How to work out how many tiles you need
- Measure the length and width of the area you are tiling and multiply them for the area.
- Multiply the tile width by the tile height for the area of one tile.
- Divide the area by the tile area to get the number of tiles.
- Add wastage — 10% for a straight lay, more for diagonal or patterned work.
- Divide by the tiles per box and round up. Boxes are what you actually buy.
The tile formula
Area = length × width
Tile area = tile width × tile height
Tiles = area ÷ tile area
Tiles with wastage = tiles × (1 + wastage %)
Boxes = tiles with wastage ÷ tiles per box, rounded up
Example: a 4 × 2.5 m floor in 30 × 60 cm tiles
The floor is 10 m² and each tile covers 0.18 m², so you need 55.6 tiles — 56 rounded up. With 10% wastage that is 62 tiles. At 8 tiles a box you buy 8 boxes, which is 64 tiles and leaves 2 spare.
