Buying Guide for the Best Countertop Microwaves
Choosing a countertop microwave may seem simple, but a little research goes a long way toward making sure you pick a model that truly fits your lifestyle and kitchen needs. Consider how you plan to use your microwave: are you mainly reheating leftovers, cooking full meals, or defrosting ingredients? Also think about your available counter space and the size of dishes you usually use. By matching your habits with the right features, you can make everyday life a bit more convenient and efficient.CapacityCapacity refers to the internal space of the microwave and is usually measured in cubic feet. It determines how much food you can fit inside at one time. Small capacities (about 0.7–1.0 cu ft) are great for light use, single servings, or tight spaces, while medium capacities (1.1–1.5 cu ft) work well for most families and standard dinner plates. Larger capacities (1.6 cu ft and above) allow you to cook or reheat bigger dishes, like casseroles or large bowls. Choose a size that fits the types of dishes you commonly use and the quantity of food you expect to prepare.
WattageWattage measures how powerful a microwave is; higher wattage means faster and more even cooking. Entry-level microwaves typically offer 600–800 watts, which is acceptable for basic reheating, but may cook unevenly or take longer for more demanding tasks. Mid-range options (900–1100 watts) deliver better performance for most households, providing a good balance of speed and cooking results. High-end models with 1200 watts or more are best for those who cook or heat larger meals frequently. If you rely on your microwave for more than just reheating beverages, look for a wattage of at least 900.
Turntable SizeThe turntable is the rotating glass plate inside the microwave, and its size determines the maximum width of dish you can use. Smaller turntables (up to 10 inches in diameter) limit you to compact plates or bowls, while medium (11–13 inches) and large (14 inches or more) turntables provide more flexibility for bigger plates and casserole dishes. If you often microwave larger dishes or want the option to do so, check the turntable size to make sure your cookware fits comfortably.
Auto-Cook PresetsAuto-cook presets are pre-programmed settings that automatically set cooking times and power levels for common foods like popcorn, pizza, or vegetables. This feature makes using the microwave convenient and minimizes guesswork, which can be helpful if you aren't confident about cooking times. Entry-level models may have just a few presets, while more advanced microwaves offer a wider variety. Think about which foods you commonly heat or prepare in the microwave—if you often use shortcuts, more presets can save time and improve results.
Defrost FunctionThe defrost function allows you to thaw frozen food safely and quickly, without cooking the edges. Some microwaves offer only a basic time-based defrost, while others use weight-based settings to adjust defrosting automatically. If you regularly thaw frozen meat, fish, or prepared meals, a microwave with advanced or sensor-driven defrost options can be a real time-saver and help maintain food quality.
External DimensionsThe external dimensions refer to the microwave’s overall size, which is especially important if you have limited counter space. Microwaves are generally grouped into compact, mid-size, and full-size categories. Always measure your available space before buying, including height if you plan to place items on top. Choose a size that fits comfortably into your kitchen layout without crowding your counter.
Ease of CleaningHow easy a microwave is to clean can greatly affect your satisfaction over time. Features like removable turntables, smooth interior surfaces, and easy-to-wipe control panels make the process less of a chore. If you’re prone to food spills or want to minimize maintenance, look for models with nonstick interiors or steam-cleaning features.
