Consistency in an interface

Consistency means similar things look and work the same way on every screen, like buttons with the same style and a menu in the same place, so users always know what to do.

Understanding Consistency in an interface in Years 5–6 Creating Digital Solutions

What it does: Both screens show the Next button with the same colour, shape and label, which is a consistent button style. Consistency means the same kind of button looks the same on every screen, so users know what to click. The Back button moves, so players might not find it. It should stay in the same place. When things look and work the same, users feel confident and make fewer mistakes. Consistency is the core idea: matching looks and behaviour across all screens makes an interface easy to learn and use.

Common mistakes: The Next button looks different on the Score screen. For consistency it should be blue and round like the other screens, so users recognise it. The menu on the Quiz screen is in a different place. It should be at the top left, the same as on every other screen.

Spot the Error

Question 1
A Home: Next is blue, round

Line B — The menu on the Quiz screen is in a different place. It should be at the top left, the same as on every other screen.
Question 3
A Style: all buttons are blue
