This will depend on the width the carpet you selected comes in. If your carpet style is in 15' width you need a 15 x 14 piece which is 23.33 square yards. If the carpet is in 12' widths you will need a seam. Generally installers prefer not to put more then 3 cuts in a seam. In this case you will need a 12' x 18'9" piece which is 25 square yards.

To find square feet multiply 14x14 14x14=196 sqft
There are 9 sq ft of carpet in 1 sq yd so... 33/9 = 3.67 sq yds
To calculate how many square yards of carpet you need use this formula.width X length= total square footage/9 = number of yardsSo you will need 16 square yards of carpet.
