チェーンリンクメッシュ計算ツール

チェーンリンクのメッシュで区間を覆うのに何巻必要か、残りの切り端が何フィートか、継ぎ目がいくつできるかを、式を表示しながら求めます。

必要なメッシュの巻数

寸法を入力すると、入力に合わせて結果が更新されます。

概要

チェーンリンクのメッシュは、長さを一定の高さで測った巻きとして売られます。1 巻は 50 フィートが一般的で、ときに 100 フィートもあります。1 巻より長い区間では巻どうしに継ぎ目が必要で、最後の余りは切り端として残ります。この計算ツールは、あなたの延長と巻の大きさから、その 3 つの数字すべてを求めます。

メッシュの幅 (高さ) は、フェンスの高さに合う巻を選ぶことで合わせます。必要な量を決めるのは巻の長さと区間の長さの 2 つなので、この計算ツールはその 2 つだけを尋ねます。

前提条件

  • The run length is the straight fence span to be covered, not the whole perimeter.
  • Roll length options are the common 50 and 100 foot sizes.
  • A splice is counted at every roll-to-roll join, which is rolls needed minus one.

よくある間違い

  • おおよその数で当て推量すること (「2 巻あれば足りるだろう」) ではなく、区間を巻の長さで割って余りを処理すること。
  • 最初の巻を含むすべての接合部に継ぎ目を数えること。1 巻だけの区間には継ぎ目がまったくありません。
  • 1 巻より長い区間では、残った切り端も実際に代金を払う一枚として残ることを忘れること。

詳細なガイド

購入ガイド

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.

よくある質問

チェーンリンクのメッシュは何巻必要ですか

区間の長さを巻の長さで割って切り上げます。50 フィート巻で 150 フィートの区間なら 3 巻です。完全な 2 巻と 50 フィートの 1 枚で、巻どうしに 2 つの継ぎ目ができます。

区間が割り切れないときの切り端は何ですか

完全な巻を差し引いたあとの余りです。その余りも実際の巻から切り出す必要があるので、巻き数は切り上げてそれを賄うように数えます。

チェーンリンクのフェンスにはいくつ継ぎ目ができますか

巻の数より 1 つ少ない数です。巻どうしの接合が 1 か所が継ぎ目で、1 巻だけの区間には接合がないからです。50 フィート巻で 150 フィートの区間なら継ぎ目は 2 か所です。

メッシュの巻はフェンスの高さで買うべきですか

はい。メッシュは高さの規格が決まっており、変わるのは区間の長さです。巻の高さをフェンスの高さ (たとえば 5 フィートや 6 フィート) に合わせ、巻数は区間の長さだけで決めてください。

継ぎ目ではメッシュをどのくらい重ねますか

メーカーが重ね幅を指定していて、通常はメッシュ 1 マス分です。張り詰めた線が両方の枚を通せるようにするためです。できるだけ切り端どうしが支柱で接するように巻の配置を計画してください。

住宅のフェンスにはどの番手のメッシュを選べばよいですか

住宅のメッシュは一般に 11.5 から 9 番手です。太い (番手数の少ない) メッシュほど高く、損傷に強く耐えます。巻数と継ぎ目の計算は、番手によらず同じです。

門の部分はメッシュの枚数に影響しますか

はい、メッシュで覆うのは門と端部の開口部を除いたスパンです。門は自分のメッシュを持つからです。フェンス全体の計算ツールと同じように、この計算ツールを使う前に門の幅を延長から差し引いてください。

チェーンリンクのメッシュは 1 巻いくらですか

価格は高さ、番手、コーティング、地域によって変わるので、全国一律の数字は誤解を招きます。使う予定の巻サイズについて地元の販売元に確認してください。その上で、フェンス費用の計算ツールが区間に対する合計を出せます。
