A wire fence design refers to the physical description and spacings of the wire,line post and dropper components for a particular fence. The following specifications are typically required for an electric wire fence:

• description of wire

• number of wires

• wire spacings (from the ground)

• post spacing

• dropper spacing (if used)

These specifications must be chosen taking into account the various planning points; the three main ones being fence purpose, type of animal and site conditions. The other details of the fence such as post size, brace design, dropper type, etc. are set by construction practice once the above specifications have been selected.
