The opening for a dishwasher should be at least 24 inches wide and 34 inches high. The opening should also be level so that the dishwasher can be installed properly. If the opening is not level, the dishwasher may not operate correctly and could cause leaks.

Dishwashers come in all shapes and sizes, so it’s important to know what size opening you need for your dishwasher. The average dishwasher has a width of 24 inches, but the height and depth can vary. Most dishwashers are about 35 inches tall and have a depth of about 25 inches.

However, there are some compact dishwashers that are only 30 inches tall and have a depth of 20 inches. If you’re not sure what size dishwasher you need, ask a salesperson at your local appliance store for help.

Dishwasher Standard Size Inches

If you’re in the market for a new dishwasher, one of the first things you’ll need to consider is size. Most dishwashers are standard size, but there are also compact and built-in models. Standard dishwashers are typically 24 inches wide, which is the industry standard.

However, some models may be as narrow as 22 inches or as wide as 26 inches. When it comes to depth, most dishwashers range from about 17 to 24 inches deep. The average height of a dishwasher is about 35 inches tall, but some models can be as short as 32 inches or as tall as 38 inches.

If you have a particularly small kitchen, you might want to opt for a compact model that’s about 18 inches wide and 28 inches deep. Built-in dishwashers are designed to fit flush with your cabinets so they’re completely hidden when not in use. Now that you know the basics of size, it’s time to start shopping!

Keep in mind that dimensions can vary slightly from manufacturer to manufacturer, so be sure to double check the specs before making your purchase.

How Big of an Opening Do You Need for a Dishwasher?

If you’re considering a dishwasher for your home, one of the first questions you’ll need to answer is: how big of an opening do you need for a dishwasher? The size of the opening required will depend on the model and make of the dishwasher. Most dishwashers are about 24 inches wide, but some models can be as wide as 36 inches.

As far as height goes, most dishwashers are about 34 inches tall. However, there are models that are only 30 inches tall or less, which can be a good option if you’re short on space. Depth-wise, most dishwashers require about 24 to 25 inches of depth clearance.

When measuring for your new dishwasher, be sure to take into account any other appliances that might be in the way. For example, if your sink is located directly next to your stovetop, you might not have enough room for a full-sized dishwasher. In this case, a compact or slimline model would be a better option.

Keep in mind that even though most Dishwashers come in standard sizes, there are always going to be slight variations from one model to another. So when in doubt, always consult with the manufacturer’s specifications before making your final decision.

What Size Gap for Dishwasher?

If you’re looking to install a dishwasher in your kitchen, one of the first things you need to do is determine what size gap you have for the appliance. The average dishwasher is about 24 inches wide, so you’ll need at least that much space between cabinets or appliances on either side. However, it’s always best to err on the side of caution and give yourself a few extra inches of space if possible.

That way, you won’t have to worry about the appliance being too tight in its spot and potentially causing problems down the road.

How Big is the Opening for a 24 Inch Dishwasher?

A 24-inch dishwasher typically has a tub opening that is about 21 inches wide and 18 inches deep. The size of the opening will vary slightly from model to model, so it is best to consult your owner’s manual or the manufacturer’s website for specific dimensions. Most 24-inch dishwashers can accommodate up to 12 place settings, so they are a good option for families or households with moderate dishwashing needs.

If you have a larger household or do a lot of entertaining, you may want to consider a larger-capacity dishwasher.

Are All Dishwashers 24 Inches Wide?

No, not all dishwashers are 24 inches wide. Some dishwashers are as small as 18 inches wide, while others can be up to 36 inches wide. The size of the dishwasher will depend on the model and make of the appliance.


When it comes to dishwashers, size does matter. The average dishwasher is about 24 inches wide, but the opening for your dishwasher should be about two inches wider than that. This will give you enough room to load and unload your dishes without having to worry about them fitting through the door.
