How many 18" x 18" tiles would it take to cover 400 sq. ft.

Question

How many 18" x 18" tiles would it take to cover 400 sq. ft.

Answer 1

About 170-get extra for breakage

Answer 2

178 tiles

Answer 3

4 tiles = 9 sq. feet.

400/9 =44.4 rounded to 45

45X 4= 180 tiles.

Answer 4

267 (+ 10% for waste allowance)

12" x 12" tiles = 1 sq.ft            

400 sq.ft divided by 1 (sq.ft) = 400 tiles

18"  x 18" tiles = 1.5 sq.ft            

400 sq.ft divided by 1.5 = 267

Bear in mind that you will need to have a few extras in case of mistakes and to allow for cutting which is where the standard 10% extra comes into account.

I am interested to see how the 178 answer was calculated - it doesn't add up to me and we have been doing this for a long time.

Good luck.

Answer 5

Candy you will need 6 boxes of 30 tile.  I don,t think you can buy the 18  x 18 tile individually.  I would also want to have some extra down the road in case you need to replace one later.

Good Luck

Answer 6

Yes Glenn is right at 178 tiles.  But you need a few more due to cutting/wastage.
