Typography
Ensuring legibility
Use font sizes that most people can read easily.
Test legibility in different contexts.
In general, avoid light font weights.
Conveying hierarchy
Adjust font weight, size, and color as needed to emphasize important information and help people visualize hierarchy.
Minimize the number of typefaces you use, even in a highly customized interface.
Prioritize important content when responding to text-size changes.
Using system fonts
Consider using the built-in text styles.
Modify the built-in text styles if necessary.
If necessary, adjust tracking in interface mockups.
Using custom fonts
Make sure custom fonts are legible.
Implement accessibility features for custom fonts.
Supporting Dynamic Type
Make sure your app’s layout adapts to all font sizes.
Increase the size of meaningful interface icons as font size increases.
Keep text truncation to a minimum as font size increases.
Consider adjusting your layout at large font sizes.
Maintain a consistent information hierarchy regardless of the current font size.
Platform considerations
macOS
When necessary, use dynamic system font variants to match the text in standard controls.
visionOS
In general, prefer 2D text.
Make sure text looks good and remains legible when people scale it.
Maximize the contrast between text and the background of its container.
If you need to display text that’s not on a background, consider making it bold to improve legibility.
Keep text facing people as much as possible.
