PX to EM Conversion

PX to EM Converter

  • Set a default font size (usually 16px)
  • Then, convert a pixel value to em, based on the default size
  • Or, convert an em value to pixels, based on the default size

Body Font Size

In the table below, select a body font size in pixels (px) to display a complete "px to em and percent" conversion table.

Pixel is a static measurement, while percent and EM are relative measurements. The size of an EM or percent depends on its parent. If the text size of body is 16 pixels, then 150% or 1.5 EM will be 24 pixels (1.5 * 16).

The reason headings often use em units is they're a better choice than px units, being relative to regular text size. However rem units can achieve this goal equally well. If any font size adjustment on the html element is made, the heading sizes will still scale too.
