Standard Dishwasher Widths

Built-in dishwasher widths break into two groups: standard 24-inch models and compact or ADA 18-inch models. All five dishwashers in the current dataset are 24-inch-class units. Their chassis widths range from 23.5625 inches to 23.875 inches, deliberately narrower than the 24-inch cabinet opening to allow installation brackets and side clearance.

Within the 24-inch class, there is still variation. The Bosch SHPM88Z75N, Bosch SHE53C85N, and Bosch SHXM4AY52N share the narrowest chassis at 23.5625 inches. The Samsung DW80R5060US is 23.875 inches, and the LG LDTS5552S is 23.75 inches.

Compact and ADA dishwashers are typically 18 inches wide for smaller kitchens, though none are represented in this dataset. Their heights are usually similar to full-size models because they still install beneath a standard countertop. Depth is the dimension that varies most with tub design and door style.

Tub capacity, measured in place settings, is not directly tied to chassis width in this dataset; both the narrowest and the widest 24-inch models list 15 place settings. The published electrical ratings that are available all run on 120V, with amperage between 12A and 15A.

Capacity is measured in place settings. The dataset shows 15 to 16 place settings. Bosch’s 800 Series and 300 Series models list 16 place settings, while the 100 Series model and the Samsung and LG models list 15.
