Algebra evolved from Granger, a headline typeface designed by Susana Carvalho and Kai Bernau for the US edition of Esquire in 2010. Algebra is a broad-shouldered slab serif typeface built on superelliptical forms. Its loose spacing gives a remarkably comfortable texture in text, and its crisp detailing gives a distinctive and serious feeling at display sizes, particularly with some negative tracking. Algebra references Adrian Frutiger’s Egyptienne, Georg Trump’s Schadow, and Hermann Zapf’s Melior, but its clean lines make it appropriate for contemporary use in modern magazine design. The flat vertices where diagonals intersect (as in the A or M) give a brutal feeling, playing nicely off of the bulky round shapes. Functionally, the flat vertices keep the letters from clogging even at text sizes on screen and under the worst printing conditions.
