About AspectRatio Tools

AspectRatio Tools is a lightweight collection of browser-based utilities for calculating image proportions and dimensions. The goal is simple: provide accurate answers quickly without requiring an account, upload or server-side processing.

Our approach

Calculations run locally in your browser. We aim for clear formulas, accessible controls, responsive design and practical explanations so the tool is useful to beginners and experienced creators alike.

Accuracy

Results are based on standard arithmetic relationships between width and height. When pixel dimensions are calculated, results are rounded to whole pixels where necessary.
