Icon Usage Best Practices

Choose One Library

Stick to one icon library per project for consistency and to reduce file size. Mixing libraries leads to bloat.

Size Appropriately

Use consistent icon sizes throughout your design. Common sizes: 16px, 24px, 32px, 48px.

Add ARIA Labels

Always include aria-label or aria-hidden attributes for accessibility when icons are used alone.

SVG vs Icon Fonts

Use SVG for better accessibility and flexibility. Icon fonts are simpler but have accessibility limitations.

Optimize SVGs

Run SVG icons through SVGO or similar tools to reduce file size by removing unnecessary metadata.

Use Icon Sprites

For multiple SVG icons, use sprite sheets to reduce HTTP requests and improve performance.
