The walkthrough
Step by step.
Step 1 of 5
Hierarchy and Visual Weight
Guide users' attention using size, color, and contrast. Most important elements should stand out. Use headings hierarchy (H1 > H2 > H3). Primary actions should be visually prominent.
- Squint test - blur your eyes, important elements should still stand out
- Limit to 3 levels of hierarchy per screen
Step 2 of 5
Consistency and Patterns
Use consistent spacing, colors, typography, and components throughout your design. Users learn patterns quickly. Same actions should look and behave the same way everywhere.
- Create a design system early
- Document patterns for team consistency
Step 3 of 5
White Space and Breathing Room
Empty space is not wasted space. It improves readability and focus. Group related items, separate unrelated ones. Use margins and padding generously.
- When in doubt, add more white space
- Use consistent spacing units (8px grid system)
Step 4 of 5
Color and Contrast
Use color purposefully. Primary color for main actions, secondary for less important. Ensure sufficient contrast (4.5:1 for text). Use color to convey meaning but don't rely solely on it.
- Test with color blindness simulators
- Limit color palette to 3-5 colors
Step 5 of 5
Typography Best Practices
Choose 2 fonts maximum (one for headings, one for body). Line length: 50-75 characters. Line height: 1.5-1.75 for body text. Adequate font size: minimum 16px for body text.
- Use system fonts for faster loading
- Align text left for better readability
