What is the Tile Calculator?
The Tile Calculator is a flooring and masonry tool that determines exactly how many tiles you need to buy to cover a floor, wall, or backsplash. It prevents you from pausing a project midway due to material shortages.
How It Works (Formula)
The tool calculates the total area of the room and divides it by the total area of a single tile. It then crucially adds an industry-standard 10% to 15% "waste" factor to account for tiles that must be cut, broken, or discarded at the edges of the room.
$$ \text{Total Tiles} = \left( \frac{\text{Room Area}}{\text{Tile Area}} \right) \times 1.10 $$
The 1.10 multiplier adds a safe 10% overage for cuts and breakages.
How to Use It
Enter the length and width of the room you want to tile. Next, enter the dimensions of the tiles you are purchasing (e.g., 12x12 inches). The calculator will output the total square footage and the exact number of individual tiles you must order.
