Aspect Ratio CalculatorA resolution says how many pixels wide and tall an image or screen is; the aspect ratio describes its shape. Many resolutions share one shape — 1280 × 720, 1920 × 1080 and 3840 × 2160 are all 16:9 — while some popular sizes are not exactly the ratio they are sold as.
The tables below give the exact reduced ratio of each size and, where that is not a round number, the standard ratio it is closest to.
