Fencing Calculator
Plan a point-to-point run or enclosed area: posts or wooden poles, Y-standards, droppers, Veldspan or fence wire, and soft galvanized binding wire. Built for typical South African farm fencing. Estimates only; confirm quantities before you order.
Fence suggestion
Optional. Pick a common layout to pre-fill height, wire lines, and spacings before you enter the distance.
Or leave custom and set values yourself.
Fence layout
Choose a point-to-point run or an enclosed area. Enclosed areas use total circumference and corner count. No square/rectangle sides needed.
Straight run from end to end
Height & wire lines
Height is kept for quote context. Set how many horizontal wire lines you want on the fence (not the gap between them).
Height above the ground, 0.6–2.5 m.
Auto: about 300 mm apart. Follows the height; type a number to set your own.
Main fence material
Fence wire diameter used for estimates: 2.24 mm. Wire quantities show metres with kilograms below (both rounded up).
Posts, Y-standards & droppers
Posts are corner / straining posts (each includes two stays), one per corner/end, and never more than the max post spacing without a post. Y-standards sit along the line. Droppers fill between them (1–3 m).
50–250 m · never longer without a post
5–50 m
Y-standard length
1850 mm
Shortest stock length for the fence height plus about 600 mm in the ground.
1–3 m
Light duty is the lighter dropper for small stock. Standard is the usual farm fence. Heavy duty is the stronger dropper for cattle and game. Rebar droppers are the cheaper option, made from rebar coated in Iscor black.
Dropper length
1,250 mm
First stock length taller than the 1.2 m fence.
Allowance for joins, strain, and offcuts
Post & stay sizes
We make posts and stays to length: your fence height plus the depth in the ground. The size below is an example straining post; check the diameter and wall thickness before you order.
Example: 76 mm post, 2 mm wall. Please check.
Two stays per straining post.
How we calculate
- Posts: one per corner/end; add posts so no stretch is longer than your max post spacing. Each post includes two stays.
- Y-standards: between each pair of posts, never more than the Y-standard spacing apart.
- Droppers: between posts and Y-standards, never more than the dropper spacing apart. Length is the first stock size taller than the fence. You choose the type.
- Galvanized binding wire 1.6 mm: 150 mm × wire lines × droppers.
- Galvanized binding wire 2 mm: 250 mm × wire lines × Y-standards.
- Fence wire: length × lines × (1 + waste%), at 2.24 mm; mass from round-wire steel density.
- Wire quantities: metres with kilograms below; metres and kilograms both rounded up.
