Safety and security are a priority when constructing fencing for horses. For this reason, wire fencing with smaller stay spacings of 2 or 3" is used, this prevents injury from horses "pawing" at the fence. "New Zealand" style high tensile and barbed wire should be avoided due to the risk of entanglement.  

Non-climb wire is an excellent choice for containing horses. Its 2"x 4" box prevents hoof intrusion. It is available in heights of 48" or 60". Fixed knot woven wire in stay spacings of 3" is also an alternative. 

We recommend the use of all wood posts on 12' centers. T-posts should be avoided due to the risk of injury.  

Typically, an electric wire will be added above to increase height and prevent horses from leaning over the fence.
