How It Works

Standard fence post spacing is 6-8 feet on center. Posts should be set in concrete at a depth of 1/3 their total length (e.g., a 6-foot fence needs 8-foot posts buried 2 feet deep). Use one 80-lb bag of fast-setting concrete per post. Gate posts should be larger diameter (6x6 vs 4x4) to handle the extra stress. Always check local codes for property line setback requirements.
