Frequently asked questions about event capacity

Event capacity is calculated by dividing the usable venue area (in square feet or meters) by the space needed per person based on the event layout. Standing events typically need 5–7 sq ft per person, theater seating needs 7–9 sq ft, and banquet seating needs 12–16 sq ft. Always subtract space for stages, bars, exits, and equipment before calculating.
