Finding the perfect dishwasher size for you requires careful measuring, decoding capacities, and choosing the features you’ll use the most. This guide will help you find a dishwasher to fit both your kitchen and your culinary pursuits.

WHAT SIZE DISHWASHER DO I NEED?

Most home dishwasher dimensions fit a cabinet opening of around 24 inches wide, 24 inches deep and 35 inches tall. This is considered a standard dishwasher size and many home kitchens today are built with this size in mind. 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 on KitchenAid.com, 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.


HOW TO MEASURE THE CABINET OPENING FOR A DISHWASHER

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 this easy dishwasher measuring guide 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.

Width of a dishwasher cutout

1. MEASURING DISHWASHER WIDTH

  • 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.

Height of a dishwasher cutout

2. MEASURING DISHWASHER HEIGHT

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

  • 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. MEASURING DISHWASHER DEPTH

  • 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 Dishwasher with custom panels, the overall depth may vary depending on the panel.

When planning your kitchen, keep in mind that handles, towel bars and dishwasher control placement may affect the overall dimensions and space your new dishwasher will occupy. While these features won’t affect the rough opening requirements, they will change the way you interact with your new appliance. Front control dishwashers keep settings and cycles within view, at your fingertips and flush with the dishwasher door. Fully integrated dishwashers, or top control dishwashers, keep controls hidden away for an extra sleek look. Dishwashers with handles can add a premium touch to your kitchen design but if your dishwasher is installed in a high-traffic area, dishwashers with pocket handles help reduce the overall dimensions.

WHAT CAPACITY SIZE DISHWASHER DO I NEED?

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. 

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 1 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

INCREASE DISHWASHER FLEXIBILITY WITH A THIRD RACK

Innovations such as dishwashers with a third rack give you extra rack space up top. Third racks can range from slim spaces for kitchen utensils to ones that fit dishes such as cups or bowls. The KitchenAid® 39 dBA Dishwasher in PrintShield™ Finish with a Third Level Utensil Rack holds silverware, serving utensils and spatulas while an adjustable middle rack adds flexibility to fit tall items. KitchenAid® FreeFlex™ Rack Dishwashers feature the largest third rack available1 with a deep, angled design that fits 6" glasses, mugs and bowls.

MORE DISHWASHER FEATURES THAT 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. The KitchenAid® 44 dBA Dishwasher with Panel-Ready Design features fold down rows and tines in the lower rack. They can be adjusted in one of three positions so water can clean inside deep or wide dishes.  An adjustable middle rack on the KitchenAid® 44 dBA Dishwasher in PrintShield™ Finish with FreeFlex™ Third Rack adds flexibility to fit tall items like a stand mixer bowl. Lower the rack to place large dishes inside or raise it to make room for platters, pitchers, blender jars and more in the rack below. Adjustable or specialized features such as these increase the kind of loading flexibility the creative cook is looking for.
