You just need to know your square footage, so length x width add 10% if laying straight 15% if in a pattern. If you want to know exactly how many pieces you need then each 18x18 contains 2.25sf. So just divide your square footage by 2.25
Tip: If your length and width are in inches then after you add your overage divide by 144.
Whatever the lxw of a single tile is ,divide that into the lxw of the room.
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
144/2.25=64. 18x18 tile cover 2.25 sq ft area.
125 square feet.
The answer depends on the measurement units used for 18x18.
160 of them.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.
2.25 square feet
Whatever the lxw of a single tile is ,divide that into the lxw of the room.
width times length 10 x 12 room needs 120 tile.
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
The diagonal of an 18x18 tile is 18*sqrt(2) = 25.46 units.
144/2.25=64. 18x18 tile cover 2.25 sq ft area.
You would need 800 tile assuming you had no waste at all. Since this is unlikely you will need 825 tile.
I want to put ceramic tile flooring in my kitchen but i don't know how to measure the footage. What is the formula for measuring square footage for ceramic tile?
You calculate the square feet of the room/ area. A square feet is still a square feet, no matter on the dimension of the tile
