Core Workflows

Workflow 1: Font Pairing Selection

1. Understand project context:
   • Medium (web, print, mobile, presentation)
   • Brand personality (modern, classic, playful, serious)
   • Content type (long-form, UI labels, marketing, technical)
   • Audience demographics
2. Recommend font pairs:
   • Heading font (display/serif/sans)
   • Body font (optimized for readability)
   • Optional: Accent/code font
3. Provide pairing rationale:
   • Why these fonts work together
   • Contrast principles applied
   • Mood and personality match
4. Show examples with actual content
5. Include fallback stacks and loading strategy

Workflow 2: Type Scale Creation

1. Define base settings:
   • Base font size (typically 16px for web)
   • Scale ratio (1.125, 1.25, 1.333, 1.5, etc.)
   • Viewport ranges (mobile, tablet, desktop)
2. Generate type scale:
   • 6-8 hierarchical sizes
   • Calculate line heights
   • Set letter spacing
   • Define font weights
3. Map to semantic elements:
   • H1-H6 headings
   • Body, small, caption
   • Button, label, code
4. Create responsive variations
5. Export as CSS/Tailwind config

Workflow 3: Typography System Audit

1. Analyze existing typography:
   • Inventory all font sizes, weights, families
   • Check consistency across pages
   • Measure readability metrics
2. Identify issues:
   • Too many sizes (inconsistency)
   • Poor contrast/readability
   • Weak hierarchy
   • Accessibility problems
3. Provide recommendations:
   • Consolidate to systematic scale
   • Improve legibility
   • Strengthen visual hierarchy
4. Create migration guide

Workflow 4: Readability Optimization

1. Assess content requirements:
   • Reading context (skimming vs. deep reading)
   • Content length
   • User constraints (age, vision, mobile usage)
2. Optimize parameters:
   • Line length (45-75 characters ideal)
   • Line height (1.5-1.75 for body text)
   • Font size (minimum 16px for body)
   • Contrast (minimum 4.5:1 for normal text)
3. Test with real content
4. Provide device-specific adjustments

Quick Reference

| Action | Command/Trigger | |--------|-----------------| | Find font pairs | "Suggest fonts for [brand/project]" | | Create type scale | "Build a typography system for [context]" | | Audit existing | "Review my typography for issues" | | Optimize readability | "Make this text more readable" | | Get Google Fonts | "Recommend free fonts for [use case]" | | Premium options | "Suggest premium fonts for [project]" |

Font Pairing Principles

Contrast is key: Pair different styles (serif + sans, geometric + humanist)

Limit to 2-3 fonts: More creates chaos

• Heading font (personality)
• Body font (readability)
• Optional accent (code, callouts)

Superfamilies work: Fonts designed together (like IBM Plex, Work Sans, etc.)

Consider x-height: Fonts with similar x-heights pair better

Match mood: Both fonts should support the brand personality

Test in context: View fonts with actual content, not lorem ipsum

Type Scale Ratios

| Ratio | Name | Best For | |-------|------|----------| | 1.067 | Minor Second | Subtle, minimal contrast | | 1.125 | Major Second | Conservative, professional | | 1.200 | Minor Third | Balanced, versatile | | 1.250 | Major Third | Clear hierarchy, most common | | 1.333 | Perfect Fourth | Strong hierarchy | | 1.414 | Augmented Fourth | Bold, editorial | | 1.500 | Perfect Fifth | Dramatic, luxury | | 1.618 | Golden Ratio | Harmonious, natural |

Best Practices

• Mobile first: Ensure fonts are readable at small sizes
• Performance matters: Limit font weights and styles loaded (2-4 max)
• Use variable fonts: One file, infinite weights (modern browsers)
• System fonts as fallbacks: Always provide -apple-system, BlinkMacSystemFont, etc.
• FOIT/FOUT strategy: Use font-display: swap for better UX
• Subset fonts: Only load characters you need (Latin, numerals, etc.)
• Line length matters: 45-75 characters per line for readability
• Hierarchy first: Size differences should be obvious at a glance
• Consistent spacing: Use the type scale for margins and padding too
• Test with real content: Lorem ipsum hides readability issues
• Accessibility: Minimum 16px body, 4.5:1 contrast, avoid light weights for small text
• Respect user settings: Don't break zoom, respect reduced motion
• Version control: Document font versions when using commercial fonts
