Square vs portrait books

Match page shape to artwork and marketplace constraints.

Short answer

Portrait trims suit conventional reading and many print presets; square trims work well for centered visual compositions but may increase large-trim printing cost.

Steps

  1. Compare artwork aspect ratios.
  2. Check the marketplace trim list.
  3. Test one representative spread before building all pages.

How to verify the result

Example: prepare a 24-page image-based activity book and its blank cover template.

Check: This is not KDP certification and does not implement DOCX, EPUB, or cloud project storage.
