About this app
Resizing a video or image while keeping the exact aspect ratio intact means doing a small proportion calculation every time.
Enter a width and an aspect ratio, and get the correct height calculated instantly, or the other way around.
Covers common ratios like 16:9, 4:3, 1:1, and 9:16, or enter a fully custom ratio.
See the result instantly update as you adjust either the known dimension or the ratio.
Useful for video exports, image resizing, or setting up a canvas at the correct proportions.
A small, exact calculator for a proportion problem that is easy to get slightly wrong by eye.
