We took inspiration for F37 Jagger from Edward Johnston's London Underground font. The clean curved lines and simple form of this sans serif typeface takes on an accessible and unassuming quality. And that was precisely the outcome we wanted to achieve when we set out to develop F37 Jagger. Johnston’s contrast between the bulbous circular arcs and distinct straight edges in his letterforms is what inspired the shape and structure in F37 Jagger. The family's 8 fonts are a perfect marriage of clean lines with carefully considered spacing, and a little kick tail for good measure.
