Building a 8-Foot Fence
For a 8-foot fence, use 12-foot 6×6 posts set about 42 inches deep, spaced every 6 feet, with 4 horizontal rails per section and about 3 bags of 60 lb concrete per post. A 100-foot run works out to 20 posts (including one gate), 60 bags of concrete, 68 rails, and about 320 pickets if you use standard 3.5-inch boards.
Codes and permits: An 8-foot residential fence almost always needs a permit, and many zones only allow it along rear lot lines or with a variance.
