What Size Grill for a Party of 10? 400 Sq In in Two Rounds
Quick answer
Ten guests cooked in two rounds need about 400 square inches of primary cooking area, a 3 or 4-burner grill. Cooking for all ten at once needs about 800 square inches, a 5 or 6-burner. Most hosts cook in rounds, so a 500 to 570 square inch grill handles a party of 10 comfortably.
Party sizing has two honest answers and the difference between them is how you like to host. Cooking in rounds means about 40 square inches per guest, because half the food is on the grill while the other half is being eaten. Cooking everything at once means the full 80 square inches per guest, which doubles the grill you need to buy.
The grill size calculator takes both your everyday household and your biggest group and returns the larger, so you can see which one is actually driving your purchase.

What size grill do I need for a party of 10?
| How you cook | Area needed | Burners | Grill class | Rounds |
|---|---|---|---|---|
| Two rounds, the usual way | 400 sq in | 2 to 3 | 3-burner full-size | 2 |
| Everything at once | 800 sq in | 4 to 5 | 5 or 6-burner | 1 |
| Burgers and dogs only, in rounds | 320 sq in | 2 to 3 | 3-burner full-size | 2 |
| Steaks and chops, in rounds | 480 sq in | 3 to 4 | 4-burner full-size | 2 |
Based on 80 square inches per person, halved when a group is cooked in rounds. Burgers and dogs pack tighter than steaks, which is why the food type changes the answer. Primary cooking area is the grate directly over the burners. Warming racks add to a total area figure but run cooler and do not count toward the numbers here.
How many burgers can I cook at once for a party?
| Primary area | Burgers at once | Hot dogs at once | Chicken breasts | Steaks |
|---|---|---|---|---|
| 400 sq in (3-burner) | 16 | 50 | 13 | 8 |
| 500 sq in (4-burner) | 20 | 62 | 16 | 11 |
| 570 sq in (5-burner) | 22 | 71 | 19 | 12 |
| 750 sq in (6-burner) | 30 | 93 | 25 | 16 |
At 25 square inches per 4 inch patty, a 400 square inch grill puts 16 burgers on at once, which feeds ten guests in one and a half rounds. Counts assume the full grate is in use with no indirect zone.

How do I time a cookout for ten people?
- Decide rounds before you shop. If you are happy serving in two waves, 400 square inches is enough. If everyone must eat at once, you need about 800, which is a different grill entirely.
- Cook the slow food first. Bone-in chicken and thick chops go on first over an indirect zone, then burgers and dogs on the hot side while they finish.
- Keep a holding zone. Leave one burner off or use the warming rack so finished food stays hot while the next round cooks. This is the difference between rounds and chaos.
- Use a side burner or a griddle for the extras. Onions, peppers and sauces belong off the main grate, which frees the whole primary area for mains.
- Check the tank before guests arrive. Weigh the tank or use a gauge. Running out halfway through a party is the most common cookout failure, and a spare tank costs less than the food does.
- Pull food by temperature, not by time. An instant-read thermometer keeps chicken safe and steaks where people ordered them when you are cooking twenty pieces at once.
Should I add a griddle instead of a bigger grill?
For a party of 10 it is often the better buy. A 36 inch griddle gives 768 square inches of flat surface, more than any cart grill in our catalog, and nothing falls through, so smash burgers, onions, peppers and even breakfast for a weekend crowd all work. Paired with a three or four burner grill you get more total capacity than a six-burner, usually for less money.
The Blackstone 36 in. Original Griddle with Built-in Hood ($539.99) is the common choice, and the trade-offs against a grill are laid out in griddle vs gas grill. If you would rather have one big grill, the Broil King Regal S 690 Pro IR Gas Grill (Propane) at 750 square inches of primary area is the catalog's largest freestanding option, and the case for it is made in what size grill for a party of 20. Kits with tank, cover and tools are in the intermediate outdoor cooking setup.
Which grills should I buy for regular parties of ten?
Four to six burners, or a four-burner plus a griddle. More in the best gas grills and the best flat top griddles.

$1,174.00570 square inches of primary area and 780 total across five burners, which covers a party in two comfortable rounds with a holding zone that keeps the first round hot.

Frequently asked questions
What size grill do I need for 10 people?
About 400 square inches of primary cooking area if you cook in two rounds, which most hosts do, and about 800 square inches if everything has to be ready at once. In practice a 500 to 570 square inch four or five burner grill handles a party of ten comfortably, with one burner left off as a holding zone for the first round.
How many burgers can you cook on a 4-burner grill?
About 20 at once on a 500 square inch primary grate, at 25 square inches per 4 inch patty with room to flip. That is two rounds for a party of ten with a burger each and extras. If you keep part of the grate as an indirect zone, count on about two thirds of that, which is still 13 or 14 patties per round.
Is a griddle better than a grill for a party?
For volume, often yes. A 36 inch griddle gives 768 square inches where nothing falls through, so patties, onions and peppers can be packed edge to edge, and that is more capacity than any cart grill in our catalog. A grill still wins on thick steaks, bone-in chicken and anything you want char marks on. Many hosts end up with both.
How much propane does a party of ten use?
It depends on burner count and cooking time rather than on guest numbers, and the honest answer is to measure rather than guess: weigh the tank or fit a gauge before the party. A spare 20 lb tank is the standard insurance, since running out mid-cook is far more disruptive than the cost of the second tank.
