What Are the Standard Kitchen Countertop Measurements?

Here are our tips so you can be confident you’ll have accurate kitchen countertop measurements for your renovation.

Standard Countertop Height Measurements

The standard height measurement for countertops is 36 inches from the floor. It’s considered to be the best ergonomic height at which most tasks can be done in a kitchen for a user of average height (between 5 feet and 3 to 5 inches). 

Standard Countertop Width Measurements

The average kitchen countertop measures 25.5 inches wide (going from the wall to the counter’s edge). Some measure up to 28 inches, but you usually won’t find any wider than that. Standard measurements allow for a 1.5-inch overhang over 24-inch deep base cabinets.

Standard Kitchen Island Countertop Measurements

When upgrading your kitchen island, note that the standard measurement is between 25 and 25.5 inches. Some island bases can support countertops up to 48 inches if you desire more workspace. 

Standard Countertop Thickness Measurements

There are three standard sizes for countertop thickness measurements – 1, 2, and 3 centimeters. Typically, three centimeters is the preferred thickness for most countertops for most fabricators, designers, and architects since it offers the most durability, size flexibility, and color options.

Reasons To Go Against the Standard Kitchen Countertop Measurements

Who says you always have to follow the rule book? If you want to change the height of your countertop or opt for an extra-large island — go for it! There are plenty of reasons why you can go against the standard kitchen countertop measurements. 

Reason #1: Adjust to Your Ergonomics

Yes, the standard height for kitchen counters is 36 inches, but what if you’re taller or shorter than the average person? Customize your countertops to save you from spending hours in an uncomfortable position that can cause damage to your body. 

Reason #2: Accessibility

One of the most common reasons people deviate from the standard counter height is to account for those with special physical needs. In fact, many designers navigate accessibility for commercial applications by having a dedicated surface shorter than the standard counter.

If you’re designing a space that needs particular accessibility, note that 34-inch tall countertops will suit most wheelchair users. You can also go taller than the average height if accommodating an exceptionally tall individual. 

Reason #3: Bar Height

While 36 inches is the height of the average countertop, 42 inches is the standard bar height. Some homeowners opt to have their counters at this higher level, doubling as a home bar or quaint dining area. It’s also a good way to keep valuables out of the reach of children. 

How to Measure Kitchen Countertops

To accurately measure the square footage of your countertops, you’ll need the following materials:

• Tape measure
• Pen
• Paper
• Calculator

Next, follow the steps below, and you’ll have accurate measurements for your new countertops in no time.

Step 1:

Sketch an approximate diagram of the existing countertop surface area (and island and backsplash, if applicable). Don’t forget to include the placement of the sink and appliances. 

On your drawing, separate the counter into rectangle sections. You’ll measure each of these independently. 

Note: Treat a rounded or oval island as a square. 

Step 2:

Measure and take note of all lengths of the countertop sections.

Step 3:

Measure and take note of all widths of the countertop sections.

Step 4:

Multiply each section’s width by its length to get the square footage. Mark it in each section of your drawing so you can keep track. 

Step 5:

Add up all the separate sections to get the total area in square inches. Suppliers often quote the price in square feet, so you’ll have to convert the area to the correct units. Divide the area in square inches by 144 to get the area in square feet.
