Mesh count alone is insufficient. Use the finished wire diameter and the correct count per inch or centimetre.

Wire Mesh Weight Calculator
Estimate single-layer woven mesh weight from wire geometry, or sum confirmed layer unit-area masses for multi-layer filter mesh parts.
Quick definition: theoretical mesh weight is the metal volume of both wire directions multiplied by density; actual weight changes with weaving crimp, wire tolerance and edge condition.

Formula used
kg/m² = 2 × wires per metre × wire cross-section × density × (1 + crimp %)How to use the calculator
Select density
Choose the alloy family or enter the density stated on the material certificate for a closer estimate.
Confirm by weighing
For orders and freight, verify an approved sample because crimp, tolerance and trimmed edges affect actual mass.
Formula and applicability
The calculator treats the mesh as two perpendicular wire systems. Wire count per metre is converted from mesh count; each wire uses a circular cross-section of πd²/4.
Crimp allowance increases the straight-line wire length to approximate the over-and-under weaving path.
The single-layer geometry method suits square plain or twill weave. It is not suitable for Dutch weave, reverse Dutch weave, multi-ply sintered mesh, knitted wire mesh, expanded metal or welded mesh.
For Dutch weave, warp and weft counts, diameters and packing geometry must be calculated separately.
Why the common shortcut can differ
| Method | Inputs | Strength | Limitation |
|---|---|---|---|
| Mesh × d² ÷ 2 | Mesh, diameter | Fast steel estimate | Assumes a fixed density and coefficient |
| Density-based formula | Mesh, diameter, density | Works across materials | Still needs crimp adjustment |
| Sample weighing | Known area and scale | Includes real construction | Requires a representative sample |
Multi-Layer Filter Mesh Weight Calculator
Sum confirmed unit-area masses for each layer group, then calculate net mesh mass for common rectangular, disc or ring parts.
Enter measured or separately verified mass per area for each layer. This section does not derive Dutch-weave or sintered composite mass from mesh count. All layers share the entered footprint. Defaults are examples, not a recommended construction.

Layer mass balance
Combined unit-area mass = Σ(layer mass/area × repeats). Net mass per part = footprint × combined unit-area mass. Batch = part mass × part quantity.
Excludes frames, weld additions, end caps, bonding media, contamination and packaging. Final sintered part data may differ from the sum of input sheets; use verified finished-product mass for acceptance.
Example: 0.5 kg/m² × 1 ply plus 1.2 kg/m² × 2 plies gives 2.9 kg/m². A 100 × 100 mm part contains 0.029 kg net mesh; 10 parts contain 0.29 kg.
For different layer footprints, trimmed areas or components, calculate each separately and sum their net masses. This mass balance does not predict filtration precision, efficiency or pressure drop.
Frequently asked questions
How do you calculate wire mesh weight?
Calculate the total length of warp and weft wires per square metre, multiply by circular wire cross-section and material density, then apply any crimp allowance.
Why is wire diameter required?
Wire mass changes with the square of diameter. A small diameter difference can materially change the estimated weight.
Does mesh count equal aperture?
No. Clear aperture is pitch minus wire diameter, so two meshes with the same count can have different openings and weights.
What crimp allowance should I use?
Use measured production data when available. A small preliminary allowance may be used for square woven mesh, but the real value depends on weave and wire stiffness.
Can this calculator be used for Dutch weave?
The single-layer geometry mode cannot derive Dutch-weave mass. The multi-layer section can sum independently verified unit-area masses, including Dutch-weave layers, without inferring them from mesh count.
Can the result be used for final purchasing weight?
Use it for planning only. Confirm final order and freight weight with production specifications or a measured sample.
Multi-layer weight questions
Does the multi-layer section predict sintered filter performance?
No. It sums entered layer masses over a common footprint. It does not predict micron rating, porosity, pressure drop or final manufacturing mass changes. Frames, bonding media, weld additions and packaging require separate calculations.
Plan roll area and rectangular cuts with the mesh roll length and cutting calculator. For solid round wire use the metal wire weight and length calculator.
