Common Sans has its origins in the Caslon Two Lines Egyptian (c:a 1816), which only has capital letterforms. Edward Johnston’s 1913 typeface for the London Underground was a key to designing a lowercase set. The Toronto subway typeface (c:a 1954) – an American Futura clone – was the other inspiration.
Certain letters deviated from their strict ancestors, borrowing shapes from my own handwriting.
It is a clear, iconic typeface in one weight. Future releases include light, bold and respective true italic fonts. Aimed at headings and larger sizes, but also suitable for website and app body text.
