Zero to minimal border radius for a crisp, architectural look. Straight edges create a strong, professional aesthetic perfect for fintech, enterprise tools, and brutalist designs.
Use the Sharp Geometric radius system for a crisp, architectural UI. Border radii: none (0px) for containers and sections, 2px for buttons and inputs, 4px for cards and modals. Avoid rounded corners — this system uses sharp edges to convey precision and authority. Apply 2px radius to interactive elements only for subtle softening. Never use border-radius greater than 4px with this system.
