How big is a standard cooktop?#
A standard cooktop drops into a countertop cutout, with overall widths of 24, 30, or 36 inches and a depth around 20 to 21 inches. The table below pairs each nominal width with its exact cutout width so you can size the hole in your counter.
Standard cooktop dimensions by configuration#
| Configuration | Overall width (in) | Cutout width (in) | Depth (in) | Best for |
|---|---|---|---|---|
| 30-inch cooktop | 30 | 28.75–29.75 | 21 | the most common four-burner layout |
| 36-inch cooktop | 36 | 34.75–35.75 | 21 | five burners and big cookware |

Installation clearances for a standard cooktop#
- Cutout depth: 18–21 in in of countertop cutout depth a cooktop needs, set back far enough to clear the front edge.
- Below-counter clearance: 3–5 in in the cooktop body drops below the countertop, so leave that room above a drawer or oven.
- Side clearance: 12–15 in in of countertop the manufacturer wants beside a cooktop to a wall for safe pan handling.
Will your standard cooktop fit? Clearances and door swing#
A cooktop's fit is all about the countertop cutout, which is slightly smaller than the overall width so the unit's edge rests on the counter. A 30-inch cooktop needs a cutout 28.75 to 29.75 inches wide; a 36-inch needs 34.75 to 35.75 inches; and a 24-inch needs 21 to 22 inches — always confirm against the model's template. Plan a cutout depth of 18 to 21 inches, leave 3 to 5 inches of clearance below the counter for the unit's body and any downdraft, and keep 12 to 15 inches of countertop on each side to a wall for safe workspace. Measure the counter depth so the 20-to-21-inch body clears the cabinet front.

Standard cooktop sizes by type: 30-inch cooktop, 36-inch cooktop, 24-inch cooktop#
The three cooktop widths suit different kitchens. A 30-inch cooktop, with a 28.75-to-29.75-inch cutout and 21-inch depth, is the standard four-to-five-burner choice for most kitchens. A 36-inch cooktop, needing a wider 34.75-to-35.75-inch cutout, adds a fifth or sixth burner and more room between pots for serious cooking. A 24-inch cooktop, with a compact 21-to-22-inch cutout and 20-to-21-inch depth, fits an apartment, island, or secondary prep zone. All three need 3 to 5 inches of clearance below the counter and 12 to 15 inches of side workspace.
