Introduction
Tooltips are the smallest, least intrusive UI element for contextual education—a brief hint that appears exactly when and where a user needs it. This guide covers use cases, design patterns, and placement rules for effective tooltips.
Tooltip Use Cases
- Explaining an icon-only button's function
- Clarifying a metric or data point ("What does this score mean?")
- Announcing a small feature update via a badge + tooltip
- Providing form field guidance ("Password must be 8+ characters")
Design Patterns
- Hover/tap-triggered: Appears on interaction, not automatically
- Auto-appear once: Shows automatically the first time, never again
- Badge-triggered: A dot/number indicator that reveals a tooltip on tap
Placement Rules
- Position adjacent to the element it explains—never floating disconnected
- Ensure it doesn't block other critical UI on smaller screens
- Point/arrow clearly indicating what it refers to
Tooltips vs Other UI Patterns
See our related guides: coach marks for sequenced tours, nudges for broader behavioral prompts, and modals for high-priority interruptions.
Best Practices
- Keep copy under 15 words
- Show once, remember dismissal state per user
- Never use for critical actions the user must complete (use a modal instead)
- Test on smaller screens to ensure no overlap issues
Conclusion
Tooltips are the lightest-touch way to educate users contextually. Use them for secondary, non-critical explanations, keep copy minimal, and always remember dismissal state to avoid repeat annoyance.
