Calculateur de grillage à mailles

The chain link fabric calculator answers a narrower question than the full chain link fence calculator: given a run length and a roll length, commonly 50 or sometimes 100 feet, how many rolls does the job need, what is the leftover cut piece, and how many splices join the rolls together. Posts, rail and concrete are a separate calculation handled by the full fence calculator and by the fence post calculator; this tool exists because fabric is bought and billed by the roll, and rounding that number wrong either leaves a gap in the run or wastes a whole extra roll.

A splice happens at every roll to roll join, which is always one fewer than the number of rolls, since a single roll run has no joins at all. A 150 foot run covered by 50 foot rolls needs three rolls and two splices, with the third roll cut short rather than used in full. Fabric gauge, commonly 11.5 down to 9 gauge for residential work, does not change this math at all: a heavier gauge roll of the same length still counts the same way, it simply costs more per roll and resists damage better. The chain link fence installation guide covers how much overlap a proper splice needs and why planning cut ends to land at a post makes the stretch and lace step easier.

Run length for this calculator should exclude gate openings and any section that will not carry fabric, since gates are fitted with their own panel rather than drawing from the perimeter roll count, the same exclusion the full fence calculator applies. Measuring an irregular lot accurately matters here more than it might seem, since an error of even a few feet can push the roll count up by a whole roll once it crosses a boundary; the fence perimeter calculator is the right tool for getting that total length right on a lot with corners and offsets before it goes into the fabric math. Post spacing is a related but separate decision from fabric length, and the how far apart should fence posts be guide covers the common 10 foot chain link interval if posts have not been planned yet.

Fabric price varies enough by height, gauge, coating and region that no single national number is reliable, so this calculator deliberately stops at roll, cut piece and splice counts rather than guessing a price; feed those quantities, along with the post and concrete totals, into the fence cost calculator using your own supplier's roll price for a total that actually matches your job. The wood vs chain link fence cost and chain link cost per foot guides give a sense of where chain link typically lands before you have a quote in hand. Concrete for the posts that anchor the fabric is sized separately by the fence post concrete calculator, and the metal fence calculators hub is the place to compare chain link against aluminum and ornamental steel options for the same run.

Buying slightly more fabric than the bare minimum is common practice, since a cut piece at the end of a run is rarely a perfectly reusable length for a future repair, and a short remnant from one job is often too small to patch a different section later. Coating also factors into the roll decision even though it does not change the splice math: galvanized fabric is the standard residential choice, while vinyl-coated fabric adds a colored finish and a modest amount of corrosion resistance at a higher price per roll. Whichever coating is chosen, keep the roll height matched to the fence height decided elsewhere in the project, since fabric is not sold in a way that can be trimmed shorter without losing the finished top edge, and a mismatched roll height is one of the more expensive mistakes to discover after the fabric has already been delivered and cut.

Tension wire, strung along the bottom of the fabric rather than through it, is a common companion to a chain link run and is sold separately from the fabric roll itself, so it is worth accounting for alongside the roll and splice totals this calculator returns rather than assuming it comes included. Top rail serves a similar supporting role along the top edge, and while both are usually priced and ordered by length rather than by roll, the same run length used for the fabric calculation is also the number to use when ordering rail and tension wire, which keeps every component of the job tied to one consistent measurement instead of several slightly different ones. Checking the fabric height against the post height before ordering is also worth doing explicitly, since fabric is typically sold a few inches shorter than the nominal post height to leave room above and below the mesh, and assuming the two numbers match exactly is a common source of a fence that looks shorter than planned once it is installed and stretched.
