What Size Microwave Do I Need?

There is no one-size-fits-all answer to this question, as the size of microwave you need will depend on a number of factors, including the size of your kitchen, the amount of food you typically cook, and your personal preferences.

However, here are a few general guidelines to help you choose the right sized microwave for your needs:

🔸 If you have a small kitchen or limited counter space, a compact or mini microwave might be the best option for you.

These models are usually about 18 inches wide and 14 inches deep, making them easy to fit into tight spaces.

🔸 If you do a lot of cooking for large groups of people, or if you frequently make big meals, a full-sized microwave is a better option.

These models are typically about 24 inches wide and 16 inches deep, so they have plenty of room to accommodate larger dishes.

🔸 If you want a microwave that can do it all, consider a convection microwave.

These models combine the features of a traditional microwave with those of a convection oven, so they’re perfect for cooking large meals or for browning and crisping food.

Convection microwaves are usually about 30 inches wide and 18 inches deep.

No matter what size microwave you choose, make sure it has the features you need, such as a turntable, defrost function, and adjustable power levels.

And be sure to read the reviews before making your purchase to see what other customers have to say about the model you’re considering.

Things to Determine While Selecting a Microwave’s Size

When it comes to microwaves, size really does matter. If you have a small kitchen, you’ll want a compact model that doesn’t take up a lot of counter space.

On the other hand, if you have a large family, you’ll need a larger model that can accommodate big dishes. 

Here’s a look at some of the factors you’ll need to consider when choosing a microwave oven.
1️⃣ How much space do you have?

The first thing to consider is how much space you have in your kitchen. If you have a small kitchen, you’ll want a compact model.

These models are usually about 18 inches wide and 14 inches deep. They’re also usually about half the size of a full-sized microwave.

2️⃣ How many people do you need to feed?

If you have a large family, you’ll need a larger microwave. These models can be up to 24 inches wide and 16 inches deep. They can also hold more food than compact models.

3️⃣ What type of food do you want to reheat?

If you only want to reheat small dishes, a compact model will probably be fine. But if you want to reheat large dishes, you’ll need a larger model.

4️⃣ What are your power needs?

Microwaves come in different wattage ratings. The higher the wattage, the faster the microwave will cook.

If you have a lot of food to reheat, you’ll need a high-wattage microwave.

5️⃣ What other features do you want?

Some microwaves come with special features, such as defrost functions and turntables. If you want these features, you’ll need to choose a model that has them.

Once you’ve considered all of these factors, you should have a better idea of what size microwave you need.

Remember, the size of the microwave is important, but so are the features. Be sure to choose a model that has the features you need and the size that’s right for your kitchen.

Why Is Microwave Oven Size Important?

One of the most important factors to consider when purchasing a microwave oven is the size. Microwave ovens come in a variety of sizes, from small countertop models to large built-in ovens.

The size of the oven you need will depend on several factors, including the amount of space you have available, the number of people you plan to cook for, and the types of foods you plan to prepare.

1️⃣ Small microwaves are typically between 0.5 and 1.0 cubic feet in size.

Smaller microwaves are generally more energy efficient than larger models and can be a good choice for those who have limited counter space. They are also typically less expensive than larger models.

However, they may not have all the features that larger microwaves offer, such as convection cooking or grill functions.

2️⃣ Medium microwaves are typically between 1.0 and 2.0 cubic feet in size.

Medium-sized microwaves are a good choice for most people. They offer plenty of space for cooking multiple items at once and usually have all the features that smaller models do.

3️⃣ Large microwaves are typically 2.0 cubic feet or larger in size. 

Large microwaves are great for families or those who entertain often. They have enough space to cook large meals and can even accommodate larger dishes.

Most large microwaves also have convection cooking capabilities, which allow you to bake or roast food in addition to heating it.

4️⃣ Extra-large microwaves are the largest size available and are typically only found in commercial kitchens.

They offer an incredible amount of space and have all the features of smaller and medium-sized models.

When choosing a microwave oven, it is important to consider the size of the unit in relation to the amount of space you have available.

If you have a small kitchen, a countertop model may be the best option. If you have a larger kitchen, a built-in oven may be the better choice.

And if you entertain often or have a large family, an extra-large microwave may be the best option for you. No matter what size microwave oven you choose, make sure it is big enough to meet your needs.

🔸 More than 1,000 watts: 1.2 – 1.5

How Are The Sizes of Microwaves Measured?

The size of a microwave is typically measured in cubic feet. This measurement tells you the amount of space inside the oven that is available for cooking food.

To find the cubic footage of a microwave, simply measure the length, width, and height of the interior of the oven in inches and multiply those numbers together.

For example, if a microwave has an interior that measures 20 inches long by 16 inches wide by 12 inches tall, it has a total volume of 3.84 cubic feet.

Cubic footage is not the only way to measure a microwave’s size, however. Some manufacturers also use external dimensions, such as width x depth x height.

For example, a microwave that measures 20 inches wide by 16 inches deep by 12 inches tall would have an external dimension of 2.0 cubic feet.

It is important to note that the size of a microwave oven does not necessarily indicate how much food it can hold. The capacity of a microwave is typically measured in quarts, which tells you how much food the oven can accommodate.

For example, a microwave with a capacity of 1.0 cubic foot can hold up to four quarts of food. A microwave with a capacity of 1.5 cubic feet can hold up to six quarts of food, and so on.

How To Measure The Space You Have For A Microwave

Now that you know “What size microwave do I need?”, it’s time to measure the space you have for it.

You’ll need to measure the width, depth, and height of the space where you want to put the microwave.

  • To measure the width, use a tape measure to find the distance between the two inside edges of the cabinets or shelves where you want to put the microwave.
  • To measure the depth, use a tape measure to find the distance from the front edge of the cabinet or shelf to the back wall.
  • And to measure the height, use a tape measure to find the distance from the top of the cabinet or shelf to the ceiling.

Once you’ve measured all three dimensions, write them down so you’ll remember them when you’re shopping for microwaves. And be sure to measure the space more than once to make sure you have accurate measurements.

Now that you know how to measure the space you have for a microwave, it’s time to start shopping. Be sure to keep the size and power needs of your kitchen in mind as you choose the perfect model for your home.

What To Consider Other Than A Microwave’s Size

When choosing a microwave oven, size is not the only thing to consider. You also need to think about the features you want and the power level you need.

Here are some other things to keep in mind as you shop for a new microwave:

1. Power Level

The power level of a microwave oven is measured in watts. The higher the wattage, the more powerful the oven.

Most home microwaves have a power level between 600 and 1,200 watts.

2. Cooking Modes

Most microwaves come with several cooking modes that make it easier to cook specific types of food.

For example, many models have a defrost setting that thaws frozen food quickly and evenly.

Some models also have a sensor cooking mode that adjusts the cook time based on the amount of moisture in the food.

3. Timer

A timer is a handy feature that allows you to set the microwave to start and stop cooking at specific times.

This is convenient if you need to cook food for a certain amount of time but don’t want to be in the kitchen to monitor it.

4. Controls

Most microwaves have push-button controls that allow you to select the power level, cooking time, and other settings. Some models also have dial controls or touchscreen panels.

5. Display

The display on a microwave oven shows the current time, cook time, and other information. Some displays are digital, while others are analog.

6. Door

Microwave doors can be made of glass, plastic, or metal. Some models have a see-through door that allows you to check on the food as it cooks.

7. Interior Light

Many microwaves have an interior light that turns on when the door is opened. This makes it easier to see the food inside the oven.

8. Ventilation System

Most microwaves have a ventilation system that helps to keep the oven cool and prevents the build-up of heat.

Some models have an exhaust fan that vents the air outside, while others have an internal fan that circulates the air inside the oven.

9. Price

Microwave ovens range in price from about $30 to $500. The price depends on the size, power, and features of the oven.

10. Warranty

Most microwaves come with a warranty that covers the cost of repairs or replacement if the oven is damaged.

Some manufacturers also offer extended warranties that cover the cost of repairs or replacement for a longer period of time.

Now that you know what to look for in a microwave oven, it’s time to start shopping. Be sure to compare the features and prices of different models before you make your final decision.
