Duolingo Font
Duolingo font is Feather Bold — a bespoke typeface designed exclusively for the brand, its rounded friendly shapes and playful bold weight perfectly calibrated for a language-learning platform that uses gamification, a green owl with surprisingly effective passive-aggression, and the quiet shame of a broken streak to keep 500 million people practicing Spanish.
Feather Bold is proprietary and not publicly available. Designers seeking a similar rounded, energetic sans-serif for personal projects can find a range of comparable open-source alternatives through Google Fonts — Nunito and Quicksand are strong starting points.
Find psychological thriller and blockbuster fonts like Free Fonts, Shutter Island Font, Inception Font, and Kpop Demon Hunters Font — and more.
