font-size

The font-size attribute refers to the size of the font from baseline to baseline when multiple lines of text are set solid in a multiline layout environment. For SVG, if a <length> is provided without a unit identifier (e.g., an unqualified number such as 128), the browser processes the <length> as a height value in the current user coordinate system.

If a <length> is provided with one of the unit identifiers (e.g., 12pt or 10%), then the browser converts the <length> into a corresponding value in the current user coordinate system

As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet, see css font-size for further information.
