How To Measure For Countertops
Hey, this is Todd Bauer with Builder Surplus. I’m going to take a quick moment to help you learn how to calculate square footage requirements for Granite and Quartz countertops.
I have a small kitchen layout here that I have drawn in and it kind of represents a typical L-shaped kitchen with an island.
I am going to walk you through quickly how to calculate out the number of square feet you’re going to need.
I’ve already done a little bit of pre-work here. In this particular layout, we have an L-shaped kitchen with a sink on this wall. Here a stove, an island and there’s your refrigerator.
There is going to be basically four calculations that we need to do in order to calculate your square footage. Let’s just dive right into it!
First of all, the length from the corner in this particular corner to the end of your current countertop you need to measure that. In my example, I have 120”. Countertops (by design) are roughly 25.5” deep so I’ve marked that here.
For the corner here, after we turned the corner and head down I want you to measure from the corner to where, in this case, the stove would begin, and I get a measurement in my diagram of 66”.
Stoves traditionally are 30” across. Yours should probably that way as well. In my example, this last piece is 48” wide.
My island currently is 36” deep by 60” long and that’s pretty standard for a small basic island.
Now the math. The first thing we’re going to do is calculate the number of square feet on the left leg of this L. If I take 120” and I multiply it by 25.5”, I’m going to calculate the number of square feet for this piece of the Land that’s perfect.
In my example over here, 120” x 25.5” = 3060 sq. inches. I am going to take you through the calculation to get square inches and then at the end we’re going to turn it into square feet.
For the second piece of the L, if you remember at the beginning, I noted that from the corner to the stove we have 66”. Now we’ve already taken 25.5” of that and we’ve accommodated for it on the left leg so we’re going to need to reduce the 66” by 25.5” and that’s going to get us to 40.5”. If we take our 40.5” which is the new distance from here to the stove and we multiply that by our 25.5”, we’re going to get 1032.75 square inches.
Piece C on the other side of the stove is 48” x 25.5” and that gets us 1224 square inches and then lastly, the island 60” x 36” multiply those two together to get us to 2160 square inches.
These numbers are large but they are going to get small really quick here.
Once you have your 4 pieces calculated I’d like you to just add them up and in my example, the total is 7476.75 square inches. Divide that by the number of square inches in one square foot and that’s 144”. You just take 12” x 12” to get 144” by dividing your total square inches by the square inches in one foot. You are going to get the number of square feet and in this example, we have 51.9 square feet.
That’s the number you need to bring with you when you come to Builder Surplus to get a calculation on how much it’s going to cost to replace your countertops.
The only other things I am going to have you note would be any cutouts. A cutout in this particular example is right here where I have a sink and that’s it for this particular one.
You may have a cooktop cut out but in my example, I have a stove so there is no cut. The only other thing that might be handy to bring with you would be if your island has an overhang where the granite or the quartz extend beyond the edge of the cabinets and how far is the overhang so that we can pretty much do the calculation here.
If your countertop island depth is 36” we’re calculating the overhang to be about 12” but just double-check and make sure and with that a little bit of information it’s that easy with the math that I’ve shown you today.
Maybe with a quick diagram and a calculator you’ll be able to come up with the number of square feet that you need for your countertops!
