Seating capacity

Seating capacity is the number of people who can be seated in a specific space, in terms of both the physical space available, and limitations set by law. Seating capacity can be used in the description of anything ranging from an automobile that seats two to a stadium that seats hundreds of thousands of people. The largest sporting venue in the world, the Indianapolis Motor Speedway, has a permanent seating capacity for more than 235,000 people and infield seating that raises capacity to an approximate 400,000. Safety is a primary concern in determining the seating capacity of a venue: "Seating capacity, seating layouts and densities are largely dictated by legal requirements for the safe evacuation of the occupants in the event of fire". The International Building Code specifies, "In places of assembly, the seats shall be securely fastened to the floor" but provides exceptions if the total number of seats is fewer than 100, if there is a substantial amount of space available between seats or if the seats are at tables. It also delineates the number of available exits for interior balconies and galleries based on the seating capacity, and sets forth the number of required wheelchair spaces in a table derived from the seating capacity of the space. The International Fire Code, portions of which have been adopted by many jurisdictions, is directed more towards the use of a facility than the construction. It specifies, "For areas having fixed seating without dividing arms, the occupant load shall not be less than the number of seats based on one person for each 18 inches (457 mm) of seating length". It also requires that every public venue submit a detailed site plan to the local fire code official, including "details of the means of egress, seating capacity, [and] arrangement of the seating...." Once safety considerations have been satisfied, determinations of seating capacity turn on the total size of the venue, and its purpose. For sports venues, the "decision on maximum seating capacity is determined by several factors.
