How to Use the Aspect Ratio Calculator
This calculator helps you find the aspect ratio or a missing dimension (width or height). Enter any two values to get the third.
- Width & Height: Enter both to calculate the simplified aspect ratio (e.g., 16:9).
- Width & Ratio: Enter width and a ratio (e.g., 16:9) to calculate the missing height.
- Height & Ratio: Enter height and a ratio to calculate the missing width.
- Only Ratio: Enter a ratio alone to simplify it (e.g., 32:18 becomes 16:9).
Format: Use positive numbers for dimensions. Ratios must use a colon (e.g., 16:9). Results show in pixels with two decimal places.
