Why this calculator
Skip the spreadsheet. Give room and tile dimensions, get a clean result: surface, tile count, cut margin included.
How it works
Surface = length × width. Tile count = surface / tile size, with an overage (10% default, 15% diagonal).
Tips
- Room in meters, tiles in centimeters.
- Add 10-15% for cuts and breakage.
- Order full boxes.
FAQ
