How it works
How the tile calculator works
The calculator multiplies room length by room width to get the floor area, then divides by the area of one tile. Because no room tiles perfectly, it adds a 10% allowance for cuts and breakage and rounds up to a whole number of tiles.
Tile size is the side length of a square tile in centimeters, so a 30 cm tile covers 0.3 m by 0.3 m.
Why include a 10% waste allowance
Tiles get cut to fit edges and corners, and some break during handling or installation. A standard 10% waste allowance helps ensure you buy enough and keeps spares for future repairs.
Frequently asked questions
›Does the result include extra tiles for waste?
Yes. The calculator adds a 10% allowance for cuts and breakage and rounds up to a whole number of tiles.
›What does tile size mean?
It is the side length of a square tile in centimeters. A 30 cm tile measures 30 cm by 30 cm.
›Why is the result rounded up?
You cannot buy a fraction of a tile, so the count is always rounded up to the next whole tile.
›Can I use it for walls?
Yes. Enter the wall height and width in meters in place of room dimensions.
›Should I buy more than the result?
The 10% allowance is usually enough, but keeping a few extra tiles for future repairs is a good idea.
