Ratio Simplifier
Reduce a ratio to its simplest whole-number form.
Ratios in simplest form
Dividing both sides by their greatest common divisor simplifies a ratio: 1920:1080 reduces to 16:9, the aspect ratio behind most screens. This does it for any pair of numbers.
It is the fast way to reduce a screen or image ratio, mix proportions in a recipe or paint, or express a data split like 250:1000 in its cleanest 1:4 form.
Where it helps
Simplified ratios make proportions and aspect ratios easy to compare. The math runs entirely in your browser with nothing uploaded. Your numbers stay in the browser and are never uploaded.
