Design Nomenclature / Type
Stress
Also called axis, shading
- Type
- 2D
The angle of the line joining the thinnest points of a round stroke — a fossil of the broad-nibbed pen's angle. Humanist and garalde faces have it inclined to the left; transitionals bring it near vertical; didones make it exactly vertical. Most sans faces have no meaningful stress at all, being close to monoline.
In practice
Called "axis" as often as stress, which collides with the variable-font sense of axis and with the geometric one. Say stress when you mean the letterform.
