The kitchen is one of the most important rooms in your home, but no kitchen is complete without a reliable, easy-to-use sink.
In this article, you’ll learn all about the dimensions of kitchen sinks to help you with your next purchase.
Before heading to the store, you’ll need to know the sink’s length and width. To get the correct sizes, measure your countertop and under-cabinet and subtract three from those dimensions.
I used to work in the plumbing department at Menards, so I know a thing or two about sinks. I’ll teach you all you need to know about kitchen sink dimensions.
Standard Kitchen Sink Dimensions

Food service businesses must have a sink with three compartments that each measure at least 18 x 18 x 12 inches.
However, the standard household kitchen sink usually has one to two compartments. A residential kitchen sink is typically no more than 36 inches long.
After 36 inches, the sink is considered oversized. The most common length for a sink is between 30 and 33 inches.
Most experts suggest you buy a sink that’s at least 7 inches deep, but some sinks have a depth of up to 10 inches. The average width of a standard kitchen sink is about 22 inches.
Although there are standard sizes for kitchen sinks, the size of your sink will depend on how large your kitchen is and what the dimensions of your countertop and under-cabinet are.
Determining the correct kitchen sink dimensions is essential, and not just for aesthetic reasons. A sink that’s too short can cause pain in your neck, back, or shoulders when you use it often.
Sinks that are too large take up too much space, making the kitchen uncomfortable at best and unusable at worst. On the other hand, sinks that are too small might leak and lead to water damage.
You’ll save time, money, and your back when you calculate the correct kitchen sink dimensions.
Other Options

A newbie will think that if you’ve seen one sink, you’ve seen them all. But we know better!
There are countless styles, materials, and sizes to choose from when it comes to kitchen sinks.
From copper and stainless steel to natural stone and fireclay, kitchen sinks now come in many robust materials to match your kitchen decor. Once you choose a material you like, it’s time to select a style.
Some popular ones include:
- Apron Front: Apron front sinks are also called farmhouse sinks. With a bowl depth of anywhere from 8 to 9 inches, these sinks have deeper bowls than many other options.
- Drop-In: These sinks work well with any counter dimensions, small or large. They’re also the easiest sinks to install.
- Prep Sinks: Prep sinks are best for larger kitchens because you install them in addition to the normal kitchen sink. They usually have a single bowl that’s much smaller than traditional kitchen sinks.
- Wall-mounted: The wall-mounted sink has a unique vintage appeal. These sinks typically have one bowl that is smaller than more modern kitchen sinks.
- Corner Sinks: Corner sinks are perfect for making the most out of a small kitchen space. Installing a corner sink is a little trickier, as you need to get the precise dimensions of two separate countertops. These sinks are about the same size as a modern kitchen sink, with two bowls about 7 inches deep.
Finally, choose the size of your sink by determining the kitchen sink measurements. Make sure you also consider the size of your kitchen.
Things to Consider

You know what size sink you need, and you found a style you love. You’re all ready to install the perfect kitchen sink, right? Wrong! There are a few more things to consider before you buy.
Drain Location
The drains in most sinks are centered, but some prefer to have the drain further to one side or towards the back of the basin.
Whatever you decide, you need to make sure that the plumbing in your kitchen will work with the sink’s drain location.
Drainboards
Drainboards are a feature that many people overlook. If you hand wash a lot of dishes, an inbuilt drainboard serves as the perfect drying rack.
Number of Bowls
Kitchen sinks usually come with one to three bowls. How many bowls you choose depends primarily on how you will use the sink.
You should opt for a sink with two or three bowls if you hand-wash dishes or cook often.
Size of Your Kitchen
That 36-inch granite sink might be the sink of your dreams, but it might be overkill in your 60-square-foot kitchen.
Choose a sink that adds to your kitchen’s decor but doesn’t overwhelm it.
Dishes
Do you hand wash your dishes, or do you mainly use a dishwasher?
If you mostly wash your dishes by hand, you should opt for a deeper sink. Choose one that’s anywhere from 8 to 10 inches deep.
