PX to EM Converter
Convert pixels to em units for component-relative sizing.
The em unit is relative to its parent's font size, which makes it the natural choice for padding, margins and components that should grow and shrink with their surroundings. This converter moves any pixel measurement to em and back against a base size you set.
em, rem — which and when?
- Lean on rem for your global type scale and em for component-relative spacing.
- Remember that em values compound through nested elements, so check deep nesting carefully.
- Match the base size to the element's own computed font size for an accurate result.
