What You Need for 320 Feet of Fence
A 320-foot wood privacy fence (the most popular residential choice) requires 43 posts set every 8 feet, 86 bags of 60-pound fast-setting concrete, approximately 1024 pickets (3.5-inch width with 1/4-inch gaps), and 120 horizontal rails. Material costs typically range from $4,800 to $8,000.
If you prefer a more affordable option, chain link fencing for 320 feet uses 35 posts with 10-foot spacing and 7 rolls of galvanized mesh, costing $2,560–$4,800. Vinyl panels offer a low-maintenance alternative at $6,400–$11,200 with 40 pre-assembled panels.
For a DIY project of this size, plan on roughly 6 days of work. Renting a two-person power auger ($50–$75/day) cuts digging time in half compared to a manual post hole digger.
