Dishwasher Size in Feet: Standard Dimensions Explained (2026)

Dishwasher size in feet describes how big a standard dishwasher is. A common unit is about 2 feet wide. It is about 2 feet deep. It stands nearly 3 feet tall. This is the standard built-in size.

Have you ever bought a dishwasher that didn’t fit the gap? The cabinet cutout is the key. A standard unit slides under the counter. A compact model fits tight spaces. Once you measure, the choice gets simple.

The standard width is 24 inches. Compact models are 18 inches wide. The unit fits just under a 36-inch counter. You need 4 feet of clearance in front. These facts make dishwasher size in feet easy to picture.

Dishwasher Size in Feet in Different Units

A standard built-in dishwasher is a boxy appliance. It measures about 2 feet (24 inches) wide, 2 feet (24 inches) deep, and 2.9 to 3 feet (34 to 35 inches) tall. In metric, that’s roughly 61 by 61 by 89 cm. Here’s how the dishwasher size breaks down.

Measurement	Feet	Inches	Centimeters
Width (standard)	~2 ft	24 in	~61 cm
Depth	~2 ft	24 in	~61 cm
Height	~2.9–3 ft	34–35 in	~86–89 cm
Width (compact)	~1.5 ft	18 in	~46 cm
Depth with door open	~4 ft	~49 in	~124 cm
Cutout width	~2 ft	24 in	~61 cm

These are standard built-in sizes, so treat them as close approximates. The 24-inch width is the most common. Compact 18-inch models suit small kitchens. Always measure your cabinet opening before buying, since a tight fit matters.

10 Everyday Comparisons for a Dishwasher’s Size

Here are 10 ways to picture the dishwasher size in feet using objects and spaces you already know. Each one is close to a key measurement.

The 24-Inch Width (Two Feet)

The standard width is 24 inches (2 feet), close to two rulers laid side by side. This is the most common dishwasher width, made to fit a standard cabinet gap. Picture two rulers end to end to see the width.

The 24-inch width is the industry standard for built-in dishwashers, matching the cabinet opening in most kitchens. Compact models are narrower at 18 inches. Because a ruler is exactly 12 inches, two of them show you the width easily. If you picture a 2-foot gap in your cabinets, that’s where a standard dishwasher slides in. It’s the key number to check when replacing or planning a dishwasher, since the cabinet cutout must match.

The Height (About 3 Feet)

The height is about 34 to 35 inches (nearly 3 feet), so the dishwasher fits just under a 36-inch counter. Picture a counter with the dishwasher sliding into the gap below. It reaches almost to the countertop.

Built-in dishwashers are sized to tuck under a standard 36-inch counter, leaving a bit of room for adjustment. The height is often adjustable by an inch or two using leveling legs. Because a kitchen counter is a familiar height, it’s an easy reference. If you look at the space under your counter, that’s where the dishwasher fits. The unit’s 3-foot height slides neatly into this gap in an under-counter setup.

The Depth (Two Feet)

The depth is about 24 inches (2 feet), close to two rulers laid front to back. This is the distance from the front of the dishwasher to the back wall. The door adds more depth when open.

The 24-inch depth matches standard base cabinets, so the dishwasher sits flush with the counter edge. The front panel lines up with the cabinet faces for a built-in look. Because two rulers make 24 inches, that’s an easy way to picture the depth. If you measure 2 feet back from the cabinet front, that’s how deep the dishwasher reaches. It’s a standard depth that fits most kitchen layouts without sticking out.

The Door-Open Depth (About 4 Feet)

With the door open, the depth reaches about 49 inches (4 feet), close to one arm span. This is the space you need in front of the dishwasher to load and unload it. Picture your arm span reaching out from the unit.

The open door drops down and adds about 25 inches to the depth. You need clear floor space in front so the door can open fully and you can reach the racks. This matters in small kitchens, where an island or wall might be close. Because an arm span is easy to picture, stretch your arms to gauge the space. If you have about that much room in front, the dishwasher door opens comfortably.

The Compact Width (1.5 Feet)

A compact dishwasher is 18 inches (1.5 feet) wide, close to a ruler and a half. These narrow models suit small kitchens, apartments, and homes with fewer dishes. Picture a ruler plus half another to see the width.

The 18-inch compact size holds fewer place settings than a standard 24-inch model, but fits tighter spaces. It’s a good choice when cabinet room is limited. Because a ruler is 12 inches, one and a half rulers show the width. If your cabinet gap is only about 18 inches, a compact dishwasher is the fit. It’s the narrower option for kitchens where a full-size 2-foot unit won’t work.

A Kitchen Counter (Fit Reference)

A kitchen counter is the key height to compare. A standard counter is 36 inches (3 feet) tall, and the dishwasher is about 34 to 35 inches, so it fits just under with a little room. Picture the dishwasher sliding into the under-counter gap.

Counters are built to a standard 36-inch height, and dishwashers are sized to fit below them. This is the main measurement for a built-in fit. The small gap lets you level the unit and connect the plumbing. Because a counter is in every kitchen, it’s the easiest way to picture the fit. If your counter is a standard height, a standard dishwasher will tuck underneath it neatly, as they’re designed to match.

A Microwave (Width Comparison)

A microwave helps you picture the dishwasher’s width. A standard countertop microwave is about 20 to 24 inches wide, close to the dishwasher’s 24-inch width. Set a microwave next to the gap to compare.

Microwaves come in sizes, with larger ones close to 2 feet wide. Their width is near a standard dishwasher’s. Because a microwave is a familiar appliance, it makes a good comparison. A dishwasher is about as wide as a large microwave. If you have one on your counter, picture its width to gauge the dishwasher’s 24-inch size. It’s an easy kitchen reference for the width using an appliance you likely already own.

A Two-Year-Old Child (Height Cue)

A toddler helps you picture the dishwasher’s height. The average two-year-old stands about 34 inches tall, close to the dishwasher’s 34-to-35-inch height. Stand a young child next to the unit to compare.

Kids grow at different rates, so heights vary at this age. Growth charts track this range as normal for two-year-olds. Because a toddler is a familiar height, it makes a fun comparison. A dishwasher is about as tall as a typical two-year-old. If you know a child this age, picturing them next to the appliance helps you gauge its height. It’s a relatable way to imagine the 3-foot height using a familiar human size.

A Base Cabinet (Fit Reference)

A base cabinet shows the dishwasher’s cutout size. A standard base cabinet gap for a dishwasher is 24 inches wide, 24 inches deep, and 34.5 inches tall, matching the appliance. Picture the empty cabinet slot where it fits.

The cutout is built to standard dimensions so any 24-inch dishwasher slides in. The width and height must match closely for a snug, built-in fit. Because cabinets follow these standards, most dishwashers are interchangeable. If you’re replacing an old unit, the cutout is already the right size. Measuring this gap first is the key step before buying, since the new dishwasher must match the cabinet opening in an under-counter install.

An Oven (Size Comparison)

A wall oven or range helps you picture the dishwasher’s size. A standard range is 30 inches wide, a bit wider than the dishwasher’s 24 inches. Both are boxy kitchen appliances of similar height. Set them side by side to compare.

Ranges and dishwashers are both built to fit standard kitchen layouts, with the range a bit wider. Their heights are similar, sized to line up with counters. Because an oven is a familiar appliance, it makes a good comparison. A dishwasher is a bit narrower than a standard range. If you picture your oven’s width, the dishwasher is about 6 inches less. It’s an easy kitchen reference for the size using another common appliance.

How to Measure for a Dishwasher Without a Pro

No installer on hand? These simple steps help you check if a dishwasher fits using a basic tape measure.

Measure the Cabinet Cutout

Start with the opening. Measure the width, height, and depth of the cabinet gap where the dishwasher will go. A standard cutout is about 24 inches wide, 34.5 inches tall, and 24 inches deep. Write down all three numbers. The dishwasher must be slightly smaller than the opening to slide in. This is the most important step, since even an inch off can mean the unit won’t fit. Measure twice to be sure.

Check the Door Clearance

Door clearance matters for loading. Measure the floor space in front of the dishwasher spot. You need about 49 inches, or 4 feet, from the back wall so the door can open fully. Stand where the dishwasher will go and stretch your arm out to gauge the space. If a wall, island, or cabinet is closer than that, the door may not open all the way, making it hard to load dishes.

Use Rulers for a Quick Check

Rulers give a fast size check. Since a standard dishwasher is 24 inches wide, lay two 12-inch rulers end to end across the cabinet gap. If they fit with a little room, the width works. Do the same for the depth. For the height, two rulers stacked reach 24 inches, so add a bit more to reach the 34-inch height. This quick trick helps you estimate the fit with no tape measure.

Dishwasher Size vs. Other Kitchen Appliances

Seeing the dishwasher next to other appliances builds a clear picture. A standard dishwasher is 24 inches wide. A compact dishwasher is narrower at 18 inches. A standard range is wider at 30 inches. And a standard refrigerator is much bigger, around 36 inches wide. So the dishwasher is one of the narrower built-in appliances, sharing its 24-inch width with many base cabinets.

Appliance	Typical Width	Compared to a Dishwasher
Compact dishwasher	18 in	Narrower
Standard dishwasher	24 in	The base width
Wall oven	24–30 in	Similar to wider
Range/stove	30 in	Wider
Refrigerator	36 in	Much wider
