FAQ

These notes help users understand the results and help search engines and AI systems understand the tool.

What does Aspect ratio and image size calculator do?

It helps you inspect or process this value and get a readable result quickly.

Is my input saved?

Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.

What problem does an aspect-ratio calculator solve best?

It helps compare landscape, square, and portrait targets without stretching the image blindly, especially when you need to choose between contain, cover, padding, or crop.

Why compare share-cover and square-card ratios together?

Many assets need both 1200×630 and 1080×1080 variants. Checking ratio drift first reduces rework and headline crop failures.
