About
Designed by Leandro Assis and Álvaro Franca in 2017 and later expanded and reworked for open source by Henrique Baier, Gabarito takes its name from the Brazilian Portuguese word for an answer sheet. The typeface pairs a light-hearted geometric voice with a practical character set that includes circled numbers, fractions, superscripts, subscripts and a range of mathematical operators. Six weights from Regular to Black are available as both static fonts and a variable font, and the open source files are accessible via GitHub.
Classification
Gabarito is explicitly described as a geometric sans typeface, with rounded, friendly forms built on geometric construction principles suited to educational contexts.
