...Work Sans is a 9-weight typeface family based loosely on early Grotesques — i.e. Stephenson Blake, Miller & Richard, and Bauerschen Giesserei. The core of the fonts are optimized for on-screen medium-sized text usage (14px-48px) – but still can be used in print well. The fonts at the extreme weights are designed more for display use. Overall, features are simplified and optimized for screen resolutions.
