Post spacing is usually set by the panel or rail length of your fence type. This chart gives the typical spacing for common fences, measured on center.
| Fence type | Post spacing |
|---|---|
| Wood privacy | 6 – 8 ft |
| Chain link | up to 10 ft |
| Vinyl panel | 6 – 8 ft per panel |
| Ranch rail | 8 ft |
| Picket | 6 – 8 ft |
Set posts deep. Bury about one-third of the post length and extend below the frost line, set in concrete. Closer spacing adds strength on windy or sloped sites.
FAQ
Does fence post spacing change with fence height? Yes, taller and heavier fence sections generally need closer post spacing (or larger posts) to resist wind load and prevent sagging, while shorter, lighter fencing can use wider spacing between posts. Corner and gate posts typically need to be set deeper and sometimes larger in diameter than standard line posts due to the extra lateral load they carry.
