Rubik is a sans-serif typeface with slightly rounded corners, designed by Hubert & Fischer and expanded by Cyreal. Released in 2015, it offers a friendly, approachable character with excellent multi-script support.

History and Design

Hubert & Fischer originally designed Rubik as part of the Chrome Cube Lab project. Meir Sadan later expanded the family to include Hebrew support, and Cyreal added Cyrillic. The design features subtle rounded corners that soften the geometric foundation, creating a warm, friendly appearance without sacrificing professionalism.

Why Rubik is Popular

Rubik has become popular for its versatility and comprehensive language support. It serves as a free alternative to premium rounded sans-serifs like Circular and Proxima Nova. The Hebrew and Arabic support makes it particularly valuable for projects targeting Middle Eastern markets or requiring right-to-left languages.

Technical Features

  • Variable font: Weight axis from Light (300) to Black (900)
  • True italics: Carefully designed cursive forms
  • Multi-script support: Latin, Cyrillic, Hebrew, and Arabic
  • Rounded corners: Subtle softening of geometric forms
  • OpenType features: Tabular figures, case-sensitive forms

Best Use Cases

Rubik excels in:

  • App interfaces: Friendly, readable UI typography
  • Multilingual projects: Seamless across scripts
  • Tech branding: Modern, approachable identity
  • Documentation: Clear technical content
  • Corporate communications: Professional yet friendly

Usage Tips

For body text, use weight 400 at 16px with 1.5 line height. Use weight 500-600 for headings and 700-800 for display. The rounded corners become more apparent at larger sizes. Enable tabular figures for data-heavy interfaces. Pairs well with serif fonts for editorial contrast. The extensive language support makes it ideal for internationalized applications.
