How to calculate how many tiles you need to buy

Do you need to convert feet to metres first? Use our feet to metres converter below.

  1. Firstly you need to enter the width of the tile in millimetres, for example, if the width of the tile is 150mm (6 inch), you would enter 150, enter your figure in the tile width field in the calculator below. Do the same for the tile height.
  2. Next measure the width of the area to be tiled, for example, if the width of the walls are 3 metres wide you would enter 3, enter your figure in the area width field in the calculator below. Do the same for the area to be tiled height.
  3. Finally, specify the percentage you wish to add for breakages and wastage, we would recommend adding 10%. Select your percentage for wastage / breakage in the calculator below and then hit the calculate button to find out how many tiles you will require.
