Which is the minimum clear width for most standard exterior exits?

• A. 28 inches
• B. 32 inches
• C. 34 inches
• D. 36 inches

Answer: (B)

The minimum clear width for most standard exterior exits is 32 inches. This is the unobstructed opening you have when the door is swung fully open to 90 degrees, taking into account the door frame and hardware. This width helps ensure safe and efficient egress for all occupants, including those using mobility aids. A narrower opening, like 28 inches, would not meet typical egress and accessibility requirements, while wider openings (34 or 36 inches) are not the minimum standard even though they may be required in certain situations.
