What to buy

  • Tiles 30 × 60 cm

    8 boxes — 64 tiles

    2 spare after wastage

Add your prices in the cost section of the form. We never guess prices — a made-up figure is worse than none.

How to work out how many tiles you need

  1. Measure the length and width of the area you are tiling and multiply them for the area.
  2. Multiply the tile width by the tile height for the area of one tile.
  3. Divide the area by the tile area to get the number of tiles.
  4. Add wastage — 10% for a straight lay, more for diagonal or patterned work.
  5. 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.
