WHAT IS THE STANDARD DISHWASHER SIZE?

The standard dishwasher size is typically 24 inches wide, 24 inches deep and 35 inches tall. Cabinet openings in many home kitchens today are built to fit this standard dishwasher size.

KitchenAid offers a wide selection of standard-sized dishwashers with a range of load capacities and features designed to help you fit the dishes you use the most.

Many retailers list dishwasher dimensions by the cabinet opening needed for installation. For example, a dishwasher that is 23-½ inches wide may be listed as a 24-inch dishwasher because that is the size opening it requires. When shopping for a KitchenAid® dishwasher, you can find the specific dishwasher dimensions in the product details section. Make sure to check the product dimensions against your available space before purchasing a new dishwasher.

 

3 STEPS TO MEASURE STANDARD DISHWASHER DIMENSIONS

Once installed, built-in dishwashers must be completely enclosed on all sides including the top. While you will want to choose a dishwasher size that most closely fits your cabinet opening, a unit that is too snug may not slide in all the way. It’s better to have a little extra space that can be covered with additional trim if needed. Follow these standard dishwasher dimensions instructions to get started finding the right size dishwasher for your kitchen.


TIP:

Utility connections vary by dishwasher model so make note of the connection location within your cabinet opening to plan ahead when shopping for a new dishwasher.

1. MEASURE STANDARD DISHWASHER WIDTH Opening

  • Measure the distance between the cabinets in your rough opening. 

  • To ensure accuracy, first measure near the top of the opening, and again near the bottom. If there is any difference, always go with the smaller of the two measurements.

2. MEASURE STANDARD DISHWASHER HEIGHT Opening

  • Measure the distance between the floor and the lowest point of your countertop. 

  • Even if the underside of the countertop appears even, take two measurements to account for any minor sloping that could affect clearance. First, measure near the back of the opening and then measure again near the front.

  • Most dishwashers have adjustable feet to add a little height where needed and to level the unit. 
    Note: Always measure an empty opening rather than trying to estimate this distance with an existing dishwasher in place. If new flooring has ever been placed in your kitchen, it may not have been installed underneath the dishwasher. This means the floor under your dishwasher could be lower than the rest of your kitchen.

3. MEASURE STANDARD DISHWASHER DEPTH Opening

  • Measure the distance from the back of the dishwasher opening to the front edge of your cabinets. 

  • It’s best to measure along the sides of each cabinet to account for any variations between them.

  • Keep the dishwasher door clearance in mind when deciding where to install your dishwasher or what size dishwasher to buy. You’ll want the ability to fully open your dishwasher door and slide out the racks while still freely moving around your kitchen as you create and clean. A minimum of 27 inches beyond your cabinets is usually required. 
    Note: If you are buying a KitchenAid® dishwasher with custom panels, the overall depth may vary depending on the panel.

When planning your kitchen, keep features such as protruding handles and dishwasher control placement in mind for your new dishwasher. While these features won’t affect the rough opening requirements, they will change the way you interact with your new appliance. KitchenAid® front control dishwashers keep settings and cycles within view and flush with the dishwasher door. Fully integrated dishwashers, or top control dishwashers, keep controls hidden away for an extra sleek look. KitchenAid® dishwashers with handles can add a convenient space to hang towels, but if your dishwasher is installed in a high-traffic area, dishwashers with pocket handles help keep the exterior flush with cabinets.

Are Dishwashers All Standard Size?

The vast majority of dishwashers are standard sized and fit typical kitchen cabinet openings. If you’re in the market for a new dishwasher, this is most likely what you need. However, there are smaller and larger dishwasher sizes available for non-standard spaces.

 

What Are Other Dishwasher Sizes?

Alternatives to standard-sized dishwashers include oversized dishwashers that often feature increased capacity and small dishwashers that will fit a more compact living space. If you are a renter and can’t install an appliance, you may even consider a portable dishwasher you can take with you.

1. OVERSIZED DISHWASHER DIMENSIONS

Oversized dishwasher dimensions usually run anywhere from 30 inches to 42 inches wide. Their depths and heights are often consistent with those of standard-sized dishwashers, which are 24 inches deep and 35 inches high.

2. APARTMENT OR SMALL SPACE DISHWASHER DIMENSIONS

Compact dishwashers usually run from 17 5/8 inches to 18 inches wide, and share the height and depth dimensions, 24 inches deep and 35 inches high, of standard-sized dishwashers.

3. PORTABLE DISHWASHER DIMENSIONS

Unlike their built-in counterparts, portable dishwashers are freestanding and can glide around the kitchen on four wheels. These dishwashers attach to the kitchen sink faucet when in use. Dimensions vary greatly, ranging from 18 to 24 inches wide, 36 to 37 inches tall and 26 to 30 inches deep.

What is Dishwasher Capacity?

Dishwasher capacity is measured by how many place settings the model can hold with most standard-sized dishwashers handling between 10 and 12 place settings. The Association of Home Appliance Manufacturers considers one place setting to include the following:

Large dinner plate Small snack plate Saucer
Bowl Coffee cup Drinking glass
Knife 2 Teaspoons Dinner fork + Salad fork

Dishwasher dimensions and dishwasher capacity are not the same thing. Larger dimensions do not necessarily mean you can fit more dishes inside. This is because every dishwasher interior is designed differently including the number of racks, the placement of tines and the available features that can help handle more dishes within the same dimensions. Once you’ve determined which dishwasher dimensions will fit your space, consider capacity and available features to find a dishwasher made for the way you create.

WHAT IS A THIRD RACK DISHWASHER?

Innovations such as KitchenAid® dishwashers with a third rack give you extra rack space up top.

WHAT DISHWASHER FEATURES CAN OPTIMIZE CAPACITY?

Beyond load-size capacity, shopping by dishwasher features can help you find a model that feels customized to you. If you often use larger or uniquely shaped dishware like tagines, woks, and blender jars, look for interior features that can comfortably accommodate them. Adjustable or specialized features like the ones below increase the kind of loading flexibility the creative cook is looking for.
