What is a design that can be accessed, understood, and used to the greatest extent possible by all people regardless of their age, size, ability or disability?

• A. Universal design
• B. Accessibility
• C. Inclusive design
• D. Adaptive design

Answer: (A)

Designing for universal use means creating products and environments that are usable by the widest range of people possible—across ages, body sizes, abilities, and contexts—with little or no need for adaptation. This approach aims to maximize accessibility and ease of use from the start, so everyone can interact with the design effectively.

That mindset aligns with universal design, which emphasizes broad usability for all people. Accessibility focuses on removing barriers for people with disabilities, which is essential but narrower in scope. Inclusive design is closely related, looking to include diverse users throughout the design process, but universal design specifically targets broad usability for everyone by default. Adaptive design involves changing features to suit individual needs, which can be powerful but isn’t about designing once for everyone from the outset.

So the best fit for a design intended to be usable by all people to the greatest extent possible is universal design.
