From there the basic formula to calculate the number of tiles required to cover an area is to divide the size of the area by the area of a single tile.
How to calculate tiles base needed for a floor.
Number of tiles area size single tile area this is however an idealized situation.
It can also account for the gap or overlap between tiles.
So if the wall or floor measures 5m long by 4m wide multiply 5 by 4 and your calculation will be 20 square metres.
148 1 7 41 tiles.
For the wall measure the height of the wall up to down and width of the wall from right to left.
Number of tiles required 156 tiles approx wastage rendered wastage damaged tiles.
How to calculate tiles needed for a floor.
Do this for each wall or floor area you need tiled and then add all of the numbers together.
13 33 m2 0 09 m2 5.
For the floor measure the length of one side of the room and then measure the width of another side of the room.
Finally the total number of tiles required for the above room is number of tiles required total area to be laid area of one tile wastage.
Multiply the length and width measurements you obtained which will give you the total square meterage of the wall and or floor areas.
Add an important part of the calculation the size of the gap you want between the tiles.
