Inclusive Design

Accessibility & Usability

Accessibility Score

Excellent Accessibility

Accessibility Features of Source Sans 3

Source Sans 3 scores in the excellent accessibility tier, making it well-suited for body text, UI labels, and long-form reading across devices. Grotesques with ambiguous letterforms (I/l/1) reduce accessibility. Choose designs with distinct character differentiation and open apertures for inclusive typography.

Source Sans 3's Legibility

Source Sans 3 draws legibility from its no serif extensions on stroke terminals and stroke contrast ranging from monolinear to subtly modulated. These characteristics help readers distinguish similar glyphs such as I, l, and 1 at a range of sizes.

Source Sans 3 in Context: Readability

Humanist sans-serifs offer the best body-text readability in the category. Geometric and neo-grotesque designs excel in short-form UI text but require careful sizing for sustained reading. Use at 16 px minimum for body text, and maintain 1.5 line-height to support comfortable reading rhythm.

Visual Comfort with Source Sans 3

Source Sans 3 provides a focused weight range that maintains consistent typographic color across paragraphs. Balanced stroke modulation keeps visual noise low during sustained reading sessions.

Source Sans 3 Accessibility Recommendations

Maintain a minimum contrast ratio of 4.5:1 for body text and 3:1 for large text when setting Source Sans 3. Use font sizes of at least 16 px for paragraph copy and line spacing of 1.5 or greater. Test Source Sans 3 at 200% browser zoom to confirm line breaks and layout integrity remain intact.

Best Practices for Using Source Sans 3

Pair with Garalde or Transitional serifs for classic contrast. A humanist sans body with a geometric sans display creates intra-category tension without conflict. A focused set of pairings helps designers find compatible companions for Source Sans 3. Establish hierarchy through size, spacing, and color rather than multiplying font families. Serve Source Sans 3 in WOFF2 format with its extended character set to ensure consistent rendering across global audiences.
