About Aspect Ratio Helper
A focused website for one practical task.
Purpose
Resize a graphic or video without stretching it. Enter original dimensions and a target width; the calculator returns the matching height.
The tool is intended to work without accounts. In this starter version, calculations run in the browser and there is no form-submission backend.
Accuracy and limitations
Ratio simplification rounds fractional dimensions to whole numbers. This tool does not resize image files.
Formulas and assumptions are shown so visitors can review the result; no particular outcome is guaranteed.
