Answer

# What size should a KDP sudoku book be?

Updated 15 September 2026

The most popular sudoku trims are 6 by 9 inches for a standard book and 8.5 by 11 inches for large print. One puzzle per page reads best; large print sells well to older solvers.

Pick a [trim size](https://www.oncebooks.com/glossary#kdp-trim-size) by audience: 6 by 9 is compact and cheap to print, while 8.5 by 11 gives a big, easy-to-read grid for the large-print market. You can export the same book at any trim without regenerating.

[Publisher Studio](https://www.oncebooks.com/kdp-sudoku-maker) sizes the interior with the right margins and gutter for your page count, so it passes KDP review.
