For occupancies rated over 10, what is the maximum width of a single leaf door?

• A. 36 inches
• B. 32 inches
• C. 52 inches
• D. 48 inches

Answer: (D)

In means of egress design, the width of an exit door is tied to occupant load. For occupancies with an occupant load over 10, a single door leaf cannot exceed 48 inches in width. This limit helps ensure safe, unobstructed passage for people during an evacuation and keeps hardware, swing clearance, and structural considerations practical. If more total width is needed, you would use a pair of doors (double doors) or another configuration, rather than widening a single leaf beyond 48 inches.
