What Aspect Ratio Calculator is for
Enter a width, height or ratio and calculate the matching dimension for a target aspect ratio. Includes common presets for video and print.
The Aspect Ratio Calculator is part of the Utilities collection on ToolFlow. It is designed for one concrete job: scale dimensions without distortion. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases
- Resize a video frame
- Crop for social media
- Fit an image into a layout
Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.
