A cooktop can help you cook the way you want in your kitchen with a layout that makes sense for you. Get the functionality of a stovetop without the bulk of an oven for more installation flexibility. Whether you’re replacing an old cooktop or switching up your kitchen layout with a remodel, it’s important to understand cooktop sizes. 

Our guide can help you sort through the different cooktop sizes and learn more about how to measure for a cooktop so you get the right fit the first time.

What are common cooktop sizes?

Standard cooktop sizes often correspond to common cabinet widths: 30" and 36". But, cooktops can range from a slim 15" - 24", to larger 45" and 48" wide models depending on the number and size of burners, amount of trim and more. There are also choices in the number of burners—like these 2-burner, 4-burner or 5-burner cooktop options from Whirlpool brand. When selecting your size, make sure to allow for countertop space on either side. 

Whirlpool brand offers a range of cooktop sizes to fit everything from small, apartment kitchens to large islands the whole family can gather around.

What is the difference between cooktop dimensions and cooktop cutout dimensions?

The appliance dimensions of a cooktop are not the same as the cutout dimensions needed to install it. The appliance dimensions, shown in the above image, are the length and width of the cooktop surface that sits above your countertop. The cutout dimensions are the length and width of the opening in the countertop needed for installation. Cutout dimensions are always smaller than the appliance dimensions because cooktop surfaces extend beyond the cutout below for a more seamless integration with your countertops. 

It’s important to note that cutout dimensions can vary from model to model, even among cooktops with the same appliance dimensions. For example, a 30" cooktop model from one brand can have a cutout dimension that differs from another 30" cooktop model. Although this variation is usually no more than 1½", it’s enough to affect whether a new model will fit an existing cutout. That’s why it’s important to know both dimensions when shopping for a new cooktop, even when you’re replacing an old cooktop with the same surface dimensions.

How to measure cooktop size

If you just want to replace your existing cooktop without renovations, measure both the existing appliance surface, and the size of the cutout to find a match. If you’re completing a kitchen renovation, check the appliance dimensions and the size of the cutout needed to make sure you have the right countertop space to add the cooktop you want.

Measuring for cabinet installation

Cooktops are a great option for kitchen islands, but if you’re installing a cooktop against a wall or between cabinets, you’ll want to make sure you have enough clearance to do so. The installation requirements for your specific cooktop model may vary and your product literature should be your primary source of information. Make sure to reference the installation instructions or product guides for your appliance to review the required clearances between the cooktop and cabinets, walls or other combustible materials. Here are some additional clearances you will need to consider:

What else should I consider before buying a cooktop?

In addition to a range of sizes, cooktops are available with a variety of options and features to fit your needs:

Fuel type

You can find gas or electric cooktops in a range of sizes to suit your favorite cooking style. Check your existing setup, or the requirements to install a new one to choose the best option for your kitchen. If either one will work for your space, learn more about the differences between gas and electric cooking appliances to find the right fuel source for you. Once you know which fuel source is best for you, browse gas cooktops or electric cooktops from Whirlpool brand. Also, take a look at our induction cooktops, or full selection of cooktops.

Number and size of burners

The number and size of burners or heating elements is an important consideration to help you choose a cooktop that fits both your space and your cooking needs. A standard cooktop will usually feature 4 burners in various sizes to fit a range of pots and pans. Space-efficient two-burner cooktops let you fit a cooking surface just about anywhere. For full family meals, five-burner cooktops allow you to simmer, sautee and boil all at once. Whirlpool brand even offers a cooktop featuring a removable griddle to help you sear steaks, cook pancakes, grill vegetables and more.

Features and settings

Cooktops often come with many of the same features you’d find on a range stovetop. Electric cooktops featuring smooth glass or ceramic tops are often considered the easiest to clean. Learn how to clean a glass electric stovetop to maintain it after every use. If you’re looking for convenient cleanup but prefer cooking with gas, select Whirlpool^® cooktops feature EZ-2-Lift™ hinged, cast-iron grates that provide instant access to the cooktop to quickly clean up splatters and spills. For extra flexibility, look for dual burners or dual heating elements to fit small and large pots alike.
