How to Calculate Print Size From Pixel Dimensions
The physical size of any printed photo depends on its pixel resolution and the printer's target DPI. To determine print dimensions in inches and centimeters:
Print Width (Inches) = Pixel Width ÷ Target DPI
Example: A 3000 × 2400 pixel image printed at 300 DPI yields a 10 × 8 inch photograph (25.4 × 20.3 cm).
Megapixels = (Width × Height) ÷ 1,000,000
Example: A 4032 × 3024 smartphone photo has 12.19 Megapixels, suitable for up to a 13.4 × 10.0 inch 300 DPI fine print.
