What You Need for 100 Feet of Fence
A 100-foot wood privacy fence (the most popular residential choice) requires 16 posts set every 8 feet, 32 bags of 60-pound fast-setting concrete, approximately 320 pickets (3.5-inch width with 1/4-inch gaps), and 39 horizontal rails. Material costs typically range from $1,500 to $2,500.
If you prefer a more affordable option, chain link fencing for 100 feet uses 13 posts with 10-foot spacing and 2 rolls of galvanized mesh, costing $800–$1,500. Vinyl panels offer a low-maintenance alternative at $2,000–$3,500 with 13 pre-assembled panels.
For a DIY project of this size, plan on roughly 2 days of work. Renting a two-person power auger ($50–$75/day) cuts digging time in half compared to a manual post hole digger.
