Stratum
Process Type Foundry · Eric Olson, with Egor Golovyrin and Maria Doreuli (Cyrillic), and George Triantafyllakos (Greek) · 2004
A geometric sans-serif by Eric Olson, first released in 2004 and substantially updated in 2024 with italics and expanded script support, now a fixture in sports branding and interface design worldwide.
About
Offered in two variants, Stratum 1 with sharp angled terminations and Stratum 2 with flat terminations, the family spans six weights across 24 styles including the long-awaited italics added in the 2024 revision. Cyrillic and Greek are now standard, with localised forms for Bulgarian, Serbian and Macedonian, alongside tabular figures and extended currency symbols. Two decades of deployment across global brands, sports franchises and video game titles speak to its durability as a geometric workhorse.
Classification
Stratum is a geometric sans-serif with two distinct terminal treatments: sharp angled (Stratum 1) and flat (Stratum 2), both rooted in geometric construction suited to technical and branding applications.
