About PrintSizes
How the tool works
PrintSizes is a free browser tool with no sign-up. It covers photo sizes from 2x3 wallet to 12x18, posters from 11x17 to 27x40 (including 24x36), squares, A5 to A1, and custom sizes.
- Add a photo or type in its pixel dimensions.
- See which sizes rate Excellent, Good, Fair, or Poor from the pixels per inch.
- Drag to crop and pick a frame. Same-size frames have no mat; larger frames add a mat with the width worked out for you.
- Preview the framed print in a room at true scale and download a print-ready JPEG.
How sharpness is judged
You hold a small print in your hand, but view a wall print from a few steps back. Bigger prints are viewed from further away and need fewer pixels per inch. Ratings assume a viewing distance of about 1 ft for small prints, about 2 ft for medium, and about 3 ft or more for large. Small prints want about 240 pixels per inch for an Excellent rating; posters need about 150.
Even so, a bigger print never needs fewer total pixels than a smaller one. Changing a file setting to 300 DPI adds no detail, because only real pixels count.
Your photo stays on your device
Your photo never leaves your device. Checking, cropping, and making the JPEG all happen in your browser; nothing is uploaded. Read the full privacy policy.
