Fence Calculator
Estimate posts, panels, rails and concrete for any fence.
A fence estimate requires the total run length, post spacing, and panel style. The number of posts equals the run length ÷ spacing (usually 6–8 ft), plus one, with an extra post at every corner and gate. Each 6 ft panel section needs 2–3 rails and 16–17 pickets at standard spacing. Enter your run length to calculate the required posts, rails, pickets, and concrete.

How does the fence calculator work?
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.
