A deer fence is a physical barrier, typically 8 feet tall, built from woven wire, welded wire, or heavy-duty polypropylene netting, designed specifically to stop white-tailed deer from jumping into gardens, crops, and young woodlands.
White-tailed deer can clear 7 to 8 feet from a standing start and jump higher with a running approach, which is why most 4- or 5-foot garden fences do nothing but slow them down. Whether you are protecting a vegetable patch or a young tree plantation, the barrier works the same way: if they cannot jump it and cannot push through it, they move on.
How Tall Does a Deer Fence Actually Need to Be?
Two alternative designs can work at lower heights by disrupting the deer’s depth perception:
- Slanted fences set at a 45-degree angle can be effective at 5 to 6 feet because the tilt confuses the deer’s ability to judge the landing zone.
- Double parallel fences — two 4-foot barriers spaced 4 feet apart — create a visual gap the deer cannot read, stopping them at a combined height well under 8 feet.
What Materials Are Deer Fences Made From?
Three main material types dominate the market, and each serves a different budget and lifespan goal. For a good comparison of specific products and prices, check out our tested roundup of the best fences for deer.
- It is lightweight, UV-treated, flexes on impact, and springs back. Lifespan is 3 to 7 years before UV breakdown. Good for temporary or budget installations.
- Rigid, permanent, and lasts 15 to 25-plus years.
- Heavy-gauge metal, the most durable option. Same 15- to 25-plus-year lifespan.
- Electric deer fence: A 3-strand high-tensile or zig-zag tape design, often 5 feet high, using brief shocks to disrupt the deer’s depth perception. Requires continuous energization.
Installation: Key Steps and Common Mistakes
The Cornell Small Farms guidelines for woven wire and electric deer fence construction provide a reliable step sequence. For an 8-foot woven-wire fence with wooden posts, follow this order:
- Clear the fence line. Remove significant brush so you have clear access. Sometimes repositioning the fence is cheaper than clearing dense brush.
- Set corner assemblies. Use rigid or swing corners secured with deck screws or joist hanger nails.
- Set line posts.
- String wire.
- Attach the fence fabric. Unroll and suspend the fence.
- Apply tension.
Three mistakes sink most DIY deer fences: installing a 6-foot fence (hungry deer clear it easily), failing to stake the bottom tight (deer push under), and building gates shorter than the fence (the first weak point they find).
FAQs
Will a 6-foot fence keep deer out?
A 6-foot fence will not reliably stop white-tailed deer. From a standing start, deer can clear 7 to 8 feet, and a running jump adds more height. In areas with low deer pressure a 6-foot fence might work temporarily, but the honest minimum is 8 feet.
How long does polypropylene deer netting last?
UV-treated polypropylene netting typically lasts 3 to 7 years before the sun degrades it and it becomes brittle. Non-UV-treated netting breaks down much faster and is not worth installing. Check the product label specifically for UV treatment before buying.
Can deer push through or under a fence?
Yes, if the bottom is loose or the mesh is too large. Deer search for weak spots and will push under loose netting or through gaps larger than about 2 inches. Staking the bottom firmly to the ground and
