DPI vs PPI: What You Actually Need for Print and Web

For screens, only pixel dimensions matter — DPI is ignored. For print, DPI (dots per inch) controls how large the pixels are on paper. 300 DPI is the standard for sharp photo prints and documents.

See DPI and PPI for precise definitions.

Set a print resolution with 300 DPI Photo or 600 DPI for fine prints, or change it with Convert DPI. Check what an image currently has with DPI Checker.

For physical sizing, Resize in cm, Resize in mm and Resize in inches convert real-world sizes to exact pixels at your chosen DPI.
