What is a PX to REM Converter?

This tool allows you to easily convert any pixel (px) value into its equivalent rem (root em) CSS unit. In CSS, rem refers to a scalable unit of measurement based on the font-size of the root <html> element. Unlike fixed pixels, rem units offer better scalability and ensure consistent font sizes and spacing throughout a design.

What is 1rem in CSS?

By default, most browsers set the root font-size to 16px, meaning 1rem = 16px. For example:

  • 2rem = 32px
  • 0.5rem = 8px

If you adjust the root font-size in your CSS (e.g., html { font-size: 18px; }), all rem values scale accordingly.

Why Use REM?

Using rem units improves:

  • Scalability: Easily adapt to different screen sizes or user preferences.
  • Consistency: Uniform spacing and font sizes across your UI.
  • Accessibility: Automatically respects user-defined browser font settings.
