Image Aspect Ratio Calculator

Calculate and simplify image aspect ratios, or solve for a missing dimension


Calculate a Missing Dimension

Know one dimension and want the other for a given ratio? Fill this in.

Enter an image's width and height to instantly see its simplified aspect ratio, decimal ratio, and closest common ratio (like 16:9 or 4:3). Or use the second calculator to solve for a missing width or height given a known dimension and target ratio.
