How it works
A useful answer,
with the math visible.
Scale an image proportionally to a target width or height and see common print-ratio matches. Adjust the fields above and the result updates immediately—there is no upload, account or hidden processing step.
FORMULATarget height = target width × original height ÷ original width
Worked example
A 3:2 photograph printed 12 in wide is 8 in high without cropping.
Before you send the file
- Changing only one dimension preserves the original ratio.
- A different paper ratio requires cropping or adding borders.
- Check pixel resolution separately before printing at the calculated size.
