Rubik
Rubik was designed by Hubert and Fischer for the Chrome Cube Lab project, featuring subtly rounded corners on each letterform that give it a distinctive, friendly personality without sacrificing professionalism. Its geometric structure with humanist touches makes it exceptionally well-suited for mobile apps, tech products, and UI interfaces where warmth and clarity need to coexist. As a variable font supporting Latin, Cyrillic, and Hebrew scripts, it offers broad multilingual coverage alongside its full weight range from Light to Black.

Frequently Asked Questions
What is the Chrome Cube Lab project that Rubik was designed for?
Chrome Cube Lab was a Google Chrome experiment that let users interact with a virtual Rubik's Cube. The font was commissioned for the project's interface, taking its name and rounded-corner aesthetic from the iconic puzzle cube.
How do Rubik's rounded corners differ from fully rounded fonts like Nunito?
Unlike Nunito, which has fully rounded terminals, Rubik applies subtle rounding only to the corners of each letterform's bounding shape. This creates a softer feel than sharp-cornered fonts without the overtly playful quality of fully rounded terminals.
Why is Rubik a strong choice for mobile app interfaces?
Rubik's rounded corners feel native to mobile design language where rounded UI elements are standard. Combined with its generous x-height, clear letterforms, and full variable weight range, it reads well at the small sizes and touch-target constraints typical of mobile screens.
