Amazon KDP Book Cover Builder

Your book cover is the single most important factor in whether a reader clicks on your book on Amazon. A professional-looking cover signals quality and builds trust. Our KDP Cover Builder makes it easy to create print-ready covers with the exact dimensions Amazon requires.

Unlike generic design tools, this builder is purpose-built for Amazon KDP paperback covers. It includes proper bleed margins (0.125"), safe zones (0.25"), and exports at the required 300 DPI resolution. No guesswork, no rejected uploads.

Getting Your Cover Dimensions Right

One of the most common reasons KDP rejects covers is incorrect dimensions. Each trim size has specific pixel requirements at 300 DPI. For example, a 6×9" book needs a cover of 1875×2775 pixels including bleed. Our builder handles all these calculations automatically.

Bleed and Safe Zone Explained

The bleed area (0.125" on each side) is extra space that gets trimmed during printing. Background colors and images should extend into the bleed to avoid white edges. The safe zone (0.25" from the edge) is where all important text and content should stay to avoid being cut off.
