how to measure a backstop
These three stakes represent the size of the rear panel of your backstop and should measure to 20 feet. Measure 7.5 feet in front of the left stake and place another stake in the ground at that point. Measure 12.5 feet directly left of the newest stake and place another stake in the ground. Do the same on the right side. Place a stake 7.5 feet in front of the right stake, and place another stake 12.5 feet directly to the right of this stake.
