Privacy Fence Calculator
Calculate materials for a 6-foot privacy fence. Includes wind load considerations, proper post depth, and complete materials list.
How It Works
Privacy fences are solid fences with no gaps between boards. This calculator sizes everything for wind load — privacy fences catch significantly more wind than picket fences. In high-wind areas, post spacing is reduced to 6 feet and post depth increased. All privacy fences 6ft+ get 3 horizontal rails for strength. Post holes are deeper (36") for 8ft fences.
Frequently Asked Questions
How tall can a privacy fence be?
Most residential zoning allows 6-foot fences in backyards and 4-foot in front yards. Some areas allow 8 feet with a permit. Always check local codes and HOA rules before building. Some jurisdictions measure from the higher side on sloped lots.
Do privacy fences need deeper posts?
Yes. Privacy fences catch significant wind, creating lateral force on posts. Standard recommendation is 1/3 of total post length below ground: 6ft fence = 8ft posts with 24" buried. In high-wind areas, go to 36" depth.
What's the best wood for a privacy fence?
Cedar is the premium choice — naturally rot-resistant and beautiful. Pressure-treated pine is the most cost-effective and lasts 15-20 years. Redwood is excellent but expensive. All wood fences benefit from stain/sealant applied after installation.
How much wind load does a privacy fence handle?
A solid privacy fence can experience 20-30 lbs of force per square foot in a 60mph wind. That's over 700 lbs on a single 8-foot section. Proper post sizing and depth are critical for longevity.
