Typeface or Lawsuit? What Developers Need to Know About Font Compliance Before It's Too Late

You probably spent a solid afternoon picking the perfect typeface for your website. Maybe you went with something sleek and modern. Maybe you leaned into a quirky display font that felt so on-brand. But here's the thing nobody told you at design school: that font choice could land you in front of a judge.

Web accessibility lawsuits in the United States have been rising steadily, and while most people associate ADA compliance with ramps, elevators, and parking spaces, the digital world has its own version of those requirements — and typography sits squarely in the crosshairs.

The Lawsuit Landscape Is Getting Crowded

Let's set the scene. In 2023 alone, over 4,600 ADA-related digital accessibility lawsuits were filed in federal court, according to data from UsableNet. That number has been climbing since the early 2020s, and 2025 is shaping up to be another record-breaker. Retailers, healthcare providers, restaurants, and SaaS companies have all been named as defendants.

Many of these cases cite the Web Content Accessibility Guidelines (WCAG) — a set of technical standards developed by the W3C that have effectively become the legal benchmark for digital accessibility in the US. Courts have increasingly pointed to WCAG 2.1 (and now 2.2) when determining whether a website meets the ADA's "effective communication" standard.

So where does your font come in? More places than you'd think.

The Typography Traps That Fail WCAG Tests

WCAG doesn't name specific typefaces as illegal — it's not that simple. Instead, it sets out criteria that your text must meet, and certain font choices make it nearly impossible to hit those benchmarks.

Contrast ratios are the big one. WCAG 2.1 Level AA requires a minimum contrast ratio of 4.5:1 for normal-sized text and 3:1 for large text. Lightweight or ultra-thin fonts — think those wispy 100-weight sans-serifs that look gorgeous on a designer's Retina display — often tank contrast ratios even when your color palette technically passes. The letterforms themselves are too thin to register clearly against most backgrounds.

Decorative and script fonts are another minefield. Fonts that mimic cursive handwriting or have heavily stylized letterforms fail readability tests for users with dyslexia, cognitive disabilities, and low vision. The Americans with Disabilities Act has been interpreted to cover cognitive accessibility, not just physical impairment, which means that "charming" script font on your homepage could be a problem.

Justified text combined with the wrong typeface is a subtler trap. Fonts with inconsistent letter spacing or narrow character widths create uneven word gaps when justified, producing what accessibility experts call "rivers" of white space — a known barrier for users with dyslexia.

All-caps text in certain typefaces also raises red flags. While all-caps can be fine for short labels or buttons when used with accessible fonts, extended uppercase text in condensed or display typefaces dramatically reduces reading speed for users with cognitive processing differences.

Real Cases, Real Consequences

In Robles v. Domino's Pizza (a case that's been cited in accessibility circles for years), the Ninth Circuit ruled that the ADA applies to websites and apps tied to physical locations. While that specific case centered on screen reader compatibility, the legal precedent it set opened the door wide for typography-related claims.

More recently, plaintiffs' attorneys have gotten specific about visual presentation failures. Cases have cited font size minimums (WCAG recommends body text no smaller than 16px for most contexts), insufficient line spacing, and the use of low-contrast color-and-font combinations as evidence of non-compliance. Settlements have ranged from tens of thousands to several hundred thousand dollars, plus the cost of remediation.

Small businesses aren't immune, either. Serial filers — attorneys who file dozens or hundreds of similar suits — have specifically targeted smaller e-commerce sites and local service businesses that lack in-house legal teams to push back.

Fonts That Actually Hold Up

Here's the practical upside: accessible fonts are not boring fonts. Some of the most effective typefaces for compliance are also genuinely beautiful and versatile.

Georgia and Merriweather hold up exceptionally well for body copy — their generous x-heights and clear letterform differentiation make them readable across screen sizes and resolutions. Roboto, Open Sans, and Lato are workhorses of accessible web typography for good reason; they were designed with screen legibility as a primary goal. Atkinson Hyperlegible, developed by the Braille Institute, is one of the most defensible choices you can make — it was literally engineered for low-vision readers.

For display and heading use, Inter and Source Sans Pro offer flexibility without sacrificing clarity. If you want something with more personality, Nunito and DM Sans balance character with legibility better than most.

Your Practical Compliance Checklist

Before you ship your next project, run through these:

• Contrast ratio check: Use the WebAIM Contrast Checker on every text/background combination, at every font weight you're using
• Minimum size audit: Body text at 16px or larger; avoid anything below 14px anywhere on the page
• Weight review: Avoid font weights below 400 (Regular) for any body copy or important UI text
• Avoid purely decorative fonts for functional text: Navigation, CTAs, form labels, and legal text should never use script, display, or novelty typefaces
• Line height: Set to at least 1.5x your font size for body copy
• Letter spacing: Don't compress tracking on any text that users need to read to take action
• Test with real users: Run your site through a screen reader and, if possible, test with users who have low vision or dyslexia
• Document your choices: Keep a record of your WCAG compliance rationale — it's useful if you ever need to demonstrate good-faith effort

The Bottom Line

Accessibility compliance isn't about stripping the design out of your website. It's about making intentional choices that serve every user — and protect your business in the process. The good news is that tools like FontChanger make it easier than ever to test, swap, and refine your typography in real time, so you can find the intersection of beautiful and bulletproof before your site ever goes live.

Your font should be working for you, not against you. Make sure you know which side it's on.
