In the United States, fencing usually comes in 20 ft and 50 ft rolls, which can be joined by “unscrewing” one of the end wires and then “screwing” it back in so that it hooks both pieces. Common heights include 3 ft, 3 ft 6 in, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 10 ft, and 12 ft, though almost any height is possible. Common mesh gauges are 9, 11, and 11. 5. Mesh length can also vary based on need, with the standard diamond size being 2″. For tennis courts and ball parks, the most popular height is 10 or 12 feet, and tennis courts use a diamond size of 1. 75″ measured flat side to flat side. Tennis courts often use this smaller diamond size so that power hitters won’t be able to lodge the ball into a larger diamond size.
