How to Use This Calculator
- Enter the Print Width and Print Height in inches for the final output size.
- Enter the Viewing Distance in feet — larger prints at longer distances need fewer DPI.
- Review Required DPI for optimal print quality at that viewing distance.
- Check Total Pixel Width, Height, and Megapixels Needed to verify your source file has enough resolution.
- Use the DPI requirement to set up your file correctly in Photoshop, Lightroom, or print RIP software.
How the result changes with Viewing Distance
| Viewing Distance | Required DPI |
|---|---|
| 10 | 344 |
| 35 | 98 |
| 65 | 53 |
| 90 | 38 |
What each input means
- Print Width
- Width of the printed output in inches.
- Print Height
- Height of the printed output in inches.
- Viewing Distance
- Expected distance viewers will be from the print.
