It may seem indifferent to find out typical measurements of everything in your home. In some cases, it may be. But when you lack space or want to scale correctly, it is important to find the correct sizes of microwave dimensions.

Microwave dimensions

Today we need to find out the sizes of different types of microwaves because in today’s world almost every home has one. Those without houses even use microwaves.

They have microwaves when they do not even have a kitchenette. Or even offices with nothing but microwaves and water tanks. So yes, microwaves are everywhere, which gives us a good reason to learn more about them.

The history of the microwave

Small stainless steel microwave

You will be amazed at how many people do not know where microwaves come from, especially those who have had a microwave oven all their lives. Would teens today believe microwaves were once a hotbed of conspiracies?

It all began at the end of the 2nd World War when the term microwave oven was used for military radars and not something used to make our dinner. At the time, companies building these radars were always studying new ways to use these waves.

They knew well that the waves could be used as a heat source, but this was primarily used in the medical field. Although knowledge was there and the idea was shared at the 1933 World’s Fair in Chicago, the actual application was not.

The release of the first microwave

It was not until 1958 that the application was shared with the world via Reader’s Digest. It shared that in 1947 a patent application was filed by Raytheon’s Percy Spencer to patent the use of microwaves.

You would not think that popcorn was a major focus then as it is now. One of the only foods still produced primarily through the microwave in private homes. But how was this discovery made? It all started with peanuts.

The man responsible for the discovery used the microwaves when he found that the peanut bar in his pocket was starting to heat up. His first introductory meal prepared with the waves? An egg! Not the best choice we now know.

As cheap as microwaves are now, in the 1950s, when the first microwave oven was released, the Tappan RL-1 was a wall-mounted microwave that cost almost $ 1300. In today’s world, it is almost $ 15,000.

The effect of radiation

In the 1970s, concern began to skyrocket that the radiation from microwaves was causing serious health problems. Unfortunately, in 1973, they confirmed that they could not control the safety of the microwaves.

The reason for this statement was that they did not have the technology to test the radiation. Most, however, assumed that this meant that they found out that microwaves were actually dangerous, which is not surprising.

Today, technology is advanced, which has given us safer microwaves and better testing to ensure that the microwaves we have are safe for cooking and for being nearby in general. But it is really the mindset of the everyday consumer that has changed the most.

Why do people use microwaves?

Many people just assume that those who choose a microwave over another food heater are lazy or young. But that is not true. After all, most homes in America have microwaves that are used regularly.

This is because some foods are simply better than microwaves. Other times, you can spend a tenth of the time cooking something that would take much longer to cook in the oven. Such is the microwave.

So microwaves are actually for convenience and specialty items. They are becoming more and more popular, even after all this due to the fact that they are the cheapest way to heat food, as well as the most convenient.

But did you know that there are many different sizes of microwaves? Yup. There may be a standard, but there are also different types of microwaves that you can buy. So it is crucial to find the right one for you.

What are typical microwave dimensions?

Microwave Dimensions: What you need to know

Microwaves are actually available in many sizes. They are usually sold anywhere from 1.0 cubic feet up to about 2.2 cubic feet capacity. In terms of width, you will find that most microwaves are between 21 and 25 inches.

The height is a little more standard with a small range from 12 to 15 inches for most microwaves. Although there will always be exceptions. These are just the typical intervals, not that your microwave should fit in this area.

There is also a possibility that the microwave you are eyeing is unique. Companies are always trying to find the next big thing, and sometimes it’s a weird microwave with features never seen before.

Note: there are still other sizes of microwaves not listed below, but these are few and far between. Almost every microwave oven you find in stores fits into one of the categories below.


  • Height: 12 ″ – 15 ″
  • Width: 21 ″ – 25 ″
  • Depth: 16 ″ – 20 ″
  • Capacity: 1.0 cu. ft. – 2.2 cu. ft.

The tabletop microwave is the standard microwave and probably the type of microwave you get. Most tabletop microwaves should have a clear path for ventilation as they are designed to be free-standing.

Many people like to use a kitchen cart for their microwaves. This makes it easy to move the microwave around and keep it away from the counter. If you are laying it on the countertop, consider putting a mat or refractory contact paper under it.


  • Height: 10 ″ to 17 ″
  • Width: 24 ″ to 30 ″
  • Depth: 15 ″ – 18 ″
  • Capacity: 0.8 cu. ft. – 2.1 cu. ft.

Over-the-range microwaves are made to go in a slot above the stove. They are made differently as they will be able to withstand the heat from the stove that runs upstairs as well as the lack of ventilation.

Although for the added safety boost you can always have the microwave outside, it is not necessary. You can simply have a small area for the microwave to ventilate back to the kitchen, although this will add heat to the room.

Microwave built in appliance


  • Height: 17 ″ – 22 ″
  • Width: 24 ″, 27 ″ or 30 ″
  • Depth: 20 ″ – 25 ″
  • Capacity: 1.0 cu. ft. – 2.2 cu. ft.

Built-in microwaves are usually slightly larger than other types of microwaves. This is because they are built into the room and often have a frame of some kind. They take up more space in some ways and less space in other ways.

Built-in microwaves are considered high-end and they look amazing. If you do not want to take up space on the site and have closet space left over, this is definitely your best option that will add value as well.


  • Height: 8 ″ to 17 ″
  • Width: 24 ″ – 30 ″
  • Depth: 15 ″ – 18 ″
  • Capacity: 1.0 cu. ft. – 2 cu. ft.

A drawer microwave can vary greatly because it can be turned into a drawer and adapted to different sizes of drawers. More often than not, they are actually smaller than your standard microwave, but not much.

They can also either be made to fit in a drawer and be used as a standard microwave or to become a drawer and slide out when it’s time to use. This is a very interesting type of microwave that saves a good amount of space.

  • Width: 21 ″ – 28 ″
  • Depth: 16 ″ – 24 ″
  • Capacity: 0.8 cu. ft. – 2.1 cu. ft.

A convection microwave oven is a multifunctional microwave oven that can function as a normal microwave oven and it can function as a convection oven. Now, this is the ultimate way to save space if you need to have both anyway.

The more time passes, the more options will also be added. Soon enough, there will be microwave ovens that serve as fryers, toaster ovens, and more. It is an exciting future for this device.


  • Height: 10 ″ – 11 ″
  • Width: 15 ″ – 18 ″
  • Depth: 12 ″ – 16 ″
  • Capacity: 0.5 cu. ft. – 0.9 cu. ft.

A mini-microwave can be used in any house, but it is designed to be used in motorhomes, small houses, and studio apartments. It is much smaller than a standard microwave but can work just as well as any other.

It will have a smaller capacity and will not be able to heat everything another microwave oven can. However, most TV dinners and other microwave items will fit. But for family meals, stick to a standard microwave.

What You Need To Know

Find the right microwave dimensions

Now that you know your options, you can start measuring. Start by deciding where you want your microwave. Most people prefer to put it on the countertop or over the range. Then measure the place you want to place it.

Since there are intervals for each type of microwave oven, it is important to know how large the free space will be. So take the tape measure and get started. If you find that the standard will be too large, switch to a small one.

Size is not important unless you plan to use the microwave regularly and feed your entire family with it for dinner. Otherwise, you can stick to a standard frying pan, pizza oven, or convection oven.
