If you're looking into how to make your website accessible—and legally compliant—you've likely come across two important acronyms: ADA and WCAG.
The Americans with Disabilities Act (ADA) is the U.S. law that prohibits discrimination against people with disabilities, including in digital spaces. Meanwhile, WCAG, or the Web Content Accessibility Guidelines, are the global gold standard for web accessibility.
Understanding how these two relate—and what each means for your business—is essential; whether you’re aiming to reduce legal risk, improve your user experience, or both.
In this guide, we’ll break down the relationship between the ADA and WCAG, explain how compliance works, and show how tools like accessiBe can support your accessibility goals.
1. The ADA is a law. WCAG are standards.
The Americans with Disabilities Act (ADA) is a law enacted to protect the rights of people with disabilities. Title III of the ADA, relevant to businesses’ categorized as “public accommodations” (which is most public-facing businesses), is now widely applied to websites, as well. What this means is that relevant businesses must ensure their websites are accessible to people with disabilities, under the ADA.
WCAG, on the other hand, exists independently from the ADA. Developed by the World Wide Web Consortium (W3C), the Web Content Accessibility Guidelines (commonly referred to as WCAG) are leaned upon by organizations looking to create inclusive digital environments, regardless of whether they are legally obligated to do so.
There are three versions of WCAG: WCAG 2.0, WCAG 2.1, and WCAG 2.2.
Each version of WCAG offers three levels of conformance website owners can adhere to:
- Level A: The most basic level of accessibility
- Level AA: A higher level of accessibility
- Level AAA: The highest level of accessibility and most difficult to achieve

2. U.S. courts point to WCAG when interpreting the ADA

Although WCAG isn’t formally written into law, U.S. courts consistently refer to it when ruling on website accessibility cases under the ADA.
In most rulings, courts point to WCAG 2.0, 2.1, or 2.2, at Level AA conformance, as the benchmark for determining whether a website is accessible.
In short: If you're aiming to comply with the ADA, WCAG 2.1 Level AA is the standard to adhere to.
While the Department of Justice (DOJ) has not officially codified WCAG as the legal standard, it has repeatedly referenced it—including as recently as April 2024—when offering guidance and enforcing ADA compliance in digital contexts.

In a recent case involving an accessiBe customer, United States District Court for the Eastern District of New York recognized accessWidget as a measure that promotes accessibility.
Leveraging accessiBe’s Litigation Support, the defendant successfully proved how accessWidget helped him adhere to key WCAG guidelines under the ADA.
Dismissing the case, the judge ruled that the defendant’s ‘use of an accessibility widget”, was "sufficient to assure the Court that there is no reasonable expectation that the issues purportedly identified by Plaintiff will recur."
