EM to Pixel Calculator
This tool allows you to work out the PX size from EM sizes.
- Parent font size:
- px
- Size in EM:
- em
Result: 0 px.
With a parent font size of 16, the font size in pixels with an em of 0 is 0 px.
FAQs
What is the parent font size?
The parent font size is the font size of the parent container.
What is an EM?
An EM (Emphemeral Unit) is a unit of measurement relative to the font size of its parent. As such, when the parent font size changes, the size of the child font changes automatically.
For example:
- If the parent font size is 16 px and the child font is set to 1.5 EM, the child font is 16 x 1.5, or 24 pixels.
- If the parent font is changed to 20px, then the child font will automatically be 20 x 1.5, or 30 pixels.
How do you convert between EM and PX
You can use the calculator above to calculate the pixel size of a font from an EM value. Alternatively, here is the formula for EM to PX:
Formula: Size in EM * parent font size in pixels
Example: 2em * 16px = 32px
