Fence Calculator
This counts the materials in a fence run. Give the total length, the post spacing you want and any gate openings, and it returns the sections, the posts they need, the rails and the preassembled panels, along with the spacing you actually end up with once the run divides evenly. A second mode counts pickets from the board width and the gap between them, with an optional waste allowance. It counts materials only and leaves prices to the fence cost calculator, because wood, vinyl and chain link differ far too much to average.
