Frequently asked questions
At round banquet tables (12 sq ft per guest) plus 20% for a dance floor and buffet, 100 guests need about 1,440 sq ft — a 40 × 40 ft tent is the smallest standard fit.
Published planning standards: about 12 sq ft per guest at round tables, 10 at rectangular banquet tables, 8 for ceremony rows and 6 for standing or theatre seating.
Round tables are space-hungry: a 60-inch round seats 8 but needs circulation room on all sides. Rows of chairs pack guests at roughly half the area per person.
Dance floors (about 3 sq ft per dancing guest), buffet lines, a bar, DJ or band, gift and cake tables, and the head table. The extra-space percentage covers them.
Yes — if no single standard size fits, rental companies combine tents with gutters. The calculator flags that once you pass 60 × 120 ft.
Allow at least 5–10 ft beyond the tent footprint on every side for stakes and guy lines (frame tents need less), plus clear access for delivery.
