Which universal design principle is Size and Space for Approach and Use?

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

Answer: (D)

Size and Space for Approach and Use focuses on ensuring there is enough clearance and maneuvering room for people to approach, reach, and operate a space or device, regardless of body size, posture, or mobility aids. This means considering door widths, clear floor space, knee and toe clearance, and turning space so a person can comfortably and safely access controls, furniture, or equipment. The other principles address different accessibility aspects—Equitable Use aims for the same experience for all users, Simple and Intuitive emphasizes ease of understanding, and Perceptible Information ensures information is perceivable by everyone—without specifically ensuring the physical space needed to approach and use.
