# How many 450 x 450 tiles in a square metre (m2)?

The quantity of 450 x 450 tiles in a square metre (m2) equals **5 tiles**. Assuming dimensions of the tile width and height are in millimetre measurements, which equates to 45cm x 45cm tiles in a square metre.

5 tiles in 1m^{2}

## How To calculate how many 450x450 tiles there are in a m2

To calculate how many 450x450 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 450mm = **0.2025** m^{2}
or
45cm x 45cm = **0.2025** m^{2}

### Step 2:

Divide 1m by the area of one tile to give you the number of 450mm x 450mm tiles in a m^{2}:
1m / 0.2025 = **4.9 Tiles per m ^{2}**

### Step 3:

**NOTE:** It is only possible to buy whole tiles, therefore you need to round up 4.9 tiles to 5 tiles

**5 tiles required**
