Quandaries and Queries
 

 

I am putting up backsplash tile in my kitchen and I need to know how many tiles I would need to use for about 45 square feet using 4x4 tiles.
 
Thank you

Hi Jeannette,

The tiles are 4 inches on a side and there are 12 inches in a foot, so it takes 3 tiles to give a foot length and hence 3 × 3 = 9 tiles to make a square foot.

You need to cover 45 square feet so you need 9  45 = 405 tiles.

This calculation does not take wastage into account. The exact number will depend on the shape of the backsplash as well as the square footage.
