The Best Compact Microwaves When Counter Space Is Precious
For small spaces, look for a countertop compact microwave with an exterior width under 19 inches and a capacity between 0.7 and 0.9 cubic feet, that size handles everyday reheating without eating your counter. Wattage between 700W and 1000W is enough for most small-space cooks, though higher wattage cuts reheat time noticeably. The Toshiba MM-EM07PA(BK) at 17.1 inches wide and the Frigidaire EMW788BLUARGENT at 18.9 inches wide are two of the narrowest countertop options with real buyer track records.
What 'Compact' Actually Means in Microwave Terms
Compact microwaves typically land between 0.5 and 1.1 cubic feet of interior capacity. That translates to an exterior width somewhere in the 15-to-22-inch range, which is a wide spread, so exterior dimensions matter more than the capacity number when you are shopping for a tight spot. A 0.7 cu ft microwave like the Frigidaire EMW788BLUARGENT measures 13.27 x 18.9 x 11.52 inches and weighs only 14.5 pounds, making it genuinely easy to tuck under a cabinet or move when needed. Compare that to a 1.6 cu ft model like the Magic Chef MCM1611W at 17.9 x 21.8 x 12.8 inches, similar product category, but a noticeably larger footprint.
Wattage and What It Means for Real Cooking
Wattage is the single most practical spec on a compact microwave. A 700W model like the Toshiba MM-EM07PA(BK) or the Frigidaire EMW788BLUARGENT will reheat leftovers and boil water just fine, it just takes a bit longer than a 1000W unit. If you frequently heat dense foods like casseroles or frozen entrees, a 1000W microwave (such as the Emerson MWRG0901W at 1000W) cuts down on uneven heating. At the high end, the Toshiba ML2-EC09SAIT(BS) delivers 1800W with convection heating, which is rare in a compact footprint and lets it double as a small convection oven. Match wattage to how you actually cook rather than chasing the highest number.
The Smallest Footprints Worth Buying
For genuinely tight spaces, a dorm room, RV galley, or a kitchen with almost no free counter, the Toshiba MM-EM07PA(BK) is one of the most space-efficient options available, measuring 12.2 x 17.1 x 9.5 inches with a 0.7 cu ft cavity and 700W output. Its 9.6-inch turntable fits standard dinner plates. The Frigidaire EMW788BLUARGENT is close behind at 13.27 x 18.9 x 11.52 inches with a dial control that is simple to operate in a cramped setup. Both run on standard 120-volt outlets, so no special wiring is needed.
When Convection Heating Is Worth the Extra Size
A compact microwave with convection heating circulates hot air around food the way a small oven does, letting you brown and crisp things that a standard microwave just steams. The Toshiba ML2-EC09SAIT(BS) pairs convection with 1800W of microwave power in a 17.6 x 19.5 x 11.5-inch package, compact enough for most kitchens, with a 10-power-level touchscreen and a 4.0-star rating across more than 2,100 reviews. At $259.99 it costs more than a basic compact, but if your small kitchen has no oven at all, the convection function can meaningfully expand what you can cook.
Installation: Countertop Is Your Only Real Option in Small Spaces
Over-the-range microwaves require cabinet installation and a dedicated circuit, not practical if you are renting or retrofitting a small kitchen. Every genuinely compact model worth recommending here runs on a standard 120-volt outlet and sits on the counter, so installation is simply: set it down, plug it in. Allow at least 3 inches of clearance on the sides and back for airflow. If you are stacking it on a shelf, verify the microwave's full height including any vent gap; most compact units are between 9.5 and 13 inches tall, which clears a standard 15-inch shelf with enough ventilation room.
Common mistakes to avoid
- Buying by interior capacity without checking the exterior width, two 0.9 cu ft microwaves can differ by several inches in overall size.
- Forgetting ventilation clearance, blocking the rear or side vents causes overheating and shortens the appliance's life.
- Choosing 700W thinking it is fine and then being frustrated with uneven heating on thick frozen meals, 1000W is the better minimum if you cook dense food regularly.
- Ignoring turntable diameter, a 9.6-inch turntable (like the Toshiba MM-EM07PA(BK)) will not fit a standard 10-inch dinner plate flat.
- Picking an over-the-range compact model when no cabinet or dedicated circuit is available, countertop is almost always the right choice for a small space.
- Not checking outlet placement before ordering, a short power cord on a compact microwave can force an awkward position on the counter.
Frequently asked questions
What size microwave fits in a small kitchen?
For most small kitchens, a 0.7 to 0.9 cubic foot microwave with an exterior width under 19 inches is the right target. That size fits standard mugs and most bowls while leaving meaningful counter space on either side. The Frigidaire EMW788BLUARGENT (18.9 inches wide) and the Toshiba MM-EM07PA(BK) (17.1 inches wide) are solid examples of that category.
Is 700 watts enough for a compact microwave?
700W is enough for reheating leftovers, softening butter, warming soups, and defrosting smaller portions. Where it falls short is cooking dense frozen foods, where lower wattage leads to hot spots and longer cook times. If you plan to cook frozen meals regularly, a 1000W model is a better fit without much size penalty.
Can a compact microwave replace an oven in a tiny kitchen?
A standard compact microwave cannot brown or roast the way an oven does. A convection microwave like the Toshiba ML2-EC09SAIT(BS) is the exception, its convection mode circulates hot air and can bake and brown small dishes. For a true oven replacement in a small space, look specifically for a compact model labeled as a microwave convection oven.
How much clearance does a compact microwave need?
Most manufacturers specify a minimum of 3 inches on the sides and back and at least 1 inch above the unit for ventilation. Check the manual for your specific model because some require more. Blocking the vents is the most common reason compact microwaves overheat and fail early.
Are compact microwaves harder to clean than full-size models?
The interior is smaller, so spills are closer to the walls and ceiling and can be easier to miss. A turntable lifts out for cleaning on most models, check that the turntable is removable before buying. Smooth interiors (common on touchscreen models) are easier to wipe down than interiors with textured corners.
