Page guide

Find the simplest ratio for your image or screen dimensions.

How to use Aspect ratio calculator
  1. Enter the values you want to calculate and choose the relevant units or settings.
  2. The result updates as you type. Adjust the available settings if needed.
  3. Review the result, then use Copy result or a download link when available.

What to expect

Find the simplest aspect ratio from a width and height. Enter positive whole-number dimensions in the same unit. A 1920 × 1080 rectangle reduces to 16:9.
