Work out event space capacity instantly with clear inputs, formula shown and shareable results.
Event capacity is net usable area divided by the area per person that the layout requires. Banquet rounds need roughly twice the area per person of theatre seating, and circulation, staging and service routes typically absorb a further 20-30% of the room.
Net usable area
Net area = (Floor area - Obstructed area) x (1 - Circulation allowance %)
Capacity
Capacity = Net usable area / Area per person for the layout
Yes, always. Licensed capacity and exit width requirements are absolute limits regardless of what the area calculation permits.
Because tables are only partly seated to keep sightlines to the stage clear, so the same table serves fewer guests.
