How deep should a microwave cabinet be is one of the main concerns, while making a cabinet space for your oven?

Microwave Sizes:

How deep a microwave oven cabinet should depend on the size of your oven. A standard microwave is around 30″ wide, 17″ high, and 15″ to 18″ deep.

Moreover, the built-in ovens also fall in this standard measurement. You can get the exact dimension by looking at the cut-out dimensions and also product dimensions.

Furthermore, it is not measured for every microwave out there, you also have options of a smaller oven.

Here are some dimensions of both compact and standard microwave so that you get a better understanding –

Compact Size:

Compact ovens have a capacity of around 0.5 to 0.9 cubic feet and range from 15 inches to almost 19 inches.

The height usually is 10 to 11 inches and the depth starts from 12 inches to almost 16 inches while the door is closed. 

Standard Size :

Standard microwaves are bigger and have a capacity of 1.0 to 2.2 cubic feet. The width stands around 21 inches to 25 inches and the height typically is 12 to 15 inches.

Moreover, the depth while the door is closed is 16 to 20 inches.

A microwave cabinet accommodates your oven rather than having it on the countertop. It not only saves space but also compliments the looks of modern households.

The cabinet holds the oven over the top of your kitchen, out of sight but also in reach for usage.

These microwave cabinets are built into the top row of your kitchen cabinets which allows you to reach when necessary and also keeps the oven out of sight.

Installation Process Of Microwave Cabinet – Must Know

One thing you might face while installing the microwave in the cabinet is the depth. As standard ovens will stick out a little bit in a standard cabinet.

However, if you made it from scratch then there is no issue. The oven will sit flush inside the cabinet. 

Another issue is the holes that are used for attaching the microwave with the cabinet. In a standard cabinet, there is a problem as the oven will stick out and the holes will not match to set the appliance perfectly.

The holes are pre-drilled in most cases unless you custom-made the cabinet for your oven. 

If the holes do not align with the microwave then the installation is not possible.

The best option if you wish to have a built-in oven in your kitchen then get a smaller oven or make the cabinet according to the measurement of your appliance. 

Now coming to the doors of the cabinets. If the microwave is sticking out then is there going to be an issue while opening the oven’s door.

The microwave’s door opens from the left hand side and the cabinet door from the right-hand side.

So, there is no issue there; however, if the cabinet door opens towards the outside then you will not be able to open the oven’s door.  

Which Is Better, Countertop or Built-in Microwaves

It depends on the space and how you want your kitchen to look. First priority is the space, which is compulsory if you have a small kitchen.

In that case, a built-in microwave is the best option as it will be in the cabinet and consume less space on your countertop. Moreover, you will have more room to work within the kitchen. 

However, if space is not an issue, then a countertop microwave is the best option. As it will be in reach rather than reaching above your head to reheat or cook food in the oven.

Moreover, it is less risky to drop the plate while pulling it out of the oven. 

Advantages Of A Built-In Microwave

A clean kitchen is a beautiful sight for any home cook to see in their house. It does not only mean cleaning out the trash and the spilled food in the kitchen, it also means the look of the kitchen should also be clean.

That means no unnecessary things here and there nor any appliance someplace which kills the décor of the kitchen. 

That is where a built-in microwave comes to play, as not only looks stylish and compliments your entire kitchen but also frees up a lot of space.

You get full access to the countertop, which means more surfaces to work on. Moreover, it also provides good ventilation for the microwave. 

How To Measure The Dimensions Of A Built-in or Over The Range Microwave

Measurements are very important if you are trying to fit an oven or built-in microwave. Here is how you get those measures –

  • First remove the old or current microwave from the cabinet. It allows you to measure the dimensions inside the cutout.
  • Now grab a measuring tape and firstly measure the width inside the cutout.
  • After that you will get the numbers for the depth and also the height of the cutout. 


Now that we have got the measurements and installation process out of the way, it is time to ensure your safety. The cabinet should be 30 inches above the cooktop of an electric stove for safety.

On the other hand, if you use a gas stove then there is 36 inches of space between the bottom of the cabinet and the stove. 

Moreover, the bottom of the cabinet should be at least 66 to 72 inches from the floor, and from the countertop, it should be 18 inches.

It is for your safety and it also allows the most efficient usage of your cooktop.
