What Size Microwave Do You Actually Need?
If you’re standing in front of the microwave section on Amazon.ae wondering whether to go with a compact 20L unit or a bigger 23 to 25L model, the real question isn’t the biggest number available, it’s how much food you actually reheat at once. How many people use the microwave daily and how big the dishes you put inside it are matter far more than any other spec. Let’s break this down with real numbers before you shop the best microwave in the UAE.
The quick answer
For one or two people reheating daily meals or leftovers, a compact 20L unit is plenty. For a family kitchen with bigger dishes or leftovers in bulk, step up to 23 to 25L. Bigger isn’t automatically better: if your counter space is tight and you’ll never fill the extra room, you’re paying for space you don’t use.
Key takeaways
- 20L is enough for one or two people. A compact model like the Midea Solo Microwave 20L or the Panasonic Solo Microwave 20L NN-ST266B covers daily reheating and defrosting without crowding.
- 23 to 25L earns its keep in a family kitchen. The Samsung Solo Microwave 23L or the Panasonic Solo Microwave 25L 900W fit a full dinner plate or a bigger casserole dish without cramming.
- The cavity size changes, not the heating principle itself. A microwave heats food by agitating water molecules inside it regardless of cavity size (general background on the microwave oven, US FDA).
- Counter space is a real constraint. A 25L model needs noticeably more room than a 20L one, so check your available counter space before you buy, not after.
- Size doesn’t change wattage. A smaller unit with higher power can heat faster than a bigger one with lower power, so capacity and wattage are two separate decisions.
How many people actually use the microwave?
Start with this question, not your budget or a brand name. One person living alone who reheats one meal or a portion of leftovers at a time is perfectly comfortable with a compact 20L unit. A couple reheating two small plates or last night’s dinner leftovers usually fits this tier too. The problem only starts once a single dish itself gets bigger: a casserole tray, a full family dinner plate, or a cooking dish too wide to spin freely inside a 20L cavity.
When does stepping up to 23 to 25L pay off?
If your household regularly reheats family-size dishes, or leftovers in bulk after a group meal, 23 to 25L earns the price and counter-space difference. The Samsung Solo Microwave 23L fits a full plate or a bigger dish without crowding, and the Panasonic Solo Microwave 25L 900W goes a step further for anyone regularly cooking for more than two or three people. The simple tell: if you find yourself pulling the plate out and repositioning it mid-cycle because it doesn’t spin freely, that’s a clear sign you need more capacity.
Quick reference: liters by household size
| Household | Recommended capacity | Example from our lineup |
|---|---|---|
| One person, light use | 20L | Midea Solo Microwave 20L |
| Two people, daily reheating | 20L | Panasonic Solo Microwave 20L NN-ST266B |
| Two people or a small family, medium dishes | 20 to 23L | Samsung Solo Microwave 20L (glass door) |
| Family, full dishes or bulk leftovers | 23 to 25L | Samsung Solo Microwave 23L |
| Larger family kitchen, frequent big portions | 25L and up | Panasonic Solo Microwave 25L 900W |
Bigger isn’t automatically better
It’s tempting to assume the biggest microwave you can afford is the safe choice, but that’s not quite right for two reasons. First, a bigger unit needs noticeably more counter space, and in a small kitchen that’s a real daily constraint, not a theoretical detail. Second, capacity doesn’t change heating speed: a 20L model with higher wattage can heat the same plate faster than a 25L model with lower wattage. Match the liters to what you actually put inside, and let wattage be its own separate decision.
Our practical pick for most kitchens
If your household sits in the middle of this range, two people or a small family reheating medium to bigger dishes some of the time, the Samsung Solo Microwave 23L is a practical example that balances capacity and easy cleaning: a ceramic interior that wipes clean more easily than painted steel, a quick-defrost function that’s genuinely useful on busy days, and 23L that fits a full plate. It carries thousands of positive reviews on Amazon.ae, which is exactly why it tops our guide to the best microwave in the UAE. At roughly ≈ 327 AED at the time of writing.

Bottom line
Picking the right microwave size starts with one simple question: how many people actually reheat food from it, and how big is a typical dish? One or two people with simple daily plates are comfortable at 20L, and a family with full dinners or bulk leftovers earns the step up to 23 to 25L. Remember that bigger doesn’t automatically mean better if you’ll never fill it.

Frequently asked questions
What size microwave do I need for one or two people?
A compact 20L model, like the Midea Solo Microwave 20L or the Panasonic Solo Microwave 20L NN-ST266B, comfortably covers daily reheating and defrosting for one or two people. That capacity fits one plate or a medium dish without crowding, and takes up less counter space than the bigger tier.
When do I actually need 23 to 25L?
If you regularly reheat a full dinner plate, a bigger casserole dish, or family-size leftovers, a 23 to 25L model like the Samsung Solo Microwave 23L or the Panasonic Solo Microwave 25L 900W fits that without crowding. For one or two people with small plates, that capacity is usually more than you genuinely need.
Does a bigger microwave always mean better quality?
No. A bigger size just means a wider cavity, not faster heating or better build quality by default. A 20L model with higher wattage can heat the same plate faster than a 25L model with lower wattage. Match the liters to what you actually put inside, not the biggest number on the shelf.
Does counter space actually matter when picking a size?
Yes. A 23 to 25L model needs noticeably more counter space than a 20L model, and that's a real daily constraint in a small kitchen. Check your available counter space before you buy, not after, especially if you're considering the bigger tier.
