I am trying to figure out how many square tiles I will need to complete my gym flooring. The form tiles are 20 x20. My room is 146x164.
Hey stacybrat,
Thanks for your question and welcome to the community!
Square footage is a very easy thing to calculate. To at least find out the total square footage is simply measuring width by length of the walls. Simple math is all it takes.
Since your tiles are 20 inches x 20 inches, you'll first need to remember that there are 144 square inches in a square foot.
Divide 400 square inches (20 times 20 to get that number) and divide it by 144 square inches. This will give you 2.78 square feet per tile.
I'm not sure if the number you gave me is 146 x 164 expressed in inches or feet. If it is feet, you'd get almost 24,000 square feet, which I'm gonna bet the farm and say that you meant inches...although feet is easier to calculate and what most people use for a unit of measure. This is why describing your measurements is crucial.
Assuming your room was measured in inches, this is how you calculate it.
146 inches divided by 12 (12 inches to a foot ) will give 12.17 linear feet.
164 inches divided by 12 will give you 13.67 square feet
Plug those numbers together by multiplying width times length (12.17 x 13.67) will give you 166.36 square feet for the total floor area.
Since the room is 166.36 square feet and your tiles cover 2.78 square feet, you simply divide that to get 59.8 or 60 tiles needed to successfully cover the entire room (assuming the measurements you gave were inches, not feet).
You didn't say what kind of tiles you'd be using, but since some break and you'd need to cut some, allow 10 percent waste which comes to about 66 tiles needed (59.8 tiles x 1.10 percent waste).
If you decide to use a smaller tiles, refer to the tile calculator chart below.
Let me know if you have any further questions,
