Fence Material Calculator

Estimate pickets, posts, and rails for a wood picket fence.

Fence length (linear feet) Picket width (inches) Gap between pickets (inches — 0 for a solid privacy fence) Post spacing (feet, typically 8) Rails per section (typically 2; 3 for tall fences)

How this worksPickets: total fence inches ÷ (picket width + gap), rounded up. Posts: fence length ÷ post spacing gives the number of sections, rounded up, plus one post for the end. Rails: sections × rails per section. Always buy a few extra pickets — boards warp and splits happen.
