6 ft privacy fence, 8 ft post spacing, 5.5" pickets.
For a privacy fence with 5.5-inch (1×6) pickets and no gaps, approximately 2.2 pickets per linear foot. Semi-privacy with 1-inch gaps uses about 1.8 per foot.
8 feet is standard for most residential fences. Use 6 feet for taller fences (8 ft) or windy areas. Never exceed 10 feet between posts.
Bury at least one-third of the total post length. For a 6-foot fence, use 8-foot posts with 2 feet in the ground. For an 8-foot fence, bury 2.5–3 feet.
One 50-lb bag of fast-setting concrete per post for a standard 10-inch diameter hole at 24 inches deep.
Most areas require permits for fences over 6 feet. Many neighborhoods have HOA rules on style and height. Always check local building codes and call 811 to locate underground utilities before digging.
