Screen Aspect Ratio & Dimension Calculator

The aspect ratio of an image is its displayed width divided by its height (usually expressed as "x:y" or "x×y," with the joining colon or multiplication symbol articulated as the preposition "by" or sometimes "to"). For instance, the aspect ratio of a traditional television screen is 4:3, or 1.33:1.

This tool helps you to calculate and compare aspect ratio for given dimensions.
