Photo Print Size Calculator

A photo print size calculator divides pixel width and height by DPI to get inches, then centimetres. 6000×4000 at 300 DPI is 20×13.33 in (50.8×33.9 cm). Reverse: an 8×10 at 300 DPI needs 2400×3000 px.

Quick Summary & Direct Answer
Design

How large does a photo print at 300 DPI?

Inches = pixels / DPI. A 24 MP 6000×4000 file is 20×13.33 inches at 300 DPI. At 150 DPI the same file is twice as large on paper and softer.

Key Takeaways

  • 300 DPI is a common photo-lab target.
  • 72 DPI is screen, not a quality print.
  • Presets show pixels needed for 4×6 through A3.

Print inches are pixels divided by DPI

6000×4000 at 300 DPI is 20×13.33 in. The page does not upsample. 8×10 at 300 DPI needs 2400×3000 px.

Viewing distance

Large wall prints are often viewed farther away; 150–200 DPI can be enough. Labs still ask for 300 for albums.
