Range & Cooktop Dimensions: Standard Sizes and Cutouts
The overwhelming majority of ranges are 30″ wide, and most cabinetry is cut for exactly that. The numbers that trip people up are the cooktop cutout (smaller than the appliance) and the clearance above it. Here are the standard sizes and the openings they need.
Standard range widths
A range combines the cooktop and oven in one freestanding or slide-in unit. Width is the dimension your cabinets are built around; depth and height are fairly consistent across the category.
| Nominal width | Where you see it | Typical depth |
|---|---|---|
| 24″ | Apartments, compact kitchens | 24–26″ |
| 30″ | The standard for most kitchens | 25–29″ |
| 36″ | Pro-style and larger gas ranges | 26–29″ |
| 48″ | Pro / dual-fuel ranges | 27–30″ |
Standard counter height is 36″; freestanding and slide-in ranges are built to sit flush with it. Leave the manufacturer’s required clearance to combustibles on the sides — usually 0″ to the counter but a specified gap to any side wall.
Slide-in vs freestanding
A freestanding range has finished sides and a rear control panel; it can stand alone or drop between cabinets. A slide-in has unfinished sides and front controls, and it’s designed to nest between counters for a built-in look with the countertop overlapping its edges. They share the same nominal width, but a slide-in usually needs the countertop cut to its spec — check the model sheet before the counters are templated.
Cooktop cutout dimensions
A drop-in cooktop is larger than the hole it sits in — the published cutout is what your fabricator needs, and it varies by model even at the same nominal size. Always cut to the specific model’s sheet; the figures below are only typical.
| Nominal cooktop | Typical cutout width | Typical cutout depth |
|---|---|---|
| 30″ | 28¾–29″ | 19–21″ |
| 36″ | 34¾–35″ | 19–21″ |
Cut to the model, not the nominal size
Two 30″ cooktops can call for cutouts that differ by half an inch. A cutout that’s too big can’t be undone in a stone counter — template from the spec sheet of the exact model you bought.
Pairing a separate cooktop with a built-in oven below or in a tower? The oven has its own cabinet opening — see wall oven dimensions & cutouts.
Over-the-range microwave clearance
An over-the-range (OTR) microwave replaces the hood, so two clearances govern it: the gap above the cooking surface and the mounting height. Most manufacturers and codes call for a minimum of 30″ between the cooktop and the bottom of the microwave (some models are listed for as little as 13–18″ — check the label), with the cabinet above typically at 30″ and the unit’s top around 66″ from the floor.
