Introduction to Figma Variables {#introduction}

Figma Variables represent a paradigm shift in how designers approach scalable, systematic design. Released as a game-changing feature, variables enable designers to create dynamic, maintainable design systems that adapt across different contexts, themes, and platforms with unprecedented efficiency.

Variables in Figma are reusable values that can be applied to various design properties throughout your files. Think of them as the DNA of your design system—they carry the essential information that defines your brand’s visual identity and can be modified once to update everywhere they’re applied.

Why Variables Matter

Consistency at Scale: Variables ensure that your design maintains visual consistency across hundreds or thousands of components and screens.

Efficiency: Update a color, spacing value, or typography scale once, and see it propagate throughout your entire design system instantly.

Collaboration: Variables create a shared language between designers and developers, making handoff smoother and implementation more accurate.

Adaptability: Easily create themes, responsive designs, and platform-specific variations without duplicating work.

Understanding Variable Types {#variable-types}

Figma supports four distinct types of variables, each serving specific design needs:

1. Color Variables

Color variables are the foundation of any cohesive visual system. They go beyond simple color storage to enable sophisticated theming and accessibility features.

Primary Applications:

Brand colors (primary, secondary, accent)
Semantic colors (success, warning, error, info)
Neutral scales (grays, backgrounds, borders)
Text colors with proper contrast ratios

Advanced Color Strategy: Create semantic color variables that reference base colors. For example:

color/base/blue/500 (base color)
color/semantic/primary (references blue/500)
color/component/button-primary (references semantic/primary)

This three-tiered approach provides maximum flexibility while maintaining clear relationships between colors.

2. Number Variables

Number variables control quantitative aspects of your design, from spacing to sizing, border radius to opacity values.

Common Use Cases:

Spacing scales (4px, 8px, 16px, 24px, 32px…)
Typography scales (12px, 14px, 16px, 20px, 24px…)
Border radius values
Opacity levels
Shadow blur amounts
Animation durations

Creating Systematic Scales: Use mathematical relationships to create predictable scales. Popular approaches include:

Linear scales (multiples of 4 or 8)
Modular scales (based on ratios like 1.25 or 1.618)
Fibonacci sequences for organic progression

3. String Variables

String variables manage textual content that appears consistently across your design system.

Strategic Applications:

Component labels and microcopy
Error messages and validation text
Placeholder text
Button labels
Navigation items

Content Strategy Benefits: String variables enable content designers to maintain consistency and facilitate localization efforts by centralizing all text content.

4. Boolean Variables

Boolean variables control binary states and conditional visibility of design elements.

Powerful Use Cases:

Feature flags for A/B testing
Component state management
Conditional content display
Responsive design toggles
Accessibility options

Creating and Managing Variables {#creating-managing}

Setting Up Your First Variables

Step 1: Access the Variables Panel Navigate to the Local Variables panel in your Figma file. This becomes your command center for all variable management.

Step 2: Create Variable Collections Organize variables into logical collections before creating individual variables. This structure will pay dividends as your system grows.

Step 3: Establish Naming Conventions Early Consistent naming is crucial for long-term maintainability. Consider these approaches:

Hierarchical Naming:

spacing/xs (4px)
spacing/sm (8px)
spacing/md (16px)
spacing/lg (24px)
spacing/xl (32px)

color/brand/primary
color/brand/secondary
color/semantic/success
color/semantic/warning

BEM-Inspired Naming:

button--primary--background
button--primary--text
button--secondary--background
button--secondary--text

Variable Scoping and Aliases

Creating Aliases Variables can reference other variables, creating powerful dependency chains. Use this to:

Create semantic meanings from base values
Enable easy theme switching
Maintain relationships between related values

Scoping Strategy Consider how variables should be scoped:

Global scope: Available across all files
File scope: Specific to particular projects
Component scope: Only relevant to specific components

Collections and Modes {#collections-modes}

Collections and modes are where Figma Variables truly shine, enabling sophisticated multi-state design systems.

Understanding Collections

Collections are groups of related variables that share the same modes. Think of them as categories that help organize your design tokens logically.

Effective Collection Strategies:

By Property Type:

Colors Collection
Spacing Collection
Typography Collection
Elevation Collection

By Context:

Brand Collection
Component Collection
Layout Collection
Content Collection

Mastering Modes

Modes enable variables within a collection to have different values depending on context. This is revolutionary for creating adaptive design systems.

Essential Mode Applications:

Theme Modes:

Light Mode
Dark Mode
High Contrast Mode
Brand Variant Modes

Platform Modes:

Desktop
Mobile
Tablet

State Modes:

Default
Hover
Active
Disabled

Advanced Mode Strategies

Responsive Design with Modes: Create breakpoint modes that automatically adjust spacing, typography, and layout properties based on screen size.

Accessibility Modes: Design modes that enhance accessibility, such as:

High contrast color palettes
Larger text sizes
Increased spacing for easier touch targets

A/B Testing Modes: Use modes to create variations for testing different design approaches without duplicating components.

Advanced Implementation Strategies {#advanced-strategies}

Variable Architecture Patterns

The Token Hierarchy Approach: Structure variables in three tiers:

Foundation Tokens: Raw values (colors, spacing units)
Semantic Tokens: Purpose-driven aliases (primary, secondary)
Component Tokens: Context-specific applications (button-primary-background)

The Atomic Design Integration: Align variables with atomic design principles:

Atoms: Base variables (colors, spacing)
Molecules: Component-specific variables
Organisms: Layout and section variables
Templates: Page-level variables

Complex Variable Relationships

Mathematical Relationships: Use number variables to create mathematical relationships. For example:

spacing-base = 16px
spacing-half = spacing-base * 0.5
spacing-double = spacing-base * 2

Conditional Logic with Booleans: Combine boolean variables with other variable types to create sophisticated conditional designs.

Performance Optimization

Variable Loading Strategy: Structure variables to minimize performance impact:

Keep frequently changing variables separate from stable ones
Use local variables for file-specific needs
Leverage shared libraries for system-wide variables

Design System Integration {#design-system}

Building Variable-First Components

Component Architecture: Design components that are built around variables from the ground up. Every property that might need to change should reference a variable.

Variant Strategy: Use component variants in combination with variable modes to create powerful, flexible component systems.

Documentation Integration: Variables should be documented alongside components, explaining not just what they control but why they exist and how they should be used.

Library Management

Publishing Strategy: Establish clear processes for publishing variable updates:

Version control for variable changes
Change logs for variable modifications
Testing procedures before publishing updates

Consumer Guidelines: Create clear guidelines for teams consuming your variable library:

When to use existing variables vs. creating new ones
Naming conventions for custom variables
Approval processes for variable additions

Cross-Platform Considerations

Token Translation: Plan how variables will translate to development tokens:

CSS custom properties
Design tokens (JSON/YAML)
Platform-specific formats (iOS, Android)

Naming Alignment: Ensure variable names align with development conventions to smooth the design-to-code handoff.

Collaboration and Handoff {#collaboration}

Developer Collaboration

Shared Understanding: Variables create a shared vocabulary between design and development teams. Establish clear documentation that explains:

Variable purposes and contexts
Expected behaviors across different states
Implementation guidelines

Design Token Integration: Variables should map directly to design tokens used in development:

Use consistent naming conventions
Document variable hierarchies
Provide usage examples

Design Team Workflows

Variable Governance: Establish processes for variable management:

Who can create new variables
Review processes for variable changes
Documentation requirements

Education and Onboarding: Create resources to help team members understand and use variables effectively:

Variable style guides
Best practice documentation
Training materials

Best Practices and Common Pitfalls {#best-practices}

Essential Best Practices

Start Simple, Scale Thoughtfully: Begin with a small set of well-considered variables rather than trying to systematize everything at once. Add complexity gradually as needs become clear.

Naming is Critical: Invest time in creating clear, consistent naming conventions. Names should be:

Descriptive and intuitive
Consistent across all variables
Future-proof and scalable

Document Everything: Every variable should have clear documentation explaining:

Its purpose and intended use
Relationships to other variables
Any constraints or considerations

Test Thoroughly: Before publishing variable changes:

Test across all affected components
Verify behavior in all modes
Check for unintended consequences

Common Pitfalls to Avoid

Over-Variabilizing: Not everything needs to be a variable. Focus on values that:

Are used in multiple places
Might need to change
Have semantic meaning

Inconsistent Naming: Mixed naming conventions create confusion and reduce adoption. Establish conventions early and stick to them.

Poor Organization: Disorganized variables become unmaintainable quickly. Group related variables and use clear hierarchies.
