Tile Calculator
Calculate exactly how many tiles you need for your project. Enter room dimensions, tile size, and waste percentage to get tile count and box requirements.
About the Tile Calculator
Buying the right amount of tile is essential for any flooring or wall project. Our calculator takes room dimensions, tile size, and waste percentage to tell you exactly how many tiles — and boxes — to purchase. For outdoor or landscaping projects requiring other materials, try our Gravel Calculator or Mulch Calculator.
Always add a waste factor to account for breakage, cuts around edges, and future repairs. A 10% waste buffer is standard for most projects. Diagonal or herringbone patterns require at least 15%. Once you know your tile count, the optional "tiles per box" field calculates exactly how many boxes to buy — always round up. If you're also replacing HVAC or an air conditioner, use our BTU Calculator to size your new unit.
