Children's Picture Book Covers
Make a cover that reads in a school library thumbnail and still works as a printed 8.5 × 11 board.
The character has to survive the crop
Children's covers are read at two sizes: a small library thumbnail and a wide printed cover. Keep the main character large and clear, and leave room for a title band that can be moved between formats. Avoid detailed scenes where the subject disappears when the image is reduced.
Plan the back and spine for print
Picture books are often 8.5 × 11 in with a short page count, so the spine can be narrow. Run the calculator with the real page count and paper before you design the back cover. If the spine is too thin for text, plan a full-bleed wrap instead.
Choose one readable typeface
The title should be easy to read aloud to a child and easy to scan online. One clear typeface at two sizes is better than a decorative display font with three effects. Check the result in grayscale too; many readers find the book on a phone in daylight.
full cover file size — Picture books are usually printed at a larger trim, so check the full cover file size before you draw anything at final scale.
