How To calculate how many 450x900 tiles there are in a m2

To calculate how many 450x900 tiles there are in 1 square metre, use this method:

Step 1:

Multiply the width and height of one tile. So in this case the area of one tile is: 450mm x 900mm =
0.405 m2
or 45cm x 90cm =
0.405 m2

Step 2:

Divide 1m by the area of one tile to give you the number of 450mm x 900mm tiles in a m2: 1m / 0.405 = 2.5 Tiles per m2

Step 3:

NOTE: It is only possible to buy whole tiles, therefore you need to round up 2.5 tiles to 3 tiles

2.5 tiles =
3 tiles required
