The size of the yard to be sodded is determined by measuring length and width. Multiply the length and width to find the square feet. Then the square feet are divided by 9 (9 square feet to 1 yard) to find the square yards, which is how sod is sold.
Sod costs per square foot as of 2009 were 14 to 60 cents for a contractor to install it.
