Typography is the silent ambassador of your brand. Every font choice communicates something about your product before a single word is read. Mastering typography means balancing aesthetics with readability, personality with practicality.
Choosing Your Font Stack
A font stack is a prioritized list of fonts for the browser to use. A well-structured stack looks like this:
The strategy is simple: pick one display font that reflects your brand, then fall back to system fonts for performance and reliability. System fonts load instantly because they're already installed on the user's device.
When selecting fonts, consider:
Readability at small sizes — Body text must be legible at 14px and below
Character variety — Ensure your chosen font has bold, italic, and medium variants
License compatibility — Verify the font can be used commercially and embedded in web projects
Establishing a Type Scale
A type scale creates visual hierarchy and rhythm. Here's a practical scale for most interfaces:
Level
Size
Weight
Use Case
Heading 1
36px
Bold
Page titles
Heading 2
28px
Semi-bold
Section headers
Heading 3
22px
Semi-bold
Card titles
Body large
18px
Regular
Lead paragraphs
Body
16px
Regular
Default body text
Body small
14px
Regular
Captions, metadata
Caption
12px
Regular
Legal text, hints
Keep your type scale consistent across all pages. Users should instantly recognize your product by its typographic rhythm.
Line Length and Spacing
The single most common typography mistake is setting line length too wide. For optimal readability:
Body text — 50–75 characters per line (roughly 60–65 is ideal)
Headings — Can be wider, but keep them centered or left-aligned consistently
Line height — 1.4–1.6 for body text, 1.2–1.3 for headings
Letter spacing — Slightly increase for all-caps headings (+0.5px to +1px)
Never justify text in UI design — the uneven word spacing creates rivers of white space that hurt readability. Left-align or center instead.
Accessibility Considerations
Typography accessibility goes beyond contrast:
Use at least 16px for body text
Ensure sufficient color contrast between text and background
Avoid relying solely on font weight to distinguish elements
Test with screen readers to ensure proper heading hierarchy (h1 through h6)
Never use font size alone to convey meaning — pair with icons or labels
Conclusion
Good typography is invisible — users don't notice it when it's done right. They notice when it's wrong. Start with a strong font stack, establish a clear type scale, and never compromise on readability. Your users will read more, understand better, and trust your product more.

The Signal
AI-generated brief
Rigorous typographic discipline—anchored by strategic font stacking, constrained spatial metrics, and mandatory accessibility checks—is essential for building fast, readable, and trustworthy interfaces.

Key takeaways
Deploy a tiered font stack that pairs a single branded display face with OS-native fallbacks to guarantee instant rendering and cross-platform stability.
Maintain a strict type scale and limit body lines to 50–75 characters with 1.4–1.6 line height to sustain visual rhythm and reduce reading friction.
Enforce inclusive design by capping body text at a 16px minimum, eliminating justified alignment, and verifying semantic heading structures with assistive tools.
