Q:

How do you calculate the number of floor tiles you need?

A:

Quick Answer

To determine the number of floor tiles required to cover a given space, multiply the length by the width of the space in feet to calculate the total square footage or area, then divide that number by the size of the tile. This is easiest with 12-inch tiles, but it is possible for any size of tile.

Full Answer

Factor waste and mistakes into the number of tiles need to floor a particular space. Some tiles will be damaged or otherwise rendered unusable, so consider a 5 percent "cushion" to ensure accuracy.

  1. Determine the area of the space
  2. Calculate the area of a room or space by multiplying the length in feet by the width in feet. If the answer is 200, for example, then the space is 200 square feet.

  3. Divide the area by the size of the tile
  4. For 12-inch tiles, the total area is also the number of floor tiles required to cover the space. To calculate the appropriate number for other sizes of floor tiles, determine the size of that tile in square feet. For example, four 6-inch tiles make up one 12-inch tile. Therefore, divide the square footage by 0.25 to determine how many tiles will be needed.
