Question: how do you calculate how much carpet you need for a room?
Answer: To calculate your total square footage for a room, just multiply your room width and length together. Use a decimal when needed. That is 12' width x 10' length = 120 square feet divided by 9 = 13.33 yards. In this case, there would be 2 feet x 10 feet of carpet waste because the room is less than 12 feet wide.
