PX to REM Converter: Simplify Your CSS Calculations

Converting pixels (PX) to rems (REM) is a common task when working with responsive web design. By using relative units like REM, you can create more flexible, scalable layouts that adapt to different screen sizes. If you're tired of manually calculating these conversions, our PX to REM Converter tool is here to help.

What is PX and REM?

  • PX (Pixel): A fixed unit of measurement that refers to a single dot on the screen. It is widely used in web design for pixel-perfect layouts, but it doesn’t scale well with different screen sizes and resolutions.

  • REM (Root Em): A relative unit of measurement based on the root element’s font size (typically the <html> tag). One REM is equal to the font size of the root element, making REMs more flexible for responsive design.

The Formula for Converting PX to REM

To convert PX to REM, you can use this formula:

REM = PX ÷ Root font size

By default, most browsers set the root font size to 16px. This means that if the root font size is 16px, 1 REM will equal 16px. If the root font size is different, you'll need to adjust the calculation accordingly.

How the PX to REM Conversion Tool Works

Our PX to REM Converter automatically handles the math for you. Simply input the pixel value (PX), and the tool will output the corresponding REM value based on the current root font size.

For example:

  • If the root font size is 16px, 32px will be converted to 2 REM.
  • If the root font size is 18px, 32px will be converted to 1.78 REM.

Example Conversion Table

Here’s a conversion table to help you visualize how PX values convert to REM based on different root font sizes.

PX Value Root Font Size 16px Root Font Size 18px Root Font Size 20px
8px 0.5 REM 0.44 REM 0.4 REM
16px 1 REM 0.89 REM 0.8 REM
32px 2 REM 1.78 REM 1.6 REM
48px 3 REM 2.67 REM 2.4 REM
64px 4 REM 3.56 REM 3.2 REM
128px 8 REM 7.11 REM 6.4 REM

Why Use REM Instead of PX?

  • Scalability: REMs are relative to the root font size, making them scalable across different devices and screen sizes.
  • Accessibility: Using REMs helps users who may have adjusted their browser’s default font size for readability.
  • Consistency: REMs provide a more consistent and predictable layout, especially when working with multiple screen resolutions.

Why Use the PX to REM Converter?

  • Accuracy: Avoid errors and manual calculation.
  • Convenience: Save time by quickly converting PX values to REM.
  • Flexibility: Adjust the root font size for your specific project needs.
