Consistency and standards

Consistency and standards

Things that do the same job should look and work the same way. In the "Mixed patterns" settings, one setting uses a toggle and the other a checkbox, and the icons and arrows sit in different places.

The "Familiar patterns" version uses a toggle for both on/off settings and places the icons, labels and arrows consistently. People learn the pattern once and reuse it.

Two kinds of consistency matter:

  • Internal: the same patterns across your own product.
  • External: following the conventions people know from other products and platforms.
