kitchen sink sizes

If you’ve decided you want to replace your old kitchen sink with a new one, it can be difficult choosing your new sink. Not only do you have to consider the new style and type of sink you want, but you have to know the exact kitchen sink size you want.

Kitchen sink sizes can vary. Inevitably, the number of bowls, or basins, a sink has is dependent on sink size. For instance, the more bowls a sink has, the larger the sink size will be. Yet, with so many different kitchen sink sizes, it can be difficult to know which one is right for you.

In this article, you’ll learn all about kitchen sink sizes. From all the common kitchen sink sizes available, to how to measure a sink, you’ll have all the information you need to pick the right size sink for your renovation project.

Standard Kitchen Sink Size

There are a wide variety of kitchen sink size options to choose from. This can be both a blessing and a curse if you are trying to decide what new kitchen sink to install.

That being said, the standard kitchen sink size is about 22 inches long by 30 inches wide.

However, the size of the sink is impacted by the number of sink bowls and the overall purpose of the sink. For example, many kitchen sinks can range from 24 inches to 36 inches wide.

Most standard, single-bowl kitchen sinks can be up to 30 inches. Nonetheless, if you want an even larger sink that spans wider than 30 inches, you’ll likely have to choose from a series of double or triple bowl sinks (though there are still wide, single bowl sinks).

There are also kitchen sinks that span 36 inches wide. These types of sinks are called oversized sinks and they can be often found in professional kitchens where a large sink would be needed.

Now that you know about the standard length and width of kitchen sinks, you cannot forget about the depth of your kitchen sink. The average depth of a sink can range from about 7 to 10 inches deep.

Standard Size Of Double Kitchen Sink

A standard double bowl kitchen sink is inevitably going to be larger than a standard-size single bowl kitchen sink. The standard size of a double kitchen sink is anywhere from about 33 to 36 inches wide.

The extra room with the double bowl allows for ease of washing dishes by hand and is especially good if you have a large family.

Are All Double Sinks The Same?

No, all double sinks are not the same. Although both sinks can each be a double bowl sink, they can have different dimensions. For instance, one double sink can be 33 inches wide whereas another can be 36 inches wide.

Most double sinks are 50/50, meaning each basin is the same size. However, there are different sink bowl ratio sizes like 60/40 and 70/30 where one basin will be larger than the second bowl, which is another thing to consider.

Likewise, the depth of the sinks can differ. One double sink can be only 7 inches deep, while another double bowl sink could be 10 inches deep. Neither sink option is better or worse, it just comes down to personal preference and if your family is willing to sacrifice countertop space for more room to clean all your dishes.

Standard Size Of Farmhouse Kitchen Sink

The standard size of a farmhouse kitchen sink is 30 inches, 33 inches, or 36 inches long. Similar to a single bowl and double bowl kitchen sink, there is still a variety of farmhouse sink sizes which is great to ensure you can get the right sink size for your home.

Different Types Of Kitchen Sink Sizes

As discussed above, there are a variety of kitchen sink sizes, mainly based on the need for a particular type of sink. For instance, a large family that washes dishes by hand may find a double bowl sink better whereas a standard single bowl sink is still a normal, average sink found in many homes.

Therefore, inevitably the bowl size and desired use out of the kitchen sink impact the size of the sink. You may not want a large sink because you lose countertop space.

Below is everything you need to know about different common kitchen sink sizes.

24 Inch Kitchen Sink

With a 24-inch kitchen sink, this is on the low end of the standard kitchen sink size. However, don’t let this size fool you.

A 24-inch kitchen sink can be big enough. It mainly depends on your needs and what you expect to get out of your sink. If you especially have a small kitchen, a 22 or 24-inch kitchen sink size could be good for the lack of space. This is because the sink is big enough to rinse a dish or wash your hands, without taking up too much precious counter space.

Therefore, if you have a smaller kitchen space, a 24-inch sink is an excellent option.

36 Inch Kitchen Sink

On the flip side, a 36-inch kitchen sink is on the high end of the kitchen sink size spectrum. A 36-inch kitchen sink is definitely too big for a small kitchen space. Likewise, a 36-inch kitchen sink is not just too big, but rather unnecessary for a typical family home.

Often, 36-inch sinks, called oversized sinks, are any sink that measures 36 inches or wider. These sinks are optimal for large kitchens or professional kitchens where a wide sink would be needed to place and clean all your dishes!

30 Inch Kitchen Sink

A 30-inch kitchen sink size is the standard kitchen sink size.  Although a 30-inch sink would be too large for a small kitchen, most average family-sized homes commonly have about a 30-inch sink.

This sink size is great because it’s just big enough to have enough room to wash your hands and clean dishes. However, it’s not too big that it’s taking up too much countertop space.

33 Inch Kitchen Sink

Another common sink size is the 33-inch kitchen sink. If you are interested in a 33-inch sink, it’s most likely a double bowl sink. This can be great if you have a large family, especially one that washes dishes by hand.

Therefore, don’t let this larger sink-size option deter you. If your family has the space and needs a larger sink for all your dishwashing and cleaning needs, consider a 33-inch kitchen sink. It’s big without being overly large like an oversized sink.

60/40 Kitchen Sink

A 60/40 kitchen sink, or an offset sink, is a double bowl kitchen sink that has one bowl/basin that is slightly larger than the other, thus the term “60/40”.

This type of double bowl kitchen sink style can be helpful for those looking for a slightly bigger bowl to fit larger pots and pans to clean. Although double bowl kitchen sinks are often wider than single bowl sinks, this doesn’t take into account that the width is split into two different bowls.

Therefore, if you have a larger pot, you may need the extra space of an offset sink to clean it over a traditional double bowl sink style.

Smallest Kitchen Sink Size

Typically, the smallest kitchen sink size is about 22 inches wide. This small size sink is great for smaller kitchens that need a sink, but don’t want a large sink that will take up too much of the counter.

Largest Kitchen Sink Size

Meanwhile, the largest kitchen sink size is about 36 inches for a large home. Often referred to as an oversized sink, these large sinks are typically found in extremely large kitchens or professional kitchen settings.

However, double bowl kitchen sinks can be as wide as 46 inches. And, triple bowl sinks can be as large as 60 inches wide!

How Deep Is A Normal Kitchen Sink

Most kitchen sinks are about 7 to 10 inches deep. Depending on your personal lifestyle needs will impact whether you want a deeper sink or not. For instance, if you tend to stack and pile dishes in your sink, consider getting a deeper sink.

Therefore, if you are looking for a deep sink to soak and clean lots of dishes, consider a 10-inch sink which is a great size to hold and clean all your dishes.

How To Measure A Kitchen Sink

Now that you have an idea of all the different kitchen sink sizes available, it’s time to know how to measure for a new sink.

First, you’ll want to figure out what type of kitchen sink you have. There are three main types of kitchen sink types:


  • Undermount Sinks- Sink that is installed below your counter.


  • Drop-In Sinks- Sinks that are installed on top of the countertop along the edge.


  • Farmhouse Sinks- Sinks that have an exposed front and deep sink bowl.


Once you’ve figured out your kitchen sink type, you're going to simply measure the dimensions of the sink: length, width, and depth. Depending on the type of kitchen sink will influence how you measure.


  • Drop-in sink: Measure exactly as you would from edge to edge of the sink’s end. This is because the drop-in (or top-mount) sink sits exactly on the outline of the counter.


  • Undermount sink: Measure from the edge of the counter opening to the other edge of the counter opening.


  • When measuring the depth of your sink, be sure you are placing your measuring tape at the deepest part of the sink and up to the top of the sink.


  • When measuring the length of your sink, place the tape from the left to right edge of the sink and write down the sink length.


  • When measuring the width of your sink, place the tape from the top (side of the sink faucet) down to the edge closest to you and write down the width of the sink.


Next, you’ll want to measure your cabinet space. This is to ensure when installing your new sink that the sink width and depth are the same as the old sink. Otherwise, you may need to replace your cabinet if you are looking to get a completely different size sink.

To measure your cabinet, measure the depth by placing your ruler from the bottom cabinet edge and measuring from front to back of the cabinet. Then, for the width, measure from the left edge to the right edge of the sink.

To get the overall sink width needed, subtract 4 inches from the width cabinet measurement and 1 inch from the depth cabinet measurement.

Frequently Asked Questions

sink questions

What side is the garbage disposal on a 60/40 sink?

You can put the garbage disposal on either side of your 60/40 sink. However, typically the garbage disposal is placed on the larger bowl side because food from dishes is often scrapped off on the bigger bowl side, making it easy to then use the garbage disposal on that larger bowl side.

Can an undermount sink rest on a cabinet?

No, an undermount sink cannot just simply rest on a cabinet alone. You should have your undermount sink held in place by using a series of clips and caulking to attach it under your countertop.

What size sink goes in a 36 cabinet?

Choosing the right sink size for your exact cabinet size can be tricky. For a 36-inch cabinet, you’ll want a sink that’s width is less than the interior of your cabinet with a little extra space. Therefore, a 36-inch cabinet typically has a 33-inch kitchen sink.

Can you put a 30 inch sink in a 36 inch cabinet?

Yes, if you have a 36 inch cabinet, your cabinet should be able to fit and accommodate a kitchen sink anywhere between 30 inches to 33 inches.

Will a 30 inch sink fit in a 30 inch cabinet?

No, a 30 inch sink will not fit in a 30 inch cabinet. This is because your cabinet needs to have a bit of extra room to be able to fit the sink. For instance, a 36 inch cabinet space can fit a 30 to 33-inch kitchen copper sink. Therefore, if your sink and cabinet are the same sizes, they will not fit together.
