Flare Axis (FLAR)

The Flare axis is a variable font setting that controls how much a stroke widens from its main stem toward its ends. At its lowest setting, strokes stay uniform and monolinear; the highest adds dramatic contrast, especially visible in bolder weights.

A tall pink vertical rule at the left marks two rows of blue stems demonstrating a flare axis: the upper stems in Nexa end flat and parallel, while the lower stems in Gwen widen into flared, trumpet-shaped terminals at top and bottom.

The Flare axis (represented by the uppercase CSS attribute FLAR) is a variable font setting that gives designers control over the transition and widening of stroke widths from their main vertical stems out to their terminal ends. At its lowest setting, the typeface maintains uniform, monolinear stroke weights throughout the character architecture. Conversely, adjusting the setting to its highest point introduces a pronounced contrast and terminal expansion to the letterforms, creating a visual styling that becomes significantly more apparent and dramatic when applied to bolder typographical weights.
