What are the dimensions of an over-the-range microwave?

Typical over-the-range microwave designs are 16 inches high by 30 inches wide by 15 inches deep. Internal capacities of over-the-range models range from 1 to 2 cubic feet.

Over-the-range microwave oven designs are often wider than typical countertop microwave models, which are typically anywhere from 18 to 24 inches wide. Wattages for over-the-range microwaves are similar to countertop models, ranging from 600 to 1200 watts. Internal capacities of these microwaves are also very similar to countertop models, despite the extra width of over-the-range microwaves. However, over-the-range microwaves often cost more than comparable countertop models, with prices as high as $1,000 for high-end ovens.
