What This Calculator Does

Calculate posts, rails, pickets, and concrete for a fence.

It combines Fence Length, Fence Height, Post Spacing, Number of Rails to estimate Posts Needed, Rails Needed, Pickets Needed.

Formula & Method

Sections =\left\lceil\frac{Length}{Spacing}\right\rceil, posts =Sections+1, rails =Sections\cdot RailsPerSection, pickets =\left\lceil\frac{12Length}{PicketWidth+Gap}\right\rceil.

Notation used in the formulas: R = Posts Needed; x_{1} = Fence Length; x_{2} = Fence Height; x_{3} = Post Spacing; x_{4} = Number of Rails; x_{5} = Picket Width; x_{6} = Picket Gap.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
