To calculate your total square footage for a room, just multiply your room width and length together. This number however, may not tell you the amount of carpet you will need to purchase because carpet is 12 feet wide.
A 10 x 10 room is 100 square feet, but you would need to purchase 12 x 10 carpet which is 120 square feet and have 2 feet by 12 feet of waste because the room is less than 12 feet wide.
Calculate your yardage by; 120 square feet divided by 9 = 13.33 yards.
A simple 15 x 20 room would add up to 33.33 yards.
That is 15 x 20 = 300 divided by 9 = 33.33 yards.
The carpet would be 12 x 20 plus you need to fill the 3 x 20 space. Assuming this is along a wall and has little traffic you could seam 4 pieces of 5 foot lengths along that wall meaning you would have to buy a piece of carpet that would be 12x 25 or 300 square feet = 33.33 square yards.
Watch our video where our installer explains why you need to calculate for the roll width.
BUT if this is a high traffic area you may want to consider less seams and purchase more carpet
Room Yardage Chart
NOTE: You usually have to buy carpet in widths of 12 feet. If you have a room that is 10 feet by 10 feet you will have to buy a rug that is 12 feet by 10 feet. If you have a room wider than 12 feet you will need to have a seam. For example: a room 15 feet by 15 feet will require a 3 foot by 15 foot seam along one side of the room.
There will almost always be some excess carpet. This is to be expected.
Any width between 6 to 12 feet use this column
