Cooktop Dimensions – SureFit Dimensions

A drop-in cooktop is defined by its countertop cutout — the width × depth opening cut into the counter. It varies by model even at the same nominal size, and a half-inch off can’t be undone in a stone counter. Here are the typical openings and every cooktop we’ve measured from the manufacturer spec sheet.

What decides a cooktop fit

Nominal width	Typical counter cutout (W × D)
30″	~28¾ × 19–20½″
36″	~34¾ × 19–20½″

The cutout is smaller than the cooktop’s glass or frame, which overhangs the opening — template from the exact model’s spec sheet. The full method, fuel types and OTR-microwave clearance are in range & cooktop dimensions.

Frequently asked

What size cutout does a 30-inch cooktop need?

Typically about 28¾″ wide and 19–20½″ deep — but it varies by model, so cut to the exact spec sheet, which we link on each model page.

Is the cutout the same as the cooktop size?

No — the counter opening is smaller than the cooktop’s glass or frame, which overhangs the cut. A 30″ cooktop needs roughly a 28¾″-wide cutout.

Can I drop a new cooktop into my old cutout?

Only if the openings match — cutout sizes vary by brand and model. Measure your opening and check it against the new cooktop’s spec sheet before you buy.
