Fence Footage for a 80×100 Yard
The perimeter of a rectangle is 2 × (width + depth). For 80 × 100, that is 2 × 180 = 360 feet. Most backyard fences only run three sides because the house closes off the fourth: one 80-foot back line plus two 100-foot sides, or 280 feet. If your fence returns to the house partway along the side, measure that actual run instead.
For a wood privacy fence on three sides you'd buy about 38 posts, 76 bags of concrete, 105 rails, and 896 pickets. Enclosing all four sides raises that to 48 posts and 1,152 pickets.
