Don’t Wing It – Use this Guide for Proper Electric Fence Post Spacing

Installing an effective electric fence requires careful planning and execution. One of the most critical factors is determining the ideal spacing between fence posts. Proper post spacing ensures your electric fence can reliably contain livestock for years to come. Too far apart, and the fence wires will sag. Too close together, and you’ll spend more than necessary on supplies and installation. Use this comprehensive guide to identify the optimal electric fence post spacing for your unique needs.

We’ll explore the key variables you need to evaluate, from fence purpose and livestock type to terrain and wildlife pressure. You’ll also find recommended spacing guidelines for different situations. With the right spacing, your electric fence will have the strength and stability to handle everything from cattle rubbing to winter snow loads.

Key Considerations for Determining Post Spacing

Identifying your ideal electric fence post spacing depends on several important factors:

Type of Electric Fence

Are you installing a temporary or permanent electric fence? This makes a big difference in ideal post spacing:

  • Temporary electric fences are designed for quick and easy setup and takedown. Posts can be spaced further apart, typically about 50 feet.
  • Permanent electric fences need to stand the test of time without leaning or sagging. Much closer post spacing is required, generally 12-30 feet apart.

Evaluate your needs to choose the right fencing for your situation.

Livestock Type

The animals your fence will contain also impact spacing. Larger, stronger livestock require reinforced containment:

  • Cattle need strong fencing capable of withstanding rubbing and leaning. Closer post spacing is recommended.
  • Sheep and goats are less demanding on fences. You can often get by with slightly wider post spacing for small ruminants.

Consider the typical livestock for your operation, both now and in the future. Plan your post spacing accordingly.

Terrain and Topography

The lay of your land significantly influences post spacing needs:

  • On flat terrain with good drainage, you can usually space posts further apart, around 20-30 feet.
  • For rolling hills or uneven ground, more frequent posts every 15-20 feet helps the fence stay upright through rises and dips.
  • In steep hill country, very close spacing of 10-15 feet is often needed to prevent slides.

Proper post spacing is crucial for maintaining fence integrity on sloped and uneven land. Consider topography carefully.

Wildlife Pressure

Areas with high wildlife activity also call for closer post spacing:

  • When there’s constant deer, elk, or other animal pressure, space posts just 10-15 feet apart.
  • Reinforced posts may be needed in extremely high traffic areas to withstand frequent animal encounters.

Prevent animals from creating weak spots by planning for likely wildlife run-ins.

Overall Fence Height

The overall height of your electric fence affects the post support required:

  • Standard spacing guidelines assume 1-2 meter (3-6 foot) high fencing.
  • Significantly taller fences need sturdier posts at closer intervals to handle the added height and wire tension.

Adjust spacing accordingly for fences well above or below typical heights.

Electrical Power

Lastly, the strength of your electric fence charger impacts spacing needs:

  • With an underpowered, inadequate charger, you’ll need more frequent posts for conductivity.
  • A strong, high voltage output charger allows you to space posts further apart while still transferring electricity.

A robust charger enables wider spacing between conductive posts.

Recommended Post Spacing

Now that we’ve covered the key factors that determine post spacing, let’s look at typical recommendations:

Temporary Fences

As discussed above, temporary electric fences are designed for quick and easy installation. Typical spacing guidelines are:

  • About 50 feet between posts works well for most situations.
  • Allows for rapid setup and takedown.

For temporary containment lasting a few days up to a season, 50 feet is usually sufficient.

Permanent Fences

Permanent electric fence posts need much closer spacing to stand the test of time:

  • Spacing of 12-30 feet prevents posts from leaning and wires from sagging.
  • Accommodates livestock pressure, terrain changes, and weather over many years.

Install posts 12-30 feet apart for a long-lasting permanent barrier.

By Livestock Type

Typical electric fence post spacing by animal includes:

  • Cattle: 12-20 feet
  • Sheep & Goats: 15-30 feet
  • Horses: 12-16 feet
  • Poultry: 5-8 feet

Adjust as needed based on livestock numbers, terrain, and other factors.

Based on Terrain

Recommended post spacing based on land type:

  • Flat terrain: 20-30 feet
  • Rolling hills: 15-20 feet
  • Steep hills: 10-15 feet

Posts need to be closer together as the terrain gets steeper.

High Wildlife Areas

In regions with regular wildlife activity:

  • Space posts 10-15 feet apart.
  • Use reinforced posts as needed.

This prevents animals from damaging or escaping through the fence.

Pro Tips for Optimal Spacing

Here are some additional professional recommendations for ideal post spacing:

  • Check your local agricultural codes for any spacing requirements or restrictions.
  • Consider possible future changes, like adding cattle to a sheep operation.
  • Allow extra room for repairs and maintenance access.
  • Budget for additional posts in undulating areas.

Think through all potential factors when planning your electric fence post spacing.

Determining proper electric fence post spacing requires evaluating your unique terrain, livestock, wildlife pressure, fencing height, and a variety of other considerations. While general recommendations provide a starting point, your specific spacing needs may vary.

Careful planning and installation of posts at optimal intervals gives your electric fence the strength and stability to serve its containment purpose for years to come. Proper spacing prevents sagging wires, leaning posts, and weak spots. It also deters animal escapes and damage from livestock leaning or wildlife encounters.

Use this comprehensive spacing guide as a resource when planning your electric fencing project. Choosing the right post intervals can mean the difference between an intermittent nuisance and an effective, lasting barrier. With strategic spacing for your situation, you can depend on your high-tensile electric fence to securely contain livestock season after season.
