Building a 4-Foot Fence
For a 4-foot fence, use 6-foot 4×4 posts set about 24 inches deep, spaced every 8 feet, with 2 horizontal rails per section and about 2 bags of 60 lb concrete per post. A 100-foot run works out to 16 posts (including one gate), 32 bags of concrete, 26 rails, and about 320 pickets if you use standard 3.5-inch boards.
Codes and permits: Many towns cap front-yard fences at 3 to 4 feet. Four feet (48 inches) is also the minimum height many pool barrier codes require.
