Divide fence run by post spacing and add one for the starting post. Standard wood privacy fence uses 8 ft OC spacing.
Line Posts = floor(Fence Length ÷ Spacing) + 1Add corner posts (often 4×4 or 6×6), terminal posts at ends, and double gate posts at each opening.
Total = Line Posts + Corner Posts + Gate PostsTypical 10″ diameter × 30″ deep hole uses ~1.4 cu ft per post. Two 50 lb bags per hole is common.
Concrete (cu ft) = π × (Diameter/2)² × Depth × Post CountUpdated: July 2026
100 ÷ 8 + 1 = 14 line posts plus 2 end posts = 16 posts. At 1.4 cu ft/hole, need ~22 cu ft concrete (~33 bags).
180 ft at 8 ft OC = 24 line posts + 2 corner posts + 1 gate (2 posts) = 27 posts total.
200 ft pasture fence at 10 ft spacing needs 21 posts. Wider spacing reduces post count but requires heavier rails.
Plan fence post layout before digging holes or buying lumber. Enter total fence length, post spacing (typically 6 or 8 ft on center), and count of corners, ends, and gates to get total posts and concrete volume for footings.
