WCAG 2.2 Becomes an ISO Standard: What It Means for Your Website

The Web Content Accessibility Guidelines (WCAG) have officially reached a new milestone. The World Wide Web Consortium (W3C) has announced that WCAG 2.2 is now recognised as an international standard - ISO/IEC 40500:2025.

It’s a quiet but significant step that will reshape how organisations approach digital accessibility worldwide.

Why ISO Approval Matters

WCAG has long been the global benchmark for digital accessibility. Its guidelines help organisations make websites and apps usable by people with auditory, cognitive, neurological, physical, speech, and visual impairments.

It also benefits older users and anyone whose abilities change over time.

Now that WCAG 2.2 is an ISO standard, it gains formal international recognition. Governments and regulators can adopt it more confidently as a compliance requirement, and businesses can use it as a clear, trusted reference point.

For companies operating in the EU, it closely aligns with the European Accessibility Act (EAA) and other legislation, helping to future-proof digital services before new rules come into force.

From Guidelines to Global Standard

Until now, WCAG was widely respected but technically advisory. ISO approval elevates it from recommendation to recognised benchmark.

This matters because many industries already rely on ISO standards for quality, security, and sustainability. Adding accessibility to that list means it will now be taken more seriously in procurement, audits, and legal frameworks.

If your organisation manages any digital product — a website, app, or internal system — accessibility can no longer be left for later. The standard has shifted.
