Standard Dishwasher Opening Size
Most built-in dishwashers require a cabinet opening that is approximately:
Width: 24 inches
Height: 34 to 36 inches
Depth: 24 inches
Before purchasing a dishwasher, 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 space does not match the dishwasher dimensions.
To avoid this problem, verify the appliance measurements before purchasing.
How to Measure a Dishwasher Opening
Measure the width between the cabinets.
Measure the height from the floor to the underside of the countertop.
Measure the depth from the back wall to the front edge of the cabinet opening.
Write the measurements down using decimals (example: 24.25 inches).
The Appliance Fit Check app helps homeowners determine whether a dishwasher will fit the available cabinet opening before purchasing.
