Fencing a 20 Acres Property
A 20 acres lot is approximately 871,200 square feet. If the lot were perfectly square, the total perimeter would be about 3734 feet. In practice, most homeowners fence three sides (the house covers one), giving an estimated fencing run of 2800 linear feet.
For wood privacy fencing at this length, you need 355 posts, 710 bags of concrete, 8960 pickets, and 1050 rails. Total material cost: $42,000–$70,000.
For properties this size, split rail fencing is worth considering at just $28,000–$50,400 in materials. It defines the boundary clearly at a fraction of the cost of privacy fencing.
