170 Mesh to Micron – Opening Size in µm & mm
170 mesh ≈ 88 µm
A US standard 170 mesh sieve has openings of about 88 µm (0.088 mm, 0.0035 in).
Step by step
- Mesh 170 means about 170 openings per linear inch.
- Opening size depends on wire thickness, so it is read from the standard sieve series (ASTM E11).
- 170 mesh ≈ 88 µm.
170 mesh is a fine screen for silt, pigments, fine powders and filtration.

How it works
Mesh number counts the openings per linear inch of a woven screen. Because the wire takes up space, the opening is smaller than 25.4 mm divided by the mesh count, and different wire gauges give different openings — so standard sieve series fix the exact opening for each number. Values here follow the US standard series; Tyler mesh numbers are close but not identical.

Frequently asked questions
What is 170 mesh in microns?
About 88 µm.
What is 170 mesh in mm?
0.088 mm.
Is higher mesh finer?
Yes — more openings per inch means smaller openings.
What is the difference between US and Tyler mesh?
They are two standard series with nearly the same openings; the numbers differ slightly for some sizes.
