A practical approach to structuring variables, nested components, and documentation in Figma to empower cross-functional teams.
A design system isn't just a UI kit; it is the official record of how a company's product should conceptually behave. Since Figma introduced Variables and Advanced Prototyping, the way we architect these systems has grown significantly more complex, mimicking software architecture.
Component Architecture
Base components (often heavily hidden via '_' prefixes) serve as the raw skeleton. Variant properties govern visual state configurations (Hover, Disabled, Error). By leaning heavily into boolean variables rather than variant spamming, designers can reduce Figma memory footprints by over 40%.
- Primitives: Base hex colors, raw absolute pixel sizing.
- Semantics: Colors mapped to intent (e.g., bg-danger, text-muted).
- Components: The actual UI elements mapping Semantics to geometry.
"The ultimate metric for a successful design system isn't how beautiful it looks, but how fast a junior developer can build a new feature without asking for clarification."
Documentation within the system must clearly define boundaries. Explaining when NOT to use a segmented control is arguably more important than explaining when to use one.
