Word count to page count
Your cover designer needs the spine width before your interior is finished, and the spine comes from the page count. Put in your word count and how you'll set the book, and get a page count you can plan with, for every common size at once.
The same book at other sizes
| Trim size | Pages | Words a page |

Fewer pages means a cheaper book to print and a thinner spine; bigger pages hold more words but feel less like a novel.
How good is the estimate?
We checked it against real typesetting: five books of different sizes, fonts and styles, set by the same engine as our book file maker. Every estimate came within 6% of the real page count, so plan with the range, not just the middle number. Your formatting program will differ a little: spacing between scenes, front and back matter, and how it handles the ends of paragraphs all move it.
For the exact number
Make your print PDF (in Vellum, Atticus, Word, or our free book file maker) and count its pages, blank ones included. Then give your designer the spine width for that count. If the page count changes after the cover's made, the spine has to change too.
