Building Design Systems That Scale

A design system isn’t a Figma file with components. It’s a living agreement between design and engineering about how products should be built.

The Architecture

Tokens are the foundation. Colors, spacing, typography scales, radii, shadows: these are your primitives. Everything else is composed from them.

Primitives are simple components. Buttons, inputs, badges. They map directly to HTML elements and are consumed by patterns.

Patterns solve recurring problems. Form layouts, data tables, empty states. These are where design system maturity really shows.

Product components are custom. Not everything belongs in the system. Your unique product features should be built on top of the system, not inside it.

What I’ve Learned

The biggest mistake teams make is over-building the system before anyone uses it. Start with what hurts the most. If everyone is building their own button, start there.

The best design system I’ve ever worked on started with three tokens and a button. Everything else grew from actual need, not hypothetical completeness.
