Strava — Design System

Strava trains in its custom Boathouse face at app-honest sizes (14-32px/600), athlete photography full-bleed, and 4px-radius signup cards. Segment maps and kudos feeds carry the energy — the social network for sweat keeps its type compact because the athletes' numbers are the display face.

Strava's decoded design system: background #FFFFFF, text #000000, accent #FC5200, link #0060D0, primary #FC5200; type scale h1 32px / h2 14px / body 15px; 8px spacing base; 0px base radius.

Color roles

Using these colors

• Action color #FC5200 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #FC5200 — one role, not several (the action color).
• accent #FC5200 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• link #0060D0 — inline text links and link-styled controls.

# Strava — Design System

> light, modern, high, custom

Strava trains in its custom Boathouse face at app-honest sizes (14-32px/600), athlete photography full-bleed, and 4px-radius signup cards. Segment maps and kudos feeds carry the energy — the social network for sweat keeps its type compact because the athletes' numbers are the display face.
