REM to PX conversion

REM units are relative to the root element font size. One REM equals the root font size in pixels. Change the base font size above to match your project.

How it works

  • 1 REM = base font size in pixels
  • Most browsers use 16px as the default root size
  • REM scales with the root, so layouts stay consistent when users change font size
  • Use REM for typography and spacing when you want responsive, accessible sizing
