Dishwasher Dimensions: 18-Inch vs 24-Inch
Nearly every built-in dishwasher is 24 inches wide (standard) or 18 inches (compact); height and depth barely change. Here are the dimensions, the rough-opening detail that trips people up, and every ENERGY STAR model we track at each width.
Standard 24-inch vs compact 18-inch
| 24″ (standard) | 18″ (compact) | |
|---|---|---|
| Opening width | 24″ | 18″ |
| Height | 33½–34½″ | 32½–34½″ |
| Depth | ~24″ | ~22–24″ |
| Place settings | 12–16 | 8–10 |
The “24-inch” refers to the cabinet opening — the unit itself is about 23½″. In older or custom kitchens that opening isn’t always a clean 24″, so measure before you order. The full method and the rough-opening gotchas are in dishwasher sizes: 18″ vs 24″.

Frequently asked
What is the standard dishwasher size?
24″ wide, about 34″ tall, and roughly 24″ deep — the size most kitchen cabinets are built around. It typically holds 12–16 place settings.
Will an 18-inch dishwasher fit a 24-inch opening?
It slides in, but leaves a 6″ gap that needs a filler panel or cabinet. Match the unit to the opening rather than forcing the swap.
What is the rough opening for a dishwasher?
For a standard unit, a 24″ wide × 34½″ high × 24″ deep cabinet opening. The appliance itself is slightly smaller so it can slide in.
