What is the standard size for a dishwasher?

The standard size for a dishwasher across brands is 24 inches wide, 24 inches deep, and 35 inches high. Most of these are the below-the-counter type. This is the standard size across many countries, and indeed the standard size across the world. Note that most dishwashers come fitted with feet in case one needs to adjust the height.

Remember: When considering the dishwasher size to buy, you have to also consider the space size between the dishwasher and its surrounding. Keep in mind that you have to leave space, at least half an inch, all around to make it easier for the installation process. This does not apply if you want to buy the portable one.

Fortunately, many dishwasher manufacturers have considered this and included about half an inch allowance in their measurements, so that the dishwasher size against the wall, the dishwasher size against the cabinet, and the dishwasher size along the side have all been taken care of.

Frequently Asked Questions

Are there different sizes for dishwashers?

There are different sizes of dishwashers, an 18″ and a 24″ width dishwasher. So you need to choose one that fits your budget, according to your family size. For example, a family of one or two requires a smaller size while bigger families need bigger dishwasher sizes.

A compact built-in dishwasher measures 18 and 22 inches wide, 35 inches high, and 24 inches deep. It is also possible to find some measuring 22 inches wide, 21 inches high, and 20 inches deep.
A standard dishwasher measures 24 inches wide, 35 inches high and 24 inches deep, while complete-size ones are between 30 and 42 inches wide, 35 inches high, and 24 inches deep.

There are special types of dishwashers commonly known as ADA-compliant for people with special height needs. These measure 18 by 31 ¾ by 24 inches. The key issue here is height. For ADA dishwashers, the height is usually 31 ¾ inches on average.

You might also want to ask, are all dishwasher racks the same size? Well, different companies have varying dishwasher racks. When your racks start malfunctioning, or you feel you want additional features for the same, you have to measure the existing racks. This will ensure you get a perfect fit.

What size opening do you need for a dishwasher?

A standard built-in dishwasher requires an opening allowance of 49 6/8 inches high or 27 4/8 inches in front of the dishwasher. This is for the door to open easily for you to stack the dishes for cleaning, and remove them after that.

It is good to have some extra room for movement. To achieve this, measure the allotted space before you go shopping so you have a rough idea of the dishwasher size you need. This is because many of the kitchens have the space already built in, mostly between cabinets.

You want a dishwasher size that will fit into that space. Consider the dishwasher size with the door open as well.

How do I know if a dishwasher will fit?

You first need to measure the width, depth, and height of your dishwasher opening. Once you have those numbers, you can start shopping for a model that will fit.

Using tape, measure how wide, deep and high the cabinet space is. Another thing to consider here is the positioning of the handles. They should be located to the front so as not to interfere with installation, and for a good fit within the cabinet frame. As you can see it’s easy to determine the right dishwasher size before you go shopping for one.

Some dishwashers are designed to be installed under the counter, while others are freestanding. If you’re limited on space, you may want to opt for a slimline or compact model. And if you have any special requirements, like a water hookup or drainage hose, be sure to check that the model you’re considering has those features.

With a little planning, you can find the perfect fitting dishwasher for your kitchen.

How much space is needed behind a dishwasher?

Create at least ½ inch of space between the wall and the dishwasher, because the water pipe, the drainage pipe, and the power code are located behind the dishwasher at the bottom. That is for built-in dishwashers.

This is the recommended dishwasher size against the wall. The dishwasher size ensures that the dishwasher fits properly in the built-in cabinet space. Proper positioning makes your kitchen look great.

How much space should be between the cabinet and the dishwasher?

For most dishwashers, this will be around 21 inches, which applies to other base obstructions. This ensures enough room for the door to swing open without hitting the cabinets. Remember that the standard-sized dishwasher is usually 24 inches wide.

The dishwasher will also need about 3 inches of space on either side for proper airflow and water drainage. The ideal space between your dishwasher and cabinets can go up to about 30 inches.

If you have more space than this, you can still install your dishwasher, but you may need to adjust the plumbing. If you have less space than this, you may need to choose a smaller dishwasher or consider a different layout for your kitchen.

Either way, it’s important to ensure that you have enough space for your dishwasher to operate properly.

How much space should be between the countertop and the dishwasher?

It is advisable to leave a space of about ½ inch to allow for air circulation. Otherwise, there is no need for a dishwasher size above the counter. If your dishwasher manufacturer has not indicated that you need a gap, you do not have to consider it.

In case you wonder whether you can further economize on kitchen space, note it is almost impossible to find a dishwasher size above the sink. From the research done, there are no such dishwashers.

Conclusion

To recap, there are variations in dishwasher sizes across brands. There is also a standard dishwasher size across the world. Additionally, there is a standard dishwasher size that measures 24 by 24 by 35 inches. As you do your shopping, you need to consider that a dishwasher size with an open door and one that is built-in requires 49 6/8 inches in height and 27 4/8 inches at the front of the cabinet.

This is to allow the dishwasher to open and close with ease.

You should leave ½ inch of space between the wall and your dishwasher. This is because most built-in dishwashers have the water pipe, the drain pipe, and power codes at the back.

To ensure that your dishwasher fits well, evaluate the space size it will occupy before you make your purchase to avoid disappointment. Getting the right dishwasher size gives your kitchen a neat look.

So there you go, all the best as you shop for a dishwasher. Feel free to ask any questions or concerns in the comments area.
