A post installation templating assembly for positioning fence posts for setting includes a bar and a pair of brackets. Each bracket is coupled to and extends perpendicularly from a respective opposing end of the bar. Each bracket is configured to selectively couple to a respective post to parallelly position a pair of posts perpendicularly to the bar. The bar is configured to fixedly separate the pair of posts so that the pair of posts can be set with a separation equivalent to a distance between the pair of brackets.
