Exit routes must be at least how many inches wide at all points?

• A. 24 inches
• B. 26 inches
• C. 28 inches
• D. 32 inches

Answer: (C)

Exit routes must be wide enough to allow people to evacuate smoothly and without bottlenecks. The minimum clear width required along the entire route is 28 inches. This ensures that an adult can pass through corridors, turns, and doors without crowding or having to back up, even if carrying belongings or assisting others. The width must be maintained at all points and kept free of obstructions, so any narrowing would compromise safe egress. So, 28 inches is the mandated minimum. Wider routes (like 32 inches) do meet the requirement, but the key point is the minimum threshold that must be present at every point along the exit route.
