Your 100-Foot Post & Rail Shopping List
Simple, ranch-style fence with smooth or rough-sawn rails between posts. More finished look than split rail. Popular for horse properties and acreages.
At 8-foot spacing, 100 feet divides into 13 sections. That means 14 line and end posts, plus 2 gate posts if you add a walk gate, for 16 posts total. Each post takes 1 bags of 60 lb concrete, so buy 16 bags. With 3 rails per section you need 39 rails.
Doing it yourself, material cost is about $800–$1,500. Hiring a contractor typically adds $5–$15 per foot in labor, or about $500–$1,500 for this length, for an installed total near $1,300–$3,000. Prices vary by region, so treat these as planning numbers.
