Everything You Need to Know About Standard Dishwasher Size 2023

Many people don’t realize that the standard dishwasher actually matters. If you have a small kitchen or just need to save space, then getting the right size can be crucial.

There are so many different sizes and styles of dishwashers out there and it can be difficult to know which one suits your needs best.

Well, we’re here to help! We’ll answer all of your questions about the standard dishwasher.

standard dishwasher dimensions

Almost all standard US dishwashers out there have the dimensions of 24 inches x 22 inches x 33-34 inches. The width is generally agreed to be 24 inches, but the depth and height may vary slightly.

There are many other manufacturers that make compact or under-sink models which may be as small as 21 7/8″ x 24 3/4″ x 23 1/2″.

It is very important to know that most dishwashers are built with slightly smaller dimensions than the standard.

So they can fit properly under countertops, cabinets and worktops.

What is the standard dishwasher size for a home in America?

The standard dishwasher size in America will either be 24 inches, 27 inches, 30 inches, or 36 inches.

Most homes today use the 24 inch models, while you can find other sizes in some homes across the country.

The best thing to do is measure your cabinet size and make sure you get a dishwasher that fits it!

The first thing you need to know – a 24″ dishwasher fits a counter depth of 20″. But it won’t fit a cabinet over 22″.

Also, an undercounter dishwasher will work fine as long as you have enough room for the “swing out” door, which can be up to 10″ from side to side.

An over-the-range model has the swing outdoor on the front, which can also be up to 10″ wide.

The next issue that affects the standard dishwasher size is whether or not you have a garbage disposer. If there is no garbage disposer, then your main drain line must be 6″ in diameter, and most are 4″.

With a 4″, it’s almost impossible for water to go down the drain during the cleaning cycle if it gets too high. You will need an air gap on the sink to make sure this happens.

If there is a garbage disposal, then things change. Most home’s main drain lines are 3″, but they run at an angle. So they could actually be 2 1/2″ in some cases!

If your drain line is less than 3″, then the water may just travel down the drain during the wash cycle. You would need an air gap on your sink to make sure that doesn’t happen.

Ok, you’ve figured out if there’s garbage disposal and what size your main drain line is. Now we only have one more piece of the puzzle.

How high does your countertop or cabinetry go?

The standard height for upper cabinets (or wall cabinets) in America is 36″.

That means 24″ dishwashers will be right at counter height, 30″ dishwashers will be 1/2″ below, 27″ dishwashers will be 4″ below and 24″ dishwashers will 5 1/2″ below.

How to choose the best dishwasher size?

When buying a dishwasher it is important to buy the right size for your needs. Dishwashers come in different sizes, from 18 inches to 36 inches.

Understanding which one will work best for you will save you time and money.

What size standard dishwasher do I need?

What size of standard dishwasher do I need is the most common question we would get nowadays.

You probably feel like you’ll be overwhelmed by the many dishwasher types and sizes on the market right now and it is natural to feel that way.

However, you need a dishwasher that perfectly fits your needs and also the current layout of your kitchen.

Here we will talk about 12 things that you should ask yourself before buying a standard dishwasher to make sure you get the one that is perfect for you.

1. What features do I need?

There are some people who never use their dishwashers while others use them every day. If you only use your dishwasher occasionally then a basic model with normal cycle settings will definitely work for you.

On the other hand, if you use your dishwasher every day then consider investing in an advanced model plus stainless steel tub or third rack which offers you more flexibility. This can accommodate different loads sizes on a daily basis.

2. How many place settings?

If you’re living alone or as a couple then it is probably fine to install smaller dishwashers that hold up to 12 places setting capacity inside.

However, if you have a family of more than 4 members it is recommended to purchase dishwashers that hold up to 16 places setting capacity.

3. Size of family & lifestyle

If your family is small and there’s no one home during meal times, 21 inches standard size under counter dishwasher will definitely perfect for you.

On the other hand, if you have a large family or your lifestyle requires you to entertain often then consider buying one of the largest standard size dishwasher options which are conveniently available in 24 inches.

4. Dishwasher style

There are many different styles of dishwasher whether it is built-in dishwashers, under counter dishwashers including portable and slim models which measures typically 21 inches.

So ask yourself what type will work best for your kitchen? If you are looking for something that can blend into your existing cabinetry design then choose between built-in models.

However, these typically cost more than traditional models with better features as well as modern styling.

We also recommend you to think about standard depth dishwashers versus standard height dishwashers.

If you have enough space available for a 24 inches wide standard height model then go for that otherwise consider buying 18 inches or less storage depth to save more room.

5. What is my budget?

As always it is recommended to set the budget first. Before starting your search as different models offer different features and options at different prices.

For those on a smaller budget, there are still many great choices out there. Including some really good performing high capacity dishwasher options under $400.

6. Identify where you want to put your dishwasher

There are some houses that have a large kitchen but not enough space for the dishwasher.

Then there’s the other way around. A house with enough space but lacks of appliances.

The important thing is always to find a balance between these two considerations then only you can get the best out of your dishwasher.

Take a measuring tape and measure the width, length, and height of your current kitchen layout then by looking at the example below you will know which type of dishwasher is suitable for you.

If you feel that none of them work for you then go-ahead to the next step.

7. Which layout do I need?

The kitchen layout is another important factor to consider when buying a dishwasher.

It’s not all about the size, but also the installation dynamics and mechanics.

You might want to know how deep your cabinet or shelf is. So you can set your dishwasher on it without any problems.

Also, you need to take note if there are some cabinets blocking an area of the counter where the dishwasher is going to be placed.

8. Main purpose of your dishwasher?

This step mostly applies to people who are about to buy a dishwasher for the first time or, simply put, new homeowners.

Asking yourself what do you need from a dishwasher is essential before buying one.

Sometimes people end up buying a dishwasher that doesn’t suit their needs because they rush the decision.

For example, those homeowners who only need to clean a few dirty dishes and utensils once in a while but bought an oversized dishwasher should learn first how it works and its limitations.

Dishwashers vary in type and size and knowing what you really need will help you make a well-informed choice the next time you go shopping for one.

9. What is the size of your current dishwasher?

If you’re planning to replace an old or worn-out machine, then measure its width (front-to-back), depth (top-to-bottom) and height (top-of-counter to bottom).

If possible, try to find a similar model for comparison. This will help determine how much space is available in your kitchen and what type of new dishwasher would work best.

10. Which features are must-haves?

Determine which features you need most in your new dishwasher. Whether it’s the size of the interior, a number of wash cycles or spray arms, adjustable racks, heated drying options or simply extra compartments for cutlery.

Make sure they fit your requirements and daily use patterns before buying one.

11. How much space do you have available?

Dishwashers come in various sizes to suit different kitchens. Under counter models that mount below upper cabinetry (ideal for apartment living), countertop models that sit top counters (great for rental units with limited built-in dishwasher installation options) and full-size models designed for freestanding use (ideal for most homes).

12. What about water consumption?

This information can also help you determine which model may work best for your home. Especially if the cost of running the machine is an important factor for you when buying a dishwasher.

Energy Star qualified dishwashers are the most efficient because they use less water and energy than standard models.

For example, an average dishwasher can use between 18 to 35 gallons of water per cycle (depending on the model).

Plus, it’s good to consider how much hot or cold water is needed before buying a machine. Dishwashers that have a built-in water softener tend to use more hot water during each cycle.

The most common types of dishwashers and what do they offer?

There are several types of dishwashers, each very different from the others, as well as their combinations.

In general, they can be categorized as under-the-counter or built into a wall, semi-integrated and fully integrated.

The first is a  small dishwasher and the most common, and often found in restaurants and hotels, where he worked as a dishwasher.

It can be placed under a counter with rollers so you can push it through the kitchen easily.

A small dishwasher for a restaurant or hotel is very easy to use. Usually has just one drawer, where you load all dishes.

Controls are very simple, there is either a button Start or a knob to set the degree of cleaning desired. The dishwasher usually has wheels so you can easily push it around.

Another type of small dishwasher is built into a cabinet with doors on top. It works exactly the same way as an under-counter dishwasher.

Only the door opens downwards and it is better to use it a couple of times a day.

There are usually two discharging options: to directly into the sink, or through a drain hose.

Hands do not touch food so such a dishwasher is often used in restaurants and cafes. It’s great for washing dishes by hand or using a high-pressure washer.

The second type, semi-integrated is the most popular change for home use. It has many of the same features as a dishwasher for restaurants or hotels but it has more options and can wash a much big load.

Controls are very simple too, there is either a button Start or a knob to set the degree of cleaning desired.

It usually has wheels so you can easily push it around, or it is attached to the cabinet with a door on the front panel.

This type of dishwasher is frequently integrated with cabinetry which makes it look like it’s part of the kitchen.

The third type, fully integrated, is mostly found in high-end residences. In this type of dishwasher, the controls are hidden behind a door or panel along with one or more rows of plates, glasses and other dishes.

Dishwashers can be built into cabinetry which looks like their part of the kitchen. Or they will have an exposed handle for everyday use.

They also offer the most features and options, such as solid stainless-steel tubs with insulation or heating element.

These dishwashers usually have a triple water filtration system.

The majority of built-in dishwashers have a height of just 45 cm, so they will fit into any kitchen. They are available in all colors and finishes to suit your kitchen decor.

For people who just need a simple, inexpensive dishwashing machine for small loads, there is another type of dishwasher called a portable one.

It can be placed on the counter or mounted under it.

This little guy is very easy to use. No bells and whistles at all. No installation is required. You can move it from one place to another as you wish.

The easiest way to use it is simply standing it on the counter and attaching the faucet hose to its spout.

Portable dishwashers usually have a triple filtration system too but are much smaller in size.

So if you live alone or don’t cook very often or your kitchen is small, then this type of dishwasher will be really good for you.

But the main advantage of the portable dishwasher is that you can take it along with yourself.

When moving next time, no need to buy another machine. Just transfer this little guy into your new apartment.

You can also carry it to friends’ houses while visiting them or use it while camping out in nature.

The only thing here is that they do not work well when there is not enough water pressure.

In this case, portable dishwashers offer an extra filtration system to filter the water from food particles and dirt.

How much does it cost to buy a standard-sized dishwasher?

A standard size dishwasher is around $480 – $1100, depending on its features and options. Dishwashers with solid stainless-steel tubs and heating elements will cost more than those with plastic tubs.
