What size tent do I need for 100 guests?

For a seated meal, about 1,200 square feet, such as a 30 by 40 ft tent. Standing guests need about half that, such as a 20 by 30 ft tent. Add room for a buffet, bar or dance floor.

How many tables do I need for 100 guests?

With 60 inch round tables that seat 8, you need 13. With 6 ft banquet tables that seat 6, you need 17. Add tables for food, drinks, gifts and the cake.

How far ahead should I book party rentals?

For tents and large orders on weekends in spring, summer and the holidays, book a couple of months ahead. Small orders can often be booked a few weeks out.

Do I need a permit for a party tent?

Often not for a small tent on your own property. Larger tents (many places draw the line at about 400 square feet) and tents in parks or on streets may need a permit. Check with your city or fire department.

Guide

Party rental checklist: tents, tables, chairs and bounce houses

Start with two numbers: how many guests, and whether they will sit down to eat. Those set the tent size, the tables and the chairs. This checklist walks through each one, adds bounce house space and safety, and gives a simple timeline so nothing is missing on the day.

By the findpartyrental team. Updated October 5, 2026. General guidance only; check the rules where you live.

Tent size by guest count

The rule most planners start with: about 6 square feet per standing guest and 10 to 12 square feet per seated guest at tables. Our planner uses 12 for a seated meal, which leaves room for chairs to push back and people to walk between tables.

Guests a tent holds before you add a buffet, bar, dance floor or stage. Rounded down.
Tent size	Area	Seated at tables	Standing
10 by 10 ft	100 sq ft	8	16
20 by 20 ft	400 sq ft	33	66
20 by 30 ft	600 sq ft	50	100
20 by 40 ft	800 sq ft	66	133
30 by 40 ft	1,200 sq ft	100	200
40 by 60 ft	2,400 sq ft	200	400
40 by 80 ft	3,200 sq ft	266	533

Then add space for everything that is not a guest: buffet and drink tables, a bar, the cake, a DJ or band, and a dance floor. Ask the rental company to sketch a floor plan; most will.

Which kind of tent

Pop-up canopies are small and quick, good for shade over a food table or a small group.
Frame tents have no center poles, so the space inside is open. They can stand on pavement with weights.
Pole tents use center poles and are held up by stakes driven into the ground, so they need a lawn or soft ground.

Ask about sidewalls in case of wind, rain or cold, and about lighting if the party runs past sunset.

Tables and chairs math

Chairs: one per guest, plus a few spares. Tables: divide the guest count by the seats per table and round up. For 100 guests at 60 inch rounds that seat 8, that is 13 tables.

Floor-length cloths assume a standard 30 inch table height.
Table	Seats	Floor-length cloth
60 inch round	8 (10 if tight)	120 inch round
72 inch round	10 (12 if tight)	132 inch round
6 ft banquet	6, or 8 with one at each end	90 by 132 inch
8 ft banquet	8, or 10 with one at each end	90 by 156 inch

Then count the tables that do not seat anyone: food, drinks, gifts, the cake, a sign-in table and the DJ. Those add up quickly. The party planner works out chairs, tables and a tent size from your guest count.

Bounce houses: space and safety

Ask the rental company for the unit's footprint and how much clear space it needs around it, then check your yard against both. You will also need:

Flat ground clear of rocks, sticks, sprinkler heads and pet waste. A tarp usually goes underneath.
Open sky. No power lines or low branches over the unit.
A clear path from the street to the setup spot, wide enough for the rolled-up unit on a dolly. Measure gates.
Power. The blower runs the whole time. Ask how far the outlet can be and whether it needs its own circuit, or rent a generator.
Anchors. Every anchor point staked, or weighted with sandbags on pavement, as the company directs.

Safety rules matter more than the setup. Keep an adult watching at all times. Limit how many children are inside at once and group them by size. No shoes, glasses, sharp objects, food or gum, and no flips. Get everyone out and let the unit down when wind picks up past the manufacturer's limit, and in rain or lightning. Inflatables in the US are covered by an industry safety standard, ASTM F2374. Ask the company whether it follows it and carries insurance, and whether your state inspects inflatables.

Easy to forget

Linens and napkins, and how they come back (most companies take them back unwashed but free of food).
Lighting, extension cords and a generator if outlets are far away.
Heaters or fans, depending on the season.
Trash and recycling cans, and who hauls the bags away.
Restrooms for a long party or a big crowd.
A dance floor, so heels and chairs do not sink into the lawn.
Stakes or weights for every tent, and what happens if the weather turns.

A simple timeline

2 to 3 months out: pick the date and place, estimate guests, and book the tent and large items. Spring, summer and holiday weekends fill first. Ask your city whether a large tent or a public site needs a permit.
3 to 4 weeks out: firm up the guest count, the floor plan and the power plan. Order linens.
1 week out: confirm the delivery window, the setup spot and a phone number for the person who will meet the crew. If tents will be staked, call 811 a few business days ahead so buried utility lines get marked.
The day before: mow, mark sprinkler heads, clear the path and park cars elsewhere.
On the day: count items when they arrive and walk the setup with the crew.
After: stack chairs and tables where the company asked, note any damage, and be there or leave access for pickup.
