Wire mesh tolerances vary by material, weave type, and manufacturer, but you can generally expect small deviations in wire diameter, opening size, and overall dimensions.

For most standard woven or welded mesh, common tolerances are around ±5% to ±10% for wire diameter and opening size. Woven mesh tends to be tighter and more consistent, while expanded or specialty meshes may have wider tolerances. If you need precise dimensions, ask the supplier for the specific tolerance chart for that mesh type.
