How far apart should fence posts be?

Space posts 6–8 ft on center; closer spacing adds strength in windy areas.

Use two rails for fences under 5 ft and three rails for taller privacy fences.

Enter the fence length, post spacing, and picket sizing to get the number of posts, rails, and pickets needed.

Estimates only. Round up and buy a little extra to account for waste, spills, and breakage.

Sections = length ÷ post spacing. Posts = sections + 1. Pickets = (length × 12) ÷ (picket width + gap).
