Use this calculator to work out the number of square meters (m2) that you will need for your project. Measure the length and breadth of each of the surfaces you wish to tile, then enter the amounts for each of the surfaces. You can input the measurements for up to four surfaces (e.g. 4 walls) to gain a total amount.
 
If you need to tile a non-rectangular room it is ofter easier to break the room into zones to determine total area as shown in this diagram.

Important : please read
This calculator should be used as a guide only. Fort a more exact figure, you should consult a professional tiler to measure the area. Although we do our best to ensure that our online tools are of a high standard, Johnson Tiles do not accept any responsibility for inaccurate results by this calculator........
Wastage
