Frequently Asked Questions

Q

How many fence posts do I need per 100 feet?

At standard 8 ft spacing, you need about 13–14 posts per 100 ft of fence. High-tensile wire can use 12–20 ft spacing between line posts, while board fencing typically uses 8 ft spacing. Corner and brace posts are additional.

  • 8 ft spacing (standard): ~13 posts per 100 ft
  • 10 ft spacing (high tensile): ~11 posts per 100 ft
  • 12 ft spacing (electric): ~9 posts per 100 ft
  • Add corner posts at every direction change
  • Add brace posts (2 per corner) for tension support

Q

What is the best fencing for cattle vs goats?

Cattle do well with high-tensile 5-strand or barbed wire. Goats need woven wire (no-climb) because they squeeze through strand fencing. Horses require board or smooth high-tensile — never barbed wire due to injury risk.

  • Cattle: high tensile 5-strand or barbed wire
  • Goats: woven wire (no-climb) is mandatory
  • Sheep: woven wire with tight bottom spacing
  • Horses: board fence or smooth high-tensile only
  • Electric: works as a supplement for all species
Q

How much does livestock fencing cost per foot?

Woven wire fencing costs $2–$4 per linear foot installed. High-tensile is $1.50–$3 per foot. Board fencing is the most expensive at $5–$12 per foot. Electric is cheapest at $0.50–$1.50 per foot but needs a charger.

  • Woven wire: $2–$4/ft (most versatile)
  • High tensile: $1.50–$3/ft (lowest maintenance)
  • Board fence: $5–$12/ft (most attractive)
  • Electric: $0.50–$1.50/ft (cheapest, needs charger)
  • Add $200–$500 per gate installed
Q

How many gates should I include?

Plan at least 1 gate per paddock for equipment access (12–16 ft wide) plus walk-through gates (3–4 ft) for daily use. For rotational grazing, each subdivided paddock needs its own gate.

  • 1 equipment gate per paddock (12–16 ft wide)
  • 1 walk-through gate per 100 ft of fence
  • Rotational grazing: 1 gate per paddock division
  • Corral areas: multiple gates for livestock flow
  • Budget $150–$400 per metal gate
