How to Choose a Microwave
Average Cost of a Microwave
Countertop microwaves usually cost less than the other types. Small models start around $50, and midsized models are typically in the $100 to $300 range. OTR microwaves can be had for as little as $200, but most we test cost $400 and up. Models designed only to be built into cabinetry or a wall cost roughly $300 and up. Some countertop models are available with kits that give you a built-in look for less.
Space and Location
Think about where the microwave works best for you and about available space. Countertop models eat up countertop real estate. For example, midsized models are typically a little over 20 inches wide and up to 18 inches deep, and large microwaves can be an inch or two larger. You’ll want to factor in height as well, but unless you have very low cabinets, a countertop model should fit in nicely. Dimensions can be found on the model page for each microwave in our ratings.
Type
Countertop models are the most widely sold. OTR models are just that: They’re installed over the range. The built-in category includes models designed only to be built in—surrounded by cabinetry or built into the wall. Microwave drawers fall into this group and can be placed under the countertop or below a wall oven. And then there are some—but not all—countertop models that can be converted to built-ins with a kit.
Microwave Types
Depending on your kitchen, you can choose from countertop, OTR, and built-in microwaves. Note that the size of the unit doesn’t always translate to usable cooking space. Our research shows that usable capacity for tested microwaves is about 50 percent of what manufacturers claim. We measure the amount of space you can actually use. Models with more watts typically have more cooking power, but differences of 100 watts or so don’t matter much.
All the microwaves in our tests have a minimum of 700 watts; models with higher wattages provide faster and more even cooking. In our recommendations, for example, all microwaves feature power levels between 1,100 and 1,250 watts. Watts are listed in the full view of our microwave ratings; slide the Ratings & Specs bar to the right. The usable capacity and wattages presented below are based on our tested models, which represent the marketplace.
Countertop Microwaves
Price and easy installation are appealing. Just plug into an ordinary outlet—use one dedicated to the microwave, or it might trip the circuit breaker. Zero in on usable capacity in our ratings. Also note the microwave’s external dimensions, taking into consideration your available space. A stainless steel finish is common, and a convection feature is becoming available on more models.
Usable Capacity
Most of the tested models in this category have a usable capacity of about 50 to 60 percent of what manufacturers claim.
Watts
700 to 1,100 for small
800 to 1,250 for midsized
1,000 to 1,250 for large
Over-the-Range Microwave Ovens
Known as OTRs, these models free up counter space. But while they can be vented to the outside, don’t expect an OTR to vent as well as a range hood. Installation might require an electrician.
Usable Capacity
Most of our tested OTR models have usable capacity of about 40 to 50 percent of what manufacturers claim.
Watts
850 to 1,100
Built-In Microwaves
This category includes models designed only to be built in—surrounded by cabinetry or built into a wall. Microwave drawers, for example, can be placed under the countertop, removing them from sight lines, and glide out for easy access, or they can be installed below a wall oven. The look is sleek and integrated. Some countertop microwaves can be built in with a kit. Information below is for models designed to be built in, not for countertop models with optional built-in kits.
Usable Capacity
We haven’t yet tested enough built-ins to determine the percentage of usable capacity compared with manufacturers’ claims.
Watts
950 to 1,000
Features to Focus On
As the price goes up, so does the number of features. One we find invaluable is the sensor, which measures the steam that food emits and turns off the microwave when cooking is done. Here are other features to consider.
Turntables and Trays
They keep food moving for uniform heating. Most microwaves have a turntable that rotates food. Some instead have a rectangular tray that slides from side to side (which might work better for large casseroles or platters).
Quick Keys
A 1-minute or 30-second key requires just a tap to extend the preset cooking time, maintaining whichever power level was selected. It also allows quick adjustments to your previous settings—pushing the button more than once multiplies the time extension.
Racks
These let you speed things up, cooking multiple dishes simultaneously. They may also be used to improve convection cooking by allowing heat beneath the cooking dish. But you may have trouble fitting even a coffee mug in some models unless you remove the rack, so check when shopping.
Shortcut Keys
They take the guesswork out of cooking popular foods such as popcorn and frozen vegetables, and some models have shortcuts for oatmeal, pasta, stew, and grits.
Convection Cooking, Grilling, and Browning
These features offer the appeal of a second oven in your kitchen. But none of the tested models consistently provided the results you’d get from a regular oven or a grill.
Child Lock
If there are children in the house, a lockout function prevents children from opening the door and possibly getting burned by hot food.
Turntables and Trays
They keep food moving for uniform heating. Most microwaves have a turntable that rotates food. Some instead have a rectangular tray that slides from side to side (which might work better for large casseroles or platters).
