Enter the tile size, the area to be covered, and the waste percentage into the calculator to determine the total number of tiles needed for a tiling project. This calculator helps in estimating the number of tiles required to cover a floor, wall, or any other surface.

Tile Coverage Formula

The following formula is used to calculate the total number of tiles needed:

text{TT} = lceil frac{A times (1 + frac{W}{100})}{TS} rceil

Variables:

  • TT is the total number of tiles needed
  • A is the area to be covered (square feet)
  • W is the waste percentage (%)
  • TS is the tile size (square feet)

To calculate the total number of tiles needed, multiply the area to be covered by (1 plus the waste percentage divided by 100), then divide by the tile size and round up to the nearest whole number.

What is Tile Coverage?

Tile coverage refers to the number of tiles required to cover a specific area, taking into account the size of the tiles and any additional waste. Waste accounts for breakage, cutting, and pattern matching. It is important to estimate tile coverage accurately to ensure that enough tiles are purchased for a project, while also minimizing excess.

How to Calculate Tile Coverage?

The following steps outline how to calculate the Tile Coverage.


  1. First, determine the tile size (TS) in square feet.
  2. Next, determine the area to be covered (A) in square feet.
  3. Next, determine the waste percentage (W).
  4. Next, gather the formula from above = TT = ceil((A * (1 + W / 100)) / TS).
  5. Finally, calculate the total number of tiles needed (TT).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

tile size (TS) = 1 square foot

area to be covered (A) = 100 square feet

waste percentage (W) = 10%
