A good Figma design system has several layers working together. Here's what each one actually does and why it matters.

Design tokens are the foundation. They're named values for visual decisions: colors, typography, spacing, border radii, shadows, motion. In Figma, you store these as Color Styles, Text Styles, Effect Styles, and Grid Styles. The newer Variables feature adds more flexibility, including semantic layering where a token like "surface/primary" maps to an underlying color value.

Component library. This is where most of the day-to-day work happens. Components are organized by complexity, starting with atoms like buttons, icons, and inputs, then molecules like search bars and form groups, then organisms like headers and data tables. Master Components define the source of truth, and Variants group related states and configurations so designers aren't juggling dozens of separate frames.

Auto Layout is what makes components actually behave in real-world conditions. When you build with Auto Layout, components resize based on their content, respecting padding, gaps, and stacking direction. Without it, your components are basically static screenshots.

Typography and iconography need their own systems too. A defined type scale using Text Styles keeps text consistent across screens. Your icon library should have consistent sizing, weight, and optical alignment, otherwise things look slightly off in ways that are hard to explain but easy to feel.

Documentation is where most design systems quietly fall apart. It's not enough to build great components; you need to explain when to use them, when not to, and why certain decisions were made. Do/don't examples, usage guidelines, and accessibility notes can live directly in the Figma file or link out to Storybook, Notion, or Zeroheight.

Library publishing lets teams share components and styles across the whole organization. Editors publish updates; consumers get notified to sync. It's a simple mechanism, but it's what keeps 20 product teams from quietly diverging over six months.

Governance is the part nobody wants to think about, but it determines whether
