The curved Stroke that encloses a closed Counter in a letterform. Bowls are prominent in letters such as b, d, p, q, and the upper and lower loops of B. The shape, tension, and symmetry of a bowl — whether it is round, oval, or squared — are defining features of a Typeface personality and contribute directly to its classification: Geometric Sans Serif sans serifs favor near-circular bowls, while Humanist Sans Serif designs tend toward more organic, asymmetric forms.
