Typography for All: Font Choice and Readability
Introduction
Typography plays a pivotal role in both the visual design and user experience of a website. It's more than just choosing a "pretty font"—typography directly influences how easily users can consume information, navigate content, and engage with the digital environment. For people with vision impairments, dyslexia, cognitive disabilities, or reading difficulties, typography can be the bridge between access and exclusion.
In the realm of web accessibility, font choice and readability are core considerations. Websites today must meet the diverse needs of users, including those defined under accessibility guidelines such as WCAG (Web Content Accessibility Guidelines), Section 508 (U.S.), ADA (Americans with Disabilities Act), EN 301 549 (EU), and the European Accessibility Act (EAA). As a result, making typographic decisions based on accessibility best practices is not just ethical—it’s strategic.
In this article, we’ll dive deep into how font selection impacts user experience and accessibility, the key principles for creating readable typography, and how tools like allyWay help businesses make smarter, more inclusive decisions in web design.
Why Typography Matters in Web Accessibility
Typography is a fundamental building block of digital content. Whether it's an e-commerce site, blog, government portal, or mobile application, well-designed typography ensures that all users—regardless of their abilities—can understand, interpret, and interact with text content.
Key Accessibility Issues Related to Typography
- Visual clarity: Fonts that are too ornate or tightly spaced can hinder readability.
- Scalability: Poorly designed typography may not scale well when users zoom in or increase font size.
- Cognitive load: Complex fonts increase mental effort for users with dyslexia or cognitive impairments.
- Contrast: Inadequate contrast between text and background may render text unreadable for users with low vision or color blindness.
Typography choices aren’t just design preferences—they’re usability decisions that significantly affect accessibility and inclusivity.
Accessibility Guidelines Related to Typography
To develop respectful and inclusive typography, it's essential to understand the major accessibility standards that guide web content.
| Guideline | Description | Typography Considerations |
|---|---|---|
| WCAG | Web Content Accessibility Guidelines | Requires readable, scalable text with sufficient contrast and resizable fonts without loss of content. |
| ADA | Americans with Disabilities Act | Enforces digital accessibility in public-facing websites and applications in the U.S. |
| Section 508 | Amendment to the Rehabilitation Act (U.S.) | Requires federal websites to be accessible to all users. |
| EN 301 549 | European Union accessibility standard | Mandates accessibility in public sector websites and mobile apps in the EU. |
| EAA | European Accessibility Act | Applies to commercial websites and apps to ensure equal digital access. |
Important Reminder
Following these guidelines is a best practice, but no tool alone can "guarantee" legal compliance. Accessibility is a continuous improvement process. allyWay helps support and streamline that process for you.
Principles of Accessible Typography
Whether you're refreshing your website or launching a new digital product, consider these best practices to enhance readability and support accessibility.
1. Choose Readable Typefaces
Fonts can look stylish but still be difficult to read. Follow these general rules:
✓ Sans-serif fonts (e.g., Arial, Helvetica, Verdana) are typically more readable on screens.
✓ Avoid decorative or cursive fonts for body text.
✓ Use fonts designed for readability, such as Tahoma, Open Sans, or Lexend.
✓ Consider dyslexia-friendly fonts like Atkinson Hyperlegible or Dyslexie.
✓ Limit font choices to 2–3 per site to maintain consistency and reduce visual clutter.
2. Use a Comfortable Font Size
WCAG suggests that text should be resizable up to 200% without loss of content or functionality.
Recommended starting sizes:
- Body text: 16px
- Headings: Scale appropriately (1.5x–2x body size)
- Captions/Footnotes: Minimum 12px
3. Ensure Good Color Contrast
Color contrast between text and background affects readability for users with low vision or colorblindness. WCAG recommends:
- Normal text contrast: Minimum ratio of 4.5:1
- Large text (18pt+): Minimum ratio of 3:1
Use tools like contrast checkers or allyWay’s AI-powered audits to verify contrast compliance.
4. Maintain Sufficient Line Height and Spacing
Text should not feel cramped or disorganized. Ideal spacing enhances flow and legibility.
- Line height: 1.5x font size
- Letter spacing: At least 0.12x font size
- Word spacing: At least 0.16x font size
- Paragraph spacing: Consistent and generous (use vertical space)
5. Use Logical Hierarchy
Visual hierarchy organizes information so readers can easily scan and understand content.
- Use H1 to H6 heading structure (only one H1 per page)
- Follow semantic order and avoid skipping heading levels
- Bolder/larger fonts for headings, but don’t rely on style alone—use HTML structure for assistive technologies
6. Avoid Using Text in Images
Screen readers and other assistive technologies cannot interpret text embedded in images. If unavoidable:
✓ Provide alt text
✓ Ensure high contrast
✓ Avoid key information being conveyed solely through text images
