An Introduction to Cooktop Dimensions
Understanding Cooktop Dimensions
A cooktop gives you the freedom to cook the way you want with a layout that suits your needs. With the functionality of a stovetop without the weight of an oven, you can install it more conveniently. Whether you’re replacing an old cooktop or switching up your kitchen layout with a remodel, it’s important to know the size of cooktops.
In our guide, we explain the various cooktop sizes and how to measure for a cooktop so you get the ideal fit the first time.
What Are Common Cooktop sizes?
Cooktop sizes generally match common cabinet widths: 30” and 36”. But, cooktops can range from a slim 15” - 24” to larger 48” wide models depending on the number and size of burners, amount of trim, and more. Be sure to allow sufficient space on both sides of your countertop when choosing your size.
KitchenAid offers a range of cooktop sizes to suit any kitchen, whether it's a compact apartment kitchen or a large family kitchen island.
What is the Difference Between Cooktop Dimensions and Cooktop Cutout Dimensions?
Cooktop appliance dimensions differ from the cutout dimensions necessary to install them. In the image above, you can see the appliance measurements, which 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 keep in mind that cutout dimensions vary from model to model, even within the same appliance size range. 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 1 ½”, it’s enough to affect whether a new model will fit an existing cutout. That's why both dimensions are important to look at when shopping for a new cooktop, even if it's a replacement for an old one with the same surface dimensions.
How to Measure For the Right Cooktop Size
In case you just wish to replace your existing cooktop without renovations, measure both the existing appliance surface and the cutout to make sure the new cooktop will fit.
When you renovate a kitchen, check the appliance dimensions and the size of the cutouts needed to make sure you have enough countertop space to add the cooktop you want.
How to Replace a Cooktop
1st Step: Measure Your Existing Appliance
To get the most accurate measurements, uninstall your cooktop first.
Depth: Measure the front-to-back depth of the cooktop surface, including the control panel.
Width: Measure the width of your existing cooktop by running a tape measure from the right outer edge to the left outer edge of the cooktop surface.
2nd Step: Measure the cooktop cutout:
Depth: Measure the distance between the front edge of the cutout and the back edge. Take two measurements: one closer to the right side, another closer to the left side. Use the smaller measurement.
Width: Measure the width of the cutout from the right edge to the left edge using a measuring tape. To ensure accuracy, take a measurement near the front of the cutout, and another measurement near the back of the cutout. Always use the smallest dimension.
Cabinet Installation
Having a kitchen island with a cooktop is a great option, but if the cooktop will be installed against a wall or between cabinets, you will need to have enough clearance. The installation requirements for your particular cooktop may differ, so make sure you consult your product literature as your primary resource. For details on the clearance requirements between the cooktop and cabinets, walls, or other combustible materials, refer to your appliance's installation instructions or product guide. Here are some additional clearances you will need to keep in mind:
- Space above the cooking surface: Determine the minimum clearance needed between the cooking surface and the bottom of cabinets or other combustible surfaces.
Note: This will depend on whether or not you include a range hood or vent. If using, follow the hood or vent installation instructions for dimensional clearances above the cooking surface. - Upper cabinet dimensions: Measure the size of the upper cabinets on either side of the cooktop. Be sure to take the cabinet depth into account, as well as the distance between each cabinet and the countertop.
- Distance between cooktop and wall: The surface of the cooktop to a wall or other combustible material also requires a minimum clearance. Always refer to your installation guide for detailed directions.
Buying a Cooktop: What Else Should I Consider?
Fuel Type
You can choose from gas, radiant electric, and induction cooktops in a range of sizes to suit your favourite cooking style. Check your current setup or the requirements to install a new one to choose the most suitable 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. After you determine which fuel source is best for you, browse gas cooktops or electric cooktops from KitchenAid.
Number and Size of Burners
You should consider the number, size, and type of burners or heating elements on your cooktop when choosing one that will fit your kitchen space and needs. Cooktops typically have four burners of varying sizes that can accommodate a variety of pots and pans. Space-efficient two-burner cooktops make it easier to fit a small cooking surface just about anywhere. For full family meals, five-burner cooktops allow you to simmer, sautee, and boil all at once. KitchenAid even offers a cooktop featuring a removable griddle that allows you to cook pancakes, grill vegetables, or even sear steaks.
Features and Settings
Most cooktops come with similar features as a range stovetop. Tops that are smooth, electric or induction, and either made of glass or ceramic, are often the easiest to keep clean. If you’re looking for convenient cleanup but prefer cooking with gas, select KitchenAid® cooktops with a removable griddle feature that provides instant access to the cooktop to clean up splatters and spills quickly. Consider buying a cooktop with warm zones if you tend to prepare multi-course dinners often. You can keep your food warm while the rest of the meal is being prepared.
