Frequently Asked Questions
How far apart should fence posts be?
Standard post spacing: 6–8 feet (1.8–2.4m) for wood privacy and picket fences. Split-rail fences typically use 8-foot spans. Metal posts for chain-link: 8–10 feet. Always check local building codes and the fence manufacturer's recommendations for maximum unsupported spans.
How deep should fence posts be set?
General rule: bury 1/3 of the post length or at least 24 inches deep, whichever is greater. For a 6-foot post: bury 2 feet, leaving 4 feet above ground. In frost zones, posts must extend below the frost line (varies by location: 12–48 inches in the US). Set posts in concrete for stability.
How much concrete do I need per fence post?
A standard post hole (10" diameter × 24" deep) needs approximately 1–1.5 bags of 50-lb fast-setting concrete mix. For an 8" hole at 24" depth: about 0.8 bags. This calculator provides the total bag count for your entire fence run.
