Consistency is a fundamental UX principle that allows users to learn and use your product more quickly.
As Jakob Nielsen stated: 'Users expect different parts of the system to work in similar ways.'
4 Core Consistency Types:
- Visual Consistency
- Color palette, typography, iconography, spacing
- Consistent grid system and alignment
- Size proportions of elements
- Functional Consistency
- Similar operations working in similar ways
- Menu structures, navigation models
- Interaction patterns (swipe, drag, tap)
- Content Consistency
- Tone and style
- Terminology and labeling
- Message hierarchy
- External Consistency
- Compliance with platform conventions (iOS/Android)
- Compliance with industry standards
- Alignment with user expectations
Ways to ensure consistency:
- Create a design system and style guide
- Use a component library
- Conduct regular design reviews
- Monitor user feedback
A consistent interface reduces the user's mental load and builds trust.
