Why publishers switch
KDP's spine formula depends on paper type and page count. One millimetre off = instant rejection.
Spine auto-calculated using KDP's official formula for every book.
KDP requires exactly 0.125″ bleed on all sides. Most designers forget or get it wrong.
Automatic bleed applied and visible in your canvas. Every export includes it.
Canva exports at 96 DPI by default. KDP requires 300 DPI minimum — causing blurry print results.
Export a 300 DPI print-ready PDF. Guaranteed crisp, sharp printing.
Everything you need
Every tool purpose-built around Amazon KDP's specs so you don't have to figure them out yourself.
Exact spine width for every paper type and page count — matches KDP's official formula to the thousandth of an inch.
Auto 0.125″ bleed on all sides with safe-zone guides visible in the canvas editor. Never miss a margin.
Generate professional cover concepts by genre and mood in seconds, then customise everything in the editor.
Upload your Canva design and we correct dimensions, add bleed, and prepare the full wrap for upload automatically.
Download at 300 DPI with correct bleed, meeting every KDP specification. No blur, no rejections.
Every KDP requirement validated before export. Know your cover will pass before you even upload.
