Figure Out Your Headcount First
Everything else flows from this. Your headcount determines your tent size, table and chair count, food quantities, and overall logistics. Get a realistic number early — and then add 10% for last-minute additions.
A general rule for outdoor seated events:
- Seated meal at rectangular tables: 6–8 people per 8-foot table
- Casual picnic-style seating: 8–10 people per picnic table or similar
- Mix of seated and standing/lawn areas: Budget about 15 square feet per person under the tent
For a group of 100 employees, you're typically looking at 12–14 eight-foot tables, 100 chairs, and a tent in the 30x60 or 40x60 range depending on your layout and whether you're including a food station or activity area inside.
