Dimensions of dishwashers are determined by the opening size they’re made to fit, rather than the measurements of the dishwasher. A dishwasher labeled as 24 inches wide might actually be more like 23-1/2 inches wide.
Standard built-in
Most cabinet openings are made to fit a standard dishwasher size.
Oversized built-in
Oversized dishwashers are built wider than the standard opening.
Small space or compact built-in
Designed for apartments, space-conscious homes and entertainment spaces, small space dishwashers have a slimmer width than standard dishwashers.
Portable, in-sink and countertop
Portable, in-sink and countertop dishwashers should not require an opening in your cabinetry, but you’ll still need to measure where they’ll go.
