Fence Material Calculator South Africa

Material quantity formula

Bays per run = ceil(run length ÷ specified maximum post-centre interval). Independent post positions = sum((bays + 1) × run count). Deduct verified shared endpoint duplicates and add separately scheduled extra posts.

How to measure fence runs and gate openings

Enter separate straight fenced runs between defined end, corner or gate-post positions, measured on the planned post-centre basis. Gate openings are excluded from these run lengths; do not subtract them again. Split at corners, gates and changes of system rather than entering one perimeter with a single total gate deduction. A repeat count means identical independent runs. Confirm the boundary, levels, access and layout before ordering. The tool does not locate a legal boundary or resolve a sloping site from a plan length.

Fence bays, posts and shared endpoints

For each straight run, bays = ceil(run length ÷ specified maximum post-centre interval), and independent post positions = bays + 1. The calculator divides that run into equal estimated bays; actual module and fixing details still govern. Independent runs count their own endpoints. If two endpoints use the very same physical post, deduct one duplicate; three runs sharing one post produce two duplicates. Enter only duplicates verified on the plan. A gate opening does not make its two gate posts one shared endpoint.

Gate posts, corners and additional posts

Count gate or corner posts already serving as run endpoints once, not again as additional posts. Use additional scheduled posts only for positions outside the calculated runs, such as separately detailed gate or bracing posts. Position count does not specify the post type: terminals, corners, line posts, gate supports and braces can differ. Post costs therefore use a separately quoted total for the actual post schedule rather than multiplying every position by one assumed standard-post price. No gate support, wind load or foundation design is generated.

Panel and palisade fence material calculator

Panel mode estimates one full panel per planned bay, followed by an explicitly entered spare allowance. The post-centre interval must correspond to the selected panel system, clamps and post geometry; it is not automatically the panel face width. A short final bay may require an approved cut, a special module or a revised layout. A quantity result does not establish that a panel can be cut or a connection adjusted. Palisade sections, welded panels and vinyl panel products have different details, so use the exact system specification.

Chain link and wire mesh rolls

Roll mode rounds each run independently using the entered usable coverage length of one roll and the chosen infill allowance. Repeat counts multiply those per-run purchases. No cross-run offcut reuse is assumed. Check roll height, mesh aperture, wire diameter, coating, joining, tensioning and termination requirements for the intended use. Usable coverage can differ from nominal roll length. This mode does not infer strainers, ties, rails or braces. Optional horizontal-wire take-off is a separate linear quantity, not a count of wire reels or an electric fence design.

Wood and vinyl picket fence material calculator

Picket mode uses the estimated equal bay clear width after subtracting the entered total post/fitting-width allowance per bay. It places uncut pickets with equal gaps at both edges and between pickets, all no greater than the entered maximum. Count per bay = max(1, ceil((clear width − maximum gap)/(picket width + maximum gap))). The result also checks that the uncut pickets fit. An impossible zero-gap or narrow-bay combination is rejected rather than hidden. Actual bay clearances, openings, fixings and allowable layout must be checked before ordering.

Footing concrete and horizontal wire

Optional concrete is a take-off for the entered count of posts receiving one already specified net footing volume. It does not assign that volume to every post or design hole dimensions. Net concrete litres must account for the actual occupied post volume and footing detail. A separate concrete allowance is explicit. Optional horizontal wire is fenced run length × entered strand count, with its own allowance. Terminations, tensioning and reel-cutting plans remain separate; gate gaps are not automatically bridged by that quantity.

Fence material prices and supplier comparisons

Infill prices use purchased full panels, mesh rolls or picket packs according to the selected mode. Enter separate quoted totals for the actual post types, gate assemblies, optional wire, other rails or fixings, installation and delivery. Concrete pricing uses its allowance-adjusted scheduled m³. Use one VAT basis and avoid repeating included components. Zero cost lines remain unpriced, and no current supplier prices or nearby stock are invented. Compare like specifications and complete scope when requesting quotes from a fence material supplier.

Which fence material is best or cheapest?

The appropriate material depends on privacy, security, exposure, maintenance, appearance and the purpose of the barrier. Timber, coated steel, chain link, palisade, vinyl and other plastic fencing have different product and support requirements. Privacy infill can increase wind loading; a visual screen is not proof of security performance. For a dog fence, consider the particular animal, openings, climbing and digging risks without relying on one universal best material. A silt fence is an erosion-control product, not an interchangeable security fence. Inspect used materials for condition and compatibility.

Electric, security and pool fencing

Use a competent specialist for electric fencing, including the energizer, earthing, clearances, signs, gate details and applicable installation certification. The optional strand length does not specify or approve any of those components. Pool barriers need the applicable national and local requirements checked for the complete barrier and gate arrangement. Ordinary garden or security fencing is not automatically a compliant pool barrier. This estimator provides quantities and entered costs only; it does not certify electrical, pool, anti-climb or structural performance.
