Cooktop Cutout Size
Standard Cooktop Cutout Size
Most built-in cooktops require a countertop opening that is approximately:
Width: 28.5 to 29.75 inches
Depth: 19 to 20 inches
Cooktop cutout dimensions vary slightly depending on the brand and model. Before purchasing a new cooktop, it is important to measure the countertop opening carefully.
Many homeowners discover installation problems after the cooktop is delivered because the countertop opening does not match the appliance dimensions.
To avoid this problem, verify the appliance measurements before purchasing.
Measure the width of the countertop opening from left to right.
Measure the depth of the opening from the back edge to the front edge.
Check that the countertop is flat and free of obstructions underneath.
Write the measurements using decimals (example: 29.25 inches).
The Appliance Fit Check app helps homeowners determine whether a cooktop will fit the available countertop cutout before purchasing.
The app compares appliance product dimensions with your countertop opening measurements and returns one of four results:
• Fits Perfectly
• Tight Fit
• Requires Modification
• Does Not Fit
This helps avoid cooktop installation surprises after appliance delivery.
