Why it matters

The eye works hard to simplify. Give it simple shapes to begin with and icons, logos and layouts are recognised faster.

Rules to follow

  • Draw icons from simple geometric shapes with consistent stroke weights.
  • Avoid decoration that fights the silhouette: stacked gradients, heavy shadows, outlines on outlines.
  • Prefer clear, regular layouts over intricate ones.
