Nearly every tent conversation we have starts the same way: someone has a guest count and wants to know which tent covers it. The honest answer is that the guest count is only half the question. Forty people seated at round tables need more than twice the ground of forty people standing with drinks, and a buffet line eats a surprising amount of floor before anyone sits down.
Here is how we size it, and what each of our tents actually holds.
The arithmetic
Work in square feet per guest. Three numbers cover almost every event:
| Layout | Per guest | Why |
|---|---|---|
| Seated at rounds | 12–15 sq ft | Chairs pull out, servers need lanes between tables |
| Seated at long tables | 10–12 sq ft | Rectangles pack tighter than rounds |
| Standing, cocktail | 6–8 sq ft | No chairs, people move around |
Then add the things that are not guests. A buffet line wants about 100 square feet. A bar and its queue, another 100. A DJ or a band takes 100 to 200. A dance floor is roughly 4 square feet per person, counting on about a third of your guests dancing at once. These add up faster than people expect — a 60-guest party with a buffet, a bar and a dance floor needs around 400 square feet before a single dinner chair goes down.
What each tent holds
Multiply it out and our range maps to guest counts like this. These are comfortable numbers, not maximums — you can always squeeze more in, but nobody enjoys the squeeze.
| Tent | Area | Seated | Cocktail | Per day |
|---|---|---|---|---|
| 12 × 12 | 144 sq ft | 10–12 | 18 | $120 |
| 20 × 10 | 200 sq ft | 16 | 25 | $180 |
| 15 × 15 | 225 sq ft | 18 | 28 | $170 |
| 20 × 20 | 400 sq ft | 32 | 50 | $250 |
| 20 × 30 | 600 sq ft | 48 | 75 | $350 |
| 30 × 30 | 900 sq ft | 72 | 110 | $550 |
The 20 × 10 is the odd one out and the one people overlook. It is long and narrow rather than square, which makes it the wrong shape for dining but the right shape for a buffet run, a bar, or a covered walkway from the house to the main tent. It is often the second tent on an order rather than the first.
Two tents usually beat one big one
If you are deciding between a 30 × 30 and a pair of smaller tents, look at your yard before your budget. Two 20 × 20s can be placed around a pool, a tree or a slope in ways a single 900-square-foot rectangle cannot. They also let you separate dining from the bar, which keeps the queue out of the seating.
Measure the flattest clear rectangle you have, then subtract two feet on every side. That is your real tent footprint.
What South Florida adds to the decision
Three local realities change the sizing:
Rain arrives sideways. An afternoon storm here does not fall neatly downwards. If your event runs through a typical summer afternoon, size up one step so guests can move to the middle when the edges get wet, or plan for sidewalls.
Heat is the real enemy. A tent is shade, not cooling — under canvas with no air movement it can sit warmer than open shade. If your event is between noon and 4pm, budget for airflow along with the tent: a 12,000 BTU unit at $80 handles a 20 × 20 reasonably, and the 18,000 BTU at $140 is the one for a 20 × 30 or larger. There is more on this in our guide to keeping guests cool at an outdoor party.
Not every surface takes stakes. Grass is straightforward. Concrete, pavers and podium decks need weighted ballast instead, which takes more room around the perimeter. Tell us the surface when you book and we will bring the right anchoring.
When you need a permit
Rules vary by city across Miami-Dade, Broward and Palm Beach, and they usually turn on size, whether the tent has sides, and whether it is on residential or commercial property. Larger tents on commercial sites are the ones most likely to need sign-off from the local fire marshal. For a backyard party a permit is rarely in play; for a 30 × 30 at a venue or a business, ask the venue first — they will normally know their own requirement.
The short answer
For a seated dinner, take your guest count, multiply by 15, and add 300 square feet for a bar, buffet and dance floor. For a standing party, multiply by 8. Then round up to the next tent we list. If you are on the line between two sizes, take the larger one — the extra cost is small next to a party where nobody can get past the buffet.
All six tents are on the shop with prices, or call and describe the yard. We have set up in most of them.
