FF Sero combines the striking forms of an American Grotesque with the legibility of a Humanist Sans Serif typeface. It has open contours, a distinct x-height and a homogeneous grey scale value. During the seven years of development the classic letterforms have matured and transformed into a balanced, sovereign typeface. Eight harmonized weights and an extensive character set allow for a flexible and versatile typography and Cyrillic and Greek characters provide extended language support.
