Frequently Asked Questions

How many tiles do I need?

Calculate the number of tiles by dividing the floor or wall area by the area of one tile, then round up and add waste allowance. Measure the space in metres (length × width = m²), convert tile size to m² (tile length × width), divide room area by tile area, then add 5–10% for straight runs or 10–15% for diagonals, patterned layouts or irregular rooms. Always buy whole tiles and keep extras for repairs.

How many 60x60cm tiles are in a square meter?

There are about 2.78 60x60cm tiles in one square metre. Each tile measures 0.6m by 0.6m, which is 0.36m², so 1 ÷ 0.36 ≈ 2.78. In practice you cannot buy a fraction of a tile, so you would need 3 whole tiles to cover 1m², and it is sensible to order extra for cuts and breakages, typically 5–10% more for walls and 10–15% for floors depending on the layout.

How many tiles for a 12x12 room?

If your room is 12ft by 12ft and you use 12in x 12in tiles, you will need 144 tiles, plus allowance for cuts and waste. A 12ft x 12ft room is 144 sq ft and a 12in tile covers 1 sq ft, so add around 10% for cuts and breakage, giving about 158 tiles to order. If you plan on a different tile size, use the tiling calculator to get an accurate figure.
