PX to REM Converter

Converting pixels to REM units is essential for modern, accessible web design.

Why use REM?

  • Accessibility: REM units scale based on the user's browser font size settings. PX units are fixed and ignore user preferences.
  • Responsiveness: It makes building responsive layouts easier as you can scale the entire site by changing the root font size.

*This calculator assumes the standard root font size of 16px.
