About

Print Ready Tools provides free browser-based calculators for print sizes, DPI, bleed, safe zones, KDP paperback setup and Etsy printable files. We are independent and not affiliated with Amazon, Etsy, Canva or Adobe.

Formula or rule

Use physical size × DPI for pixel requirements. For bleed, add bleed to both sides. For KDP covers, use back cover + spine + front cover + outside bleed.

Worked example

At 300 DPI, an 8 × 10 inch print needs 2400 × 3000 pixels. A 6 × 9 inch KDP interior with bleed becomes 6.125 × 9.25 inches.

Limits

Printer, paper, marketplace and software requirements vary. Use official platform templates as the final check.
