Aspect Ratio Calculator
Enter a known width and height (or ratio) plus one new dimension to find the other, or simplify any ratio to its lowest terms. Works for any image, video, or display - not tied to a specific platform.
What this tool does
Enter a known width and height (or ratio) plus one new dimension to find the other, or simplify any ratio to its lowest terms. Works for any image, video, or display - not tied to a specific platform.
Formula
Ratio = original width / original height. A new height is calculated as new width / ratio; a new width as new height × ratio. The simplified ratio divides both dimensions by their greatest common divisor.
Frequently asked questions
Is this different from the Zoom-specific aspect ratio calculator?
Yes - this handles any width/height pair for any use case (photos, video, print, displays) and also simplifies ratios to lowest terms, rather than being scoped to Zoom's specific virtual-background presets.
