Why does my KDP coloring book page have a white border?
Short answer: A white border usually appears when artwork does not fill the page canvas, the wrong fit mode is used, the PDF is no-bleed while the art is meant to reach the edge, or the source image already contains a white margin. Check bleed settings, image fit, and the final KDP Previewer result.
Why this causes KDP problems
Full-page coloring art needs a page canvas and placement choice that match the publishing setup. If an image is centered with extra whitespace, or if a bleed page is built at no-bleed size, the final printed page may show an unintended edge.
Recommended workflow
- Inspect the source image for built-in white margins.
- Choose bleed if artwork is meant to reach the page edge.
- Use a fit mode that matches the artwork style.
- Generate a preview PDF and inspect affected pages.
- Check the final export in KDP Previewer.
Where Book Interior Kit fits
Book Interior Kit applies a consistent page canvas and fit mode across imported artwork. That helps authors catch repeated border and page-sizing mistakes before exporting an interior PDF.
What to check before publishing
- Bleed or no-bleed mode matches the KDP setup.
- The artwork is not surrounded by an unwanted source-image margin.
- Full-page pages reach the intended page edge.
- The final PDF is reviewed in KDP Previewer.
