What Is Accessibility?

What is accessibility

To answer what is accessibility, it’s the practice of ensuring that products, services, environments, and digital experiences are usable by as many people as possible, regardless of their abilities or disabilities. Often abbreviated as a11y (where the “11” represents the 11 letters between the “a” and “y”), accessibility is a fundamental aspect of inclusive design, aiming to remove barriers that prevent individuals from fully participating in society. Whether in physical spaces, digital platforms, or everyday products, what is accessibility about? It ensures that everyone—regardless of physical, sensory, or cognitive limitations—can engage meaningfully with the world around them.

In this blog, we’ll delve into the concept of accessibility, its importance, principles, types, real-world applications, and the impact it has on both individuals and society. By the end, you’ll have a clear understanding of accessibility and how to incorporate it into various contexts, from web design to public spaces.

What Is Accessibility?

At its core, what is accessibility? It refers to designing systems, environments, products, or services so that they are usable by people with a wide range of abilities and disabilities. This includes individuals with visual, auditory, motor, cognitive, or neurological impairments, as well as those with temporary or situational limitations (e.g., a broken arm or a noisy environment).

Accessibility is not just about compliance with laws or standards; it’s about empathy and inclusion. It recognizes that people experience the world differently and seeks to create equitable opportunities for everyone to participate. Accessibility is often associated with disability, but its benefits extend to all users, including older adults, non-native language speakers, and those using assistive technologies.

Key Areas of Accessibility

Understanding what is accessibility involves recognizing its various domains, including:

  • Digital Accessibility: Ensuring websites, apps, and digital content are usable by people with disabilities, such as through screen readers or keyboard navigation.
  • Physical Accessibility: Designing buildings, public spaces, and transportation systems to accommodate mobility aids like wheelchairs or walkers.
  • Communication Accessibility: Providing sign language interpretation, captions, or braille for individuals with hearing or visual impairments.
  • Cognitive Accessibility: Simplifying language, interfaces, or instructions to support individuals with cognitive or learning disabilities.

What is accessibility, and why does it matter? Accessibility is both a moral and practical necessity. Here’s why it matters:

Promotes Inclusion and Equity

Approximately 15% of the global population—over 1 billion people—live with some form of disability, according to the World Health Organization (WHO). By prioritizing accessibility, we ensure that these individuals can access education, employment, healthcare, and entertainment on equal terms. Accessibility fosters a sense of belonging and reduces discrimination.

Legal and Ethical Responsibility

Many countries have laws mandating accessibility, such as the Americans with Disabilities Act (ADA) in the United States, the Accessibility for Ontarians with Disabilities Act (AODA) in Canada, and the Web Content Accessibility Guidelines (WCAG) globally. Failing to comply can result in legal repercussions, but beyond that, accessibility reflects an ethical commitment to fairness and human rights. See our WCAG compliance guide.

Benefits for Everyone

Accessible design often improves the user experience for all. For example:

  • Curb cuts (ramps at sidewalks) benefit wheelchair users, parents with strollers, and delivery workers.
  • Closed captions help deaf individuals but also assist people in noisy environments or non-native speakers.
  • Clear navigation on websites aids users with cognitive disabilities and enhances usability for everyone.

Business Advantages

Businesses that prioritize accessibility tap into a larger market, improve customer satisfaction, and enhance their brand reputation. Inaccessible websites or products can alienate potential customers, while accessible ones build loyalty and trust. Additionally, accessibility can boost search engine optimization (SEO), as search engines favor well-structured, accessible websites.

Principles of Accessibility

What is accessibility: Why web accessibility matters

The Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium (W3C), provide a global standard for digital accessibility. These guidelines are organized around four core principles, often summarized as POUR, which help clarify what is accessibility in digital contexts:

  1. Perceivable: Information and user interface components must be presented in ways that users can perceive, regardless of their sensory abilities.
    • Examples: Providing text alternatives for images (alt text), captions for videos, and high-contrast visuals.
  2. Operable: User interface components and navigation must be operable by all users, regardless of how they interact with the system.
    • Examples: Ensuring websites are navigable via keyboard, providing sufficient time for users to complete tasks, and avoiding flashing content that could trigger seizures.
  3. Understandable: Information and operation of the user interface must be clear and easy to understand.
    • Examples: Using plain language, consistent navigation, and predictable functionality.
  4. Robust: Content must be compatible with a wide range of assistive technologies and devices, both now and in the future.
    • Examples: Using semantic HTML, ensuring compatibility with screen readers, and testing across browsers.

These principles apply not only to digital accessibility but also to broader contexts like architecture, product design, and communication.
