Direct Answer
The most common cooktop size used in American kitchens is 30 inches wide. This size fits standard countertop cutouts and provides enough cooking space for most households, making it the most widely sold option.
Larger cooktops, such as 36-inch models, are popular in custom kitchens but are far less common overall.
Why 30-Inch Cooktops Dominate
Standard cabinetry and countertops are designed around 30-inch appliances, reducing installation complexity and cost.
When Larger Cooktops Make Sense
Homes with larger kitchens or frequent cooking needs may benefit from 36-inch cooktops.
Smaller Cooktop Options
Compact cooktops are available for apartments and small kitchens but account for a smaller share of sales.
