Bleacher and grandstand seating must provide how many inches per person?

• A. 12
• B. 20
• C. 22
• D. 18

Answer: (D)

Bleacher and grandstand seating is bench-style, so the code sets a minimum seating width per person to ensure everyone has enough space and that safe egress is possible. The required minimum is 18 inches of seating width for each occupant. This amount balances comfort, accessibility, and the ability for people to move past others and evacuate if needed.

Choices that give less than 18 inches would crowd seated occupants and hinder safe movement, while wider widths exceed the minimum but aren’t the standard requirement. Therefore, 18 inches per person is the correct standard.
