5. Add the slat or picket spacing to the width of each one, then divide this number into the total length of the fence to find the number of slats or pickets you need. For example, if you're using 6-inch slat, which is 5 1/2 inches wide, and you're spacing them by 1/2 inch, you need 400 of them for a 200-foot fence.. Lay out the perimeter of the fence and mark the corners with stakes. Measure the distance between each pair of corners with a 100-foot tape measure. Add these distances to get the total length of the fence. For example, a fence with four equal sides of 50 feet each has a total length of 200 feet.
