Fence Footage for a 70×100 Yard
The perimeter of a rectangle is 2 × (width + depth). For 70 × 100, that is 2 × 170 = 340 feet. Most backyard fences only run three sides because the house closes off the fourth: one 70-foot back line plus two 100-foot sides, or 270 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 37 posts, 74 bags of concrete, 102 rails, and 864 pickets. Enclosing all four sides raises that to 46 posts and 1,088 pickets.
