Fence Calculator — Posts, Pickets, Rails & Concrete
Spec no. 04How to use
Enter the total fence length in feet and post spacing (typically 6–8 feet). Posts = length ÷ spacing + 1. For pickets, enter picket width and gap in inches — pickets = (length × 12) ÷ (width + gap). Rails default to 2 per section between posts (set 3 for tall fences). The estimate includes concrete for the post holes.
