To self-publish a children's picture book on Amazon, print it in premium color on white paper, supply art at 300 DPI, choose a trim size like 8.5 x 8.5 or 8.5 x 11 inches, and have at least 24 interior pages. Most picture books go out as a paperback plus a Kindle ebook.
Picture books follow the same basic KDP steps as any book, but color, art resolution and page count change the details. Here's what to get right.
Premium color on white paper. For art-filled pages, choose premium color on white paper in KDP's print options. It costs much more to print than black and white, and that changes your pricing. Before you pick a price, run your page count through the book specs calculator using the premium color option, then confirm in KDP's own royalty calculator. Our royalties guide explains how the math works.
Pick the shape your art already has, from three common sizes.
| Trim size | Shape |
|---|---|
| 8.5 x 8.5 inches | Square |
| 8 x 10 inches | Tall rectangle |
| 8.5 x 11 inches | Tall rectangle, roomier |
Match the shape your illustrator is already drawing in so little gets cropped. Choose the size before the illustrations are finished if you can. Redrawing for a new shape is expensive.
Follow these four rules.
The details on margins and bleed are in our KDP paperback formatting guide. Picture books use the same rules, with bleed turned on.
Where children can read them easily. Use a clear, rounded font between 16 and 22 point. Set the words on the art, in a calm spot, rather than in small text on an empty facing page. Keep contrast strong. Pale letters on a busy picture are hard for small eyes and tired parents reading at bedtime.
At least 24 interior pages. A KDP paperback needs at least 24 interior pages, and the count should be even. Many picture books land around 32 pages total, but check what your layout actually adds up to. Don't count the cover. It isn't part of the interior. It's its own file: a full wrap with back, spine and front. Use KDP's cover calculator, or our guide to cover size and spine width. Books under 80 pages can't carry text on the spine.
Only if it has enough pages. KDP hardcovers need at least 75 pages. Most picture books are shorter, so on KDP most are paperback and Kindle only. If a hardcover matters to you, say for a gift edition, you'd need to plan the page count from the start.
Use Amazon's free Kindle Kids' Book Creator. It builds a fixed-layout ebook, so your pages look the way you designed them instead of reflowing. In KDP, set the reading age and grade range so the book shows up for the right families.
It's a good idea. Teachers and parents love a book that keeps the conversation going after the last page. Consider adding a short discussion page at the back with three to five questions. Ask what a character felt, what the reader would do, or what happened and why. It gives a classroom or a bedtime a reason to reread, and it helps your book stand out from others on the shelf. You can also share the same questions as a free printable for your readers.
Because colors on paper rarely match colors on a screen. Order a printed proof and check the spine, the color of the art, and how close the words sit to the edge. Then hand it to a child and watch where their eyes go. That's free user testing.
Not on Audible. A short picture book is too short for Audible. A video read-aloud is a better use of your voice. Record yourself reading it and share it with schools and parents. If you have a longer book, see how to make an audiobook for Audible.

At least 24 interior pages for a paperback, not counting the cover. The page count should be even.
KDP hardcovers need at least 75 pages, so most picture books are paperback and Kindle only on KDP.
300 DPI at the size it prints. Web images at about 100 DPI print blurry.
