Posts Required vs Fence Line Length
Formule
## 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.
Exemple Résolu
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
Questions Fréquentes
Why does spacing need to be equal?
Equal spacing ensures uniform appearance and consistent panel sizing. It also distributes wind loads evenly across all posts.
Should I use concrete for every post?
Concrete is recommended for all posts in fence lines exposed to wind. Some installers skip concrete for intermediate posts on short fences, but this can lead to leaning posts over time.
