About Aspect Ratio Solver

Aspect Ratio Solver is built and maintained under the Aspect Ratio Solver name. It is an independent tool for calculating aspect ratios and proportional dimensions.

What this tool does

Use original dimensions to find a simplified ratio, or use a ratio and a known side to calculate a missing dimension. You can also calculate dimensions from a ratio and a diagonal, choose resolution presets, preview the output shape, and copy your result.

The calculator runs in your browser. It calculates dimensions; it does not upload, crop, resize, or export image files. It handles one calculation at a time, with no account or saved calculation history.

Numbers you can check

The calculator displays the formula used for your result. Its supported-format notes link to the sources used for presets. Rounded pixel dimensions can change the exact ratio, and displayed decimal results are limited to six places.
