A rabbit-proof garden fence needs a minimum 30-inch above-ground height, a 12-inch buried L-shaped base extending outward, and ½-inch hardware cloth mesh to stop both jumping and digging.
One night of hungry rabbits can level a vegetable patch you’ve tended for months. The fix is a fence built to the exact specifications that stop them cold — above ground, below ground, and at the mesh level. Here is the proven design and the step-by-step install that keeps rabbits out without guesswork.
What Makes a Fence Rabbit-Proof: The Core Specs
Three measurements matter more than anything else, and getting any one wrong gives rabbits an opening. The above-ground height blocks jumping, the buried depth and L-bend stop digging, and the mesh size prevents squeezing.
- Above-ground height: Minimum 30 inches (76 cm).
- Below-ground depth: At least 12 inches (30 cm) of vertical burial.
- L-shaped bend: The bottom 6 inches of mesh bent outward at a 90-degree angle, facing away from the garden.
- Mesh size: ½-inch (1.27 cm) openings or smaller. Rabbits squeeze through anything larger — even 1-inch holes are a risk.
Galvanized hardware cloth is the best material choice: chew-proof, rust-resistant, and rigid enough to hold the L-shape. Vinyl-coated fencing works too and adds extra corrosion protection.
Rabbits Jump, Dig, and Squeeze: How the Fence Stops Each
Rabbits use three escape methods, and a fence that blocks only one or two still fails. This design covers all three.
Jumping
Rabbits can clear a 24-inch fence without much effort. The 30-inch minimum height forces them to attempt a jump they cannot make from a standstill, and the lack of a landing ledge on your side stops them from climbing the mesh.
Digging
Burying the fence straight down is a common mistake — rabbits dig alongside it and pop up inside. The outward L-bend creates a barrier underground that baffles them: they dig down, hit the bent mesh, and cannot find the edge.
Squeezing
Adult rabbits fit through a 2–3 inch gap, and young ones slip through 1-inch holes. The ½-inch mesh leaves no space. Chicken wire with larger diamond openings is the usual failure here — use hardware cloth instead.
Materials and Dimensions: What You’ll Need
| Component | Specification |
|---|---|
| Mesh material | Galvanized hardware cloth or vinyl-coated fencing |
| Mesh opening | ½ inch (1.27 cm) or smaller |
| Fence height above ground | 30 inches (76 cm) minimum |
| Buried depth | 12 inches (30 cm) |
| L-bend at base | 6 inches (15 cm) bent outward at 90° |
| Post spacing | 6.5–8.2 feet (2–2.5 meters) apart |
| Corner post depth | 12 inches (30 cm) into ground |
| End/support posts | 24 inches (60 cm) deep for stability |
| Tension wire | 2 mm or 2.5 mm line wire at top and bottom |
| Trench width | 6 inches (15 cm) |
| Overlap at joins | 4 inches (100 mm) minimum |
Installation Steps: How to Build the Fence
Follow this order to avoid rework. The whole job takes a weekend for a typical garden.
- Mark the perimeter and dig the trench. Outline the fence line, then dig a trench 6 inches wide and 5 inches deep around the entire boundary. This trench holds the buried L-flap.
- Set the corner posts first. Hammer posts 12 inches deep at each corner. Space intermediate posts 6.5 to 8.2 feet apart along the straight runs.
- Roll out the mesh and create the L-bend. Lay the hardware cloth flat. Bend the bottom 6 inches upward at a 90-degree angle to form an outward-facing lip. Wirefence.co.uk’s installation guide shows this L-bend detail.
- Install the top tension wire. Run a 2 mm or 2.5 mm line wire along the top of the posts. Secure it with staples on wood posts or clips on metal ones.
- Attach the mesh to the tension wire and posts. Start at a corner post. Fix the mesh top to the tension wire first, pulling it taut. Staple to posts every 6 inches (15 cm), leaving a little slack for temperature movement.
- Secure the bottom tension wire and bury the L-flap. Run the bottom tension wire through the mesh at the bend point. Place the L-shaped flap into the trench, staple it at the 90-degree bend and the outer edge. Backfill with 5 inches of soil or mulch to hold it down.
- Overlap adjoining sections by 4 inches where rolls meet. This prevents gaps that rabbits find fast.
- Check the whole fence for gaps. Walk the perimeter. Pay special attention to gate bottoms — bury hardware cloth there too, because rabbits dig under gates more often than fence runs.
Common Mistakes and How to Avoid Them
These errors appear in almost every failed rabbit fence. Skip them and your fence works the first time.
- Fence too short. Below 24 inches, rabbits jump it easily. Go to 30 inches.
- No L-bend. Burying mesh straight down means rabbits dig alongside and enter right under the fence. The outward L-bend is non-negotiable.
- Wrong mesh size. Chicken wire with 1-inch or larger holes is an invitation. Use ½-inch hardware cloth.
- Staples too tight. Tight staples leave no room for expansion and wear through the wire. Leave a little play.
- Gate gaps. The gate is the weakest point. Bury the same L-bend flap under the gate opening.
- No overlap at joins. A 4-inch overlap sounds generous but saves you from finding a rabbit-sized gap later.
Installation Checklist: Confirm Every Step Before Calling It Done
| Checkpoint | What to Confirm |
|---|---|
| Height | At least 30 inches above ground along the entire fence line |
| Burial depth | 12 inches below surface, plus the 6-inch L-bend |
| Mesh opening | No larger than ½ inch at any point |
| L-bend orientation | Outward, away from the garden, at a 90° angle |
| Post stability | |
| Tension wires | Top and bottom lines tight, no sagging |
| Joins overlapped | Minimum 4 inches at every roll connection |
| Gate base | Buried hardware cloth with the same L-bend |
| Staple tension | Secure but not crushing the wire |
The checklist above is your final pass before you walk away. Every item validated means zero rabbit problems this season.

FAQs
Will a 2-foot fence keep rabbits out?
A 2-foot fence is too short for most adult rabbits. They can clear 24 inches from a standstill, and a running start makes it easy. The safe minimum is 30 inches to block jumping reliably.
Can I use chicken wire instead of hardware cloth?
Standard chicken wire has diamond openings that are too large — rabbits squeeze through anything over 1 inch. Galvanized hardware cloth with ½-inch mesh is the right choice and stops chewing better.
How deep should I bury a rabbit fence?
Bury the fence at least 12 inches deep, with the bottom 6 inches bent outward at a right angle. The L-shape is the key: straight burial lets rabbits dig alongside and slip under.
Does the L-bend need to face inside or outside the garden?
The L-bend must face outward, away from the garden. Rabbits digging from outside hit the bent mesh and cannot find the edge to go around. Facing inward lets them dig down and re-enter.
What is the best material for a rabbit-proof fence?
Galvanized hardware cloth is the top choice — it resists rust, withstands chewing, and holds its L-bend shape. Vinyl-coated fencing also works well and adds extra corrosion resistance.
