How to estimate fence
- Posts are spaced 6-8 ft on center; closer spacing is sturdier on windy or sloped sites.
- For a privacy fence pickets butt tight; for a picket-style fence add a gap, which lowers the count.
- Add a third rail for fences taller than 6 ft. Set posts in concrete below the frost line.
