Make a page map before final artwork
Fold a few sheets into a small dummy book. Write what happens on each page, including the title, copyright and any end matter. Turn the pages as you read aloud. This catches awkward pauses and scenes revealed too early.
A page is one side of a sheet; a spread is two facing pages. Label your plan clearly. “Twelve illustrations” could mean twelve individual pages, twelve spreads or twelve smaller pictures placed among text. Those are very different layouts.
Match the format to the story
Choose trim size and binding before finalizing paintings. Check the selected printer’s color option and page-count limits. Do not assume that a familiar 32-page picture-book structure is available in every combination of paper, ink and binding.
Leave planned space for the text. Placing words over a busy image at the last minute can make a beautiful spread difficult to read. A quiet area in the composition gives both the painting and the story room.
Send original artwork
KDP calls for images of at least 300 DPI. At 8 × 10 inches, 2400 × 3000 pixels gives 300 pixels per inch before any cropping or bleed allowance. Exporting a small image at a larger pixel size does not restore missing detail.
Keep a high-quality original and send a separate production copy. Label each image to match the page map. If artwork crosses the center, keep important expressions and words away from the binding.
Review the whole reading experience
Read the proof aloud at actual size. Check the smallest text, page turns, credits and image placement. Screen color is not a reliable substitute for a printed proof; order one through the chosen printer.
Our illustrated-book service works from your manuscript, images and intended format. Include the page map and a representative illustration in the planning discussion. Your quotation identifies the agreed files and revision rounds before production begins.
