Dishwasher Sizes & Dimensions

Like most high-end appliances, many professional-style dishwasher sizes are available to you. Discover the different sizes below, from larger dishwashers to ones made for specific types of cookware. Learn more about compact, standard and larger capacity dishwasher options and find the best fit for your kitchen.


Dishwashers vary in size depending on the model. While 24 inches wide is considered the standard size for a built-in dishwasher, there can be variations in the heights and depths of dishwasher models as well as different size appliances all together.


​​While there are many different dishwasher sizes, the majority of dishwashers will often come in standard sizes. This is due to the area builders and developers allot for cabinetry and countertops, as well as doorways and entryways for bringing the appliance into your home when installing your dishwasher.

Here are the most common dishwasher widths you’ll find:


This is the standard width that most dishwashers are available in and the size that most kitchen layouts can accommodate. This dishwasher size is designed to fit comfortably within most kitchen cabinets for a seamless, integrated look. 

18 Inches Wide, or Compact Size

Dishwashers are also available in a compact size, which is typically 18 inches wide. Compact dishwashers can provide smaller kitchens with limited space the ability to have a dishwasher, however this is not the standard size for most dishwashers.

30-42 Inches Wide, or High Capacity

Larger, high capacity dishwashers are also available in 30-42 inch wide options for kitchens with more space. Dishwashers of this size are more likely to be used in homes with a more spacious kitchen layout and used to accommodate larger families.

In luxury kitchens, many opt for having two or more dishwashers to increase their dishwashing capacity and allow for washing items simultaneously while entertaining or hosting dinner parties.

Whether you’re remodeling or upgrading your current appliances, measuring is always a good place to begin as you shop for your new appliance. Learn more about how to measure the width, height and depth of your space to find the perfect new dishwasher for your kitchen.

1. Measure Dishwasher Width

Start by measuring your existing appliance and available space in your home. While you may think it is a good idea to buy the same size appliance that you already have, it is essential to account for additional widths like handles or trim kits during professional dishwasher installation.

To measure the dishwasher opening width, simply measure the distance between the cabinets in your rough opening at home. Make sure to measure both the top and the bottom of the opening to get an accurate measurement.

Measuring doorways or entryways is also an excellent place to check before purchasing a professional dishwasher. The dishwasher will have to be installed in your home and enter through one of these access points.

2. Measure Dishwasher Height

To measure the height of the dishwasher, you should measure the distance between the floor and the lowest point of your countertop. Make sure to measure near both the back and the front of the opening to ensure accurate measurements. 

3. Measure Dishwasher Depth

To measure the depth of the dishwasher, you will need to measure the distance from the back of the dishwasher opening to the front edge of your kitchen cabinets. You should also keep in mind the dishwasher door clearance when deciding where to place your dishwasher or what size to purchase.

High-End Dishwasher Capacity

When measuring the capacity of a dishwasher, it refers to the amount of dishes your appliance can hold. A professional dishwasher will allow more dishware and sizes to fit in the various racks. High-end dishwashers will sometimes allow you to hold more place settings than standard models, with some options holding up to 14 full place settings.

Of course, a dishwasher load will not always be the same. Professional-style models are designed with flexible features to help you make the most of your dishwasher’s available capacity. Raise or lower your racks to accommodate things like tall pans or long glasses. Certain rows of tines can be lowered to make room for wide bowls, while cup clips help let you load glassware easily. These features are designed to help you include more in each cycle and reduce the number of dishes left in the sink.

What Size Dishwasher Do I Need?

The dishwasher size that’s right for you depends on your personal preferences, kitchen configuration and the specific size of the opening your kitchen has for dishwasher installation. You should also consider how frequently you will be accessing the appliance and how much space you need in your kitchen overall.

Most dishwashers are available in the standard 24-inch size which fits in most kitchen layouts and are also available in both smaller and larger capacities based on your personal needs.
