Microwave sizes

What are the standard microwave sizes?

Microwaves dimensions vary in width, heights, depth and capacity. There are no strict standards and actual measurements depend on a type of microwave. Every kitchen appliances manufacturer offer its own specifications for a particular product and microwaves will range in sizes from small compact with 0.4 – 0.5 cu. ft. (11.5 – 14.2 liters) capacity to a few times bigger dimensions.

Four parameters were analyzed: microwave width, height, depth and interior space or capacity. First line for each type of microwave is imperial measurements. Standard dimensions of a microwave in inches and capacity in cubic feet. Second line is sizes in metric system. Microwave dimensions in centimeters and capacity in liters.

Actual numbers might vary with up to 1/16” accuracy. While exact specification not that important for countertop microwaves, over the range, build-in or microwave drawers typically made according to standard kitchen cabinets sizes. But even following standard dimensions actual measurements will depend on kitchen appliances manufacturer. Typical over the range microwave under 30” kitchen cabinet might have an actual width 29 1/2”, 29 3/4”, 29 7/8”, 29 15/16” or precise 30”.

Typical dimensions over the counter microwave 24” x 14” x 16” (width/height/depth) and 1.5 cubic feet capacity.

Before ordering custom kitchen cabinets it is better to buy or at least know particular build-in microwave specifications and require opening.

What is a size of smallest microwave

Typically all microwaves which are less than 18 inches wide and 10 inches high refer as compact sizes. 17”W x 13”D x 10”H one of the smallest size of countertop microwave.

Biggest microwave dimensions

Large microwaves usually 30” or wider. 35 7/8”W x 18 5/8”D x 18 1/8”H with 2 cu. ft. capacity over the range microwave one of the biggest options available.

How heavy the microwave is

The weight of a new microwave depends on its dimensions. Compact up to 1 cubic feet capacity (29.3 liters) typically will be in a range between 32 – 39 pounds or 14.5 – 17.7 kilograms. Wider and higher products might be a few times heavier and 30” build-in microwaves might weight up to 100 lb (45.4 kg.) or even more.
