A Sans Serif subgroup whose proportions and Stroke modulation derive from the Roman capital and Old Style Serif serif traditions, giving the letterforms a calligraphic warmth absent in Grotesque Sans Serif and Geometric Sans Serif designs. Humanist sans serifs exhibit visible stroke contrast, wide Aperture (improving Legibility), a double-story lowercase g, and a slight Axis / Stress on the vertical axis reminiscent of pen-drawn forms. Gill Sans (1928) is the prototypical example. The subgroup is prized for combining the clarity of sans serif construction with the organic readability of humanist letterform proportions.
