Trim size is the final width and height of your printed book after it’s been cut at the printer.
Common trim sizes (in inches) include:
- 5” x 8”
- 6” x 9”
- 8.5” x 11”
Trim size affects layout, page count, cost, and how your book appears on a shelf. Most platforms let you select from predefined trim sizes — just ensure your interior and cover are formatted to match.
