Print Size Calculator
Use pixels ÷ DPI for print inches, choose an acceptable DPI to compare maximum print sizes, or use inches × DPI for required pixels.
A QUICK WALKTHROUGH
How to use this tool
- Enter a pixel size and DPI, or choose a paper preset.
- Review inches, centimetres, millimetres, megapixels, and aspect ratio.
- Use the DPI table to compare print quality.
Two-way print planning
Convert pixels to physical print dimensions, or enter a print size and DPI to get the minimum required pixels. Required dimensions are rounded up.
Acceptable DPI and viewing distance
Choose 150, 240, or 300 DPI to see the largest practical print size for your image and compare alternatives. DPI is a practical reference; the best choice also depends on viewing distance, image detail, and the printer.

Why are required pixels rounded up?
Rounding up ensures the image meets or exceeds the requested print size at the selected DPI.
