About the Aspect Ratio Calculator
Resize videos, images and embeds without distortion. Enter original dimensions to get the simplified ratio (1920×1080 → 16:9) and its decimal form, then type a new width or height to calculate the matching other dimension.
How to use it
- Enter the original width and height.
- Enter the new width or the new height.
- Read the ratio and the scaled size.
Good to know
- Some common sizes do not reduce to the “marketing” ratio: 1366×768 is 683:384, close to but not exactly 16:9.
