About this tool
The calculator converts your tile size from centimetres to square metres, divides the floor area by the area of one tile, then adds your waste percentage for cuts around edges and the odd breakage. The final figure is rounded up, since you cannot buy part of a tile.
Frequently asked questions
What waste percentage should I use?
10 percent is a common allowance for a straightforward room. Use 15 percent or more for diagonal layouts or rooms with many corners and cuts.
Are the tiles assumed to be square?
No. You enter length and width separately, so rectangular tiles work just as well.
