Ortodoxa by Monograma.
‘Orthodox’ means following or conforming to the traditional or generally accepted rules or beliefs of a practice. That is the same principle of Ortodoxa, a typeface that holds to the tradition of sans-serif without the aim of innovation but rather seeks for a fresh look at conventional letterforms. Inspired by modern geometric typography, this versatile family stands for cleanness, neutrality and, most important, legibility. It is well-suited for paper or computer screens.
