What are the sizes of microwaves?

If you’re looking for a new microwave you can’t have failed to notice how many different sizes, types and variations there are out there these days.

What are the sizes of microwaves?


So what are the sizes of microwaves? In terms of capacity, microwaves can typically range from around 15 to 40 litres.

The capacity of a microwave refers to the total volume available within the cooking cavity. This is typically stated in litres (or in cubic feet). It’s important to remember that when you talk about the total capacity not all of it will be available for cooking.

This is especially true of the turntable style microwaves that have space taken up by the rotating table. This also applies to combination ovens that may have other fittings internally. However, the total capacity is still good indicator of available cooking space. Sometimes the actual available cooking capacity will be stated within a microwave’s instruction manual.

Below is a simple table that gives you an idea of roughly how many people each capacity of microwave could ideally cater for.

15 – 20 Litres1 – 4
