Accessibility (A11y)

Definition

Accessibility (often abbreviated as A11y) is the design practice of making digital products and services usable for all people, including those with disabilities. This involves ensuring that interfaces are compatible with assistive technologies like screen readers and providing features like keyboard navigation, high contrast modes, and alternative text for images. A focus on accessibility makes digital experiences inclusive, promoting equal access to information and services for all users.

Why it matters

Accessibility isn't just a legal checkbox — it directly expands your addressable market and improves experience for everyone. Features like keyboard navigation, clear contrast, and descriptive labels help users with disabilities, but also benefit people on slow connections, mobile devices, or in bright sunlight. For B2B SaaS products especially, enterprise procurement teams increasingly require WCAG compliance before signing contracts.

Real-world example

Stripe's payment forms are fully keyboard-navigable and screen-reader compatible, which is a key reason enterprise teams trust them — it signals quality and thoroughness throughout the entire product.
