Posts Required vs Fence Line Length
Fence Post Spacing
Posts = ceil(Length / Spacing) + 1
To make all sections equal, divide the total length by the number of sections. Budget about 2 bags of concrete (50 lb) per post for proper setting. Corner and gate posts may need extra concrete.
Example Calculation
80 ft fence line at 8 ft target spacing.
- 01Sections = ceil(80 / 8) = 10
- 02Posts = 10 + 1 = 11
- 03Equal spacing = 80 / 10 = 8.00 ft
- 04Concrete = 11 x 2 = 22 bags
