Woven Wire Mesh Calculator

How to use this result

Use this when mesh count and wire diameter are known. The mass result is a geometry-based estimate and does not include every crimp or finishing effect.

What to confirm

Submit the result with the application, dimensions, quantity and operating conditions if you want a human specification check.

Use the nominal relationship correctly

Mesh count is openings per linear inch, not the number of wires. Enter nominal round-wire diameter in the selected unit. The tool first finds pitch, subtracts wire diameter to obtain clear aperture, and then calculates projected open area. The mass value assumes straight wire length in two orthogonal directions; weave crimp and finishing can change delivered mass.

Worked interpretation

A 10 mesh construction with 0.56 mm wire has 2.54 mm pitch, 1.98 mm nominal aperture and about 60.8% geometric open area. This agrees with the published geometry formula and provides a useful calculator validation point.

Before you put the result on a purchase order

Confirm the construction and weave, nominal geometry, material grade, finished width and length, edge treatment, quantity, tolerance basis and inspection documents. State whether values are nominal, minimum or maximum. For a replacement part, add a drawing or labeled photographs and explain the observed failure mode.

Common mistakes to avoid

• Mixing millimetres, micrometres and inches without recording the conversion.
• Assuming a calculated combination is automatically stocked or manufacturable.
• Using nominal open area as filtration efficiency, pressure drop or structural capacity.
• Leaving material certificates, tolerances, edges and finished dimensions until after quotation.

Save the input and output with the RFQ so another reviewer can reproduce the calculation. If the duty is critical, use a sample, drawing review or process test before releasing production.
