ex has less support than em, go with em if you are considering either.

In addition to what jongund mentioned, although em and ex relate to heights,
you can use either to specify widths as well such as margin-left: 1em or
width: 30ex.

Dagmar,

em is the height of the current uppercase font being rendered
ex is the height of the current lowercase font being rendered

So these provide spacing based on the current font height of
the element being styled with CSS.
