How much fencing material do I need?
Divide the total fence length by the post spacing (usually 8 feet) to get the number of sections, then add one post to close the run. Multiply sections by rails-per-section (2 for short fences, 3 for 6-foot privacy) for rails, and add a post on each side of every gate.

Frequently asked questions
How far apart should fence posts be?
Eight feet on center is standard and economical; six feet gives a sturdier fence for tall privacy panels or windy sites.
How many rails per section?
Use two rails for fences up to about 4 feet and three rails for 6-foot privacy fences to keep boards from warping.
