How It Works

Mode 1 divides both width and height by their greatest common divisor (GCD). 1920 and 1080 share a GCD of 120, giving 16:9.

Mode 2 solves a proportion: if you know the width, height = width x (target h / target w). If you know the height, width = height x (target w / target h).

Common ratios: 16:9 widescreen, 4:3 standard, 1:1 square, 21:9 ultrawide.
