How DPI Calculation Works

DPI connects digital pixel dimensions with physical print dimensions.

DPI Formula

Physical Width (inches) = Pixel Width ÷ DPI
Physical Height (inches) = Pixel Height ÷ DPI
Centimeters = Inches × 2.54
Millimeters = Inches × 25.4

Example

A 3000 × 2000 pixel image at 300 DPI produces a physical print size of:

10 × 6.67 inches
25.40 × 16.93 cm
