How Much Fence for a 100×200 Yard?

Fence Footage for a 100×200 Yard
The perimeter of a rectangle is 2 × (width + depth). For 100 × 200, that is 2 × 300 = 600 feet. Most backyard fences only run three sides because the house closes off the fourth: one 100-foot back line plus two 200-foot sides, or 500 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 66 posts, 132 bags of concrete, 189 rails, and 1,600 pickets. Enclosing all four sides raises that to 78 posts and 1,920 pickets.
