A countertop microwave is judged on size, how evenly it heats, and how simple it is to use. Capacity has to match both your food and your counter, inverter models reheat more evenly than standard ones, and sensor cooking takes the guesswork out. We compared five microwaves from a tiny 0.7 cubic foot to a 3-in-1 that also air fries, and matched each to the kitchen it suits. We did not run a heating-uniformity lab, so each score is a research-based composite from manufacturer specifications and owner feedback.
For most kitchens the Toshiba EM131A5C is the best all-rounder: a family-sized 1.2 cubic feet, sensor cooking and a clear interface. Want the most even reheating? The Panasonic inverter. Tight on space or budget? The compact COMFEE 0.7 is the value pick.

How We Evaluated These Picks
We are a research desk, not a lab, so we did not map heating uniformity with instruments. We compared usable capacity against footprint, whether the microwave uses inverter or standard power, sensor and preset features, controls, and long-run owner feedback. The composite score is weighted as follows.
- Heating performance and evenness: 30%
- Capacity and footprint: 25%
- Features (sensor, presets): 20%
- Controls and ease of use: 15%
- Value: 10%
Inverter vs Standard, and Sizing to Your Counter
The biggest quality difference is inverter versus standard power. A standard microwave makes lower power settings by switching full power on and off, which can overcook edges while the center stays cold. An inverter, like the Panasonic and Breville here, delivers steady lower power, so defrosting and reheating are gentler and more even. It is the single feature most worth paying for if you reheat a lot.
Size is the other real choice, and it is a trade-off with your counter. Compact 0.7 to 0.9 cubic foot models suit small kitchens and one or two people but will not fit a large dinner plate comfortably. Family-sized 1.1 to 1.2 cubic foot models fit bigger plates and dishes but take real space. Measure your counter and check that a dinner plate turns freely before you buy.
Best Overall: Toshiba EM131A5C 1.2 cu ft
Research-based composite: 9.1 / 10 · Best for: Most families who want a roomy, easy microwave with sensor cooking
Specifications
| Capacity | 1.2 cu ft |
| Power | 1100 W standard |
| Feature | Sensor cooking |
| Extra | Mute option |
| Best for | Families |
| Turntable | Yes |
The Toshiba EM131A5C is the microwave most kitchens should buy. Its 1.2 cubic foot capacity fits large plates and dishes, sensor cooking adjusts time and power automatically for common foods, and the interface is clear and easy, with a handy mute option for the beeps. At 1100 watts it heats quickly and evenly for a standard microwave.
It is a standard, not inverter, microwave, so very gentle reheating is less even than the Panasonic, and it takes real counter space. But for capacity, features and value it is the strongest all-rounder. Who should skip it: small kitchens or anyone who wants inverter evenness. Pros: family-sized, sensor cooking, easy controls, mute option. Cons: standard power, takes space.

Best Inverter for Even Heating: Panasonic 1.2 cu ft
Research-based composite: 9.0 / 10 · Best for: Cooks who reheat and defrost a lot and want the most even results
Specifications
| Capacity | 1.2 cu ft |
| Power | Inverter |
| Benefit | Even reheat and defrost |
| Best for | Even results |
| Turntable | Yes |
| Brand | Panasonic |
The Panasonic uses inverter technology, which is its key advantage. Instead of pulsing full power, it delivers steady lower power, so defrosting thaws evenly without cooking the edges and reheated leftovers warm through without hot and cold spots. The 1.2 cubic foot capacity fits family dishes, and it heats strongly at higher wattage.
It costs a little more than a standard microwave of the same size and takes similar counter space. But if you reheat and defrost often, the even results are worth it. Who should skip it: anyone who mainly boils water or reheats simply and does not need inverter evenness. Pros: even inverter heating, family-sized, strong power. Cons: pricier than standard, takes space.

Best Premium 3-in-1: Breville Combi Wave
Research-based composite: 9.0 / 10 · Best for: Cooks who want one appliance that microwaves, air fries and bakes
Specifications
| Capacity | 1.1 cu ft |
| Power | Inverter |
| Modes | Microwave, air fry, convection |
| Build | Premium |
| Best for | 3-in-1 |
| Brand | Breville |
The Breville Combi Wave replaces three appliances. It is an inverter microwave for even reheating, an air fryer for crisping, and a convection oven for baking, all in one unit, which saves counter space overall if you would otherwise own separate machines. The build quality and controls are a clear step above standard microwaves.
It is expensive and physically large, and it is only worth it if you will use the air-fry and convection modes. But as a premium do-everything box it is genuinely capable. Who should skip it: anyone who only needs a basic microwave, or who is on a budget. Pros: inverter microwave plus air fry and convection, premium build. Cons: expensive, large, overkill for basic use.

Best Compact: Black+Decker 0.9 cu ft
Research-based composite: 8.4 / 10 · Best for: Small kitchens and apartments that want a capable microwave with a small footprint
Specifications
| Capacity | 0.9 cu ft |
| Power | 900 W standard |
| Size | Compact, fits a plate |
| Best for | Small kitchens |
| Controls | Simple |
| Brand | Black+Decker |
The Black+Decker 0.9 cubic foot is a well-judged compact microwave. It is small enough for apartment counters and dorms yet still fits a standard dinner plate, unlike the tiniest models, and its 900 watts heat everyday food quickly. Simple presets and a clear dial-and-button interface keep it easy to use.
It is a standard microwave, so gentle reheating is less even than an inverter, and 0.9 cubic feet is tight for large dishes. But as a compact everyday unit it balances size and capability well. Who should skip it: families needing more room or wanting inverter power. Pros: compact yet fits a plate, quick heating, easy controls, affordable. Cons: standard power, tight for big dishes.

Best Small Budget: COMFEE 0.7 cu ft
Research-based composite: 8.1 / 10 · Best for: Dorms, offices and tight budgets that need a basic microwave for the essentials
Specifications
| Capacity | 0.7 cu ft |
| Power | 700 W standard |
| Feature | Eco mode |
| Best for | Dorm, budget |
| Size | Very compact |
| Brand | COMFEE |
The COMFEE 0.7 cubic foot is the small, cheap option that covers the basics. It is tiny enough for a dorm, office or the smallest kitchen, its 700 watts handle reheating, drinks and simple cooking, and an eco mode trims standby power. Preset buttons and a compact body make it a fuss-free unit for one person.
At 0.7 cubic feet it will not fit a large dinner plate, and 700 watts is slower, so recipes written for higher wattage need more time. But for the price and size it does exactly what it should. Who should skip it: anyone cooking full meals or reheating large dishes. Pros: very compact, cheap, eco mode, simple. Cons: small capacity, low wattage, slower.

Which Microwave Should You Buy?
Best for a family
The Toshiba EM131A5C at 1.2 cubic feet with sensor cooking, or the Panasonic if you want inverter evenness at the same size.
Best for even reheating and defrosting
An inverter model, the Panasonic or the Breville Combi Wave, which deliver steady low power instead of pulsing full power.
Best for a small kitchen
The Black+Decker 0.9 cubic foot, compact but still able to fit a dinner plate, or the tiny COMFEE for the smallest spaces.
Best to replace several appliances
The Breville Combi Wave, which microwaves, air fries and bakes in one box.
Best on a budget
The COMFEE 0.7 for the lowest cost and smallest size, or the Black+Decker for a bit more room.
Buying Guide
Match capacity to your plates and counter
Compact 0.7 to 0.9 cubic foot units suit small spaces but may not fit large plates; 1.1 to 1.2 cubic foot models fit family dishes but take real space. Check a plate turns freely.
Inverter is worth it if you reheat a lot
Inverter power reheats and defrosts more evenly than standard pulsing power. If leftovers and defrosting are a big part of your use, prioritise it.
Sensor cooking adds real convenience
Sensor cooking measures steam and adjusts time and power automatically, so common foods heat without guesswork. It is a genuinely useful feature.
Wattage affects speed
Higher wattage, around 1000 to 1200, heats faster and matches most recipes. A 700-watt unit is slower and needs longer times.
Care and Use
- Wipe the interior after spills so food does not burn on and cause odors or arcing.
- Cover food to reduce splatter and help it heat evenly.
- Keep the waveguide cover and walls clean to prevent sparking.
- Give the vents clearance and do not run the microwave empty.
Frequently Asked Questions
Is an inverter microwave better than a standard one?
For reheating and defrosting, yes. An inverter delivers steady low power for even results, while a standard microwave pulses full power, which can overcook edges. For simple boiling and reheating, a standard model is fine.
What size countertop microwave do I need?
Compact 0.7 to 0.9 cubic foot units suit one or two people and small counters; 1.1 to 1.2 cubic foot models fit family dishes and large plates. Measure your counter and check a plate turns freely.
How many watts should a microwave have?
Around 1000 to 1200 watts heats quickly and matches most recipes. A 700-watt unit is cheaper and smaller but slower, so foods need longer cooking times.
What is sensor cooking on a microwave?
Sensor cooking detects the steam from food and automatically adjusts the time and power, so common dishes heat through without you guessing the settings. It is a convenient, accurate feature.
