1-Rail Fencing – Minimalist Boundary

Description & Use

  • Typically sits around 0.6 m above ground 
  • Ideal as a decorative boundary marker—think garden edges, entrance accents, or boundary definitions without obstructing views.

Pros

  • Cost-effective: Uses minimal material.
  • Simplified installation: Fewer elements mean faster assembly.

Cons

  • Limited containment: Not recommended for animal or child safety.
  • Minimal visual presence: May not provide desired structure for larger properties.

2-Rail Fencing – Subtle and Functional

Description & Use

  • Stands around 0.9 m tall 
  • Great for defining boundaries while still maintaining openness—suitable for gentle landscape demarcation and small-animal guidance.

Pros

  • Maintains a simple, open-faced aesthetic.
  • Still relatively inexpensive and easy to install.

Cons

  • Not secure enough for large animals or high-traffic environments.

3-Rail Fencing – Balanced Strength & Style

Description & Use

  • Finished height typically approximately 1.2 m above ground 
  • A versatile option for containing most livestock, including horses—widely used across rural settings 

Pros

  • Balanced budget-friendly pricing and functionality.
  • Popular aesthetic—classic appeal with practical strength.
  • Posts reach a height adequate for most large animals 

Cons

  • Depending on animal behavior, it may offer less security than a higher rail configuration.

4-Rail Fencing – Maximum Safety & Impact

Description & Use

  • Also around 1.2 m tall, similar to 3-rail, but with better spacing and sturdier structure 
  • Preferred where heightened safety or visibility is needed—especially with spirited livestock or to elevate curb appeal 

Pros

  • Tighter spacing reduces risk of animals escaping or leaning through.
  • Offers a more substantial, commanding visual presence.
  • Enhanced structural support, ideal for busy or high-stress environments.

Cons

  • More costly due to added materials.
  • Slightly more labor-intensive to install.
