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.
