Pixels to Inches Calculator

Convert between pixels and inches at any DPI setting. The result depends entirely on DPI: 300 pixels at 96 DPI (web) is 3.125 inches, but at 300 DPI (print) it is just 1 inch. This calculator also shows centimeters, millimeters, and typographic points.

Pixels are a digital unit with no fixed physical size. The physical size depends on the resolution (DPI, or dots per inch) of the output device.

The Formula:

  • Inches = Pixels / DPI
  • Pixels = Inches x DPI

Common DPI Values:

DPI Typical Use
72 Classic Mac screen resolution
96 Windows default screen resolution
150 Low-quality print
300 Standard print quality
600 High-quality print
1200+ Professional photo printing

Pixels to Inches at Common DPIs:

Pixels 72 DPI 96 DPI 150 DPI 300 DPI
100 1.39" 1.04" 0.67" 0.33"
300 4.17" 3.13" 2.00" 1.00"
600 8.33" 6.25" 4.00" 2.00"
1080 15.00" 11.25" 7.20" 3.60"
1920 26.67" 20.00" 12.80" 6.40"

Practical tip for print design: If you want a 4x6 inch photo at 300 DPI, you need an image that is 1200 x 1800 pixels. Lower resolution images will look pixelated when printed at larger sizes.
