Which Dishwasher Size is Right for Your Kitchen?

A dishwasher can truly be a lifesaver in the kitchen, making clean-up a breeze. However, finding the perfect dishwasher for your kitchen can feel overwhelming, particularly when it comes to figuring out the right size. Why is this important?

I’m glad you asked. 

I remember when I had to buy a new dishwasher for my kitchen. I assumed all dishwashers were the same size, but my excitement faded when the model I ordered turned out to be too large for my kitchen space.

Determined to find a solution, I measured the space and realized I needed a compact built-in dishwasher. With the correct measurements in hand, I searched again and found the perfect fit with all the features I initially wanted.

The experience taught me a valuable lesson: always measure your kitchen space before buying a new appliance. Now, I always remind friends and family to measure first to avoid the same mistake I made.

I created this comprehensive guide to help you navigate measuring your kitchen and pinpointing the ideal dishwasher size and style to suit your needs. From exploring standard dishwasher dimensions to learning how to measure a dishwasher, we’ll cover all the bases. So, let’s dive in!

Understanding Dishwasher Sizes and Types

Before diving into the measurement process, it’s essential to understand the different dishwasher sizes available and their corresponding types.

Standard Dishwasher Size

The standard dishwasher size is 24 inches wide, 24 inches deep, and 35 inches high. Standard dishwashers are typically 24 inches wide and are designed to fit within your cabinet opening. These built-in models are the most common dishwasher type and usually have a dishwasher capacity that can handle a larger number of dishes.

Compact Dishwasher

A compact dishwasher is 18 inches wide, making it a suitable choice for smaller kitchens or apartments where you have limited space. Like the standard dishwasher, this built-in model fits within a cabinet opening, but its smaller size means it might have less dishwasher capacity than its larger counterpart.

Countertop Dishwasher

A countertop dishwasher is a portable dishwasher that sits on top of your countertop. These dishwashers are typically smaller than standard and compact dishwashers, measuring around 22 inches wide, 17 inches deep, and 20 inches high. While they may not handle as many dishes, they’re an excellent option if you don’t have a dishwasher and want a space-saving solution that doesn’t require installation.

Oversized Built-In Dishwasher

For those with larger kitchens and a need for more dishwasher capacity, an oversized built-in dishwasher might be the right choice. These dishwashers can measure anywhere from 30 to 42 inches wide and have even more space to accommodate larger pots, pans and dishes.

Measuring the Rough Opening for Your New Dishwasher

To find the right dishwasher for your kitchen, you’ll need to measure before you shop. You’ll need the width, depth, and height of your dishwasher opening. Here are the steps to help you measure and record the dishwasher dimensions accurately.

Measure the Width

First, measure the width of the cabinet opening where you want to install your dishwasher. If you have an existing dishwasher, measure the width of the dishwasher panel or the front of your cabinets to ensure the new appliance will fit within the space.

Standard dishwasher width is typically 24 inches wide, while compact dishwashers are 18 inches wide. For oversized built-in dishwashers, widths can range from 30 to 42 inches.

Measure the Depth

Next, measure the depth of the cabinet opening to determine how deep your dishwasher can fit. To do this, measure from the back wall of the cabinet to the front of the cabinet, and record the dishwasher depth.

Keep in mind that standard dishwasher dimensions are 24 inches deep, and you’ll need to have enough space to accommodate the dishwasher door when it’s open.

Measure the Height

Finally, measure the height of your dishwasher opening, from the floor to the bottom of the countertop or the top of the opening. Most standard dishwashers are 35 inches tall, while countertop dishwashers are typically around 20 inches tall.

Be sure to account for any additional height needed for leveling legs or installation materials.

Choosing the Right Dishwasher for Your Kitchen

Now that you’ve measured your kitchen and clearly understand the different dishwasher sizes available, it’s time to choose the right one for your kitchen.

Consider Your Dishwasher Capacity Needs

When shopping for a new dishwasher, consider your dishwasher capacity needs. If you frequently host dinner parties or have a large family, a standard or oversized built-in dishwasher with more capacity might be ideal. For smaller households or those with limited space, a compact or countertop dishwasher may be a more practical choice.

Factor in Your Budget

Budget is another important point when choosing the perfect dishwasher. Standard and compact dishwashers can be budget-friendly options, whereas oversized built-in dishwashers may come with a higher price tag.

Countertop dishwashers are typically more affordable but may not offer the same capacity or features as built-in models.

Look for Features that Suit Your Needs

There is a wide variety of dishwasher types and sizes available. You can find a dishwasher with all the bells and whistles you desire, such as energy-efficient models, stainless steel interiors, or advanced washing cycles. Make sure to look for features that will make your life easier and enhance the overall dishwasher experience.

Ensuring a Proper Dishwasher Installation

Once you’ve chosen the right dishwasher for your kitchen, it’s essential to ensure that it’s properly installed. Here are some tips to make sure your dishwasher is installed correctly:

Check the Rough Opening

Before purchasing your new dishwasher, double-check the rough opening measurements to ensure it will fit within your cabinet opening. A dishwasher that still doesn’t fit in your kitchen can be a major headache, so it’s crucial to verify the dimensions before making a purchase.

Verify Required Connections

Make sure your kitchen is equipped with the connections for your dishwasher, such as a water supply line, electrical outlet, and drainage. If you’re unsure about what your dishwasher requires, consult the manufacturer’s specifications or seek professional advice.

Hire a Professional if Needed

If you’re not confident in your ability to install your dishwasher, consider hiring a professional to handle the job. A properly installed dishwasher will be completely level. This ensures optimal performance and preventing potential leaks or issues down the line.

In Conclusion

Finding the perfect dishwasher size for your kitchen doesn’t have to be a complicated process. By understanding the different dishwasher sizes and types, accurately measuring your kitchen, and considering factors like capacity, budget, and desired features, you can find the ideal dishwasher that will last for years to come.

Don’t forget to ensure a proper installation to get the most out of your new appliance and enjoy the convenience of a dishwasher in your kitchen.
