If your counter has a narrow gap and a standard microwave is too wide to slot in, this list is for you. A 15 inch wide microwave must fit your shelf gap while still delivering enough wattage to reheat leftovers quickly. Below are three countertop models that fit that middle ground, and each one solves the width-versus-wattage trade-off differently. Before you read on, one honest note: this list uses flexible, human-like matching for about 15 inch width, so it accepts units roughly 14 to 16 inches wide and rules out full-size 19 to 24 inch machines. Not every pick is the exact number you typed in — the nearest same-type size and wattage does the same job, and you deserve to know that up front.

Width gets it onto your counter, but interior capacity and wattage decide how well it reheats a dinner plate. That is the balance every pick below is judged on, and it is exactly what separates a good 15 inch wide microwave from one you regret squeezing onto the counter.
Our Picks at a Glance
How To Choose The Best 15 Inch Wide Microwave
Width is the starting point, but a narrow machine with low wattage will leave you waiting on a bowl of soup. Start with your available gap, then work backwards to wattage and interior volume. Those three numbers decide almost everything about daily satisfaction.
Measure The Gap, Not The Old Unit
The advertised width is the outside of the cabinet, and the box that ships it is wider still. Leave a little breathing room on each side, because a microwave pushed flush against a cabinet wall traps heat and stresses the vents. If you are replacing an older unit, do not assume the shelf is the same size you remember — measure the opening itself.
Wattage Decides Your Patience
Wattage is the raw heating output, and it sets how long a frozen dinner takes. A 1000-watt machine tackles leftovers and frozen dinners in the time you expect, while a 700-watt unit takes visibly longer on the same job. For a single person reheating coffee and snacks, the lower figure is workable; for a family warming full plates, the higher one saves real minutes every day.
Capacity In Cubic Feet, Explained Plainly
Interior size is quoted in cubic feet — a measure of how much open space you get inside the cavity. A 0.7 cubic-foot cavity holds a popcorn bag and a mug but tight on a dinner plate, while a 1.1 cubic-foot interior takes a standard plate with room for a cover. Match the cavity to the plates and dishes you heat most weeks, not the largest one you might cook once.
Controls And The Child Lock
Button panels with a digital display are the easiest to use accurately, while a mechanical knob looks charming but takes a moment to set an exact time. A child safety lock keeps little hands out — genuinely useful, though it can also frustrate adults who have to open up it every session. Consider who else uses the microwave before choosing a button panel or a child lock.

In‑Depth Reviews
1. Emerson MWR7020W Compact Countertop Microwave Oven
Our pick — over 4★ from 450+ verified ratings; the strongest balance of quality and price.
The narrow one that slots into cramped counters and looks like it belongs there.
This is the pick for the tiniest kitchen on your list. It measures roughly 13 inches across, so it slides into gaps where a standard microwave simply will not go — dorms, office kitchenettes, and studio apartments are exactly its audience. The retro white shell with a chromed handle and control button is the reason people stop and look at it, and the button panel keeps things simple: pick a power level, set the time, press start.
What it does inside is modest by design. The 0.7 cubic-foot cavity and 700 watts put it firmly in the light-duty bracket, which is fine for popcorn, snacks, and reheating a mug of coffee but visibly slower on a full dinner plate. Five power levels and 8 pre-programmed settings give you shortcuts for beverages, frozen vegetables, pizza, popcorn, and potatoes, and there is an express function plus defrost when you need to move quickly. A child safety lock and a removable glass turntable round out the practical side.
Owners describe a dial that runs in a set order — power, then time, then start — and the design earns genuine affection. A five-star owner wrote: “Wonderful microwave! It is great looking so perfect for my kitchen. Love the color and as far as function, it is great! Highly recommend it.” That said, heat distribution is the recurring split. Some report it heating food perfectly; others find it uneven and note the end-of-cycle beep is loud. The chrome buttons sit high and the door latch is tight when new, loosening with use. It is a lifestyle appliance first and a power cooker second.
Where it wins
- Compact footprint fits the smallest counter gaps
- 8 auto menus plus express and defrost for quick jobs
- Child safety lock and removable glass turntable included
Where it concedes
- 700 watts and 0.7 cu. ft. limit it to light reheating
- Heat distribution divides opinion — some find it uneven
- Dial-based time setting and a loud finish beep take adjusting to
Made for you if: you have a narrow shelf, rarely cook full meals, and want something that looks good sitting out.
Wrong fit if: you need to warm family-size plates quickly — the wattage will leave you waiting.
2. Farberware 1.1 Cu. Ft. Countertop Microwave Oven
Packs 1000 real watts into a 15.47-inch frame built for tighter kitchens.
This one solves the width problem from the opposite end: full 1000 watts inside a 15.47-inch frame. For an apartment or a one-to-two-person household, that is the combination that actually works day to day.
Ten power levels give you control that the smaller pick cannot match, and 8 auto-cook settings cover popcorn, pizza, potatoes, frozen and fresh vegetables, beverages, meat, and bread. There is an express cook function and a +30-second button for extending a run without resetting, plus auto defrost and a child safety lock. The interior measures 13 inches wide by 13.5 inches deep by 9 inches high, which one owner described as “slightly wider than standard dinner plate” — a genuinely useful detail if you plate real dinners.
Owners praise the 1.1 cubic-foot cavity most, and it earns that praise: a standard dinner plate fits with room to spare. The catch is the door. The latch draws the heaviest criticism for being stiff and the auto lock and open up cycle for being fussy, and a few units have been reported failing after months of light use. The 1000 watts also split opinion — some find it quick, some find it uneven. Pair the size with the capacity and it is a strong everyday machine; just treat the door gently and check the control-panel surface when it arrives, since some units show a scratched or bubbled coating.
Best single reason to buy: it hands you a full 1.1 cubic feet and 1000 watts without demanding a wide slot — set against the Emerson’s 0.7 cubic feet and 700 watts, that is a real step up in usable power per inch.
The honest trade-off: the door mechanism is the weak link, so if a light, easy-open latch matters more to you than capacity, size your expectations accordingly.
Reach for this if: you want a genuine dinner-plate interior and 1000 watts while staying inside a mid-width footprint.
Look elsewhere if: a fuss-free door and a rock-solid long-term record are your top priorities.
3. BLACK+DECKER Microwave Oven Countertop, 1.1 Cu.Ft, 1000W
A 14.8-inch stainless workhorse with a beautifully readable control panel.
At 14.8 inches wide this is the narrowest of the two 1000-watt machines here, and it pairs that with the quietest reputation of the group — the recurring praise is simply that you can barely hear it running. The dimensions run 20.6 by 14.8 by 11.8 inches, the cavity holds 1.1 cubic feet, and a removable 12.4-inch glass turntable gives you a wide, easy-to-clean surface for big plates.
The control panel is where it pulls ahead of the Farberware. Pre-programmed buttons cover popcorn, potato, pizza, frozen vegetable, beverage, and dinner plate, ten power settings give you fine control, and the large LED display with a child safety lock, interior light, and 30-second express cooking make short work of everyday reheating. It is the strongest everyday reheater of the three, and its stainless door frame lifts the look above its plasticky rivals.
The trade-off is the interior. Owners consistently note it is tight — a dinner plate plus a splatter cover just fits, with little spare room — and that cook times run on the long side for the wattage rating. One common complaint is that the child safety lock is awkward to switch off, which can trip up guests and older family members who are not used to it. An occasional unit fails early, so keep your paperwork handy inside the return window. Overall it is a sensible, quiet machine for someone who mostly reheats single servings.
What it nails: quiet running and a clear, intuitive button layout — the two things you notice every single day.
What nags: the tight cavity and the fiddly child lock are the small daily annoyances worth knowing before you buy.
Built for: the buyer who reheats single servings and prioritizes a quiet, good-looking, easy-to-read machine.
Second thoughts if: you regularly warm large platters — the snug interior will fight you.
Understanding the Specs
Wattage And Real Cook Time
Wattage is the microwave’s heating muscle. Higher wattage generally means shorter cook times for the same food, because the machine is pushing more energy into it. When you compare this list, the jump from 700 watts to 1000 watts is the difference between a quick reheat and a noticeable wait — worth weighing against how often you actually cook versus reheat.
Capacity In Cubic Feet
Cubic feet measures the open space inside the cavity, and it is the number that decides whether a full dinner plate, a casserole dish, or a popcorn bag fits comfortably. A 0.7 cubic-foot interior is snack-and-mug territory; a 1.1 cubic-foot cavity handles plates with room for a cover. Match capacity to the meals you cook most, not the rare big one.
Power Levels And Presets
Power levels let you fine-tune intensity — ten levels give you more precise control than five, which matters for defrosting and delicate reheating. Preset menus are one-touch short-cuts for popcorn, pizza, and potatoes. They are genuinely handy when they line up with how you cook, and quietly ignorable when they do not.
Physical Fit And Clearance
The quoted width is the outer cabinet, and the machine needs breathing room beside and behind it so heat can escape the vents. Measuring your gap before ordering is the single most important step here — a microwave that fits the width but blocks its own vents will run hot and age faster.

Final Thoughts: The Verdict
For most narrow-counter kitchens, the 15 inch wide microwave winner is the Farberware 1.1 Cu. Ft. because it packs the full 1.1 cubic feet and 1000 watts into a 15.47-inch body, giving you real dinner-plate capacity without a wide footprint. If you want the quietest, most intuitive everyday reheater with the clearest control panel, grab the BLACK+DECKER 1.1 Cu.Ft. And for the smallest space or a retro look that fits a 13-inch gap, the Emerson MWR7020W is the one to reach for — just know it is built for snacks and single servings rather than full family plates.
