Web accessibility refers specifically to websites and web content. Digital accessibility is the broader term that covers websites plus mobile apps, software, PDFs, electronic documents, kiosks, and any other digital asset. Every web accessibility project is a digital accessibility project, but not every digital accessibility project is a web accessibility project. The standards and laws often overlap (WCAG applies to both), but the scope of what gets evaluated is where the two terms part ways.
| Term | What It Covers |
|---|---|
| Web Accessibility | Websites and web content evaluated against WCAG (typically 2.1 AA or 2.2 AA). |
| Digital Accessibility | Websites, web apps, mobile apps, software, PDFs, documents, kiosks, and other digital assets. |
| Shared Standard | WCAG 2.1 AA or 2.2 AA is the reference standard for most digital assets, including web. |
| Common Laws | ADA Title II and Title III, Section 508, EN 301 549, and the European Accessibility Act. |
What Is Web Accessibility?
Web accessibility is the practice of making websites and web content usable by people with disabilities. This includes people who rely on screen readers, keyboard navigation, speech input, magnification, and other assistive technology.
The reference standard is the Web Content Accessibility Guidelines (WCAG), most commonly at the 2.1 AA or 2.2 AA level. A web accessibility audit evaluates a site against those success criteria and identifies issues for remediation.
When someone says “web accessibility,” they are almost always talking about a website: marketing pages, ecommerce stores, informational sites, blogs, and the web-based portions of larger products.
What Is Digital Accessibility?
Digital accessibility is the umbrella term. It covers any digital asset a person might interact with, not only websites.
That includes websites and web apps, native mobile apps on iOS and Android, desktop software, SaaS products and internal tools, PDFs and electronic documents, learning management systems and EdTech content, kiosks, ATMs, and embedded systems, and email templates and electronic communications.
Digital accessibility applies the same core principles (perceivable, operable, understandable, and applicable across formats) across every format. WCAG is still the anchor for most of these assets, with EN 301 549 extending coverage to hardware and non-web software in European procurement contexts.
Why Does the Distinction Matter?
Scope. When a company asks for a “web accessibility audit,” they typically mean one website. When a company asks for a “digital accessibility program,” they usually mean an inventory of every digital asset across the organization, with a plan to evaluate and remediate each one.
The difference affects budget, timeline, and internal ownership. A single website audit is a defined project. A digital accessibility program is ongoing work that spans product teams, marketing, HR, procurement, and vendor management.
It also affects how laws apply. ADA Title II covers state and local government web content and mobile apps. Section 508 covers federal agency information and communication technology, which goes well beyond websites. The European Accessibility Act covers products and services including ebooks, banking, ecommerce, and transportation, across web and non-web formats.
Do the Same Standards Apply?
Mostly, yes. WCAG is the reference standard for web content, mobile apps, and most software interfaces. The same success criteria that govern a website also govern a mobile app, though the implementation details differ (touch targets, native gestures, platform accessibility APIs).
EN 301 549 incorporates WCAG and adds requirements for hardware, non-web software, and documentation. Section 508 aligns with WCAG 2.0 AA at the federal level. The European Accessibility Act references EN 301 549, which in turn references WCAG.
So the technical foundation is consistent. What changes is the range of products and services pulled into scope.
How Do You Decide Which Term to Use?
Use “web accessibility” when the conversation is specifically about a website. Use “digital accessibility” when the conversation covers multiple asset types or an organization-wide program.
If you are procuring a SaaS product, the vendor’s VPAT or ACR likely covers digital accessibility across the web app, any mobile app, and supporting documentation. If you are a government agency working toward ADA Title II conformance, you are running a digital accessibility program with web content as one piece of it.
FAQs
Is web accessibility part of digital accessibility?
Yes. Web accessibility is a subset of digital accessibility. Every website falls under the digital accessibility umbrella, but digital accessibility also includes mobile apps, software, PDFs, and other formats that are not websites.
Does WCAG cover both web and digital accessibility?
WCAG was written for web content, but it is applied to mobile apps, software, and electronic documents as the closest available standard. For non-web software and hardware, EN 301 549 extends WCAG with additional requirements.
Do I need separate audits for a website and a mobile app?
Yes. Each digital asset is evaluated separately because the platforms, assistive technology interactions, and implementation patterns differ. A website audit and a mobile app audit are two distinct engagements even when they cover the same product.
Which term should appear in our accessibility policy?
Use “digital accessibility” in policies that cover the organization’s full range of assets. Use “web accessibility” only if the policy is scoped to websites alone. Most organizations benefit from the broader term because it anticipates future assets without requiring a policy rewrite.
Are the laws the same for web and digital accessibility?
The same laws often apply to both, but the scope of covered assets differs. ADA Title II covers web content and mobile apps for state and local governments. The EAA covers a wide set of products and services across web and non-web formats. Section 508 covers federal ICT broadly.
The terms are related, but they are not interchangeable. Pick the one that matches the scope of what you are actually covering, and the rest of the conversation (audits, standards, budget) gets clearer from there.
