Klein - 54 fonts
Klein is Zeta fonts love letter to the grandmother of all geometric sans typefaces, Future. Starting from a dialogue with Paul Renner's iconic letterforms and proportions, Francesco Canavero and Andrea Tartar Elli decided to depart from its distinctive modernist shapes with slight humanist touches and grotesque solutions - with some design choices evoking the softness of humanist sans serifs like Gill Sans.
The end result is a workhorse superfamily of 54 fonts with full multilingual capabilities and coverage of over two hundred languages using latin, cyrillic and Greek alphabets. The original display-oriented family, developed in nine weights with matching italics (from the hairline thin to the sturdy black), has been paired with a text version (with slightly higher x-height, better readability and maximum legibility at small point size)
