Why Trust Us

If your old dishwasher has been chugging along and wearing out over time, you might be excited by the prospect of a new unit. Modern dishwashers come with exciting features like WiFi connectivity and various cycles that are made for different types of cookware. However, before you can look at different dishwasher options (or even pick the color you want) you need to understand the various dishwasher sizes.

There are standard dishwasher dimensions and then there are unique models that break these rules. By measuring your space, you can determine what size dishwasher you need. Here’s how you can figure out the dimensions for a dishwasher and a few top models to choose from.

How to Measure Dishwasher Dimensions in Inches

Even the most dedicated home cooks won’t build their kitchen around the dishwasher. This is an essential tool for cleaning up, but it’s rarely the centerpiece of the room. Instead, dishwashers are usually installed near the sink where they can hook up to the water and drain lines. Most builders will create a space using standard dishwasher dimensions.

Look at your existing space and measure the width, height, and depth where your dishwasher will go. You don’t need to save space between the wall and the dishwasher, as the electric plug won’t take up much space. Additionally, many drain lines run through the cabinet under the sink, so they also don’t take up room behind the dishwasher.

You will notice that many dishwashers are slightly smaller than the spaces you save for them. For example, if you have 24-inches of width, the dishwasher will actually be 23.75 inches wide. This ensures the unit will fit in the space.

Once you have a clear idea of your dishwasher size needs, you can choose the perfect dishwasher for you. Here are a few top recommendations to consider.

Dishwasher Type Dishwasher Dimensions
Built-In 24" Dishwasher 24 W x 24 D x 35 H
Built-In 18" Dishwasher 18 W x 24 D x 35 H
ADA Compliant Dishwasher 24 W x 24 D x 32 H
Drawer Dishwasher 23 W x 23 D x 16 H
Portable Dishwasher 24 W x 25 D x 36 H

Frigidaire also offers an 18-inch dishwasher model if you need to install this appliance in a smaller space. Stop handwashing dishes because you think your kitchen is too small. If you have an 18-inch cabinet near your sink, you have space for a dishwasher. This smaller unit can still keep up with the needs of your family. It can hold up to eight place settings in one cycle, with room for cups, plates, and utensils.

When you run your dishwasher, you can decide which cycle is appropriate based on what needs to be cleaned. There are multiple cycle options including Energy Saver, Heavy Wash, and Rinse Only. There is also a 24-hour delay start so you can program your dishwasher for the future. Finally, this dishwasher is certified by the National Sanitation Foundation® because it removes 99.9% of household bacteria through the course of a cleaning cycle.

You can buy this model in black, white, or stainless steel. Check out customer reviews to learn more about this dishwasher. One buyer says, “I was worried about the smaller size unit but the efficiency and operation of this appliance is remarkable! I just got out of Basic Training and bought my first house. Being single I didn't need a full-size unit and this definitely is doing the job!”

Best ADA-Compliant Dishwasher

Samsung 24" Stainless Steel Built-In Dishwasher

24 W x 24 D x 32 H

There are several factors that determine whether a dishwasher is ADA-compliant. The dishwasher needs to be easy to load and unload, with doors that don’t block kitchen walkways. However, one of the main factors for ADA compliance is height. Instead of following standard dishwasher dimensions, ADA-compliant models will be slightly shorter to accommodate the lower countertops made for people who use wheelchairs. This unit can meet ADA height guidelines or rise up to meet the standard dishwasher size.

This dishwasher by Samsung comes with adjustable racks that can be set at different height levels. This is ideal for homeowners that need to clean different types of cookware depending on the meals they prepare. Sometimes we need to wash several place settings after a family dinner, while other times you need space to wash a crockpot or wok. 

This Samsung dishwasher also comes with features like a delay start system and four different wash cycles to choose from.

Best Drawer Dishwasher

23 W x 23 D x 16 H

Dishwasher manufacturers continue to rethink how Americans clean their cookware. Dishwasher drawers are becoming increasingly popular for customers who have small spaces. These can meet standard dishwasher dimensions in houses that have existing space for these appliances or they can fit into smaller areas that have water and drainage hookups.

This is a smaller dishwasher that is easy to open, close, and load. It comes with the same cycles and washing options that you would expect from any full-size mode. You can run the dishwasher on a normal cycle or opt for the Rinse, Fast, Delicate, Eco, or Heavy options. This drawer can handle both your delicate crystal glasses and your heavy pots and pans.

This model is ADA compliant and runs a quiet cycle. When operating on a gentle cycle, this dishwasher is only 45dBA. Read customer reviews if you want to learn more and potentially add this dishwasher to your home.

Best Portable Dishwasher

GE® 24" Stainless Steel Portable Dishwasher

24 W x 25 D x 36 H

Most dishwashers are designed to be installed near your kitchen sink between your cabinets. They hook up to the water line and remain in place until they break. However, portable dishwashers are meant to hook up to your sink and can be wheeled in and out of the kitchen when they need to be used. A portable dishwasher is ideal for homeowners who have closet space but don’t have room in their kitchens for this appliance.

You don’t have to be as focused on dishwasher dimensions when purchasing these units because the appliances are freestanding in your kitchen. Instead, you can review the features to make sure you are purchasing the best possible model. In this GE dishwasher, the stainless steel blade rotates at 3,600 RPM which breaks up food particles and washes them away. This prevents your filter from getting clogged and keeps food bits off of your cookware.

You can learn more about this particular portable dishwasher by reading customer reviews. One buyer writes, “I really do not like washing dishes by hand and I live in a house with no dishwasher. I purchased this portable unit and I couldn't be happier!”


Do dishwashers have a standard size?

You can find dishwasher models in a variety of sizes; however, the standard dishwasher dimensions are 24 inches wide by 24 inches deep by 35 inches tall. This will be the dishwasher size for most homes.
