How big is an induction cooktop?#
An induction cooktop is 30, 36, or 24 inches wide overall, with cutouts of 28.75 to 29.75, 34.75 to 35.75, or 21 to 22 inches. Depths run 19 to 21 inches. The table below matches each width to its cutout, and the clearances cover the cooling fan's needs below the glass.
Induction cooktop dimensions by configuration#
| Configuration | Overall width (in) | Cutout width (in) | Depth (in) | Best for |
|---|---|---|---|---|
| 30-inch four-element induction | 30 | 28.75–29.75 | 20–21 | the most common flush glass layout |
| 36-inch five-element induction | 36 | 34.75–35.75 | 20–21 | big pans and a bridge zone |
| 24-inch two-element induction | 24 | 21–22 | 19–20 | a small kitchen or an island prep zone |

Installation clearances for an induction cooktop#
- Cutout depth: 18–20 in in of countertop cutout depth an induction cooktop needs, set back to clear the front edge.
- Below-counter clearance: 3.5–4 in in the induction cooktop body and its cooling fan drop below the countertop.
- Ventilation gap: An induction cooktop needs an open air path to its underside cooling fan, so avoid a sealed drawer directly beneath it.
- Side clearance: 12–15 in in of countertop the maker wants beside an induction cooktop to a wall for safe pan handling.
Will your induction cooktop fit? Clearances and door swing#
An induction cooktop drops into a countertop cutout like any other, but its cooling fan changes what happens below. Cut the opening 18 to 20 inches deep, set back to clear the front edge, and match the cutout width to your model. Under the counter, the body and its fan drop 3.5 to 4 inches — less than a gas burner box — but that fan needs an open air path to breathe, so do not seal a drawer directly beneath the unit. The maker also wants 12 to 15 inches of countertop beside the cooktop to a wall for safe pan handling, which is a working-room clearance rather than a heat one, since induction heats the pan and not the surrounding air. Confirm the cutout depth, leave the fan an air path, and keep the side counter clear before you set it.

Induction cooktop sizes by type: 30-inch four-element induction, 36-inch five-element induction, 24-inch two-element induction#
The 30-inch four-element induction is the most common flush glass layout, using a 28.75-to-29.75-inch cutout and a 20-to-21-inch depth — the default for a modern kitchen. The 36-inch five-element widens the cutout to 34.75 to 35.75 inches and typically adds a bridge zone, so a griddle or a big roasting pan can span two elements. The 24-inch two-element is the compact option at a 21-to-22-inch cutout and a shallower 19-to-20-inch depth, ideal for a small kitchen or a secondary prep zone on an island. All three share the same below-counter fan clearance and the same side working room, so the choice is cooking width: 30-inch for a standard kitchen, 36-inch for big pans and a bridge, and 24-inch for a tight or secondary surface.
