A Guide to Cooktop Dimensions

Are you looking to upgrade your kitchen with a cooktop? Knowing their measurements is crucial. Our guide can help you get started.

What is the Difference Between Cooktop Dimensions and Cooktop Cutout Dimensions?

A cooktop's appliance dimensions differ from the dimensions of the cutout 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. In most cases, cutout dimensions are 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 differ among models, 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 1 ½”, it’s enough to affect whether a new model will fit an existing cutout. So knowing both dimensions is essential when shopping for a new cooktop, even if it's just a replacement for an old cooktop with the same dimensions.

How to Measure Cooktop Size

If you are looking to replace only your existing cooktop without making renovations, measure your existing surface and the cutout to find a match.

To ensure you have enough counter space for your desired cooktop, check the appliance dimensions and the size of the cutout needed before completing a kitchen remodel.

Replacing an Existing Cooktop

Step 1: Take measurements of your existing appliance

To make sure that you get accurate measurements, first uninstall your cooktop.

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. 

Depth: Measure the front-to-back depth of the cooktop surface, including the control panel. 

Step 2: Measure the cooktop cutout: 

Width: Measure the width of the cutout from the right edge to the left edge using measuring tape. Be sure to measure the cutout from the front and back, in order to ensure accuracy. Always go with the smallest dimension.

Depth: Measure from the front to the back of the cutout. Take two measurements: one closer to the right side, another closer to the left side. If there’s a difference, use the smaller dimension.

Cabinet Installation Instructions

Choosing a cooktop for your kitchen island can be a great choice, but if you intend to install it against a wall or between cabinets, you'll want to ensure you have sufficient clearance. You should always consult your product documentation for installation details specific to your cooktop model. Make sure to check your appliance's installation instructions or product guide to determine how much space you need between your cooktop and cabinets, walls, or other combustible materials.

Consider the following clearances as well:

• Upper cabinet dimensions: Measure the size of the upper cabinets on either side of the cooktop. Consider both cabinet depth and the distance from the cabinets to the countertop. 
• Space above cooking surface: Check minimum clearances needed from the cooking surface to the bottom of cabinets or other combustible surface.
  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.
• Distance between cooktop and wall: The surface of the cooktop to a wall or other combustible material also requires a minimum clearance.  Always check your installation guide for installation instructions specific to your unit.

Other Factors to Consider Before Purchasing a Cooktop?

Along with a variety of sizes, cooktops can be customized with various options and features:

Fuel Type
You can choose from gas, radiant electric, and induction cooktops in different sizes to suit the way you like to cook. For the best option for your kitchen, check your existing setup or what is required for a new one. Once you know which fuel source is best for you, browse gas cooktops or electric cooktops from Whirlpool.

Size and Number of Burners
In order to choose a cooktop that fits your space and your cooking needs, you will need to consider the number of burners and the size of the elements. A standard cooktop will usually feature four 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. When cooking for a family, a five-burner cooktop allows you to simmer, saute, and boil simultaneously. Whirlpool even offers a cooktop featuring a removable griddle that can be used for grilling, grilling, and even searing meat.

Features and Settings
Many features found on stovetops can also be found on cooktops. Smooth glass or ceramic tops that are either radiant electric or induction are often considered the easiest to clean. 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. If you often prepare multiple dishes at once, look for a cooktop that has warming zones to help keep food warm while the rest is being prepared.
