Banquet Room Capacity Calculator
Estimate the maximum number of guests your banquet room can accommodate based on room dimensions and seating arrangement style.
Formulas Used
Gross Area = Length (ft) × Width (ft)
Usable Area = Gross Area − Unusable Area
Maximum Capacity = ⌊ Usable Area ÷ Space per Person ⌋
Comfortable Capacity = Maximum Capacity × 0.80
| Seating Style | Sq Ft / Person |
|---|---|
| Banquet / Round Tables | 11 |
| Reception / Cocktail Standing | 6 |
