Built-in Outdoor Gas Grill Sizes and Dimensions | Cutout Rules

For the full breakdown, see our best Built-In Outdoor Gas Grills guide.

Built-in outdoor gas grill sizes and dimensions don’t follow one universal standard—brands and models vary widely, which is exactly why so many outdoor kitchen builds go wrong. The most common built-in widths for US outdoor kitchens fall between 30 and 36 inches, though many homeowners choose larger 34–40 inch models for serious entertaining. Before you buy anything, the real question isn’t just width—it’s whether the grill head will actually fit the cutout you’re building or replacing. For a tested look at top-performing models, our roundup of the best built-in outdoor gas grills covers the standouts worth your money.

What Sizes Do Built-In Gas Grills Come In?

Built-in gas grills generally cluster into four width bands, and knowing where your needs land narrows the field fast. The 30–32 inch range is a common standard for compact outdoor kitchens. The 34–40 inch band is what many guides describe as the range “most people choose” for a balance of cooking space and island footprint. Large 41–48 inch models suit serious entertaining, while 50–56 inch units are essentially professional-grade cooking suites.

Cooking area scales with width, but not linearly. Standard grills typically offer 400–500 square inches of cooking space, while large models jump to 550 square inches and beyond—some hitting 600–700 square inches.

Real Dimensions From Spec Listings

Actual dimensions vary enough that you can’t assume a “36-inch” grill is actually 36 inches wide. Here’s how real listings break down:

• 24-inch model: 24 in. W x 18 in. H x 23-3/4 in. D
• 27-inch model: 27 in. W x 24-3/8 in. H x 24-3/4 in. D
• 36-inch model: 35-7/8 in. W x 22 in. H x 25-3/8 in. D
• 48-inch model: 47-7/8 in. W x 22 in. H x 25-3/8 in. D
• Cart-style built-in example: 60 in. W x 24 in. D x 48 in. H

Notice the pattern: a 36-inch model measures just shy of 36 inches wide, and height and depth vary between models regardless of width. Height commonly sits around 22–24 inches for the grill head itself, while depth runs 23–26 inches—but these shift by brand and design.

Measuring the Cutout: The Step Order That Works

The biggest mistake in outdoor kitchen builds is confusing the grill’s exterior dimensions with the cutout requirements. Measure the opening itself, not the grill box, because a built-in grill must match the cutout width, depth, and height exactly—not just look right from the front.

1. Width: Measure the cutout slot where the grill head will sit, from one interior edge to the other.
2. Depth: Measure from the island’s front edge back to where the grill’s rear will align.
3. Height: Measure how far down the grill head will sit, accounting for the control panel height and any drip pan or protruding components below.
4. Cut once: Confirm every measurement twice before making any cuts—the standard advice “measure twice, cut once” exists for exactly this reason.

Clearance adds another layer. Good Housekeeping’s outdoor grill testing confirms that performance and fit vary meaningfully between models, so the spec sheet is your final authority.
