Step 1: Find the right microwave size

When it comes to kitchen appliances, microwaves can vary distinctly when it comes to size, shape and installation options. Before you buy a new microwave, consider what size is the best fit for your home.


A small Whirlpool® Microwave A standard Whirlpool® Microwave A large Whirlpool® Microwave
Microwave Size Small Standard Large
Microwave Capacity 0.5 cu. ft. - 0.9 cu. ft. 1.0 cu. ft. - 1.6 cu. ft. 1.7 cu. ft. - 2.2+ cu. ft.
Family Size 1-2 2-4 4+
Typical Use Day-to-day essentials like reheating single-serving meals and ingredient prep Reheating dinner plates and cooking medium sized dishes for family meals Defrosting, cooking or reheating large dishes or multiple dishes at once

Microwave dimensions

Microwave dimensions measure a microwave’s height, width and depth, helping you determine if your space can accommodate the appliance you have in mind. Some configurations—like small countertop microwaves—require as little as 10–11 inches of height, 15–18 inches of width and 12–16 inches of depth. Larger models are usually found in over-the-range and built-in configurations, measuring anywhere from 10–22 inches high, 24–30 inches wide and 12-¾"–25 inches deep.

Family size

In addition to the size of your kitchen, you may also want to take the size of your family into account. Unlike built-in or over-the-range models, some countertop microwaves won’t accommodate casserole dishes, platters and other larger serveware. On average, microwaves range in capacity from 0.7 cu. ft., which is suitable for most dinner plates, to 2.2 cu. ft., which is a better size for bigger cookware. It's important to consider what capacity you need to fit your dishes and suit your cooking needs.

Typical use

Before you decide on a microwave, think about how you typically use it. If you have a larger family or frequently entertain, you may want to invest in a larger microwave that lets you defrost, cook and reheat larger dishes.

Selection tip: Wattage is another important factor when choosing a microwave to fit your family's needs. Wattage indicates cooking power, with most models ranging from 500-1200 watts. The higher the wattage the more quickly it cooks foods. Most microwaves also offer a defrost setting that lowers the power between 20 and 30 percent. Learn more about safely defrosting foods in the microwave.

Countertop microwaves

These microwaves are easy to move and install. Simply place them on your counter and plug them into a regular wall outlet. Some countertop microwaves—like select Whirlpool® Microwaves—even come with trim kits that allow them to be converted into built-in models. Countertop microwaves can be an economical choice, and they come in a variety of sizes.

Over-the-range microwaves

These microwaves combine two appliances into one by replacing your stove’s range hood, making them a great microwave option for freeing up counter space. These microwaves can come with convenient features, like sensor cooking on select Whirlpool® Over-the-Range Microwaves, that make reheating even easier. Featured in this category are low profile microwaves, like these models from Whirlpool brand, which have a sleek design, roomy interior, and provide more space above your cooktop.

Built-in microwaves

Built-in microwaves, like wall ovens, are usually installed in a wall or among cabinets. Available in a range of sizes and power levels, built-in microwaves like these ones from Whirlpool brand are an excellent way to save space on your countertop. However, they do require professional installation—something important to consider when you’re buying a microwave.

Consider your layout when buying a microwave

Your kitchen’s layout is also an important factor. Countertop microwaves may work for more spacious kitchens, while an over-the-range or built-in model may help maximize space in more compact areas. Over-the-range microwaves also feature fans and vents to help clear the air around your cooktop.

Once you’ve decided on a kitchen microwave style that matches your layout, take some time to decide which features you need, such as pre-programmed settings, convection options or smart technology. Learn more about convection microwave cooking.

Convection microwaves use an extra heating element and fan that help you bake or roast foods right in the microwave. If you often find yourself short on oven space, microwaves with convection cooking can make it easier to crisp or brown multiple dishes at once.
