Since its invention in 1945, the microwave is still the quickest, most efficient, and most convenient way of heating/making meals all day.

However, other than price and size considerations when purchasing a new microwave, do you normally consider the weight? 

In this article, we take a look at 20L microwaves. How big they usually are and how much they normally weigh.

How much does a 20L microwave weigh

How much does a 20L microwave weigh?

If there were a standard weight for 20L microwaves, it would be 24 pounds. 

Unfortunately, the inconsistency in microwave oven brands and designs makes it tricky to determine the exact weight of a 20L microwave.

Be it countertop, built-in, or over-the-range, the weight of a 20L microwave will range from something like 20 pounds for small compact microwaves to over 50 pounds for larger units.

The table below shows the average weight of the different 20L microwave ovens based on the top brands.

These are indicative figures however and we cannot assume that the dimensions are similar across all 20L microwave ovens. The sizes will vary depending on the type of microwave, the brand, and the style.

Here are a few 20L microwaves from different brands and their dimensions:

  • The 20L Panasonic NN-K18JMMBPQ is 18 inches wide with a height of 10 inches and a depth of 13 inches. (18x10x13)
  •  The 20L Toshiba MM-EM20P(WH) is 13 inches deep, with a height of 10 inches and a width of 17 inches.
  • The 20L Daewoo KOR3000DSL is 11 inches tall with a depth of 14 inches and a width of 19 inches. 
  •  The 20L Russell Hob RHM2076S is 14 inches deep with a height of 10 inches and a width of 17 inches.
  • The 20L Sharp YC-MS02U-S is 13 inches deep with a height of 10 inches and a width of 17 inches.

What is the standard microwave size?

Microwaves come in different types, styles, and sizes, which makes it a little difficult to determine their standard size. 

We can, however, determine the standard microwave size of the various types based on;

  • The external dimensions measured in inches.
  •  The capacity/internal dimensions measured in cubic feet.

Compact countertop microwaves 

These microwaves offer a capacity of around 0.5 to 0.9 cu ft. They are typically 15-19 inches wide with a height of 10-11 inches.

The microwaves have a depth of roughly 12-16 inches when the door is closed. However, with an open door, the depth deepens to 23-30 inches.

Large countertop microwaves

The capacity of large countertop microwaves usually ranges from over 1.0cu.ft and can go up to around 2.2cu. ft.

This type of microwave oven has a width range of  21-25 inches. They are approximately 12-15 inches tall. With a closed door, the depth could range from 16-20 inches, while an open door offers roughly 34-39 inches of deepness.

Built-in microwaves

The interior space of these ovens can range from 1.0 to over 2.0 cu. ft. However, most of them fall between 1.2 to 1.6 cubic feet.

They are approximately 24-30 inches wide, with a height of 17-22 inches. This type of microwave is usually 20-25 inches deep when the door is closed. However, the depth ranges from 30-35 inches when the door is open.

Over the stove microwave

Over-the-range microwaves

Over-the-range microwaves boast of capacity ranging from 0.8cu.ft(compact) to over 2.0cu.ft(full-sized microwaves). They are approximately 30 inches wide with a height of 17 inches.

With a closed door, these microwaves are 15-18 inches deep. The depth stretches to 42-45 inches when the door is open.

How much does a full-size microwave weigh?

The modern microwave oven comes designed to fit into small kitchen spaces, but this has nothing to do with the appliance’s weight.

Generally, the average weight of a standard full-sized microwave across MOST brands ranges between 20 pounds and can go up to 50+ pounds.

Is 20L big for a microwave?

Many microwave ovens most likely have a 20-liter capacity, which is the ideal size since it enables you to strike a balance between your workstation surface and the capacity of the microwave.

A 20L microwave oven is neither big nor small. These microwaves can be an added advantage for small households, couples, and single people. 

This fantastic appliance’s one drawback is that they are less likely to fit huge dinner tables. When you wish to cook a lot of food, this presents a significant inconvenience.


Here is a summary of everything we’ve discussed above:

  • A 20L microwave can weigh anything from 20 pounds to more than 50 pounds, depending on the model and brand.
  • Depending on the manufacturer and design of the microwave oven, a typical 20L microwave has an internal capacity of 0.5 cu. ft. (for tiny, compact appliances), and up to 1.0+ cu. ft. (for bigger units).
  • The external dimensions of a 20L microwave oven are 17” by 15” by 11”. 
  • Most microwave ovens deliver a capacity of  20 liters. This size is neither small nor big. It is ideal for small households and single people who do not need to cook large quantities of food.
