A cooktop is a countertop cutout plus clearances; a range top is its beefier front-control cousin. Tell me the space and fuel, and I'll tell you what fits and what the installer will ask about.

How this works: Cooktops are sold by nominal width (12/15/24/30/36) but installed by the cutout template, typically an inch or two narrower. Range tops (30/36/48) slide in with front controls, stand taller than the counter, and cut deeper toward the wall. Side clearances and the gap to an oven below are model-specific. Always confirm final numbers against the manufacturer's installation guide before you order.
