You will need to work out the area to be tiled. Tiling stockists will be able to help you to calculate the number of tiles you will need for your project, you can also use our handy conversion chart below.  Tiles are produced in batches, and it is important to make sure you have enough tiles from the same batch for your project, so order slightly more than you need. Any extras can be stored for future repairs.

Note: exact tile sizes can vary from manufacturer to manufacturer and some can include the joint width in their calculation of tiles/metre. Therefore the above table must only be used as a guide and is not a definitive statement of fact.
