Children’s Book Bleed and Trim Size for KDP
Trim and bleed decisions affect every illustration you generate, so choose them early.
Why trim size comes first
If you switch trim sizes late, art may need reframing and text areas can break. Fixing this early gives you cleaner composition and fewer production edits.
Simple setup process
- Choose target trim size for your book format.
- Define bleed/non-bleed page strategy.
- Reserve safe text zones in every composition.
- Use one page ratio for all generated scenes.
How MyStoryBot helps planning
MyStoryBot helps you iterate on scenes and page text quickly so you can validate visual balance before finalizing your export and print layout files.
Choosing trim direction by audience
- Square formats often work well for younger read-aloud audiences.
- Portrait can support text-heavy pages and calmer compositions.
- Landscape can support action scenes and wide environments.
- Pick one direction early and keep it fixed throughout production.
Bleed decision rule
Use bleed when artwork reaches page edges. Use non-bleed when you want visible margins and simpler text placement. Mixing both approaches without a clear plan usually creates rework late in production.
