What You Need for 400 Feet of Fence
A 400-foot wood privacy fence (the most popular residential choice) requires 53 posts set every 8 feet, 106 bags of 60-pound fast-setting concrete, approximately 1280 pickets (3.5-inch width with 1/4-inch gaps), and 150 horizontal rails. Material costs typically range from $6,000 to $10,000.
If you prefer a more affordable option, chain link fencing for 400 feet uses 43 posts with 10-foot spacing and 8 rolls of galvanized mesh, costing $3,200–$6,000. Vinyl panels offer a low-maintenance alternative at $8,000–$14,000 with 50 pre-assembled panels.
For a DIY project of this size, plan on roughly 7 days of work. Renting a two-person power auger ($50–$75/day) cuts digging time in half compared to a manual post hole digger.
