:
| Words | at 200 wpp | at 250 wpp | at 300 wpp | at 350 wpp |
|---|---|---|---|---|
| 40,000 | 200 | 160 | 134 | 115 |
| 60,000 | 300 | 240 | 200 | 172 |
| 80,000 | 400 | 320 | 267 | 229 |
| 100,000 | 500 | 400 | 334 | 286 |
The same 100,000 words make anywhere from 286 pages (at 350 words per page) to 500 pages (at 200). That gap is the reason a calculator that does not ask about your layout cannot give you a page count.
Words needed for a target page count
Working the other way, this is the planning table from the worksheet below, at 200, 215, 230 words per page, the range that brackets the two measured books:
| Target pages | at 200 wpp | at 215 wpp | at 230 wpp |
|---|---|---|---|
| 120 | 24,000 | 25,800 | 27,600 |
| 150 | 30,000 | 32,250 | 34,500 |
| 175 | 35,000 | 37,625 | 40,250 |
| 200 | 40,000 | 43,000 | 46,000 |
| 225 | 45,000 | 48,375 | 51,750 |
At 175 pages, the low column says 35,000 words and the high column says 40,250. That is 5,250 words of difference from a ratio that only moved from 200 to 230. Read the column that matches your own measured ratio, not the middle one.
How many words per page in a novel
The same answer applies: it depends on the novel’s layout. If you want the figure for a printed novel you are using as a model, measure it:
- Open to a full page of running text, not a chapter opening.
- Count the lines on the page.
- Count the words in ten lines and divide by ten for words per line.
- Multiply words per line by lines per page.
As an illustration: 30 lines, 102 words in ten lines, gives 10.2 words per line and about 306 words on a full page. At that rate, 60,000 words would fill about 197 full pages of text.
That is the full-page ceiling for that layout. The whole-book figure will be lower, because chapter openings, scene breaks and short last pages hold fewer words. Use the full-page count as an upper bound and expect the built book to run longer.
Chapter openings and blank pages
If each chapter starts on a new page, the last page of the chapter before it is only partly filled. That costs somewhere between almost nothing and almost a full page per chapter, depending on where the text happens to end.
Take an illustrative 60,000 words at 250 words per page: that is 240 pages of text. With 20 chapters each starting on a new page, the book lands somewhere from 240 up to just under 260 pages. If each chapter must start on a right-hand page, a blank left-hand page can be added before some of them, and the ceiling rises to just under 280. Front matter (title page, copyright, contents) and back matter add pages on top of that.
The measured ratios above already include their own chapter breaks, which is another reason to measure a whole built file rather than one page.
Changing the layout changes the answer
You can rough out how a layout change moves the number before you rebuild, as long as you treat it as an estimate:
- Smaller trim. Keep the same font, leading and margins but move from 6 x 9 to 5.5 x 8.5. The text block narrows to 3.875 inches and a full page drops to 33 lines. Together that is about 19% fewer words on a full page, which would move the measured 206-226 to roughly 168-183.
- Tighter leading. On the original trim, going from 15-point to 14-point leading fits 38 lines instead of 36, about 6% more words on a full page.
Both are geometry on full pages of text. After any change like this, build the file and measure again.
Why there is no formula with an image term
It is tempting to fit a formula from the two books: some words per page, plus some page cost per image. Two books give two equations in two unknowns, so the fit always produces an answer. Here it produces 287 words per page and 1.65 pages per image. An image in these books does not take more than a page and a half. The fit is absorbing every other difference between the two books (how chapters broke, how long the headings and lists were) and calling it “images”. It is internally consistent and wrong.
The same problem applies to published word-count tables that do not state a layout. The worksheet below quotes one that pairs 18,000-25,000 words with 180-220 pages for craft non-fiction, which implies only 100-114 words per page. On the measured template, 25,000 words built to about 111-122 pages, roughly half the length that table promises. An author trusting it would stop writing well short of the length they wanted.
How these were calculated
The two measured books are real: words and images counted in the manuscript, pages counted in the built PDF. The layout settings were read from the two built Word files. Every other figure is computed in code from the formulas above, and the post only builds if the worksheet’s own planning table and an independent calculation agree. Page counts are rounded up to whole pages. The ratios in the page-count table, the sample page counts and the chapter example are illustrative, and the layout-change estimates are geometry on full text pages, not measurements. Your printer’s or platform’s own page count of your final file is the one that counts.
One counting tip from building these: do not trust the page or word count stored inside a .docx file’s properties. On one of the books above it reported 23 pages and 14,014 words for a file that was 109 pages and 24,627 words. Export to PDF and count the pages there.

If you want to do this on your own books, the worksheet has the two measured examples, the planning table at three ratios, and a grid to log words, images and built pages for each book on your template:
