Typography is more than just choosing a font. It plays a fundamental role in how users interact with and understand your interface. In the world of UI/UX design, well-executed typography improves readability, creates visual hierarchy, and enhances the overall user experience.
This blog provides essential typography tips that will help designers craft clear, accessible, and engaging user interfaces.
Why Typography Matters in UI Design
Typography affects how users perceive information, navigate layouts, and engage with content. Poor typography can lead to:
-
Confusion and frustration
-
Difficulty in reading or scanning content
-
Reduced trust in the product
On the other hand, great typography:
-
Directs attention effectively
-
Communicates brand personality
-
Improves usability and accessibility

1. Choose Readable Fonts
Always prioritize legibility over style. Choose fonts that are easy to read across different screen sizes and resolutions. Sans-serif fonts like Roboto, Open Sans, or Lato are commonly used in digital interfaces due to their clarity.
Avoid overly decorative fonts in body text. Reserve stylized fonts for headers or branding.

2. Establish a Visual Hierarchy
Typography helps establish a visual hierarchy by organizing content into sections of importance. Use variations in:
-
Font size
-
Weight (regular, bold)
-
Color
-
Letter spacing
A clear hierarchy makes it easier for users to scan and understand content quickly.

3. Stick to a Limited Font Palette
Using too many fonts can make your design look chaotic. Most designers follow the “two-font rule”—one for headings and another for body content.
Consistent font usage promotes visual cohesion and a better user experience.

4. Use Appropriate Font Sizes
Font size should adapt to different screen sizes and contexts. For example:
-
Headlines: 24–32px
-
Subheadings: 18–24px
-
Body text: 14–16px
Always test your typography on both mobile and desktop screens for responsive readability.

5. Maintain Proper Line Spacing and Letter Spacing
Poor spacing can ruin even the best typefaces. Maintain enough line height (usually 1.4–1.6x the font size) and letter spacing to enhance legibility.
Proper spacing creates breathing room and prevents visual clutter.

6. Choose the Right Line Length
The optimal line length for body text is 50–75 characters per line. Anything longer or shorter may cause strain or confusion for the reader.
Breaking content into shorter lines also improves content scannability, especially on smaller screens.

7. Consider Accessibility
Typography should support inclusive design. Use sufficient contrast between text and background to meet WCAG accessibility standards. Avoid low-contrast text (e.g., light gray on white).
Also, ensure your text is readable by screen readers by avoiding text embedded in images.

8. Use Web-Safe Fonts or Host Custom Fonts Properly
If you’re using custom fonts, make sure they load quickly and display correctly. Alternatively, choose web-safe fonts or host Google Fonts for optimal performance.
Font loading issues can disrupt the user experience and cause layout shifts.

9. Test Across Devices and Resolutions
Typography must be responsive. What looks good on a large desktop may be unreadable on a smartphone. Use media queries and fluid typography techniques to adjust sizes and spacing based on screen size.

10. Align Text for Better Flow
Left-aligned text is typically the most readable for Western languages. Centered or right-aligned text should be used sparingly, mainly for headings or callouts.
Proper alignment improves text flow and reduces cognitive load.
