Why this exists
Pixel-to-print arithmetic is simple and still gets done badly: DPI tags are mistaken for sharpness, 8×10 orders surprise people who shot 3:2, and the 300 DPI rule is applied to billboards. PrintFit puts the file, the paper, and the viewing distance on one screen.
How it is built
All tools run in the browser. Dropped photos are decoded locally and are not sent to a server. There is no user account and no database of images. Formulas are documented on the methodology page so anyone can reproduce a result with a calculator.
Advertising
Advertisement regions are rendered only when a valid publisher account and slot are configured. They remain labelled and separated from primary controls. Third-party ads are described in the privacy and cookie policies.
Some resource links may become affiliate links. They are disclosed on the resource page and do not affect formulas, quality labels, or editorial ranking.
