Mediator Serif is a balanced contemporary serif typeface that performs well both in display sizes (like in packaging or branding) and body text (books or periodicals where narrow styles will be extremely useful). Mediator Serif is a complementary serif face for Mediator Sans. The family contains 32 fonts in 2 widths: 8 romans with matching italics, of slightly extended proportions, from Thin to Black; and 8 narrow styles with matching italics too. The character set in all faces was expanded to include small caps and old style figures. The typeface was designed by Manvel Shmavonyan with the participation of Alexander Lubovenko and released by ParaType in 2017.
