About Seating Capacity Of A Hall Calculator

Each layout has a published area per person, and capacity is the usable area after deducting aisles and stage divided by that figure. Layout dominates capacity: the same hall seats more than twice as many theatre style as it does at banquet rounds, which is why the layout is chosen before the guest list.

Formula

Capacity

seats = floor(area x (1 - circulation share) / area per person)
