Children's Picture Book Cover Prompts for KDP Paperbacks
A children's picture book cover has to promise a story, a character and a feeling before the parent ever opens it. These prompts set up full paperback covers for a bedtime book, an adventure about a brave little mouse and a first-day-of-school story, each with an original character. They are sized for square and letter picture books printed in color on both sides.
Bedtime picture book cover
Size
8.5 × 8.5 in
Interior
story book, 16 sheets
A soft, dreamy bedtime cover: a sleepy little bear in striped pajamas sitting on a crescent moon, holding a glowing lantern, above a quiet village of rooftops and pine trees. Deep blue night sky with soft stars, warm golden lantern light, a gentle and cozy mood. The back cover continues the starry sky with a short blurb area. For ages 2-6.
Why it works: Bedtime books are an evergreen gift category, and a calm blue-and-gold palette tells parents at a glance that this book winds kids down.

Brave mouse adventure cover
Size
8.5 × 8.5 in
Interior
story book, 16 sheets
An adventurous storybook cover: a tiny gray mouse in a red scarf standing on the rocks at the foot of a tall striped lighthouse, holding a small lantern up against a stormy sea. Crashing waves, a gull, a warm beam of light cutting through blue-green clouds. Brave, warm and a little exciting, for ages 4-8. The back shows the calm harbor at sunrise.
Why it works: Self-publishing authors need a cover that sells a small hero facing a big challenge, the core promise of a read-aloud adventure.

First day of school picture book cover
Size
8.5 × 11 in
Interior
story book, 20 sheets
A cheerful, reassuring cover: a girl with brown skin, curly hair and a yellow backpack standing at the open doors of a bright school, a little nervous but smiling, with a friendly classmate waving from the steps. Autumn leaves, a red school bus and a sunny morning sky. Warm, encouraging, for ages 4-7. The back shows the two friends walking home together.
Why it works: First-day-of-school books sell every July and August, and a cover showing nerves turning to friendship speaks straight to anxious parents.

Tips for making a children's picture book cover
Put the main character large on the front and looking toward the story; readers bond with a face.
A 32-page picture book printed on both sides is 16 sheets; KDP's minimum is 24 pages, which is 12 sheets.
Choose color interior paper for picture books so the cover's spine width matches a full-color book.
