Pan-Cyrillic font superfamily PT Sans – PT Serif developed for the project “Public Types of Russian Federation”.
Font families PT Sans and PT Serif were released in 2009–2010 with open user license. The main aim of the project is to give possibility to the peoples of Russia to read and write on their native languages. The project is dedicated to 300-year anniversary of the civil type invented by Peter the Great in 1708–1710 years and was realized with financial support from Federal Agency for Press and Mass Communications.
PT Serif is a transitional serif face with humanistic terminals designed for use together with PT Sans and harmonized with PT Sans on metrics, proportions, weights and design. PT Serif consists of six styles: regular and bold weights with corresponding italics form a standard computer font family for basic text setting; two caption styles (regular and italic) are for texts of small point sizes.
