WCAG 2.1 on Sanity: complete compliance checklist
Implementing WCAG 2.1 compliance on Sanity means addressing the platform's specific failure modes (schema design without required alt text, portable text renderers losing semantics) while applying Web Content Accessibility Guidelines 2.1 success criteria across content, code, and editorial workflow.
WCAG 2.1 in 60 seconds
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.
Sanity accessibility — what you are starting with
Sanity's headless model means accessibility is delivered downstream. The Studio is reasonably accessible; the failure mode is schema design and front-end rendering.
WCAG 2.1 setup checklist for Sanity
1. Require alt text in image schema: Validation rules at schema level.
2. Audit Portable Text renderer: Map block types to semantic HTML.
Common WCAG 2.1 failures on Sanity
• Schema design without required alt text
• Portable Text renderers losing semantics
Putting it together
Combine WCAG 2.1's AA requirements with Sanity's native tooling. Bake accessibility into your component library and editorial workflow; instrument axe-core in CI for regression.
