Tiling quantity question

A tiling quantity question.



Went to Leek Tile Centre and ordered 2 square metres of tiles. We received 160, maybe 162 four-and-one-eighth-inch tiles. Queried this with Leek Tile Centre and they tell us that 162 tiles is 2 square metres.



I'm having difficulties working this out (I'm coming up with nearer



180). Could someone tell me where I'm going wrong?

With 5mm grout spacing it's about 2 sq. m.

Crikey, you're right

One side of a tile is 0.104447m Four sides of a tile is 0.417788m Four sides of 160 tiles is 66.84608m

66.84608m x 0.005m =3D 0.3342304 sq m taken up by grout ie about 30 tiles!

Thanks

Each tile (assuming 3mm grout line) will be 108mm x 108mm = 11664 square mm

1 square metre = 1,000,000 square mm 1,000,000 divided by 11664 = 85.7 tiles per sq metre = 171 tiles total

Using a 5mm grout line the answer would be 165 tiles

Working backwards to get 162 tiles to 'exactly' cover 2 sq metres you would need a 6mm grout line.

See other answers but did you include extra to allow breakages when laying plus any future breakages .It doesn't sound like you did :-)

Er...We've just ordered 60 more tiles to allow for just that. And for the tiler tiling a wall we didn't want him to...
