I released Scheme on March 27, 2008. The inspiration came not from typewritten text itself but from the lettering on typewriter keycaps, and later on early computer keyboards. Those rounded sans-serif technical forms had a utilitarian quality I wanted to capture. To soften it, I gave the lowercase letters a more playful feel, with some curls and bounce in the strokes. The result was a contrast between uppercase characters that carried the mechanical, vintage look and lowercase forms that made the typeface more approachable. At release, Scheme included four weights: Light, Book, Regular, and Bold.

It was always a paid typeface. In early 2009, I expanded the character set to cover extended Latin. On July 3, 2022, I issued a larger update that added italics, improved the balance of fractions, superiors, and inferiors, and enhanced the OpenType fractions feature to handle longer numerators and denominators. In November 2024, I reorganized the weights so Book became Light and Light was renamed Extra-Light, clarifying the family’s progression.

Scheme has not been adopted in any notable contexts that I know of, but I’ve kept it in my library as a typeface that balances technical inspiration with a friendlier lowercase design.
