How to Measure Countertops When You Have a Unique Layout


Correct countertop measurements are critical to your new installation. In fact, when you first visit our showroom, we can only give you the most accurate estimation if you can provide the right measurements for your space.


Simple layouts are easy to measure, but some kitchens are complex. We’re going to break down exactly how you can measure your countertops accurately when you have a unique design.


After you finish measuring your unique kitchen, next you need to determine how you can create a focal point with the new stone. We can share a few ideas with you in our newest guide. 


How Do You Measure A Countertop?

There are three rules here. 

  1. Measure multiple times to be certain you’re correct.
  2. Never round down your estimates.
  3. Take the longest edge for both the length and the width, multiply them together and divide by 144 to get your square footage.

Wait, that’s a lot to digest. So, how about some examples to show you what we are talking about.


Let's start with something easy. Sometimes, you have a rectangular countertop with nothing complicated to consider. 


Measure the length and the width of the space, and multiply those numbers together. Take that new total and divide that by 144.  In our example of a countertop that is 72-inches by 30-inches, we wind up with a 15 square-foot countertop. Simple as that.

Let's crank up the uniqueness a little. Let's say your countertop bows out a little. It can be rounded or angular. 


Either way, it's as simple as the rectangular countertop. Measure the length, and then measure the width at its widest. If it bows out, measure it from the back to the farthest point that sticks out. Do the math as you would for a rectangular countertop and voila!

Now we’re getting to the harder layouts. What if you have an L-shaped countertop?


This one is going to come in two slabs, with an invisible seam between them.


Label these sections “A” and “B.” Go ahead and measure the total length of the back of the countertop, in this case; it is 103-inches. However, 28 of those inches belong to slab “B,” so subtract 28 from 103, and you get 75 inches.


Always measure multiple times, and compare that number with a measurement of the front of the countertop. If you have a square kitchen, then things should add up perfectly. 


Now, the width of slab “A” is 28-inches, so multiply 75 by 28, and then divide by 144 to get 14.59 square feet.


Slab “B” is going to get a similar treatment as a regular rectangular countertop. Length, times width, divide by 144. We got 9.73 square feet in our example. 


Add the two square footage totals, and you get just under 24.32 square feet in total, but it's safer to go ahead and round up here.

Let’s consider a layout where slab “B” is at an angle. Measure Slab “A” like you would a normal countertop. This time when measuring Slab “B”, measure the longest side.  Otherwise, it's the same process as the L-shaped countertop.

Okay, now what if the elbow has an angle?


What if your countertop has a really unique angle to it? Surely, it would be impossible for anyone but the experts to measure correctly, right?


If you have been following along, you are an expert in countertop layout measurement. 


This one is just as simple as the one above, only this time. You measure slab “A” and slab “B” by their longest points. 


Measuring your countertops


Now you’re ready to measure just about any kitchen layout. Do the countertops have several ledges? Does your kitchen have an Island?  Does your layout have several outcroppings and angles? 


For you, it should be no problem. Using the methods above, you should be able to tackle any space in your home. 


Just be careful: if your friends and family find out that you know how to measure your countertops accurately, they may be calling you to come to measure theirs. 


The stone you choose doesn’t have to only be for a simple countertop renovation. You can use the stone to create a stunning focal point in your home.
