WCAG 2.1 vs WAD
WCAG 2.1 (Web Content Accessibility Guidelines 2.1, Global, 2018) and WAD (EU Web Accessibility Directive, European Union — public-sector bodies, 2016) are two of the most-referenced accessibility frameworks in digital compliance. This guide compares them side by side — jurisdiction, scope, conformance approach, penalties, and how a single audit can cover both simultaneously.
What is WCAG 2.1?
WCAG 2.1 is the World Wide Web Consortium's accessibility standard published June 2018, adding 17 success criteria to WCAG 2.0 — primarily addressing mobile, low vision, and cognitive disabilities — and currently referenced as the conformance baseline by the European Accessibility Act and most procurement frameworks.

World Wide Web Consortium (W3C)
Jurisdiction and enforcement
Global. Referenced by EN 301 549 (current EU baseline) and many national laws.
What is WAD?
The EU Web Accessibility Directive (Directive (EU) 2016/2102) requires public-sector bodies in all EU member states to make their websites and mobile apps accessible per EN 301 549, with mandatory accessibility statements and a complaints mechanism — operative since September 2018 for new sites and September 2020 for all sites.

Jurisdiction and enforcement
European Union — public-sector bodies. Per member state.
WCAG 2.1 vs WAD — the key differences
The principal difference is jurisdictional: WCAG 2.1 applies in Global, while WAD applies in European Union — public-sector bodies. WCAG 2.1 is maintained by World Wide Web Consortium (W3C); WAD is maintained by European Commission. The standards differ on scope, conformance grading, and penalty structure — but a well-designed accessibility programme can satisfy both simultaneously by adopting the strictest applicable requirement and cross-mapping findings.
Scope
WCAG 2.1 covers: Web content, Mobile web, Web applications. WAD covers: Public-sector websites and intranets, Public-sector mobile apps, Documents published by public bodies.
Penalties
WCAG 2.1: Same as WCAG 2.2 — penalties are downstream of the national law citing WCAG. WAD: Per-member-state.
How to comply with both at once
Adopt the stricter applicable conformance level — typically WCAG 2.2 Level AA — as your engineering baseline. Audit against that baseline once, then cross-map findings to both WCAG 2.1 and WAD specific requirements. A single Accessibility Conformance Report (ACR) using VPAT 2.5 INT can document both.
When you might need just one
If you operate exclusively in Global and have no cross-border procurement exposure, you may only need WCAG 2.1. The same applies in reverse for WAD. For organisations selling cross-border, into the EU or US public sector, the safer default is to plan to both simultaneously.

FAQ
Frequently asked questions
Cited answers. Sourced. Updated as standards and case law change.
Is WCAG 2.1 stricter than WAD?
Neither standard is uniformly "stricter" — they cover different regulatory domains. WCAG 2.1 is more prescriptive about web content; WAD about public-sector websites and intranets. For organisations exposed to both, a unified WCAG 2.2 AA baseline typically satisfies the technical requirements of both.
Can a single audit satisfy WCAG 2.1 and WAD?
Yes. Both standards ultimately reference WCAG-aligned criteria. A combined audit with cross-mapped findings can produce documentation acceptable to both regulators.
Which jurisdictions enforce WCAG 2.1?
Global. Referenced by EN 301 549 (current EU baseline) and many national laws.
Which jurisdictions enforce WAD?
European Union — public-sector bodies. Per member state.
What happens if I am not compliant with WCAG 2.1?
Same as WCAG 2.2 — penalties are downstream of the national law citing WCAG
What happens if I am not compliant with WAD?
Per-member-state
