Wood Privacy Fence Building Guidelines

A standard 6-foot residential privacy fence consists of structural vertical posts set in concrete, three horizontal 2x4 rails, and vertical dog-ear pickets.

Frequently Asked Questions

Rule of thumb: bury 1/3 of the total post length. For a 6-foot fence using an 8-foot post, dig at least 24 inches deep (or below your local frost line).

Always use 3 horizontal 2x4 rails for 6-foot and 8-foot privacy fences to prevent the wood pickets from warping, twisting, or cupping in the sun.
