How to make a coloring book for KDP

A good coloring page has closed shapes, clean lines and areas sized for the hand holding the crayon. The print side is simpler than a picture book: black ink, one picture per page.

1. Match the detail to the age

• Very simple (about 2–4): thick outlines, a few large shapes, almost no background.
• Simple (about 4–8): clear outlines, some background, nothing tiny.
• Detailed: for older children and adults; smaller areas and patterns.
• Intricate: for adults; dense patterns and fine lines.

These are the four levels in kdpbookai. The level goes into every drawing request, so line weight and area size stay the same across the book.

2. Print settings

The kids coloring type offers 8.5 × 11 in, 8 × 10 in and 24–100 pages. Black ink on white paper is the usual choice; color paper adds cost without adding anything to a page meant to be colored.

3. Is a coloring book low-content?

Usually not. KDP's own note: "Coloring and puzzle books are generally not low-content." Low-content is meant for books like planners and lined journals. Read low-content books before you tick that box.

4. Check every page

• Lines are closed, so color stays inside a shape.
• Nothing important sits near the trim edge or the spine.
• No gray shading or filled black areas you did not want.
• The cover and the inside match the age you name in the description.

kdpbookai measures every drawn page for gray shading and heavy black areas, flags the ones that need another try, and redraws a single page on request.
