The dimensions for kitchen appliances vary based on the manufacturer's specifications. However, appliances like ranges and dishwashers are often designed based on the standard counter depth of 24 inches and the standard counter height of 36 inches.
Appliances designed to fit in counter or cabinet space must conform to those dimensions. For example, a built-in microwave oven cannot exceed the space allotted for that appliance. When purchasing new appliances, homeowners should measure the existing space to ensure the product will fit.
Refrigerators range from 18 to 75 inches in height. The smallest refrigerators, which are compact refrigerators or "mini fridges," are often designed for small spaces or to fit underneath a counter. The dimensions of full-size refrigerators depend on their design.
For example, side-by-side refrigerators can measure up to 37 inches in width, 72 inches in height and 33 inches in depth. They feature a full-height refrigeration compartment on one side and a freezer compartment on the other. A top-freezer refrigerator, on the other hand, is up to 68 inches tall and 36 inches in width. It has a refrigerator on the bottom and a shorter freezer on the top.
Microwave ovens are often purchased for capacity rather than dimensions. Since microwaves often sit on countertops or kitchen islands, their dimensions are less important. The capacity of a microwave is measured in cubic feet, ranching from .4 to 2.1 cubic feet.
