What Are the Dimensions of a Standard Dishwasher?
When planning a kitchen remodel or replacing an old appliance, understanding the dimensions of a standard dishwasher is essential for a seamless fit and optimal functionality. Dishwashers come in various sizes, but the term “standard” refers to the most common measurements designed to fit typical kitchen layouts. This article dives deep into the dimensions of a standard dishwasher, explores variations, provides measurement tips, and offers additional insights to help you choose the right one for your space.

Defining the Standard Dishwasher Size
The standard dishwasher size is widely recognized across the industry as approximately 24 inches wide, 24 inches deep, and 35 inches tall. These dimensions are tailored to fit snugly into most modern kitchen cabinet openings, which are typically built to accommodate this size. However, there¡¯s a slight nuance: the actual dishwasher might be a fraction smaller¡ªoften around 23.5 to 23.75 inches wide¡ªto ensure easy installation with a bit of wiggle room.
According to KitchenAid, “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 Standard Dishwasher Sizes ))]. This consistency makes it easier for homeowners to replace an existing unit without needing to modify cabinetry.
Whirlpool echoes this, noting, “A dishwasher labeled as 24 inches wide might actually be more like 23-1/2 inches wide. Most cabinet openings are made to fit a standard dishwasher size.” They also highlight that “certain handles may affect the overall dishwasher depth,” which is a critical detail when measuring your space.

Why Standard Dimensions Matter
The uniformity of standard dishwasher sizes stems from both practicality and design standards. Builders and manufacturers align these dimensions with typical kitchen layouts and the Americans with Disabilities Act (ADA) guidelines, ensuring accessibility. As Angi explains, “The second reason dishwashers are almost always [these sizes] is that they need to be ADA-compliant. These standards are put in place to ensure a building is physically accessible to people with disabilities” [(( Angi Dishwasher Sizes ))].
This standardization simplifies the buying process. Whether you¡¯re upgrading an appliance or designing a new kitchen, you can rely on these dimensions as a baseline, though slight variations exist depending on the brand or model (e.g., handle protrusion or adjustable legs).

Breaking Down the Dimensions
Let¡¯s explore each dimension in detail:
Width: 24 Inches (Typically 23.5¨C23.75 Inches)
- Why it varies: The listed 24-inch width refers to the cabinet opening, not the dishwasher itself. Manufacturers make the appliance slightly narrower to slide into place effortlessly.
- Key consideration: JennAir notes, “This is the standard width that most dishwashers are available in and the size that most kitchen layouts can accommodate.” Wider options (30¨C42 inches) exist for oversized models, but these are less common.
Depth: 24 Inches (Excluding Handles)
- Details: Measured from the back to the front, excluding the door handle. Bar handles can add 1¨C3 inches, so Maytag advises, “Dishwasher depths are usually listed with the depth of the door included, which will make the complete depth slightly larger than the opening depth.”
- Installation tip: Ensure at least 27 inches of clearance in front for the door to open fully, as recommended by Whirlpool.
Height: 35 Inches (Adjustable to 33.5¨C36 Inches)
- Flexibility: Most dishwashers come with adjustable legs to fit under countertops ranging from 33.5 to 36 inches high. This accounts for flooring differences or counter height variations.
- Note: Maytag warns, “Kitchen flooring may not have been installed under the dishwasher and could add more height to your opening,” so check your space carefully.

Variations Beyond the Standard Size
While 24 x 24 x 35 inches is the benchmark, dishwashers come in other sizes to suit diverse needs:
- Compact (18-Inch Wide): Ideal for small apartments or kitchens, these are typically 18 inches wide, 24 inches deep, and 35 inches tall. They hold fewer place settings (6¨C8 vs. 10¨C14 for standard models).
- Oversized (30¨C42 Inches Wide): Designed for larger households, these maintain standard depth and height but offer greater width and capacity.
- Portable: Often 24 inches wide, 27 inches deep, and 37 inches tall, these standalone units don¡¯t require cabinet installation.
- Countertop: Compact at 22 inches wide, 20 inches deep, and 17 inches high, perfect for renters or tiny spaces.
This Old House sums it up: “While 24 inches wide, 24 inches deep, and 35 inches high are the standard dimensions, dishwashers can be larger or smaller. Always check the dimensions carefully before buying” [(( This Old House Dishwasher Sizes ))].

How to Measure for a Standard Dishwasher
Accurate measurements are crucial to avoid an ill-fitting unit. Bob Vila provides a clear guide: “Being familiar with the type of unit you need and verifying the measurements for your available space will save you the hassle of returning a dishwasher that doesn¡¯t fit in your kitchen.” Here¡¯s how to do it:
1. Width: Measure the opening between cabinets at the top and bottom. Use the smaller number if they differ. Add 2 inches if installing next to a wall or cabinet for door clearance.
2. Depth: Measure from the back wall to the front of the cabinet. Account for handle protrusion and ensure 27 inches of space in front for the door.
3. Height: Measure from the floor to the countertop¡¯s underside at the left, middle, and right. Adjustable legs can compensate for slight variations.
The Home Depot adds, “The height of the space can vary depending on whether the room is level. To get an accurate measure of the cabinet opening height for your new dishwasher, take three measurements” [(( Home Depot Measuring Guide ))].

Additional Considerations
Interior Capacity
Exterior dimensions don¡¯t always reflect interior space. A standard 24-inch dishwasher typically holds 10¨C14 place settings, but features like a third rack or adjustable tines can maximize capacity. Maytag explains, “The interior dishwasher design can limit or maximize capacity even among dishwashers of the same size.”
Handle Impact
Handles can extend depth. Pocket handles align flush with cabinets, while bar handles protrude, affecting aesthetics and space requirements.
Installation Space
Leave room for plumbing and electrical connections. Whirlpool advises, “Utility placement can vary by model, so check your installation instructions for the specifics.”

Choosing the Right Dishwasher
Selecting a dishwasher involves more than just size. Consider:
- Household size: A standard 24-inch model suits families of 3¨C5, while compact units work for 1¨C2 people.
- Kitchen layout: Ensure the door can open fully without hitting counters or islands.
- Features: Look for energy efficiency (Energy Star certification), noise levels (below 44 dBA for quiet operation), and rack flexibility.
Samsung¡¯s buying guide suggests, “Measure the width, height and depth of the available space, and compare this against the model you¡¯re looking at” to ensure a perfect fit [(( Samsung Dishwasher Guide ))].
