The right microwave size isn’t just about the liters of the interior cavity, it’s about how you actually use it: do you reheat one plate a day, or dishes and casseroles for a full family, or do you also want grill cooking that needs a bit more interior room? The quick answer: one or two people are covered by a compact 20-liter solo unit, while a family of 3 or more usually needs 25 liters or up, especially if a grill function matters too.
The quick answer
Match the microwave’s capacity to your household size and the dishes you actually reheat, not the biggest number on the shelf. One or two people with individual meals: a compact 20L solo unit. A family of 3-4 that also wants grill cooking: a 20-25L grill or 3-in-1 model like the Toshiba MW3-AG20PE. A bigger household with large dishes and casseroles: 29 liters or more. All prices are approximate and change, so check Amazon.sa before you buy.
Key takeaways
- “Size” in a microwave means capacity in liters plus function: a small solo unit for individual reheating, or a bigger grill unit that needs extra interior room for the heating element.
- A 20-liter solo unit suits one or two people reheating individual meals daily, with no need to pay for extra capacity that sits half empty.
- Grill and 3-in-1 microwaves usually start at 20 liters because the extra heating element needs a bit more interior space to work efficiently.
- 25 liters or more is only necessary when you cook for a full household or use large casserole dishes, otherwise you’re paying for capacity you won’t use.
- Wattage matters too, not just capacity: a higher-power unit reheats faster and more evenly, especially with frequent daily use.
How much does your kitchen actually need?
If you live alone or with a partner and mostly reheat individual meals or defrost small amounts, a compact 20-liter solo unit is usually plenty, since you don’t need extra interior room for a single plate. If your household has 3 or more people and regularly reheats multiple dishes or needs to defrost larger amounts, 25 liters saves you from reheating in two batches. And if you also want grill cooking to brown cheese or crisp a dish’s surface, go straight for a 20-liter-plus grill model, since that category is built with the extra heating element in mind from the start.
Capacity alone isn’t enough: function matters too
Unlike an appliance like a refrigerator where liters decide almost everything, a microwave is different because the function itself, solo, grill, or 3-in-1, decides what you can actually do with the unit, not the cavity size alone. A 20-liter solo unit reheats and defrosts efficiently, but it won’t brown or crisp a dish’s surface no matter how big its capacity is. A grill unit at the same 20 liters adds that ability, but needs a bit more cleaning because of grill splatter. That’s why our guide to the best microwave in Saudi Arabia ranks picks by category and capacity together, not just by the liter number alone.
Quick reference: size by household size
| Your household | Suitable capacity | Example from our shortlist |
|---|---|---|
| One person, basic reheating only | 20L solo | Nikai 20L 700W Solo, ≈ 200 SAR |
| One or two people, digital controls | 20L digital solo | Clikon 20L Digital Solo, ≈ 245 SAR |
| Family of 3-4, wants grill cooking too | 20-25L grill or 3-in-1 | Toshiba MW3-AG20PE 20L, ≈ 720 SAR |
| Bigger household, large dishes or casseroles | 29L grill or 30L solo | Hisense 29L Grill Microwave, ≈ 500 SAR |
What if you also want grill cooking?
If you already know you want browning or crisping alongside regular reheating, don’t just compare capacity among solo models. Go straight to the grill or 3-in-1 category at 20 liters or up, since that tier is well represented in Saudi Arabia through Toshiba, LG, and Hisense at varying prices and capacities. Our solo vs grill microwave guide breaks this trade-off down further if you’re still undecided.
The choice that covers most Saudi kitchens
For most households here that want genuine flexibility without committing to the biggest capacity available, the Toshiba MW3-AG20PE 3-in-1 at 20 liters covers this range: everyday reheating plus grill and convection if you occasionally want browning, at roughly ≈ 720 SAR at the time of writing with thousands of positive reviews on Amazon.sa. We didn’t pick it for the largest capacity, we picked it because its size and function match what most Saudi kitchens actually need, which is why it tops our guide to the best microwave in Saudi Arabia.

Figure out your size in one minute
- Ask yourself: do you mostly reheat individual meals, or dishes and casseroles for a full family?
- One or two people with individual reheating: go for a 20L solo unit.
- A family of 3-4, or you want grill cooking: go for a 20-25L grill model.
- A bigger household or large casserole dishes: go for 29 liters or more.
- Check microwave prices in Saudi Arabia to match the tier to your budget, and remember prices are approximate and change.
Bottom line
The right microwave size is the one that matches your household size and the dishes you actually reheat, not the biggest capacity you can find. One or two people with individual reheating: a 20L solo unit. A medium household that also wants grill cooking: 20-25 liters. A bigger household with large dishes: 29 liters or more.

Frequently asked questions
What size microwave do I need for one or two people?
For one or two people reheating mostly individual meals, a compact 20-liter solo unit is usually plenty, and you don't need to pay for extra capacity that will sit half empty most of the time.
Do I need a bigger capacity if I also want grill cooking?
Not by a huge margin, but grill and 3-in-1 microwaves usually start at 20 liters and go up to 25 or 29, because the extra heating element needs a bit more interior room to work efficiently around the dish.
When do I actually need 25 liters or more?
When you regularly cook for a family of 3 or more, or need to fit large dishes and family-size casseroles in one go instead of reheating them in two batches.
Does a bigger microwave always mean a better choice?
No. A large microwave for one person means wasted counter space and more cleaning for capacity you won't actually use. The right size is the one that matches how many people you're reheating for and what dishes you actually use, not the biggest number on the shelf.
Is capacity alone enough, or does wattage matter too?
Both matter. Solo models in this category start at 700W, while grill and premium units go up to 900W. Higher power reheats faster and more evenly, which matters if you use the unit several times a day, but it's secondary to matching capacity to how you actually use it.
