How to Plan Tile Quantity
Convert area to tile count with allowance for cuts and breakage.
What it does and when to use it
Area alone is not enough: convert tile dimensions to meters and add waste based on layout and room complexity.
What information to enter
Enter surface area, tile width and height in centimeters, and waste percentage.
How to understand the result
The result rounds up to whole tiles. Check tiles per box before purchasing.

Formula at a glance
Tile count = area × (1 + waste) ÷ tile area
Short example
20 m² with 60×60 cm tiles and 10% waste requires 62 tiles.
Common mistakes
- Treating 60×60 centimeters as meters.
- Using too little waste for diagonal layouts or complex rooms.
