The best compact microwave is the one that fits your measured countertop and your everyday dishware. Measure available width, height and depth first, then check the manufacturer’s ventilation and clearance instructions. Among the documented options here, Panasonic’s NN-SB438S is the only model presented as a current compact option; the two GE models are useful size references but are marked no longer manufactured.
Measure the space before choosing a compact microwave
A capacity label such as 0.9 cubic feet or 20 litres does not tell you whether an appliance will fit. Record the maximum countertop width, height and depth, including space needed for the door to open and for airflow around the cabinet. Then compare those measurements with the appliance’s external dimensions.
Read the exact user manual for clearance and ventilation requirements before installation. The product pages cited here do not establish one universal clearance rule, so do not assume that “compact” means it can be pushed tightly against a wall or placed beneath every cabinet.
Check the shape of the available space
- Measure at the narrowest points, including backsplash trim, side walls and overhanging cabinets.
- Leave room to reach the controls and open the door without hitting a wall or another appliance.
- Confirm that the outlet and cord routing will not force the microwave into an unsafe position.
Compact microwave models compared
The dimensions below come from official manufacturer pages. Panasonic lists dimensions as width × height × depth; GE presents height × width × depth on its product pages, so the table normalizes the order for easier comparison.

Panasonic NN-SB438S: the documented current compact choice
Panasonic lists the NN-SB438S as a 0.9-cubic-foot, 900-watt countertop microwave measuring 19.1 inches wide, 11.5 inches high and 14.8 inches deep. Those are manufacturer specifications, not independent cooking-performance results.
Listed controls and programs

- Timer and delay-start functions
- More/less control
- Child safety lock
- Keep-warm function

Its dimensions should be compared with your counter before purchase, and live stock and price should be confirmed because retail information can change.

What capacity means in a small kitchen
Choose capacity around the plate, bowl or storage container you actually use. A stated cavity volume is not a substitute for checking the usable interior or turntable diameter; two microwaves with the same nominal capacity may accommodate dishes differently.

Panasonic’s UK buying guide says a compact microwave under 25 litres can suit one or two people in a smaller kitchen and gives 20-litre models with external dimensions of 440 × 324 × 258 millimetres. That is manufacturer guidance for the UK market, not a universal rule for every household or region. Read Panasonic UK’s sizing guidance.

Match the cavity to your routine
- Single portions and mugs: a smaller cavity may be sufficient if your dishes fit the turntable.
- Dinner plates: measure the plate’s diameter and compare it with the usable turntable area.
- Rectangular containers: check door and cavity clearance, not just the advertised cubic-foot figure.
- Two-person use: Panasonic’s under-25-litre guidance can be a starting point, but your cookware dimensions decide the practical fit.
Power and controls: compare specifications, not promises
Wattage is the manufacturer’s listed output specification. The Panasonic model is listed at 900 W and the GE JE610BF at 650 W; the reviewed GE JES1095BMTS page excerpt does not state output. Do not treat a higher number alone as proof of more even cooking or shorter times, because actual results also depend on food, container, starting temperature and program.
For everyday convenience, compare whether the control panel includes the functions you will use: one-touch presets, a quick-add button, timer, child lock, delay start or keep-warm. Preset names and counts are model-specific, so verify them in the manual or product listing rather than assuming every compact microwave has the same menu.
Rank #4

Availability matters more than a small dimensional advantage
GE identifies both the JE610BF and JES1095BMTS as no longer being manufactured. A retailer may still show old inventory, but listing pages can be stale, refurbished or for a different suffix. Confirm the exact model number, condition, warranty and return policy before paying.

A practical buying checklist
- Measure: write down the usable countertop width, height and depth.
- Check installation: open the manual and follow its clearance, ventilation and electrical instructions.
- Measure your cookware: record the diameter of your main plate and the footprint of your largest container.
- Shortlist by footprint: compare external dimensions in the same W × H × D order.
- Compare useful specifications: review listed wattage, controls, presets, timer functions and safety lock.
- Verify stock: confirm the exact SKU, availability, condition and warranty immediately before ordering.
- Recheck the delivered unit: do not install it if the dimensions, model number or manual differ from the listing.
Which option fits which situation?
You need the smallest documented footprint
The GE JE610BF has the smallest cited exterior dimensions and a 0.6-cubic-foot cavity, but its manufacturer-discontinued status makes it a reference point rather than a dependable current recommendation.
You want more listed capacity and power
The Panasonic NN-SB438S combines a 0.9-cubic-foot capacity with listed 900-watt output and documented presets. It still requires a 19.1 × 11.5 × 14.8-inch space plus the manual’s required clearances.
You are comparing a similar GE size
The GE JES1095BMTS is close to Panasonic in external size and capacity, but GE also marks it no longer manufactured and the reviewed excerpt does not state its output. Verify availability and specifications rather than treating it as an equivalent substitute.

Start with the tape measure, not the capacity label. If the Panasonic NN-SB438S fits your measured space and your dishes, it is the clearest documented current option in this comparison. The GE models demonstrate how small a footprint can be, but their discontinued status means they should not be recommended without confirming legitimate, supported stock.
