Rabbit Fence Garden Installation | Build a Barrier That Works

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

Installation Steps: How to Build the Fence

Follow this order to avoid rework. The whole job takes a weekend for a typical garden.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Overlap adjoining sections by 4 inches where rolls meet. This prevents gaps that rabbits find fast.
8. 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.
