Electric Fencing for Goats: Strand Count and Spacing
Published: October 19, 2026 · 10 min read
An electric fence for goats needs four strands at minimum and five in practice: bottom wire 6 to 8 inches off the ground, top wire at 42 to 48 inches, no vertical gap wider than about 8 inches at chest height. Three strands holds a trained herd on an interior line. It will not hold goats on a property boundary.
The count is really a gap calculation. A goat investigates a fence with its nose and shoulders, and any opening wide enough for its head is one it will take. Cattle respect two wires because they are tall and heavy. A goat is 30 inches at the shoulder, covered in insulating hair, and certain the grass is better on the other side.
Three sources agree closely. NRCS standard 382 specifies four or more wires for sheep and goats. Virginia Cooperative Extension publishes exact heights for 3-, 4-, and 5-wire goat fences. Langston University recommends four to five strands at 42 inches or taller. What follows is the spacing, power, and cost behind that number — and the Fencing Material Calculator turns it into posts, wire, and dollars.
Wire Heights for a Goat Fence
Spacings below come from Virginia Cooperative Extension for sheep and goats, plus a taller perimeter on the last two rows.
| Strands | Height above ground (inches) | Top wire | What it holds |
|---|---|---|---|
| 3 | 8, 18, 30 | 30 in | Interior paddock line, trained goats only |
| 4 | 6, 16, 26, 36 | 36 in | Minimum perimeter, calm herd, strong energizer |
| 5 | 6, 12, 18, 28, 38 | 38 in | Standard perimeter for most homesteads |
| 5, tall | 8, 16, 24, 36, 48 | 48 in | Horned goats, jumpers, heavy browse pressure |
| 6 | 6, 12, 18, 26, 36, 46 | 46 in | Escape artists and high predator pressure |
The middle column is a shape, not a recipe: wires bunch low where a goat's nose and chest are, then spread above 30 inches where the animal is mostly hair and air — close where the shock must land, wider where it need not.
What Each Strand Is Doing
The bottom wire stops the crawl-under
Goats go under fences far more often than over them. Langston's guidance is blunt: goats crawl under rather than jump, so keep the bottom wire close to the ground. Six inches is the working number; above ten invites a kid to slide beneath.
Six inches is low enough that grass touches it by June, and one stem bridging wire to soil dumps voltage on the run. A fence reading 6,000 volts in April and 1,800 in July has a vegetation problem, not an energizer problem.
Chest height is where the gap has to close
Wires two and three, near 12 and 18 inches, sit where a goat pushes. Stand at the fence and look for any opening between 12 and 30 inches wider than your hand span. Head through means shoulders through, and by then the fence has failed.
That is why adding one hot wire to woven wire works so well. An offset 9 inches out at 12 to 15 inches of height stops goats leaning on the mesh and stops horned goats wedging their heads in the squares.
The top wire stops the climb
Goats climb feeders, hay bales, and the diagonal braces on corner posts — Langston warns against diagonal bracing on goat fence corners, so build H-braces or deadmen instead. A top wire at 42 to 48 inches closes the last easy route, and one offset wire a foot inside handles the jumper.
Strand Count by Fence Job
Most homesteads need two or three different fences, not one.
| Fence job | Strands | Wire type | Notes |
|---|---|---|---|
| Property perimeter | 5 (6 if horned or jumpers) | 12.5 ga high-tensile, Class 3 | Top wire 42–48 in; the one fence that must not fail |
| Interior paddock division | 3–4 | High-tensile or polywire | Trained goats only; cheap because it is replaceable |
| Woven wire plus hot wire | 1 offset (2 if horned) | Polywire on offset insulators | Offset 9 in out, 12–15 in up; best kid-proof barrier |
| Temporary paddock | Netting, 3–4 built in | Electric netting, 35–42 in | Fast to move; horned goats can tangle in the mesh |
| Kidding pen or hospital pen | Woven wire or panels | 4×4 mesh or cattle panel | Kids walk through 6×6 mesh; do not rely on electric here |
The perimeter gets the fifth wire because it must hold under pressure from both sides. Interior lines exist to be moved and rebuilt, so three or four strands of polywire are the right economy.
Power Matters More Than Strand Count
A five-strand fence on a weak energizer is a fence goats walk through once and never respect again.
What voltage to hold
Target at least 3,000 volts at the farthest point of the run, and 4,000 to 5,000 if you can. Below roughly 2,000 the shock registers as an annoyance, and a goat that pushes through learns exactly the wrong lesson. Test at the far corner, wet and dry.
Joules and fence length
Energizers are rated in joules and miles of wire, and goats multiply the wire: a 1,000-foot perimeter with five strands is 5,000 feet of conductor. Size for at least twice your wire length and add margin for brush. A 2-joule unit that looks generous on the box is undersized here; 6 joules suits a few acres.
Grounding is half the system
Most "weak fence" complaints are grounding failures. Drive three rods, 6 to 8 feet long, at least 10 feet apart; one rod is a dry-season gamble. Goats make grounding harder than cattle do — hooves and hair insulate them from the soil, so the shock has to travel through a wet nose or mouth.
Where soil dries hard, run a ground-return system: alternate hot and ground wires at least 6 inches apart, so the animal completes the circuit by touching both instead of relying on soil moisture. One extra strand, and the difference between a fence that works in August and one that does not.
Cost: Five-Strand Electric vs Woven Wire
Costs are typical 2026 US retail for DIY installation. Regional prices move; the ratio between options does not.
| Fence | Materials per foot | 1,000 ft | Lifespan | Predator barrier |
|---|---|---|---|---|
| 5-strand high-tensile electric | $0.75–1.50 | $750–1,500 | 20–30 years | None — coyotes walk between wires |
| 4-strand high-tensile electric | $0.65–1.30 | $650–1,300 | 20–30 years | None |
| 48 in woven wire field fence | $1.75–2.75 | $1,750–2,750 | 15–20 years | Good, if mesh is tight at the bottom |
| Woven wire + 1 offset hot wire | $1.95–3.05 | $1,950–3,050 | 15–20 years | Best combination for goats |
| Electric netting, 164 ft rolls | $0.80–1.10 | $800–1,100 | 3–6 years | Fair; nothing that digs |
Langston's comparison puts woven wire at least twice the cost of a five-strand high-tensile fence — roughly $1,000 more per 1,000 feet, matching the table. The extra money buys a physical barrier; electric buys cheap, movable paddocks, and rotation is the cheapest way to raise the carrying capacity of land you already own. That is the argument in how many goats per acre.
Fence and feed decide whether a goat herd is cheap or expensive. Size the hay and grain side with the Goat & Sheep Feed Calculator, which turns herd size and weight into monthly cost.
Training Goats to the Wire
An electric fence is a psychological barrier; it exists only once the animal has been shocked by a fence that was working. Build the habit first:
- Train in a small pen with a live wire inside. Good forage so they are not reaching through; most goats need one or two encounters.
- Never train on a weak or poorly grounded fence. A goat that pushes through once will test every fence after, and retraining is unreliable.
- Give them a reason to stay in. Goats break out for better browse. Inside grazed to dirt means the fence is not the problem.
- Walk the line weekly. Voltage at the far end, sagging or grounded wires, vegetation. One fallen branch shorts an entire run.
Where predation is real, pair the perimeter with a guardian animal or a woven barrier at ground level. Five strands stops goats; it does not stop a determined dog.

How many strands of electric fence do I need for goats?
Five for a permanent perimeter, four as the absolute minimum. NRCS standard 382 calls for four or more wires on sheep and goats, and Langston University recommends four to five at 42 inches or taller. Three suits an interior cross-fence.
Will three strands keep goats in?
Usually not for long. Three strands put wires at roughly 8, 18, and 30 inches, leaving gaps wide enough for a goat's head and shoulders. Once the head is through the body follows, so three strands is a paddock divider, not a perimeter.
How tall should an electric fence for goats be?
At least 42 inches to the top wire, 48 for horned goats or known jumpers. Goats crawl under more than they jump, so the bottom wire matters as much: 6 to 8 inches off the ground, clear of grass.
How many volts does a goat fence need?
Hold at least 3,000 volts at the farthest point and aim for 4,000 to 5,000. Below about 2,000 goats walk through the shock, learn the fence is not a barrier, and are hard to retrain. Test at the far end with a voltmeter.
The Build That Works
For most homesteads the answer settles at five strands of 12.5-gauge high-tensile wire: 6, 12, 18, 28, and 38 inches, with the top raised to 48 if you keep horned goats. Four strands is the code minimum and holds a calm herd behind a strong energizer. Three is a divider, not a fence.
Spend the difference on power, not a sixth wire: three ground rods, an energizer rated for twice your wire length, a weekly check at the far corner. All of it costs less than one goat.
