How Many 400 x 400 tiles in a square metre (m2)?

The quantity of 400 x 400 tiles in a square meter (m2) equals 7 tiles. Assuming dimensions of the tile width and height are in millimetre measurements, which equates to 40cm x 40cm tiles in a square metre.

How To calculate how many 400x400 tiles there are in a m2

To calculate how many 400x400 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: 400mm x 400mm =
0.16 m2
or 40cm x 40cm =
0.16 m2

Step 2:

Divide 1m by the area of one tile to give you the number of 400mm x 400mm tiles in a m2: 1m / 0.16 = 6.3 Tiles per m2

Step 3:

NOTE: It is only possible to buy whole tiles, therefore you need to round up 6.3 tiles to 7 tiles

6.3 tiles =
7 tiles required
