Tile Calculator
Calculate tile count for floors and backsplash walls.
Tile Calculator
Calculate the exact number of tiles required for floors or backsplash walls based on tile size and area dimensions.
Room Area: 100 sq ft | Single Tile Area: 1 sq ft
What is the Tile Calculator and How Does It Work?
The Tile Calculator determines exactly how many tiles you need for a floor or backsplash by dividing the total area to be covered by the area of a single tile, then adding a waste allowance for cuts and breakage.
The room's area is divided by the area of one tile to get a base tile count, then increased by a waste percentage to account for cuts around edges, corners, and occasional breakage.
Tile area = (12×12)/144 = 1 sq ft; base count = 80/1 = 80 tiles; ×1.10 waste = 88 tiles needed.
Tile area = (4×4)/144 = 0.111 sq ft; base count = 25/0.111 ≈ 225; ×1.10 waste ≈ 248 tiles (rounded up).
Common Real-World Use Cases
Calculate exact tile quantities before purchasing to avoid running short mid-installation.
Determine small-format tile counts for kitchen or bathroom backsplash walls.
Generate a quick material estimate to include in a renovation quote.
- 1Enter the length and width of the area to be tiled.
- 2Enter the dimensions of a single tile in inches.
- 3Set your waste percentage for cuts and breakage.
- 4View the base tile count and the total tiles to purchase including waste.
- •Larger tiles mean fewer cuts and typically need less waste allowance than small mosaic tiles.
- •Always round up to the nearest full box, since most tile is sold by the box covering a fixed area.
