In typography, a font superfamily or typeface superfamily is a font family containing fonts that fall into multiple classifications. The norm in a superfamily is to start from an identical character shape; class-specific features such as serifs are added to that shape. The result is a set of fonts that, while belonging to different classes such as sans and serif, have a similar appearance. Generally the sans-serif member of a superfamily will be a humanist design to complement the serif. Other superfamilies may include fonts grouped together for a common purpose that are not exactly complementary in letterform structure.
