Most built-in wall ovens require a cabinet opening that is approximately:
Width: 28.5 to 30 inches
Height: 27.5 to 29 inches
Depth: 23 to 24 inches
Before purchasing a wall oven, it is important to measure the cabinet opening carefully. Even small differences in height, width, or depth can prevent the appliance from fitting properly.
Many homeowners discover installation problems after the appliance is delivered because the available cabinet space does not match the wall oven dimensions.
To avoid this problem, verify the appliance measurements before purchasing.
Standard Wall Oven Cutout Size
Measure the width of the cabinet opening between the side panels.
Measure the height from the bottom support shelf to the top of the cabinet opening.
Measure the depth from the back wall to the front edge of the cabinet.
Write the measurements using decimals (example: 28.75 inches).
The Appliance Fit Check app helps homeowners determine whether a wall oven will fit the available cabinet opening before purchasing.
The app compares appliance product dimensions with your cabinet opening measurements and returns one of four results:
• Fits Perfectly
• Tight Fit
• Requires Modification
• Does Not Fit
This helps avoid wall oven installation surprises after appliance delivery.
