Accessibility & Usability

86
Accessibility Score
Excellent Accessibility

Using Boisu Accessibly

Boisu scores in the excellent accessibility tier, making it well-suited for body text, UI labels, and long-form reading across devices. Decorative features may reduce legibility for users with cognitive disabilities. Always provide sufficient size contrast between display and body text.

Boisu Legibility Characteristics

Boisu draws legibility from its tight spacing optimized for large point sizes and exaggerated contrast, weight, or decorative features. These characteristics help readers distinguish similar glyphs such as I, l, and 1 at a range of sizes.

How Readable is Boisu?

Designed exclusively for sizes above 24 pt. Display faces sacrifice small-size legibility for visual impact and personality at headline scale. Use at 16 px minimum for body text, and maintain 1.5 line-height to support comfortable reading rhythm.

Boisu: Comfort in Extended Reading

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

Boisu Accessibility Recommendations

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

Working with Boisu: Best Practices

Anchor with a neutral text serif or sans-serif. The display face should carry personality while the text face carries readability. Curated pairings are available to guide complementary typeface selection for Boisu. Establish hierarchy through size, spacing, and color rather than multiplying font families. Serve Boisu in WOFF2 format for optimal load performance and broad browser compatibility.
