How the privacy fence page differs
The fetched Omni privacy fence page still uses the same post, rail, and picket math as a standard wood fence, but its design goal is visual screening. That makes picket spacing the key variable, because smaller gaps increase privacy.
Quantities behind a privacy fence layout
Number of posts = Fence length / Post spacing + 1
Number of rails = Rails per section x Number of sections
Number of pickets = Fence length / (Picket width + Picket spacing)
Post length = 1.5 x Fence height
Privacy strategy
If you need a true no-gap privacy screen, Omni points readers toward overlapping or tightly spaced pickets. This version lets you set picket spacing down to zero and compare that against a board-on-board design.
