How Are Dishwashers Measured?

Dishwashers are measured in a few different ways, but the most critical measurement is width. Dishwasher widths start at 18 inches and can go up to 36 inches. The average dishwasher width is 24 inches.

The following important measurement is height. Dishwasher heights also start at 18 inches, but they can be as tall as 46 inches. The average dishwasher height is 34 inches.

Finally, dishwashers are also measured by the size of their interior cavity. This is important because it determines how many dishes the dishwasher can hold. Interior cavities start at around 4.5 cubic feet and can go up to 16 cubic feet. The average dishwasher interior cavity is 9 cubic feet.

If you’re planning to buy a dishwasher, it’s essential to make sure that you choose one that will fit well in your kitchen. To do this, you’ll need to measure the space where the dishwasher will go.

Here’s how to measure a dishwasher:

1. First, measure the width of the space. You’ll need to know the width of the dishwasher and the width of the doorway or opening that it will need to fit through.

When measuring the width of the space for your dishwasher installation, use a tape measure to get an accurate measurement. Start by measuring the widest point of the space and then compare that measurement to the dimensions of your dishwasher. If the space is too small, you may need to look at alternative locations or consider a different dishwasher model. When measuring the width of the space, make sure to account for any obstacles or protrusions that could block the dishwasher door from opening fully. Once you have the measurements, write them down so you can reference them later when shopping for your dishwasher.

2. Next, measure the height of the space. The dishwasher must be tall enough to fit under your countertop, so measure from the floor to the countertop.

There are a few things you’ll need to take into consideration when measuring the height of the space for your dishwasher installation: 

– The height of your countertop. 

– The size of your dishwasher (most standard dishwashers are about 24″ tall, but please double check the dimensions of your particular model). 

– Whether or not you need to leave space for a dishwasher air gap. 

To measure the height of your countertop, use a tape measure or ruler and measure from the floor to the top of the counter. Once you have that measurement, add the height of your dishwasher and any additional space needed for an air gap (if required). That will give you the total height you’ll need for your dishwasher installation. 

3. Finally, measure the depth of the space. This is important because you’ll need to ensure that the dishwasher can be appropriately connected to your water and drain lines.

There are a few different ways to measure the depth of the space for dishwasher installation, but one of the simplest is to use a tape measure. Start by finding the widest point of the space and measuring from front to back. Then, do the same thing at the narrowest point. The difference between these two measurements is the depth of the space. If you’re unsure how much space you need for installation, it’s always best to err on caution and go with a slightly larger measurement to be safe. 

Another way to measure the depth of the space is to use a level. Place the level at the front of the space and ensure it is level. Then, mark the top of the level with a pencil. Next, move the level to the back of the space and mark the top of the level again. The distance between these two marks is the depth of the space. 

Once you have these measurements, you can narrow down your choices and find the perfect dishwasher for your kitchen.

What Size Dishwasher Do I Need?

Now that you know how dishwashers are measured, you can start to narrow down your options. The first thing you need to consider is the size of your kitchen. You’ll probably want a smaller dishwasher if you have a small kitchen. On the other hand, if you have a large kitchen, you might be able to accommodate a larger dishwasher.

Another thing to consider is the number of people in your household. You’ll need a dishwasher with a larger interior cavity to hold your dishes if you have a large family. If you only have a few people in your household, you can get away with a smaller dishwasher.
Finally, think about how often you entertain guests. If you have a lot of people over for dinner parties or other gatherings, you might need a larger dishwasher to clean all of your dishes at once.

Now that you know how dishwashers are measured and what size you need, you can start shopping for your perfect dishwasher. Don’t forget to consider the other features you might want, such as a built-in water softener or a heated dry cycle. With these factors in mind, you can find the perfect dishwasher for your home.

Examples of Some Suitable Space Sizes for a Dishwasher

-A full-size dishwasher usually needs a space about 24 inches wide, 38 inches high, and 27 inches deep.
-A slimline or compact dishwasher is usually about 18 inches wide, 35 inches high, and 22 inches deep.
-An under-the-counter dishwasher is typically 24 inches wide, 34 inches high, and 25 inches deep.
-A portable dishwasher is usually 18 inches wide, 36 inches high, and 28 inches deep.
-A built-in dishwasher is typically 24 inches wide, 34 inches high, and 25 inches deep.

When choosing a dishwasher, measure the space in your kitchen to ensure it will fit. You will also need to make sure there is a water line and an electrical outlet nearby. Dishwashers typically require a 120-volt, 20-amp circuit.
As you can see, the size of the space you need for your dishwasher will depend on the capacity of the dishwasher. Make sure to take measurements of your kitchen space before shopping for a dishwasher to know what size will fit in your kitchen.

Does a Dishwasher Need Space Around It?

No, a dishwasher does not need space around it. You can install a dishwasher in a tight space as long as there is enough clearance for the door to open and close properly. However, you may want to leave some extra space around the dishwasher for easier access when loading and unloading dishes.

To make sure you have plenty of room for loading and unloading, keep at least 26 inches of open space in front of the dishwasher. If you are going to install your dishwasher in a corner location, give it at least 2 inches of space between the edge of the door opening and the wall or cabinet.

What is the Distance between the Countertop and the Dishwasher?

There is no definitive answer to this question since it can vary depending on the specific countertop and dishwasher model. However, a good rule of thumb is to leave around 1-2 inches of space between the two. This will ensure that there is enough clearance for the dishwasher door to open and close without hitting the countertop, and also provide enough space for any water or steam to escape from the dishwasher without damaging the countertop.

What if I Can't Measure the Size Myself?

There are a few ways to get an accurate measurement. The first is to look in your appliance manual. The second is to measure the width, depth, and height of the interior of your dishwasher with a tape measure. Finally, you can use Dishwasher’s dishwasher size calculator. Simply enter the dimensions of your dishwasher’s interior, and the calculator will do the rest!

If you’re not sure how to measure the size of your kitchen space, you can always ask a sales associate at the store for help. They will be able to tell you what size dishwasher will fit in your kitchen and also give you any other advice on choosing the perfect dishwasher for your home.

What Should I Do if I Bought the Wrong Size of a Dishwasher?

If you have purchased a dishwasher the wrong size, you have a few different options. You can either return it to the store and receive a refund or exchange it for a dishwasher that is the correct size. If you choose to keep the dishwasher, you can try to sell it online or give it away to someone who can use it. Finally, you can also try installing the dishwasher yourself and hope it fits properly. No matter what option you choose, make sure that you keep all of your receipts and documentation in case you need to reference them later on.


Dishwashers can come in many shapes and sizes. Some people might wonder, “How are dishwashers measured?” The answer to that is not surprising. When choosing a dishwasher, size is an essential factor to consider. Measure the space in your kitchen and consider the distance between the countertop and the dishwasher. 

You should also consider the dishwasher’s capacity and whether you need a portable or built-in model. Finally, remember that you may need to leave extra space around the dishwasher for easier access when loading and unloading dishes. By following these tips, you can be sure to choose a dishwasher that is the perfect size for your home. Thanks for reading!
