Aspect Ratio Calculator
Divide width by height to describe a frame's numeric aspect ratio.
Use matching units and simplify or round the displayed ratio when preparing a format spec.
What the result means
The result describes width divided by height, shown as a decimal ratio. It does not set a platform's export requirements.
The formula
Width / height
Results are displayed to at most two decimal places. Calculations use the unrounded inputs.
A worked example
Put the formula to work
- Width (pixels or units)
- 1,920
- Height (pixels or units)
- 1,080
Width-to-height ratio: 1.78x
1920 divided by 1080 is approximately 1.78x, commonly written 16:9.
How to use this calculator
- Enter width and height in matching units.
- Divide width by height.
- Round or simplify for the intended spec.
- Confirm delivery requirements separately.
Why this number matters
A numeric ratio makes orientation and framing constraints easy to communicate.
Input definitions
- Width (pixels or units)
- Frame width.
- Height (pixels or units)
- Frame height; must be greater than zero.
Assumptions and limitations
- Cropping and platform safe areas are not represented.
- No export codec or quality recommendation is implied.
Methodology
The default result and worked example use the same calculation functions as the interactive tool. The formula cannot verify the quality or scope of your source data.
