Print size and DPI calculator
Check if a photo is big enough for a print, find the pixel size a print needs, and see how much gets cropped. Everything is calculated in your browser.
How it works
Pixels needed = inches × DPI. An 8 × 10" print at 300 dpi needs 2400 × 3000 pixels.
Largest print = pixels ÷ DPI. A 6000 × 4000 photo prints at up to 20 × 13.3" at 300 dpi.
Cropping happens when the photo and the print have a different shape. A normal 3:2 camera photo loses about 17% of its long side on an 8 × 10". After cropping, the calculator shows the real DPI the print will get.
What DPI do I need?
- 300 dpi is the standard for photo lab prints you hold in your hand: wallets, 5 × 7", 8 × 10", composites and memory mates.
- 200 to 240 dpi usually still looks sharp, which helps when a photo is cropped tight.
- 150 dpi is common for posters and banners that are seen from further away.
Always check your lab's specs. For a full chart of sizes, see sports photo print sizes and pixels at 300 dpi.
