A guide to cooktop dimensions
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 how various cooktop sizes will affect your plans.
Your cooktop size may differ from the size of your appliance cutout. Cutout dimensions are typically smaller than cooktop dimensions to allow for the cooktop surface to extend beyond the cutout space and align with your countertops. This guide can help you sort through different cooktop sizes and cooktop cutout dimensions, as well as help you measure and choose 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. Then, measure the surrounding space for cooktop height clearance, measuring the upper cabinet depth and height, the height above the cooktop surface and the distance between the cooktop and wall.
You may want to start with cabinet and countertop planning first if you are doing a full kitchen remodel. This can help you decide where to place your cooktop and ensure you have enough space to install your appliance.
How to measure for a replacement cooktop
If you’re getting ready to replace your old cooktop with a new model, understanding how to measure your current space against the dimensions of your new cooktop can help ensure a perfect fit. Measure from both sides to help ensure accuracy. If there is a discrepancy between the two measurements, use the smallest dimension for a more accurate fit for your cooktop.
Use the guide below to learn how to measure for a replacement cooktop.
Step 1: Measure your existing cooktop
First, uninstall your cooktop to make sure you get the most accurate measurements.
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. To ensure accuracy, take a measurement near the front of the cutout and another measurement near the back of the cutout. Always go with the smallest dimension.
Depth: Measure from the front edge of the cutout to the back. Take two measurements: one closer to the right side, another closer to the left side. If there’s a difference, use the smaller dimension.

How to measure for a new cooktop
Begin by measuring the width and depth of where you want to place your new cooktop. You may also want to measure at least 8 ½ to 12 ⅞ inches of clearance on each side (this number may vary by model, so check your user manual for exact requirements) of the cooktop for ease of use and food prep, and at least three inches of clearance between the back of the cooktop and any walls for proper ventilation and heat dissipation. Your exact measurements will depend on the size of the cooktop, so be sure to check your dimensions guide to help get the right measurements.
Measure the cooktop cutout
Once you’ve decided on a placement for your new cooktop, you’ll want to measure where you intend to place your cooktop.
Width: Use your tape measure to find your cutout’s width, going from the right edge to the left edge. Measure twice—once at the front and another at the back—and use the smallest measurement for accuracy.
Depth: Run your tape measure from the front edge of your cutout to the back. Take two measurements, one on the right side of the cutout and another on the left, using the smallest dimension if there is a difference between the two.
Measuring for cooktop height clearance
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. When measuring, you may need to make clearance considerations for cabinets, built-in microwaves and range hoods that may be above your cooking space. The installation requirements for your specific cooktop model may vary and your product literature should be your primary source of information.
Cooktops that are installed in kitchen islands may require additional planning. Standard kitchen islands are about 24 inches deep; however, you’ll likely need a deeper island if you’re adding a cooktop. Islands with a cooktop should generally be about 36 to 42 inches deep.
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.
Beyond space requirements, you’ll want to consider the flow of your kitchen design and traffic.
Here are some additional clearances you will need to consider:
Step 1: Measure upper cabinet depth and height
If applicable, measure the size of the upper cabinets on either side of the cooktop, going from the bottom of the cabinet to the top of the cooktop. Double-check by measuring from the top of the cooktop to the bottom of the cabinet for the most accurate measurement.
Consider both cabinet depth and the distance from the cabinets to the countertop. Exact clearance measurements vary depending on the make and model of your cooktop, so you should always refer to your product manual for model-specific information. Typically, however, cooktops require 30 inches above and one- to two-foot clearances on each side.
You can verify that your space has the proper clearance for your new cooktop by measuring the width and depth of the appliance and subtracting ½ to one inch on each side. This helps include the overhanging lip on your countertop and makes sure there is plenty of room for the burners.
Step 2: Measure the height above the cooktop surface
Check minimum clearances needed from the cooking surface to the bottom of cabinets or other combustible surfaces.
Typically, you’ll need at least 30 inches of vertical clearance between the cooktop and materials above, such as cabinets. Measure from the cooktop to the bottom of your upper cabinets or other combustible surface. Then, repeat the process, measuring from the bottom of your cabinets or combustible surface to the top of your cooktop. Ensure that you have the same measurement on both before moving forward.
Required height measurements can also 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. Range hoods are typically installed 20-24 inches above electric cooktops and 24-30 inches above gas cooktops.
In general, there should be no more than 36 inches from the cooktop’s surface to the start of the range hood. Installing a range hood higher than 36 inches may decrease your range hood’s ventilation capabilities.
Step 3: Measure the distance between the cooktop and wall
The distance between the cooktop and any adjacent walls or other combustible materials may also require a minimum clearance. Measure the distance between the back edge of your cooktop and the wall to ensure it meets the minimum recommended clearance.
The distance between your cooktop and the back wall should be between three to 10 inches. This varies depending on the make and model of your appliance, so be sure to consult your owner’s manual for model-specific installation requirements.

How do cooktop sizes vary by fuel type?
Electric, gas and induction cooktops may vary by power source, but typically offer the same range of sizes. Standard cooktop sizes are generally between 30 and 36 inches and usually feature four or five burners. Explore the benefits of induction, gas and electric cooktops to find the best model for your kitchen.
Can you replace a cooktop with a different size?
It depends on your space. If you are moving from a larger cooktop to a smaller cooktop, you may be able to use a trim kit to fill in any gaps. If you are moving from a smaller cooktop to a larger cooktop, ensure that your counters and cabinets can accommodate the extra width.
You may need to remove some cabinets to accommodate the new size, depending on your measurements. Requirements vary by model, but cooktops will generally need 8 ½ to 12 ⅞ inches of clearance on each side.
Do all 30-inch cooktops have the same cutout size?
Cutout sizes may differ between models, even if they have the same appliance dimensions. The difference is usually no more than 1 ½ inches; however, it will affect how much space you need. It’s important to measure and know the dimensions of both the old and new appliance before purchasing.
What size cooktop do I need?
The size that you need depends on your cooking requirements and the amount of space in your kitchen. Standard cooktop sizes typically range from 30 to 36 inches wide. If you’re looking for an even larger size, commercial cooktops are typically 30 to 48 inches wide, and some models may offer larger sizes, as well as compact options that are closer to 15 inches.
