Should you use em for font size?
Use em only for sizing that needs to scale based on the font size of an element other than the html (root) element. Use rem unit for elements that scale depending on a user’s browser font size settings. Use rem as the unit for most of your property value. For complex layout arrangement, use percentage (%).
How do I set base font size in em?
If you haven’t set the font size anywhere on the page, then it is the browser default, which is probably 16px. So, by default 1em = 16px , and 2em = 32px . If you set a font-size of 20px on the body element, then 1em = 20px and 2em = 40px . Note that the value 2 is essentially a multiplier of the current em size.
