With over 43% of all websites built on WordPress, making the platform accessible has never mattered more. An inaccessible website is the equivalent of a locked door - and in 2026, rising awareness, stricter laws, and a commitment to digital inclusion have made accessibility non-negotiable. This guide covers why WordPress accessibility matters, the laws that apply (including AODA), the common challenges, the best plugins and themes, and the best practices to stay compliant.
TL;DR: Build to WCAG Level AA using an accessibility-ready theme (Astra, GeneratePress, OceanWP), fix the common barriers (contrast, alt text, keyboard, forms, captions), and use accessibility plugins to scan and remediate. If you operate in Ontario, AODA compliance is mandatory.
Digital accessibility means designing sites everyone can use, including people who are blind or have low vision, are deaf or hard of hearing, or have motor or cognitive disabilities. According to the World Health Organization, over 1.3 billion people globally live with some form of disability - nearly 16% of the population - and in Canada, 22% of people aged 15 and older identify as having a disability. Yet a 2023 WebAIM study found 96.3% of the top one million website homepages had detectable WCAG failures. Accessible WordPress sites aren't just more inclusive - they're better for SEO and lower your legal risk.
WordPress sites are governed by overlapping standards and laws, nearly all of which point to WCAG:

Tools alone aren't enough - pair them with these practices:
Run an accessibility plugin scan, then validate manually with a keyboard and screen reader, since automation can't catch everything. For a thorough review, follow our accessibility audit checklist and baseline with the WCAG checker. Finally, monitor continuously - new posts, plugins, and theme updates can reintroduce issues - and consider an accessibility widget to give users on-demand adjustments.
WordPress powers over 43% of all websites. Beyond inclusion for the 1.3 billion+ people with disabilities worldwide, accessibility reduces legal risk and improves SEO - and a 2023 WebAIM study found 96.3% of top homepages had WCAG failures.
WP Accessibility, Accessibility Checker, the UserWay widget, WP ADA Compliance Check Basic, and the Color Contrast Accessibility Validator.
If you operate in Ontario with one or more employees, AODA applies and requires WCAG 2.0 Level AA. Federally regulated Canadian organizations must also meet the Accessible Canada Act (WCAG 2.1 AA).
A theme built with proper semantics, keyboard support, and good contrast - for example Astra, GeneratePress, or OceanWP.
Start with an accessibility-ready theme, use proper headings, add alt text, ensure keyboard navigation and accessible forms, meet contrast requirements, use relative font sizes, then test with a plugin plus a manual keyboard and screen reader check.
WordPress makes accessibility achievable for everyone - if you build it in deliberately. Start with an accessibility-ready theme, meet WCAG Level AA, use the right plugins, follow the best practices above, and understand the laws that apply (AODA in Ontario, the ACA federally). Do that, and your WordPress site becomes inclusive, compliant, and better for both users and search engines.
