Which universal design principle states the design is usable by people with diverse abilities and doesn't require adaptation?

• A. Equitable Use
• B. Size and Space for Approach and Use
• C. Simple and Intuitive
• D. Perceptible Information

Answer: (A)

Equitable use means a design is usable by people with diverse abilities without needing to adapt or special-case it. It aims for equal access and function for all users, so no one is forced into a separate version or workaround. For example, features like curb cuts, doors with accessible handles, or websites with consistent navigation work well for wheelchair users, people with limited vision, and others without requiring adjustments. The other principles focus on different aspects: ensuring there’s enough physical space for everyone to approach and use the product, making the design easy to learn and use, and presenting information in ways that can be perceived by different senses. Equitable use is specifically about broad, barrier-free usability for all, without adaptation.
