I bought 1 box just to see if I’d like it in my kitchen. I loved it! So I bought another box thinking 40 tiles would be enough for a 5 foot peninsula  it was only enough for the front of peninsula (5’length x3’height). So I had to buy another box to wrap around one side of the peninsula (2’widthx3’hieght). There was extra, so I put it on the small backsplash over the range. So make sure you buy enough especially if you’re paying someone to come out and do it. Or if you have a timeline because it takes a week to be delivered.
