Compiled by Radif Partners · How the figures are built
Standard dishwasher dimensions are set by the cabinet: almost every built-in model is made for an opening about 24 inches wide under a counter. On the ENERGY STAR list of November 12, 2026, 499 of the 595 certified dishwashers with plausible sizes sit in the 24 inch class and 77 in the 18 inch class, the narrow format for small kitchens; 19 have other widths. The median model is 23.70 in wide and 22.60 in deep, and holds 14 place settings. The list gives no height, which is set by the opening under a standard counter. An opening 24 inches wide and 24 deep takes 419 certified models; 176 are deeper than 24 inches. Energy use is close across the list: a median 239 kWh a year, $43 at the U.S. average price of August 2026. 118 rows whose sizes were entered in another unit are left out.
Dishwasher dimensions by width class
The list publishes the width and depth of each certified dishwasher, its capacity in place settings and its yearly energy. The table groups them by the two standard widths.
| Class | Models | Typical width | Typical depth | Typical place settings | Typical kWh a year |
|---|---|---|---|---|---|
| 24 inch | 499 | 23.80 in | 23.70 in | 15 | 240 |
| 18 inch | 77 | 17.60 in | 22.50 in | 8 | 234 |
Height: what the list leaves out
The ENERGY STAR dishwasher list publishes no height. Built-in dishwashers are designed for the space under a counter and have leveling feet to adjust; the model sheet gives the range of heights it accepts. Measure from the floor to the underside of the counter, at the front and at the back, and compare with that range. A new floor laid over the old one raises the floor and can close the gap.

Measuring the opening
Width: between the cabinet sides at the narrowest point. Depth: from the wall to the front of the cabinets, not the counter edge, so the door lines up with the cabinet doors. Then check what is behind: the water supply, the drain and the power, which often run through a cabinet next to the dishwasher. If the dishwasher sits next to a corner or a range, check that its door opens without hitting a handle.
Energy across sizes
Certified dishwashers use similar amounts of energy whatever their size, because the federal test sets the yearly figure for a fixed number of cycles (215 or 184 a year depending on the test version, 10 CFR 430). At the U.S. average price the median model costs $43 a year to run. The detail is on the dishwasher electricity page, and each width has its page: 24 inch and 18 inch.
