Fira SansRoboto
The honest take
Two mobile-born humanist-leaning sans faces from opposite ecosystems. Fira Sans (Erik Spiekermann & Carrois Apostrophe, 2013) was commissioned by Mozilla for Firefox OS: a genuinely humanist sans with a warm, readable character, real detail in its letterforms and a broad 300–700 range that makes it excellent for both UI and running text. Roboto (Christian Robertson, 2011) is Android's more mechanical grotesque, tighter and more systematic, softened by friendly curves. Choose Fira Sans when you want warmth and craftsmanship — Spiekermann's hand shows — and a face that feels less anonymous in body copy. Choose Roboto for maximum familiarity, the Android look, and the safest neutral default. Fira Sans is the more distinctive read; Roboto the more invisible one.
The x-ray
Same size, same baseline — Fira Sans over Roboto. Where they agree the strokes merge; where they argue, fringes.
“Hamburgefonstiv” is the type designer's test word — it carries most of the shapes that give a face away.
