What is the DPI Calculator?

DPI (dots per inch) links an image’s pixels to its printed size. 300 DPI is the standard for sharp photo prints, 150 DPI is fine for posters seen from a distance. Choose what you want to find and enter the other two values.

How to use the DPI Calculator

  1. Choose a mode: print size, pixels needed, or DPI.
  2. Enter the known values.
  3. See the result and a quality rating.

Formula

Pixels = inches × DPI, so Inches = pixels ÷ DPI and DPI = pixels ÷ inches.

This DPI Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
