Coloring styles
Every design is drawn in the style you pick, then cleaned to pure black and white before layout:
- Kids coloring (cartoon): Cute cartoon scenes in clean medium-weight outlines with regions sized for crayons.
- Bold & easy coloring: Thick uniform outlines and big simple shapes: the easiest coloring style to see and to color, for kids, beginners and seniors.
- Realistic line drawing: Accurate, naturalist contour drawings: animals, plants and places as they really look.
- Intricate adult coloring: Every shape filled with fine decorative patterns (florals, paisley, feathers) for relaxing, detailed coloring.
- Mandala: Radial, symmetrical mandala patterns woven around the subject.
The book form also offers kawaii, Scandinavian folk, Victorian engraving and naturalist plate, drawn in black and white. You can also describe your own line style in words or upload a reference image.

Questions
Can kdpbook.io make coloring books for adults as well as kids?
Yes. kdpbook.io has two coloring book types: the kids' coloring book (ages 0–8), with styles such as kids coloring (cartoon) and bold & easy coloring, and the adult coloring book (ages 13+), with styles such as bold & easy coloring, intricate adult coloring and mandala. Both turn a one-line theme into black-and-white line art.
What size is a coloring book made with kdpbook.io?
The default kids' coloring book is 8.5 × 11 in, black & white interior with white paper, 106 pages. You can switch to 8.5 × 8.5 in, 8 × 10 in, 8.25 × 11 in or 8.27 × 11.69 in (A4), and the adult coloring book also offers 8.25 × 8.25 in; the layout and the cover are recalculated for the new size.
Are the coloring pages printed on one side?
Yes, by default, in both types: one design per sheet with a blank back, so neither kids’ markers nor adults’ alcohol markers bleed onto the next design. For crayons or colored pencils, switch either book to both sides: the same page count then holds about twice as many designs.
Can I sell a coloring book made with kdpbook.io on Amazon?
Yes. To sell the book, export it on a paid plan: every plan from $25/month (Starter, 2,500 credits a month) gives watermark-free files with a commercial license, and kdpbook.io takes no royalty. Free-plan exports carry a “kdpbook.io preview” watermark and are not for sale. KDP asks you to declare AI-generated images, the cover included, when you publish (KDP Help, Content Guidelines, checked September 28, 2026).
Does a coloring book need an ISBN on KDP?
Yes. KDP says low-content books don’t typically include coloring books, so you publish with an ISBN (the free KDP ISBN is fine), which also gives the book Look Inside. Coloring books are print only, because KDP lists them as unsuited to Kindle, and KDP’s distributors don’t accept them for Expanded Distribution (KDP Help, checked September 28, 2026).
How much does an AI coloring book cost on kdpbook.io?
A default 106-page kids' coloring book with 50 designs comes to about 1,803 credits (about $18), and a 106-page adult coloring book to about 1,803 credits. The exact estimate is shown before launch. The 2,000 free signup credits cover one, but free-plan exports carry a “kdpbook.io preview” watermark and are not for sale.
