Description
How to calculate aspect ratioAs a decimal
Divide width by height. A 1920×1080 screen is 1920 ÷ 1080 = 1.7778, so the decimal form is 1.7778:1. Pixels, inches and centimetres all work when both sides share one unit. The unit label can be left off, because the ratio is only a proportion.
As whole numbers
Divide both sides by their greatest common divisor. 1920 and 1080 share 120, which leaves 16 and 9. The aspect ratio calculator uses that reduction, then names the nearest standard ratio when the exact fraction is awkward. 1366 and 768 share 2, so the exact ratio is 683:384, about 0.05% from 16:9.
About Aspect Ratio Calculator: type a width and a height for the simplified ratio, or a ratio and one side for the other side in pixels. Video, photos, print and screens are typical jobs.
