   "Mesh count is the number of openings per linear inch, counted from the centre of one wire to the same point 1 inch away. For square plain weave with wire diameter d (in) and count m, the opening is 1/m − d and the open area is (1 − m × d)² (as a fraction). The last two columns apply those two formulas to the printed mesh and wire diameter; they are computed here as a check and match the printed opening and open area to rounding in every row.",
   "A mesh count does not fix the wire: the same count is made with several wire diameters, which changes the opening and open area. Woven Wire Products lists 4 mesh with 0.047 in wire (0.203 in opening, 65.9% open) and with 0.063 in wire (0.187 in, 56.0%); Newark's mill-grade 4 × 4 uses 0.035 in wire (0.215 in, 74.0%). The two makers' tables are different grades (market grade against mill grade) and differ at nearly every count; state the wire diameter, not just the mesh, when you order.",
   "Mesh sizes are normally ordered as 'mesh × mesh × wire diameter' (for example 10 × 10 × 0.025). The Woven Wire Products stainless rows (14 to 20 mesh, 0.009 in wire) are the fine-wire, high-open-area version and carry T-304 and T-316 data sheets on the maker's site (not read). Wire diameters in mm are converted × 25.4 (computed) where the maker does not print them. Other weaves (twill, Dutch), rectangular mesh, space cloth and welded wire mesh are not covered here.",
   "Sieves and screens: US sieve numbers and mesh counts are close but not identical series; this page lists wire cloth only. Not to be confused with expanded metal (expanded-metal-standard-designations-swd-lwd), perforated sheet (perforated-metal-round-hole-standard-patterns) or the regenerator screens on this site. Gauge for wire diameters: awg-wire-gauge-table-astm-b258 and swg-standard-wire-gauge-table. No file: woven cloth is wire crossing over and under wire, and the crimp is not published as numbers."

 "sheet_text": "Woven wire mesh sizes: mesh count, wire diameter, opening and open area — 2 to 325 mesh (square weave, market and mill grade) — dimension sheet\nSource: Xem Studio, https://xemstudio.com/objects/woven-wire-mesh-sizes-opening-open-area/  (sheet CC BY 4.0)\nBasis: Woven Wire Products' market-grade table (39 rows, 2 to 325 mesh), its stainless 14 to 20 mesh sheets and Newark Wire Cloth's mill-grade table (29 rows, 2 to 60 mesh), with the open area recomputed; numbers only\nCatalog version: 2026-10-20\n\nSizes: see table below\n- Mesh count is the number of openings per linear inch, counted from the centre of one wire to the same point 1 inch away. For square plain weave with wire diameter d (in) and count m, the opening is 1/m − d and the open area is (1 − m × d)² (as a fraction). The last two columns apply those two formulas to the printed mesh and wire diameter; they are computed here as a check and match the printed opening and open area to rounding in every row.\n- A mesh count does not fix the wire: the same count is made with several wire diameters, which changes the opening and open area. Woven Wire Products lists 4 mesh with 0.047 in wire (0.203 in opening, 65.9% open) and with 0.063 in wire (0.187 in, 56.0%); Newark's mill-grade 4 × 4 uses 0.035 in wire (0.215 in, 74.0%). The two makers' tables are different grades (market grade against mill grade) and differ at nearly every count; state the wire diameter, not just the mesh, when you order.\n- Mesh sizes are normally ordered as 'mesh × mesh × wire diameter' (for example 10 × 10 × 0.025). The Woven Wire Products stainless rows (14 to 20 mesh, 0.009 in wire) are the fine-wire, high-open-area version and carry T-304 and T-316 data sheets on the maker's site (not read). Wire diameters in mm are converted × 25.4 (computed) where the maker does not print them. Other weaves (twill, Dutch), rectangular mesh, space cloth and welded wire mesh are not covered here.\n- Sieves and screens: US sieve numbers and mesh counts are close but not identical series; this page lists wire cloth only. Not to be confused with expanded metal (expanded-metal-standard-designations-swd-lwd), perforated sheet (perforated-metal-round-hole-standard-patterns) or the regenerator screens on this site. Gauge for wire diameters: awg-wire-gauge-table-astm-b258 and swg-standard-wire-gauge-table. No file: woven cloth is wire crossing over and under wire, and the crimp is not published as numbers.\n\nsource  mesh count  wire dia (in)  wire dia (mm)  opening (in)  opening (mm)  open area %

  {
   "q": "What is the opening of 10 mesh wire cloth?",
   "a": "0.075 in with 0.025 in wire (Woven Wire Products, 56.3% open) or 0.080 in with 0.020 in wire (Newark mill grade, 64.0% open): the opening is 1/10 − the wire diameter."
  },
  {
   "q": "How do I calculate open area of wire mesh?",
   "a": "(1 − mesh count × wire diameter in inches)² × 100. For 20 mesh with 0.016 in wire that is (1 − 0.32)² = 46.2%, which is what Woven Wire Products prints."
  },
  {
   "q": "What does mesh count mean?",
   "a": "Openings per linear inch, measured from wire centre to the same point one inch along. 100 mesh has 100 openings to the inch."
  },
  {
   "q": "Does the same mesh always have the same opening?",
   "a": "No. 4 mesh is 0.203 in open with 0.047 in wire and 0.187 in with 0.063 in wire (Woven Wire Products); the opening depends on the wire."
