What fonts go with Rubik? This geometric sans-serif with its signature rounded corners brings friendly approachability that demands companions capable of matching its warm personality while providing meaningful variety.
Rubik was designed by Philipp Hubert and Sebastian Fischer of Hubert & Fischer, originally commissioned by Google for a Rubik’s Cube exhibition—hence the playful name. The design features stout proportions with rounded corners and low stroke contrast that give it both warmth and stability. Those soft edges make Rubik instantly recognizable and distinctly approachable, while the seven weights with matching italics provide remarkable flexibility for interface and branding work.
