Place a wood stake into the ground at each corner or end of the fence and tie a continuous length of nylon string to the stakes to define the fence perimeter and location. Add two additional stakes at either side of any desired gate location in the fencing. Calculate the number and length of fence posts.Measure the length of each side and divide measurement by the recommended post spacing for the type of fence. Be sure to include only one post at each corner and two posts at each gate.or the horizontal rails, multiply the overall length of the fence times the number of rails for the total length of material needed. Calculate the fencing material. Divide the overall length of the fence calculated in Step 4 by the individual board or picket width including spacing for each.
