Word count to page count at every KDP trim size.
Common manuscript word counts converted to estimated page count at every KDP trim size. Assumes 11pt Times New Roman, 1.15 line spacing, normal margins. Actual page count varies with chapter breaks, blank pages, front matter, and image inserts.

KDP paperback max is 828 pages. If your estimate exceeds 828 at your chosen trim size, switch to a larger trim or split the manuscript into volumes.
Why your real page count will be different.
The calculator assumes continuous body text. Real books rarely look that way. Add roughly 5 to 15 percent to your estimate to account for the following.
Chapter breaks
Every chapter starts on a new page. Often on a right-hand page, which forces a blank verso. Twenty chapters can add 10 to 20 pages.
Front matter
Title page, copyright, dedication, table of contents, and an introduction. Typically 6 to 12 pages combined.
Back matter
About the author, also-by list, acknowledgements, and a sample chapter teaser. Typically 4 to 10 pages.
Blank pages
Books print as signatures of 4, 8, or 16 pages. Your final page count may round up to fill the signature.
Image inserts
Full-page images or photo plates each occupy one page, regardless of word count.
Drop caps and chapter ornaments
A large initial letter or chapter ornament shifts the first paragraph down, costing roughly half a line per chapter.
How long should a book be? Word counts by genre.
What readers expect from each genre. Typical page count assumes 6 by 9 inch trim, 275 words per page. A book that lands inside its genre band sells more reliably than one that sits noticeably above or below.
| Genre | Typical word count | Pages at 6 x 9 |
|---|---|---|
| Flash fiction | 500 to 1,500 | under 6 pages |
| Short story | 1,500 to 10,000 | 6 to 36 pages |
| Novella | 20,000 to 40,000 | 73 to 145 pages |
| Young adult novel | 50,000 to 80,000 | 182 to 291 pages |
| Romance novel | 70,000 to 100,000 | 255 to 364 pages |
| Mystery / thriller | 70,000 to 90,000 | 255 to 327 pages |
| Literary fiction | 80,000 to 100,000 | 291 to 364 pages |
| Science fiction | 80,000 to 110,000 | 291 to 400 pages |
| Fantasy | 90,000 to 120,000 | 327 to 437 pages |
| Epic fantasy | 100,000 to 200,000 | 364 to 727 pages |
| Memoir | 60,000 to 90,000 | 218 to 327 pages |
| Self-help / business | 30,000 to 70,000 | 109 to 255 pages |
The math behind the estimate.
Words per page is a function of trim size, font size, line spacing, margins, and font family. We start from a base words-per-page for each trim and apply multipliers for the other variables.
Formula
Pages = ceil(Words / (Base WPP × Font × Spacing × Margin × Font Family))
Worked example
- Word count: 75,000
- Trim: 6 x 9 inches (275 base words/page)
- Font: 11pt Times New Roman (multiplier 1.0)
- Line spacing: 1.15 (multiplier 1.0)
- Margins: Normal (multiplier 1.0)
- Effective WPP: 275
- Pages = ceil(75,000 / 275) = 273 pages
- Spine width = (273 × 0.002252) + 0.06 = 0.6749"
Font size multipliers
- 10pt: +15% words/page
- 11pt: baseline
- 12pt: -12% words/page
Line spacing multipliers
- Single (1.0): +25% words/page
- 1.15: baseline
- 1.5: -22% words/page
- Double (2.0): -38% words/page
Word count to pages, answered.
How many pages is 50,000 words?
A 50,000 word manuscript is approximately 182 pages in a standard 6 by 9 inch book with 11pt font and 1.15 line spacing (about 275 words per page). In a smaller 5 by 8 inch format it would be around 250 pages. Page count varies with trim size, font, line spacing, and margins.
How many words per page in a book?
A typical book page contains 250 to 300 words in a 6 by 9 inch format with standard 11pt font and 1.15 line spacing. Smaller trim sizes like 5 by 8 inches fit about 200 to 225 words per page, while larger 8.5 by 11 inch workbooks can hold 400 to 450 words per page.
How long should a novel be?
Most novels fall between 40,000 and 100,000 words. Genre conventions vary. Romance novels typically run 70,000 to 100,000 words, thrillers 70,000 to 90,000, fantasy 90,000 to 120,000, young adult 50,000 to 80,000, and literary fiction 80,000 to 100,000. Epic fantasy can stretch to 200,000 words.
How many pages is 80,000 words?
An 80,000 word book is approximately 291 pages at 6 by 9 inches with 11pt font and 1.15 spacing. In a 5.5 by 8.5 inch format it would be around 334 pages. This is a common length for a debut novel.
How many pages is 100,000 words?
A 100,000 word manuscript is approximately 364 pages at 6 by 9 inches with 11pt font and 1.15 spacing. At 5.5 by 8.5 inches it would be around 417 pages. At 5 by 8 inches it would be approximately 500 pages, which is close to the comfortable readability limit at that trim size.
How many pages is 40,000 words?
A 40,000 word manuscript is approximately 145 pages at 6 by 9 inches with 11pt font and 1.15 spacing. In a smaller 5 by 8 inch format it would be around 200 pages. At 40,000 words you are in novella territory, long enough for KDP paperback (minimum 24 pages) but shorter than most genre novels.
What is the minimum page count for KDP?
KDP requires a minimum of 24 pages for paperback books and 75 pages for hardcover books. The maximum is 828 pages for paperback and 550 pages for hardcover. KDP also requires at least 79 pages before you can place text on the book spine, regardless of paper type.
How do I calculate spine width for my book cover?
Spine width depends on page count and paper type. For KDP white paper, multiply page count by 0.002252 inches and add the 0.06 inch cover allowance. A 300 page white paper book has a spine of (300 x 0.002252) + 0.06 = 0.7356 inches. The calculator above gives you spine width automatically, and the spine width calculator covers all paper types.
Does font choice affect page count?
Yes, font choice changes page count by about 5 to 10 percent. Garamond is more compact than Times New Roman and fits roughly 5 percent more words per page. Georgia is slightly wider and fits about 5 percent fewer words per page. Within the same font, 10pt fits more than 11pt fits more than 12pt.
What trim size should I use for my book?
The most popular trim size for novels is 6 by 9 inches or 5.5 by 8.5 inches. For non-fiction and self-help, 6 by 9 inches is the standard. Children's books often use 8.5 by 11 inches. Smaller trim sizes feel like mass-market paperbacks but produce more pages, which raises print cost. Larger trims look professional but read fewer pages, which can affect perceived value.
How does line spacing affect page count?
Line spacing has a major impact. Switching from 1.15 spacing to double spacing can increase page count by roughly 60 percent. Single spacing reduces it by about 20 percent compared with 1.15. Most published novels use 1.15 to 1.3 line spacing, which balances readability and density.
Does a higher page count hurt my KDP royalty?
Higher page count increases printing cost, which reduces net royalty per sale. KDP's 60 percent paperback royalty is (List Price x 0.60) minus Printing Cost, and printing cost scales directly with page count. Comparing trim sizes here helps you find a format where your royalty stays healthy at your target list price.
