And since we know that choosing a microwave with the right capacity isn’t an easy task, we’ve prepared this guide for you.

Here, we’ll help you figure out the ideal microwave capacity for your household, among other considerations. Keep reading.

Ideal Capacity for Microwave Ovens

To figure out the capacity of the microwave (measured in liters) you need for your home, consider the size of your family. The larger the family, the higher the capacity and vice versa.

Always choose a microwave with the best capacity to suit your cooking needs as follows.

  • 15 – 20 liter: Solo microwave that is best suited for a family of 2 to 4 members.
  • 21 – 25 liters: Grill microwave/convection microwave for a family of 2 to 4 members.
  • 25 – 30 liters: Solo microwave that is best suited for a bigger family of 4 to 6 members.
  • 32 liters and above: Grill microwave or convection microwave for a family of 4 to 6 members.

Other Factors to Consider Before Buying a Microwave

How Many Liters Microwave Should I Buy

1. Microwave Type

The most challenging part of purchasing a microwave is making the choice of the type to go for. There are 3 types of microwaves available in the market, including solo, grill, and convection microwaves.

A solo microwave is the most basic model and is excellent for simple reheating, cooking, and defrosting. You can, however, not grill or bake with this microwave.

With a grill microwave, you can cook simple meals like pasta, rice, brew coffee, make popcorn, among others. It comes with additional grilling accessories to help you grill meat and soft vegetables.

A convection microwave is ideal for baking and grilling. It can also perform all the tasks of a solo microwave, roast, grill, bake, brown and crisp foods.

If looking for a microwave that does more than simple cooking, a convection model is the best option for you.

2. Wattage

The wattage of most microwaves ranges between 600 to 1200 watts. One basic rule to remember is, the higher the microwave’s wattage, the quicker the cooking time.

And another thing, get a microwave with flexible power settings.

To decide the power setting to settle for, you need to analyze your cooking habits first. If all you do is some basic cooking, an 800 watts microwave oven will suffice.

However, if you usually prepare meals in bulk or have a large family, invest in one with a higher power setting (from 900 watts) for optimum use.

3. Durability

What’s the lifespan of the microwave you intend to buy? The most durable microwaves usually have a shelf life of around 10 to 12 years.

It’s very important that you buy a microwave that will last for the longest time possible. To ascertain this, take some time to read customer reviews before paying for the appliance.

4. Noise Level

Some microwaves make a very loud beep with each button press when the cooking time is up or if you don’t open the oven’s door immediately after cooking.

These beeps can be very annoying and can be a nightmare for fussy kids. You also don’t want to wake your loved ones with these beeps as you prepare breakfast early in the morning.

If purchasing the microwave online, you won’t have the chance to try it out, hence the need to go through customer reviews, which often mention it when a model is particularly noisy. You’ll therefore know the one to avoid.

5. Child Safety Lock

If you have kids, ensure that the microwave you settle for has a safety lock. Kids are playful, and there might be accidents should they put their hands in the oven.

With the safety lock, your kids can’t have access to the microwave. It minimizes the risk of somebody getting hurt or a fire from starting.

6. Panel Type

There are 3 types of microwave control panels, namely tact dial, mechanical, and feather touch.

Mechanical and tact dial panels are usually standard in low-end models and can actually handle rough usage.

Feather-touch panels add to the microwave’s design and can sense your fingers. This panel type is usually common in high-end models.

Additional Features

Nowadays, most microwaves offer a variety of features that help simplify the cooking process. Some of the must-have features to look out for include automatic defrost, preheat, and pre-programmed settings.

An auto-cook menu comes in handy for amateurs in cooking, while a timer enables you to configure the cooking duration.

7. Price

You need to consider the price of every appliance before making the order. When it comes to microwaves, price ranges vary considerably depending on the type you decide to invest in.

Luckily enough, you will most likely get a model within your budget since these appliances have budget-friendly options as well. At as low as $150, you can get yourself a microwave for basic cooking.

8. Warranty

Do not purchase a microwave without a warranty. This should be the case for when you are buying any other appliance.

Check for the components covered by the warranty and the warranty period as well. The longer the period, the better.
