Consistency and Standards

People should not have to wonder whether different words, situations or actions mean the same thing.

Why it matters

Consistency makes learning carry over from one screen to the next, and from other products to yours.

How to use it

  • Use one word for one thing.
  • Follow platform conventions.
  • Build from a shared design system.

Example

If some screens say "Sign in" and others "Log in", people may think they are different.
