- Use italics only for emphasis, not as the default style for headings or large text blocks.
Avoid italicizing entire heading levels, since it reduces scannability and weakens visual hierarchy.
Keep italics short and infrequent, as long passages in italics are harder to read.
Ensure italics are not the sole indicator of meaning, especially for accessibility.
- Occasional, purposeful use of italics in headings is fine (such as for Trusted to Lead or other campaigns).
Line height
Line heights should create enough breathing room for the eye to track lines without losing place. Accessibility guidance favors slightly generous line spacing, especially for body text.
Recommendations
- 1.1–1.3 line height for headings
1.4-1.6 line height for body text
Tighter line heights reduce readability, especially on small screens or dense layouts.
Extra spacing improves comprehension for users with dyslexia or low vision.
Maintain consistent line height across similar text types to support predictable scanning.
Serif vs. San-serif
Sans‑serif fonts are preferred for digital interfaces because they remain clearer at small sizes and on varied screens. Serifs can still work well when used intentionally and with strong contrast and sizing.
- Avoid serif body text at small sizes, where details blur and slow reading.
- Serifs can be effective for large headings or brand‑driven typography.
