What Size Microwave Do I Need? Complete Guide

Like most people, you probably don’t know what size microwave oven you need. You might have an idea about what size microwave oven you want, but you don’t know how big your kitchen is or how much space there is to work with. If this sounds familiar, then you’re not alone. According to the National Kitchen and Bath Association (NKBA), the average U.S. household spends $2,200 annually on appliances and $1,400 on a new kitchen. That’s a lot of money to spend on something you might not even know how big it is!

 Why Is Microwave Oven Size Important?

Microwaves are a great way to cook food at home, but if you have a small kitchen, finding a microwave that has a larger capacity is an important decision. A microwave that has a large capacity allows you to cook more food at once without having to switch between appliances.

A microwave does not cook food evenly, and you could end up with a meal that is either overdone or underdone. When cooking for a large group of people, it is best to have enough food. That way, you don’t have to worry about whether they are eating enough or not. If you have too much food, some of it will likely get overcooked.

How are the Sizes of Microwaves Measured?

When we think of a microwave oven, we tend to think of its size. But what about the internal measurements? There are two types of internal measures that most microwaves have: volume and capacity.

Microwaves are expensive, and many people have had them for a long time, so there’s a good chance you already have a microwave. If not, you can buy a brand new one for less than $100.

How are the Sizes of Microwaves Measured?

Microwave ovens are used by millions of Americans every day. And while many people know that microwaves use very little energy, not everyone knows how big a microwave is.

Internal Dimensions

1. You can measure the internal dimensions of your microwave by following these steps:

2. Measure the interior length of your microwave (the length of the oven)

3. Multiply that length by the interior width of your microwave (the width of the oven)

4. Add the interior height of your microwave (the depth of the oven)

What are Standard Microwave Sizes?

A built-in microwave is an appliance integrated into the kitchen’s design. It is a convenient feature that makes cooking much more accessible.

This is the best microwave for the price because it has a large capacity, and it is straightforward to use. The only downside is that it does not have a turntable.

What Else to Consider?

The oven door will not seal well, and metal utensils will conduct electricity into the microwave, causing an electrical shock.

I have used a convection microwave for years, and I love it! I recommend it because it is not only a quick way to heat food but also cooks it evenly, which is excellent for the food I serve.

Microwaves have gotten smaller over the years, but they’re still bulky and don’t leave much counter space. The countertop microwave is a great way to save counter space while giving you enough cooking power to make a quick meal for one or two people.


When you buy a microwave, you will want to consider your needs first. How many people will you feed, how much food do you want to heat up, how large will the oven be, and how much space will you have on your counter? You will also want to check your budget. Depending on the size of your kitchen, you may be able to afford a larger, more expensive model. Plenty of microwaves out there will give you more than enough cooking power and will not eat up a ton of counter space.

I recommend that you read reviews about different microwaves before you buy one. They will be able to give you more information than you may need about the products themselves.
