FAQ

Common questions

How do I convert pixels to centimeters?

Divide pixels by DPI to get inches, then multiply by 2.54 to get centimeters.

Can I use pixels to cm for screens?

This conversion is mainly for physical output. Screen display size depends on device pixel density, browser zoom, and CSS scaling.

Can I share selected tool settings?

Some PixelMeasures tools keep selected presets in the URL fragment, so a shared link can reopen useful choices while the main tool page stays focused.
