When your counter is tight but you still need to heat a full dinner plate, you are choosing between footprint and capacity. A 12-inch microwave—usually a 0.7 cu ft model that sits around 12–13 inches deep—fits dorms, offices, and small kitchens where every inch matters. You can still get power, presets, and a child lock in a compact unit, and this guide names the six best options for your money.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Before the list, one note: this roundup uses flexible matching for the search, so a few picks measure slightly wider or deeper than the exact number, with the nearest same-size 700W model serving the same purpose. If you want a 12 inch microwave for a dorm, a rental, or a tiny apartment, this guide pairs the right footprint with the right features for your space.
Our Picks at a Glance
How To Choose The Best 12 Inch Microwave
Buying a compact microwave depends on three numbers: the depth (so it fits your counter), the wattage (so it actually heats), and the capacity (so your plate fits inside). Most 12-inch models land around 0.7 cubic feet and 700 watts—enough for a standard dinner plate and fast reheating without hogging your whole counter.
Measure your space before you measure the microwave
The “12-inch” label usually refers to depth, and the actual unit may be a bit deeper once you account for the handle and rear vent clearance. Always check the Item Dimensions (D x W x H) rather than trusting the size name—a 12.93-inch deep model needs about 14 inches of clear counter space.
Match wattage to your cooking habits
Most compact microwaves run at 700 watts, which heats leftovers and drinks fine but takes longer than a 1000W+ full-size unit. If you mainly reheat coffee and frozen meals, 700W is plenty; if you cook raw food regularly, consider whether you will accept the slower cook times.
Look for the safety and convenience details
Child locks are common on these models, but they do not all work the same way—some need a button combo, others a handle pull. Presets for popcorn, potato, and beverages save guesswork, and an express cook button or +30 seconds shortcut cuts down the fiddling on busy mornings.

In-Depth Reviews
1. BLACK+DECKER Countertop Microwave Oven 0.7 Cu Ft
Our pick — over 4★ from 150+ verified ratings; the strongest balance of quality and price.
The compact counter champion that wins owners over with genuinely fast, even heating.
Owners talk most about performance, and it shows in daily use: this 700W oven with 10 cooking power levels reheats lunch and late-night snacks without the wait, and the preset row for popcorn, potato, pizza, frozen vegetables, beverages, and dinner-plate reheat covers almost every default task. The fingerprint-resistant black finish keeps things looking clean, and the multi-stage cooking function lets you go from defrost to reheat without hovering over the keypad.
The footprint stays dorm-friendly at 17.1 x 12.3 x 9.5 inches, and the 0.7 cu ft cavity still swallows a standard dinner plate. The crowd favorite—4.4 stars across 180+ owners—calls out the easy child lock and the rotating glass plate for even coverage. Buyers report “Love it; upgraded from 700W/0.7cu.ft.,” which says a lot about how this unit wears over time.
Compared to the Chefman below, this one is noticeably shorter at 9.5 inches high versus 9.53, and shallower at 12.3 inches versus 12.93, so it squeezes into tighter cabinets. The one honest trade-off is the door lock itself: it takes a beat to get used to, and a tall item like a large turkey is out of the question at this height.
compact power price
- Fast, even heating is the top praise—47 owners lead with performance
- Value for money ranks second, with 20 owners calling it a great price
- Quiet enough for a dorm room, per the noise feedback
small interior size
- Door lock takes getting used to—some find it awkward at first
- 9.5-inch height rules out roasting a large turkey
budget pick: you want the best-balanced compact microwave for a dorm or office, with presets and child lock baked in.
tight quarters: the interior height is modest—stick to dinner plates and bowls, not big birds.
2. Chefman Compact Countertop Microwave, 0.7 Cu Ft, Stainless
A stainless-steel stunner that stays silent when you need it most.
The Sound Button silences end-of-cycle beeps, a lifesaver for nurseries and shared offices. Beyond the silence, the 700W digital oven gives you 10 power levels from butter-melting low to rapid high, plus popcorn, beverage, and leftover presets and a +30 seconds button for quick top-ups.
The stainless body and white interior draw compliments on looks, and owners note the footprint is a real space-saver—the 12.93-inch depth makes it the deepest of the compact trio here, but the white interior visually opens it up. It holds a 10-inch dinner plate comfortably, and owners mention it has enough weight that it does not slide when you pull the door open. Customers note “700 watts, takes a little longer but the trade-off is it’s compactness.”
That quote captures the honest catch: at 700W, heating runs closer to a minute than 30 seconds, so it is not for the impatient. The child lock is also handle-based—you pull upward on the top edge to open—which owners find easy once they know the trick. A few owners note the unit runs a bit smaller than expected inside, so oversized bowls can be snug.
stainless style value
- Performance leads with 64 positive mentions—even heating is the norm
- Functionality follows at 50, with owners praising the intuitive controls
- White interior makes the small cavity feel bigger and cleaner
basic feature set
- Noise level is mixed—27 owners are split on how loud it runs
- Some find it smaller than expected inside despite the outer size
style choice: a stylish stainless unit with a genuine mute option for nurseries and shared offices.
bare bones: 700W means slightly slower heating—budget an extra 30 seconds per dish.
3. Nostalgia Retro 700W Microwave Oven, Ivory
The ivory retro look that turns a utility appliance into a kitchen conversation piece.
If your kitchen leans vintage or you simply want a microwave that is not another black or stainless box, the Nostalgia delivers on personality with its ivory finish and rounded retro silhouette. It is not just a pretty face—the 700W oven heats quickly and evenly thanks to the rotating glass carousel, and the 8 auto-cook programs take the guesswork out of popcorn, reheat, and defrost.
Ten power levels range from gentle butter melting to full-power reheating, and the size fits dorms and small kitchens. Owners love the color and call it a great value, noting it fits a standard dinner plate or frozen food container without issue. The “two-step door” is the defining quirk: opening requires pressing STOP or cancel first, which prevents kids from yanking it open.
That safety feature is also the most common gripe—several owners find the locking behavior infuriating, and one reported the door breaking when pulled before pressing cancel. The mode is meant to be deactivatable, but the instructions are not always clear, so treat the door gently until you learn the sequence. Compared to the BLACK+DECKER, this one stands taller at 10 inches high versus 9.5, so it needs a bit more vertical clearance.
retro charm appeal
- Owners praise the retro appearance and love having a color option
- Perfect size for dorms and small kitchens, per the feedback
- Quiet operation with fast, even heating
dated performance
- Door lock confuses some—pressing cancel is required to open
- A few reviewers point out the door breaking when forced open
retro vibe: retro-styled kitchens and dorm room setups where looks matter as much as function.
modern needs: you want a standard pull-open door—this one needs the cancel button pressed first.
4. Commercial Chef 0.7 Cu. Ft. Microwave, CHM7MW, White
The no-learning-curve dial microwave that treats your food more gently than most.
This is the pick for anyone who has ever fought a confusing digital keypad. The Commercial Chef uses simple knob controls with a single-ding timer, and owners repeatedly call it easy to operate—several bought it for elderly family members who found other brands too complicated. At 16.9 x 12.4 x 10 inches and 700 watts, it slides into tight counter spots while still fitting larger plates.
The 10 power levels include 6 preset menus, defrost, and 1-6 minute express cook options, and the timer stretches up to 99 minutes for longer tasks. A push-button door lock adds child safety, and the smooth interior wipes clean in seconds. Owners find the slower heating gentler on food, avoiding the leathery texture of high-power units, and the low hum keeps it quiet.
One owner noted the unit is very light and can jerk off the counter when opening the door, so placing a bowl on top solves that. Long-term feedback mentions the baked enamel interior can rust in a few years if you do not keep it dry, so leave the door cracked after steamy cooks. It is the most-reviewed pick on this list by a wide margin, with over 17,000 ratings supporting its reputation.
simple white utility
- Simplicity is the star—no learning curve for any age user
- Single-beep timer and low hum keep it unobtrusive
- Easy-clean smooth interior with dishwasher-safe plate
limited wattage
- Very light—can shift on the counter when opening the door
- Interior rust is a risk if moisture is left trapped inside
basic use: you want the most straightforward, elderly-friendly microwave with no menus to memorize.
power hungry: keep the interior dry and expect gentler, slightly slower heating.
5. Commercial Chef 0.7 Cu. Ft. Microwave, CHM7MS, Stainless
A mirror-finish showpiece that modernizes the kitchen—if you can read the buttons.
Quality is the word owners use most about this stainless sibling—88 positive mentions lead the feedback, and the mirror-like appearance draws consistent compliments for looking far fancier than its price tier. At 17.1 x 12.6 x 10 inches and 700 watts, it offers the same 10 power levels, 6 preset menus, and 99-minute timer as the white CHM7MW, plus a push-button door lock and glass turntable.
Owners love that it “makes my kitchen look modern” and fits most plates and bowls comfortably. The stainless finish means you will want a smudge remover to keep the mirror look pristine—several owners mention this maintenance tip. The child safety lock earns praise from families who want the extra layer of protection.
The honest catch is visibility: the control panel buttons are low-contrast with no backlight, making them hard to read in dim light, and 33 owners flag this as the top negative. Some note that 700W power heats plates hot while food stays cool, which is poor for dense frozen meals. Compared to the white version above, this one runs deeper at 12.6 inches versus 12.4, so measure your counter first.
steel sleek option
- Quality leads at 88 positive mentions—solid build and finish
- Size gets 55 positive mentions for fitting standard plates
- Appearance praised by 51 owners for the modern mirror look
same specs twin
- Buttons are hard to read with no backlight—33 owners flag visibility
- Some find heating uneven for dense frozen meals
steel version: looks matter and you want a stainless microwave that improve a modern kitchen.
duplicate twin: you cook in low light—the unlit control panel will frustrate you nightly.
6. GE Countertop Microwave Oven, 700 Watt, GCST07N1WWW
A famous-name compact with whisper-quiet operation and a brand you already trust.
If brand confidence matters more than saving a few dollars, the GE delivers exactly what the name promises. At 17.31 x 12.74 x 10.1 inches with 0.7 cu ft capacity and 700W power, it fits the tight spaces in dorms, apartments, and offices while offering one-touch express cooking plus 4 convenience cook settings. The digital display and electronic keypad give precise control over time and power.
Quiet is the standout trait in owner feedback—the microwave runs amazingly quietly and closes softly, which matters in a shared space or open-plan apartment. Manual and auto defrost modes thaw frozen food evenly without overcooking edges, and the deactivatable child lock reassures families. GE even specifies airflow needs: 3 inches clearance on each side and above, 1 inch at the rear.
The durability picture is more mixed. While some shoppers say years of reliable service and call it better built than the Commercial Chef, others report breakdowns within months—door issues, turntable grinding, and glitchy buttons for 7, 8, and 9. The 10-inch turntable also limits dish size, and the tiny button lettering is hard to read for some. It is a quality unit when it works, but the reliability split makes it a slightly riskier bet than the BLACK+DECKER above.
trusted brand name
- Amazingly quiet operation with a soft-close door
- Auto defrost adjusts time and power for even thawing
- Deactivatable child lock adds flexibility for families
noisy operation
- Reliability is split—some report breakdowns within months
- 10-inch turntable and tiny button lettering limit usability
brand trust: the GE name, quiet operation, and a unit that fits a 13-inch deep cabinet.
noise concern: the mixed long-term durability reports make the cheaper BLACK+DECKER a safer value pick.
Understanding the Specs
Wattage & Heating Speed
Wattage (power) decides how fast your food heats. These compact models run at 700W, which warms leftovers and drinks in about a minute—noticeably slower than a 1000W+ full-size oven but perfectly fine for dorm and office duty. The trade-off is gentler heating that avoids toughening food.
Capacity vs. Plate Size
Capacity (measured in cubic feet) tells you how much fits inside. At 0.7 cu ft, these microwaves hold a standard 10-inch dinner plate and most frozen food containers, but not a large roasting dish or turkey. If you regularly heat big casserole dishes, step up to a larger capacity.

And for those who prize vintage looks, the Nostalgia Retro in ivory is the one to reach for—just learn its two-step door first.
