Number of fence posts for a 1/2 acre lot

A 1/2 acre lot of land is 21,780 square feet with a circumference of 417 linear feet. Most fences use an 8 foot section of fence, so you will need to calculate the number of fence posts based on that.

A 1/4 acre plot of land is 10,890 which is the average land size right across America. A 1/4 acre lot has 208 linear feet around the perimeter.
