How we work it out

  • Posts: each side is split into equal gaps no wider than your post spacing. A paddock shares its 4 corner posts; a straight line has a strainer at each end. Each gate adds one post (two gate posts where one line post would be).
  • Wire: fence length (gate openings taken out) × number of wires, plus 5% for tying off and joins. Rolls are rounded up.
  • Area: length × width, shown in hectares and acres (1 ha ≈ 2.47 acres).

This is a quick estimate for a rectangular paddock or a straight run on flat ground. Hills, curves, creek crossings, electric offsets, stays, droppers and your fencing contractor's methods all change the real numbers, so check with your supplier or contractor before you buy. Nothing you type is stored or sent anywhere. Need other units? Try the farm unit converter; words like strainer or paddock are in the farm words glossary.
