How sod quantity is estimated
Sod is usually sold by the piece, roll, or pallet. Mini rolls and larger rolls cover different amounts of turf, so the calculator divides the lawn area by the selected piece coverage to estimate how many units you need.
A waste allowance of 5 to 10 percent is added to cover cutting losses around curves, edges, walkways, and garden beds. Irregularly shaped lawns should use the higher end of the waste range so you do not come up short during installation.
