Question: are built in dishwashers a standard size?
Answer: Standard size is generally listed as 24 inches wide, 24 inches deep, and 35 inches high, with leveling feet that let you adjust the height to fit neatly under the counter. But the dishwasher itself may measure 23 5/8 by 23 5/8 by 34 inches—some wiggle room is required to get the unit into place and hook it up.
