What is ADA Compliant? Meaning, Requirements & Guide 2026

If you've ever asked "what is ADA compliant?" — you're not alone. The term ADA compliant means that a website, product, or service meets the accessibility standards required by the Americans with Disabilities Act (ADA). In the context of websites, being ADA compliant means your site is accessible to people with disabilities, including those who are blind, have low vision, are deaf, have motor impairments, or experience cognitive disabilities.

This comprehensive guide explains everything you need to know about ADA compliance — from its meaning and requirements to how to make your website ADA compliant in 2026.

ADA vs WCAG — What's the Difference?

Many people confuse ADA and WCAG. Here's the difference:

• ADA is a law that prohibits discrimination against people with disabilities. It applies to all areas of public life, including websites.
• WCAG is a technical standard that defines how to make websites accessible. It provides specific guidelines and success criteria.

Put simply: ADA is the law, WCAG is the standard. To comply with the ADA, your website must follow WCAG 2.1 Level AA guidelines.
