How it works

Panels = fence length (minus gates) divided by panel width, rounded up. Posts = panels plus one, plus one extra post per gate.

Worked example

150 feet with one 4 foot gate needs 19 panels of 8 feet and 21 posts.

Frequently asked questions

Usually 6 to 8 feet, matching the panel width.

What about gates?
