Fence Calculator
Estimate posts, panels, rails and concrete for any fence.
How the fence calculator works
Posts = fence length ÷ spacing + 1 (for the end post). Panels = length ÷ spacing. Rails = panels × rails-per-section (2 for short fences, 3 for tall or heavy panels). Plan on ~2 bags of 60 lb concrete per post.
