Reading the number

What the verdict means.

The result above comes from one bit of maths: pixels divided by print size. Here is what each band tells you.

300 DPI and up
Crisp. Use it for anything someone holds up close, like a photo magnet, a print, or a card.
150–299 DPI
Fine for larger pieces viewed from a step back, like a wall poster. Too soft for fine detail.
Below 150 DPI
Comes out soft or blocky on paper. Drop to a smaller size, or start from a sharper photo.

Frequently asked

Using the checker.

Do I need to install anything to check DPI?+
No. The checker runs right here in your browser. It is free, there is nothing to download, and you do not need to sign up.
Is my photo uploaded anywhere?+
No. The checker reads your photo size right here in your browser. Nothing gets sent to a server or saved.
What size can I safely print my photo?+
Drop your photo in above and it tells you the biggest size that still lands at 300 DPI, plus the largest size that scrapes by at 150. Past that and the print starts to soften.
