Usage Patterns

Most Common Patterns:

1. Gap utilities (1,314 instances) - Used for flexbox/grid layouts
2. Padding utilities (1,041 instances) - Used for component internal spacing
3. Padding X/Y utilities (784 instances) - Used for directional padding
4. Space between utilities (611 instances) - Used for spacing between children
5. Margin utilities (217 instances) - Used for external spacing and centering

Size Distribution:

• Small spacing (1-2): ~1,200 instances (43%) - 4px-8px
• Medium spacing (3-4): ~1,000 instances (36%) - 12px-16px
• Large spacing (6-8): ~400 instances (14%) - 24px-32px
• Extra large spacing (10+): ~160 instances (6%) - 40px+

Inconsistencies Identified

1. No semantic spacing classes: All spacing uses numeric values (0, 1, 2, 3, 4, etc.) instead of semantic names (xs, sm, md, lg, xl)
2. Inconsistent spacing values: Similar contexts use different spacing values
3. Arbitrary values: Some rare spacing values (5, 7, 9, 10, 11, 20, 24, 48) that don't follow the 4px base scale
4. Mixed patterns: Some components use gap-, others use space-y- for similar purposes

Recommendations

Standardization Strategy:

1. Map numeric to semantic:

   • 1 → xs (4px)
   • 2 → sm (8px)
   • 3 → md (12px) - or keep as numeric
   • 4 → md (16px) - base spacing
   • 6 → lg (24px)
   • 8 → xl (32px)
   • 12 → 2xl (48px)
   • 16 → 3xl (64px)
   • 20 → 4xl (80px)
   • 24 → 5xl or xxl (96px)

2. Preserve common patterns: Keep most common values (gap-2, p-4, space-y-4) as they represent good defaults

3. Standardize rare values: Replace arbitrary values (5, 7, 9, 10, 11) with nearest scale value

4. Create migration guide: Document which numeric values map to which semantic values

Files Requiring Attention

• 366 files contain spacing classes
• Top files by spacing usage:
  • Components with complex layouts (DashboardPage, LibraryPage, etc.)
  • Form components (RegisterForm, LoginForm, etc.)
  • Modal components (various modals)
  • View components (ProfileView, SettingsView, etc.)

Next Steps

1. ✅ Action 7.2.1.2 Complete: Audit complete
2. Action 7.2.1.3: Replace inconsistent spacing with scale
3. Action 7.2.1.4: Add ESLint rule to enforce spacing scale

Conclusion

The audit reveals extensive use of numeric spacing classes (2,761 instances across 366 files):

• Most common: gap-2 (519), p-4 (357), gap-4 (299)
• All spacing uses numeric values (0-48), no semantic names found
• Good distribution across spacing sizes (small to extra large)
• Some inconsistencies with arbitrary values that should be standardized

Recommendation: Standardize spacing incrementally, starting with the most common patterns and rare/arbitrary values.
