Standard Microwave Size
In choosing your next standard countertop microwave, there are two measurements you need to consider.
First is the external measurement; these dimensions will give you a general idea of how much countertop space your future microwave will cover. This measurement will also be helpful, especially if you’re looking for a microwave with a specific dimension to fit your available space.
The second measurement to consider is the internal space or how much your microwave can take in. This is measured in cubic feet.

What Size Microwave Do I Need?
You can have any microwave you want just as long as you have the counter space or the cabinet space for it. Luckily, there are varieties available to fit your needs, whether you are buying one for your apartment or you’re buying one to help with meal preparation for a big family.
A microwave is often selected based on the number of people in the household. For instance, if you will be using it to prepare food for 2 to 3 people a small microwave should do the trick (18 to 20 liters). Keep in mind that smaller microwaves often do not have the room for large dinner plates.
Larger families with 4 to 6 people will require a larger model (such as a 25- 30-liter unit.) Another consideration is wattage. Most microwaves have a wattage of 600 to 1200.
Select a larger wattage microwave if you will be cooking larger quantities of food at a time to cut down on cook times.
