PX to REM Converter
Convert pixels to rem (and back) for scalable typography.
Sizing type in rem keeps a layout flexible and respectful of whatever font size a visitor has set in their browser. Enter a pixel value against your root font size — 16px by default — and read back the precise rem equivalent, or convert the other way.
Why rem is worth the habit
- Designs built in rem scale cleanly when someone bumps up their default text size.
- It is a genuine accessibility win, and accessible pages tend to perform better in search.
- Set the project root size once and measure everything consistently against it.
