How we work it out
- Posts: each side is split into equal gaps no wider than your post spacing. A field 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 field 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.
