1. Kitchen Size and Layout

The first step in selecting a microwave is understanding which model and style will best fit your kitchen’s layout. Some microwaves fit best in kitchens with ample counter space, while others fit in homes with cabinets to spare for built-in or over-the-range models.

2. Microwave Types 

There are three general microwave types: built-in, countertop and microwave hood combinations. Discover the differences between these types of microwaves and their benefits to help you choose a microwave that’s right for the unique way you create.

Should I Choose a Built-in Microwave?

Built-in microwaves can either be installed directly into your cabinets or into a fixed wall to give your kitchen a sleek and integrated look. In some built-in models, the microwave doors open from the front like an oven, rather than swinging open like a traditional microwave. Some KitchenAid® built-in microwaves are designed to function like a kitchen drawer, where the microwave cavity opens like a drawer and food is placed inside from above. This option typically ranges between 24–30 inches in width and 17–22 inches in height, with a depth between 30–35 inches including the opened door. Built-ins typically have a wattage of 950-1,100 watts, offering a higher powered performance.

Other benefits of built-in microwaves include: 

  • Enhanced kitchen aesthetics

  • Flush with cabinets and other appliances

  • Free up countertops for more prep and cooking space

  • Can be installed at a lower height for more accessibility

If a built-in microwave sounds like it might be the perfect fit for your kitchen, discover the best built-in model for you with the KitchenAid® Built-In Microwave Buying Guide.

Should I Choose an Over-the-Range Microwave?

Over-the-range microwaves, or microwave hood combinations, are similar to built-in microwaves as they remove the appliance from your countertop and into the cabinets. The main difference is that over-the-range microwaves are typically installed above a stovetop because they double as a vent hood to clear smoke and odor from the kitchen when you cook. These models are typically about 30 inches in width, 17 inches in height and have an open-door depth of 42–45 inches. To ensure you have the right sized model for your cooktop, learn how to match your hood to your stovetop.

More reasons to consider an over-the-range microwave include:

  • Frees up counter space

  • Centralizes cooking tasks to one area of kitchen

  • Doubles as a vent hood

  • Modern and integrated design

Should I Choose a Countertop Microwave?

Countertop microwaves provide quick access to your appliance right on your kitchen’s prep station. KitchenAid® countertop microwaves come in multiple sizes to best fit your counters and a variety of styles and finishes to match the flow of your kitchen’s style. Countertop models range from 21–24 inches in width and about 13 inches in height, with an open-door depth ranging between 27–39 inches.

Other benefits of countertop microwaves include:

  • Can be placed anywhere within reach of a grounded outlet

  • Portability is great for renters 

  • Easy installation

  • Classic and timeless design

3. Microwave Sizes

When you’re shopping for a new microwave, there are two microwave measurements to consider: the external dimensions and the internal dimensions. Understanding your microwave’s external dimensions can help you find an appliance that will fit in the size and layout of your kitchen, while the interior dimensions help you understand the cooking space the microwave provides. KitchenAid® microwaves have a range of model sizes to best fit your kitchen, including low-profile microwaves that can fit above your stove in the space of an existing vent hood.

4. Features to Consider When Choosing a Microwave

Once you’ve decided which microwave size and type you need, consider which microwave features will benefit the way you create.


Microwaves with more wattage may cook your food more quickly. Typically, microwave wattage ranges from 900–1,200 watts. Most microwave recipes call for 1,000 watts of power for the best results, so you may want to consider a microwave model with high wattage when shopping.

Microwave Finish and Design

The design of your microwave can complement your style and decor, because your kitchen is more than just a prep and cook station. Whether your home has a contemporary or eclectic motif, KitchenAid brand offers microwaves with finishes like stainless steel and black stainless steel to fit your personal aesthetic. You can also protect your appliances from fingerprints and smudges with PrintShieldstainless steel finish.

Convection Cooking and Broiler Element

You can unlock new culinary possibilities and use your microwave as a second oven, with some models including features like convection cooking and the broiler element. Convection cooking settings on select KitchenAid® microwaves circulates heat around the cavity to reach baking temperatures above 400° F, while the broiler element combines high power and even coverage needed to achieve results similar to a grill.

Steam Cooking

KitchenAid offers microwaves with Sensor Steam/Simmer Cooking in select models that precisely steam food when you add water to the steaming container. 


Sensor Functions

Some microwave models can automatically adjust the time needed to reheat and cook your food using sensors so you can take the guesswork out of your making. Learn more about microwave settings and features.

Turntables and Trays

The turntable or tray inside a microwave keeps food moving for an even heat. Most models have a turntable that rotates food in a circle, but some have trays that move side to side to heat large and dense dishes.
