FAQ
How do you calculate wire mesh weight per square metre?
For square woven mesh, weight (kg/m²) ≈ 0.0618 × mesh count × wire diameter² × material density, where mesh count is wires per inch, wire diameter is in mm and density is in g/cm³. This sums the warp and weft wire mass in one square metre; it ignores wire crimp, which adds roughly 2–5% on fine meshes.
Does material affect wire mesh weight?
Yes. Weight scales directly with density: stainless 316 (7.98) and 304 (7.93) are close to carbon/galvanised steel (7.85), while aluminium (2.70) is about a third of the weight and brass/copper are heavier. Select the material in the calculator to apply the correct density.
What is roll weight?
Roll weight = weight per m² × roll width (m) × roll length (m). Enter the roll dimensions to estimate shipping weight for a full roll, useful for freight and quote calculations.
What this calculator does — and why mesh weight matters
Wire mesh is bought, shipped and freighted by weight, not by the metre. A roll that looks identical on a spec sheet can weigh very different amounts once you change the material, the wire diameter or the mesh count — and getting that figure wrong throws off your budgeting, your freight quotes and your container loading. The same 10-mesh cloth woven from stainless steel weighs almost six times as much as the aluminium version, so a guess based on "area" alone is rarely safe.
This free calculator gives you an instant, transparent estimate of areal weight (kg/m²) and full roll weight from three inputs: mesh count, wire diameter and material. It uses the standard square-woven wire-cloth formula and published material densities, so the result is reproducible and easy to check by hand. Use it to sanity-check a supplier quote, plan a shipment, or compare two material options before you commit. For converting between mesh, microns and inches first, see the spec converter; to narrow down a mesh by application, try the mesh selector.
Worked examples
Example 1 — 10 mesh, 0.9 mm wire, mild steel
Start with the formula: weight (kg/m²) = 0.0618 × mesh count × wire diameter² × density. Plug in 10 mesh, 0.9 mm wire and a mild/galvanised steel density of 7.85 g/cm³: 0.0618 × 10 × (0.9 × 0.9) × 7.85 = 0.0618 × 10 × 0.81 × 7.85. That works out to 3.93 kg/m². So a single square metre of this cloth weighs just under four kilograms.
Example 2 — the SAME mesh in aluminium
Keep everything identical — 10 mesh, 0.9 mm wire — but switch the material to aluminium (density 2.70 g/cm³): 0.0618 × 10 × 0.81 × 2.70 = 1.35 kg/m². Same opening, same wire, yet the cloth now weighs about a third of the steel version. Material choice — not the weave — is the single biggest lever on shipped weight, which is why it pays to compare options before ordering. The relationship is exactly the density ratio: 2.70 / 7.85 = 0.34, and 3.93 × 0.34 = 1.35.
Example 3 — full roll weight, 30 mesh, 0.30 mm wire, stainless 304
First the areal weight: 0.0618 × 30 × (0.30 × 0.30) × 7.93 = 0.0618 × 30 × 0.09 × 7.93 = 1.32 kg/m² (1.323 before rounding). Now scale to a roll measuring 1.2 m wide × 30 m long = 36 m² of cloth. Multiply: 1.323 × 36 = 47.6 kg per roll. That is the indicative cloth weight you would use for freight planning — actual packed weight will be slightly higher once core, packaging and any selvage are included.
Wire mesh material density reference
Areal weight scales directly with material density, so the density figure you feed the formula matters more than any other single input. The table below lists the densities used by this calculator, each shown relative to mild steel (density ÷ 7.85) so you can see at a glance how much lighter or heavier a given material will make the same cloth. These are standard, widely published values for the common alloys used in woven wire mesh.
| Material | Density (g/cm³) | Relative weight vs steel | Typical use |
|---|---|---|---|
| Mild / galvanised steel | 7.85 | 1.00× | General-purpose screening, fencing, aggregate and construction mesh; galvanising adds corrosion resistance at low cost. |
| Stainless steel 304 | 7.93 | 1.01× | Filtration, food processing and architecture where good corrosion resistance and hygiene are needed. |
| Stainless steel 316 | 7.98 | 1.02× | Marine, chemical and high-chloride environments needing extra corrosion and pitting resistance. See ss304 vs ss316. |
| Aluminium | 2.70 | 0.34× | Lightweight insect screens, ventilation and architectural panels where weight and easy handling matter. |
| Brass | 8.50 | 1.08× | Decorative screens, fine filtration and acoustic mesh; non-sparking and corrosion-resistant in many media. |
| Copper | 8.96 | 1.14× | EMI/RF shielding, decorative and antimicrobial applications; the heaviest of the common mesh materials. |
Densities are standard published values for the base alloy. Real coil weight can differ slightly from a density-based estimate because of wire tolerance, coating (e.g. galvanising or PVC), selvage and edge treatment. To compare the two grades in detail, see ss304 vs ss316.
Who uses this calculator — industries and roles
Anyone who plans, prices or ships woven wire mesh runs into the weight question. Importers and distributors use it to estimate freight and check whether a quoted roll weight looks right; procurement and estimators use it to build accurate material budgets; logistics and shipping teams use it for container loading and pallet planning. On the technical side, design engineers and specifiers use areal weight to compare material options and confirm a structure can carry the load. The same calculation matters across filtration, mining and aggregates, food processing, chemical processing, water treatment, architecture, agriculture and general construction — wherever mesh is bought by weight and shipped in volume. For a fuller breakdown of what drives total landed cost, see the wire mesh cost guide.
Why you can trust this calculator
We are an independent wire mesh reference site with no product to sell, so this tool is built for accuracy and transparency rather than to push any material or supplier. The formula and densities are shown openly so you can reproduce every result by hand, and every figure is clearly labelled as an indicative estimate.
- The full formula is shown on the page — nothing is hidden, and you can check any result with a calculator.
- Material densities are standard, widely published values for each alloy.
- Results are indicative estimates of cloth weight, not guaranteed packed or invoiced weights.
- Real coil weight varies with wire tolerance, coating, selvage, edge treatment and packing, so we tell you that rather than imply false precision.
- Neutral and independent: we never recommend a specific brand, factory or supplier.
Key terms, defined
- Areal weight (kg/m²)
- The weight of one square metre of the woven cloth. It is the core output of this calculator and the figure you scale up to get roll or shipment weight.
- Wire diameter
- The thickness of the individual wire used to weave the mesh, measured in millimetres. Because it is squared in the formula, small changes in diameter have a large effect on weight.
- Density
- The mass per unit volume of the mesh material, in grams per cubic centimetre. It is set by the alloy you choose and scales weight directly — heavier material, heavier cloth.
- Roll / coil weight
- The total weight of a full roll, found by multiplying areal weight by the roll area (width × length). It is the figure used for freight, pallet and container planning.
Frequently asked questions
How do you calculate wire mesh weight per square metre?
For square woven mesh, weight (kg/m²) ≈ 0.0618 × mesh count × wire diameter² × material density, where mesh count is wires per inch, wire diameter is in mm and density is in g/cm³. This sums the warp and weft wire mass in one square metre; it ignores wire crimp, which adds roughly 2–5% on fine meshes.
Does material affect wire mesh weight?
Yes. Weight scales directly with density: stainless 316 (7.98) and 304 (7.93) are close to carbon/galvanised steel (7.85), while aluminium (2.70) is about a third of the weight and brass/copper are heavier. Select the material in the calculator to apply the correct density.
What is roll weight?
Roll weight = weight per m² × roll width (m) × roll length (m). Enter the roll dimensions to estimate shipping weight for a full roll, useful for freight and quote calculations.
How do I estimate the weight of a full roll?
First find the areal weight in kg/m² using mesh count, wire diameter and material density. Then multiply by the roll area in square metres, which is width × length. For example, a cloth at 1.32 kg/m² on a 1.2 m × 30 m roll (36 m²) gives about 47.6 kg of cloth before packaging.
Why is stainless mesh heavier than aluminium mesh?
Weight scales directly with material density. Stainless 304 has a density of about 7.93 g/cm³ while aluminium is only 2.70 g/cm³ — roughly a third as dense. So an identical mesh count and wire diameter in stainless weighs nearly three times as much as the same cloth in aluminium.
Does the calculator include the edge or selvage weight?
No. The result is the indicative weight of the plain woven cloth based on mesh count, wire diameter and density. It does not add core, packaging, coating, or any reinforced edge or selvage. Treat the figure as an estimate for planning and add a small allowance for real packed weight.
