   What does a font size of 1 em mean?

   • By extension, a font-size of 1em equals the computed font-size of the element on which it is used. If a font-size has not been set on any of the 's ancestors, then 1em will equal the default browser font-size, which is usually 16px. So, by default 1em is equivalent to 16px, and 2em is equivalent to 32px.

   What does em mean in HTML?

   • The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion.

   What is em in digital fonts?

   • In metal type, the point size (and hence the em, from em quadrat) was equal to the line height of the metal body from which the letter rises. In metal type, the physical size of a letter could not normally exceed the em. A digital font's design space in digital type is called the em, which is a grid with arbitrary resolution.

   Dec 14, 2021 · There are now lots of sources which say that 1em = font size (in px). That is, when you write font-size:16px, then 1em = 16px. This still doesn't agree with the Adobe source (which says 1em = the font size in pt), but in either case it seems bizarre; the em size would be far too large with condensed fonts and far too small with extended fonts.

   • em, px, pt, cm, in… CSS offers a number of different units for expressing length. Some have their history in typography, such as point (pt) and pica (pc), others are known from everyday use, such as centimeter (cm) and inch (in).
   • Use em or px for font sizes. CSS inherited the units pt(point) and pc(pica) from typography. Printers have traditionally used those and similar units in preference to cmor in.
   • More units in CSS. To make it even easier to write style rules that depend only on the default font size, CSS has since 2013 a new unit: the rem. The rem(for “root em”) is the font size of the root element of the document.
