Tent square footage guide
Add up the space for guests and for everything else under the tent, then add walking room:
Tent area = guests × sq ft per guest + dance floor + buffet + bar + stage + tables, × (1 + walking room)

| Standing cocktail party | 6 sq ft per guest |
| Ceremony / theater rows | 6 sq ft per guest |

| Seated at banquet tables | 10 sq ft per guest |
| Seated at round tables | 12 sq ft per guest |
| Dance floor | 4.5 sq ft per dancer (30–50% of guests) |
| Buffet line | about 100 sq ft per line (1 per 100 guests) |
| Bar | about 80 sq ft (1 per 75–100 guests) |
| DJ / small band / large band | 64 / 192 / 384 sq ft |

Tips for choosing a tent
- Measure the site, adding 5–10 ft around a pole tent for stakes and guy lines, and check the ground is level.
- Call before you dig (811 in the US) before stakes go into a lawn.
- Ask about local permits; many towns require a permit and fire-rated fabric for tents over a certain size.
- Plan lighting, heaters or fans and leave room for them and their cables.
- Work out the exact number of tables with the event table calculator.
Frequently asked questions
How much tent space do I need per guest?
Common planning figures are about 6 sq ft per guest standing at a cocktail party or seated theater-style in rows, 8 sq ft for a cocktail party with some tables, 10 sq ft at long banquet tables and 12 sq ft at round tables for a seated dinner. Add space for the dance floor, buffet, bar and stage on top.
What size tent do I need for 100 guests?
For 100 guests seated at round tables you need about 1,200 sq ft for seating alone, so a 30 × 40 ft tent. With a dance floor, buffet, bar, DJ, head table and cake table the total rises to about 2,000 sq ft, which calls for a 40 × 60 ft tent (2,400 sq ft) or a 30 × 60 ft tent (1,800 sq ft) if the layout is tight.
How many people fit in a 20 × 40 tent?
A 20 × 40 ft tent is 800 sq ft. It holds about 64 guests seated at round tables, 80 at banquet tables, or about 130 standing or in ceremony rows, before any dance floor, buffet or bar.
How big should a dance floor be?
Allow about 4.5 sq ft per dancer. Usually 30% to 50% of guests dance at the same time, so for 100 guests a floor of about 12 × 15 ft (180 sq ft) works for 40 dancers. Rental dance floors come in 3 × 3 ft or 4 × 4 ft panels.
What is the difference between a pole tent and a frame tent?
A pole tent has center poles and needs stakes around the outside, which makes it cheaper and elegant but means poles inside the space. A frame tent has no center poles, so all the floor space is usable and it can stand on pavement with weights. If you choose a pole tent, keep the walking-room allowance at 10% or more.
Should I rent a bigger tent in case of rain?
If rain is possible, add sidewalls and plan for activities that would otherwise be outside, such as cocktail hour or the ceremony, to move inside. Adding those areas or raising the walking-room allowance gives a tent that still works if everyone must be under cover.
