KDP Bleed vs No Bleed Explained: Visual Guide & Safe Margin Formulas

One of the most confusing steps during KDP manuscript upload is checking the 'Bleed' or 'No Bleed' radio button. Selecting the wrong option results in either white edges on full-bleed illustrations or automatic review rejection. Here is everything you need to know.

What is 'Bleed'?

In commercial printing, 'bleed' refers to artwork, background colors, or graphics that extend all the way to the very edge of the physical page without leaving any white border. Because printing presses print on large sheets of paper that are mechanically trimmed by blades, machines have a microscopic margin of error. Bleed ensures that if the blade cuts 1/16th of an inch off, there is still color extending past the cut line, preventing an ugly accidental white stripe.

Exact Dimension Calculations for Bleed

If your book uses **Bleed**, you must add **0.125" (3.2 mm)** to page width and **0.25" (6.4 mm)** to page height (0.125" on top + 0.125" on bottom): - **6" × 9" with Bleed**: Manuscript page size must be **6.125" × 9.250"**. - **8.5" × 11" with Bleed**: Manuscript page size must be **8.625" × 11.250"**.

When Should You Choose 'No Bleed'?

• Lined notebooks where lines stop before the edge.
• Sudoku and puzzle books where grids are centered on a white page.
• Standard text novels and non-fiction books.

When Must You Choose 'Bleed'?

• Children's illustrated picture books.
• Coloring books where backgrounds or patterns touch the page borders.
• Planners with colored tab markers or edge bleed headers.
