Rubik + Karla — Friendly Startup Typography

Rubik + Karla for Startup Websites

This pairing strikes the balance between friendly and professional that most startups need. Both fonts are clean and modern, but their subtle personality differences create effective visual hierarchy.

Rubik: Rounded and Approachable

Rubik is a sans-serif with slightly rounded corners, giving it a friendly, approachable character without veering into childish territory. At bold weights, it communicates confidence and energy.

h1, h2, h3 {
  font-family: 'Rubik', system-ui, -apple-system, sans-serif;
  font-weight: 700;
}

Karla: The Understated Partner

Designed by Jonathan Pinhorn, Karla is a grotesque sans-serif that stays out of the way. Its clean, slightly narrow letterforms are ideal for body text, navigation, buttons, and form labels.

body {
  font-family: 'Karla', system-ui, -apple-system, sans-serif;
  font-weight: 400;
  line-height: 1.6;
}

Startup Design Tips

For startup landing pages, use Rubik at extra-bold (800) for the hero headline, bold (700) for section headings, and Karla at regular (400) for everything else. Both fonts support extensive character sets, making them suitable for multilingual products.
