How it works
Panels = length ÷ panel width (rounded up)
Divide the total length by the panel width and round up; a straight run needs one more post than panels. Add posts for corners and gates.

Frequently asked questions
Why one extra post?
A straight fence needs a post at both ends, so posts = panels + 1.
What about corners?
Each corner or gate usually needs an extra post — add them to the total.
