How many boxes do I need?

Question

Room is 11'X13' .Tiles are 12"X12"sq. 30ct. boxes Help!

Answer 1

You should only need 5 boxes.  11x13/30 = 4.76 boxes, so 5 will give you the extras you need.

Answer 2

You have to buy extra, most stores will sell the extras at the same cost as in full boxes. You will also find most rooms are not really square, you will need to cut the individual tiles to adjust as well as at doors.

Answer 3

A simple estimate is to take the Length x Width of your room to determine the square footage. Add 10% to 15% for waste. (10% for a straight installation, 15% for a diagonal installation or a room with intricate cuts).

My guess is you will need 6 boxes (with some leftover).
