6 Burner Gas Grill vs 5 Burner: Which Is Right for You?

Deciding between a 6-burner gas grill vs 5-burner comes down to how many people you cook for and how much space you want to fill. For a family of four to six, the 5-burner usually cooks everything you need with a smaller footprint and lower fuel consumption. For regular parties or two-zone cooking at scale, the extra burner earns its keep.

What Changes With The Sixth Burner

The sixth burner adds more than one more flame — it increases total cooking surface and, in most configurations, a higher total BTU output. Those extra inches matter when you’re searing steaks on one side while chicken finishes on the other.

Burner count alone doesn’t tell the whole story. That’s because burner size, grate spacing, and heat distribution shape performance just as much as the count. A 5-burner with better layout can out-cook a cramped 6-burner with identical burners.

5-Burner Models: Plenty For Most Cooks

A 5-burner gas grill handles a standard household cookout without excess.

That’s still room for a dozen burgers, a full rack of ribs, or a couple of whole chickens, with a side burner rated at 10,000 BTUs for sauces or a pot of corn. The smaller footprint fits tighter patios and weighs less to move. If you grill two or three times a week for the family, the 5-burner saves propane without sacrificing much real capacity.

6-Burner Grills: Capacity And Heat Zones

Go 6-burner when you regularly cook for eight or more, or when you want separate temperature zones running at once. A 540–555 sq. in. primary area fits more food in a single pass, and the higher total output recovers heat faster after the lid opens. The Char-Broil 463228622 and 463229521 models both carry 54,500 total BTUs, with a 10,000 BTU side burner and electronic ignition.

One caution: specs vary by retailer even within the same series. Always verify the full model number before you buy or order replacement parts. If you’re narrowing down options, our tested roundup of the best 6 burner gas grills covers the top performers side by side.

FAQs

Do you need a side burner on a gas grill?

A side burner is worth having if you frequently cook sides, simmer sauces, or boil corn while the main grates are full. The Char-Broil models listed here include a 10,000 BTU side burner, which handles a standard saucepan comfortably. If you rarely cook sides outdoors, the extra burner just adds cleaning and surface area.

Does more BTU mean better grilling?

Higher BTUs do not automatically mean better food. BTUs measure heat output, but grate design, burner placement, and even heat distribution matter more for consistent cooking. A 5-burner grill with 37,500 main-burner BTUs can sear as well as a 6-burner with 32,500 BTUs if its layout spreads heat evenly across the cooking surface.

Is a 6-burner grill too big for two people?

For just two people, a 6-burner grill is usually more than you need. It burns more propane, takes up more patio space, and takes longer to preheat a large surface for small meals. A 4- or 5-burner model gives you enough room for a couple’s weekly cooking while keeping fuel costs and footprint manageable.
