Frequently asked questions
What is the most popular KDP trim size?
6 × 9 in is the most common for novels and non-fiction, 8.5 × 11 in for workbooks, puzzles and coloring books, and 8.5 × 8.5 in for picture books.
Does trim size change the cost?
Yes. KDP prices large trims (anything over 6.12 × 9 in) higher in many cases, so a bigger trim can cost more to print.
Can I use a custom trim size?
KDP supports custom sizes between 4 × 6 in and 8.5 × 11.69 in. The standard trims here are the safe choice because they print and ship everywhere.
