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

Wire Mesh Weight Calculator
Estimate woven wire mesh weight per square metre and total sheet or roll weight from mesh count, wire diameter, material density, dimensions and crimp allowance.
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.
This 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 |
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?
No. Dutch weaves use different warp and weft diameters, counts and packed openings, requiring a separate construction-specific calculation.
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.
