This is a common question and ultimately this depends on the size of the tile. A 150 x 150mm will give you approximately 44 tiles to a square metre, but a 600 x 600mm tile will give you 2.8 tiles per square metre.
We have created a table giving you the most popular tile sizes and how many tiles you will get to the square metre (approx. only).
