Frequently asked questions
- How many pickets does a privacy fence need?
- A privacy fence butts the boards nearly tight, so it uses the most pickets of any style. The calculator divides the fenced length by the picket width plus a hairline gap and rounds up.
- Why leave any gap at all?
- Wet or treated boards shrink as they dry. A small gap, about an eighth of an inch, keeps the fence from buckling later while still blocking the view.
- How many rails for a 6 ft privacy fence?
- Three rails are standard at 6 ft to keep tall boards from cupping. The calculator picks two, three or four rails from your height.
- How accurate are the picket and rail counts?
- They are close planning estimates. A privacy fence butts boards tight, so real coverage shifts with board shrinkage and the exact gap you set, and sloped ground adds pickets, so buy about ten percent extra and confirm before you order.
