Fence Specifications

Horserail guidelines for building rail and coated wire horse fencing—including post spacing, fence height, and post sizing recommendations.

Spacing Guidelines

Post Spacing

The ideal post spacing for horse fences depends on the type and pressure. Rail fences are typically set 8–12 feet apart, while coated wire fences range from 8–20 feet.

Area Type	Pressure Level	Rail Spacing	Coated Wire
Lots	Heavy Pressure	8' (245cm)	8' (245cm)
Pasture	Medium Pressure	10' (305cm)	16' (490cm)
Range	Average Pressure	12' (365cm)	20' (610cm)
Light Grazing	Light Pressure	12' (365cm)	20' (610cm)

Pro Tip: Extra rails and closer post spacing may cost more, but the additional density increases the solidity of the fence.

Height Guidelines

Fence Height

Proper fence height ensures safety and secure containment for your horses.

54″

Standard Height

1.4m

Recommended horse fence height for most pasture and containment applications.

Best for: General pasture fencing

5-6′

High-Pressure Areas

1.5-1.8m

For arenas, turnout lots, or corrals where horses face more pressure and may attempt to jump.

Best for: Arenas, corrals, stallion enclosures

Taller fences facilitate safety and secure containment for high-value horses, stallions, and in areas where horses are under increased pressure.

Post Guidelines

Post Sizing

Whatever height is chosen, the appropriate post length must be used. Different post types require different dimensions based on their function in the fence line.

Post Type	Diameter	Length (Soft)	Length (Concrete)	Embedment
Line Post	4"-5" (107mm-127mm)	8' (245cm)	7' (215cm)	Min. 2.5' (76cm)
Corner Post	5"-6" (127mm-152mm)	9-10' (275cm-305cm)	8' (245cm)	3.5'-4' (107cm-122cm)
End/Gate Post	7"-8" (178mm-203mm)	9-10' (305cm-365cm)	8' (245cm)	4.5'-5' (137cm-152cm)

*Note: Frost depth must be considered when determining embedment depth in cold climates.

*Important: Use consistent measurements. Confirm recommended fence parameters for your specific installation.

Common Questions

Frequently Asked Questions

Get answers to common questions about fence specifications.

How far apart should rails be on a horse fence?

Rails are typically spaced 7″ to 11″ (18-28cm) apart, depending on the number of rails used. This amount of spacing discourages horses from reaching through the fence and reduces the risk of foot, leg, and head entrapment. Wider spacing can be achieved in electric fencing since horses avoid the fence.

How much ground clearance should a horse fence have?

The bottom rail of a horse fence should have about 12″ (30cm) of clearance from the ground. This height helps prevent animals from going under the fence and allows for mower access.

How many rails do you need for a horse fence?

Most horse fences use 3 or 4 rails. Three rails are common for pastures and general containment, while four rails adds coverage especially in taller fences, making them ideal for foals, stallions, or high-value horses. The right choice depends on safety needs, property layout, and horse behavior.

What is the correct 3-rail post spacing?

A 3-rail horse fence typically uses posts set 8′ to 10′ (2.4–3m) apart, with rails spaced evenly to create strong visibility and security. This layout balances cost and durability, while keeping horses safely contained. For higher pressure areas, tighter 8-foot spacing is recommended to maintain long-term fence strength.

What is the correct 4-rail post spacing?

Most 4-rail horse fences use 10′ (3m) post spacing. In high-pressure areas, posts should be set closer at 8′ (2.4m) to increase strength and safety. In lower-pressure areas, spacing can extend to 12′ (3m) without sacrificing effectiveness.
