Fencing a 40 Acres Property
A 40 acres lot is approximately 1,742,400 square feet. If the lot were perfectly square, the total perimeter would be about 5280 feet. In practice, most homeowners fence three sides (the house covers one), giving an estimated fencing run of 3960 linear feet.
For wood privacy fencing at this length, you need 500 posts, 1000 bags of concrete, 12672 pickets, and 1485 rails. Total material cost: $59,400–$99,000.
For properties this size, split rail fencing is worth considering at just $39,600–$71,280 in materials. It defines the boundary clearly at a fraction of the cost of privacy fencing.
