Fabric GSM / Mass per Unit Area: What to Write in a Cloth Brief
Write cloth mass as a number—for example grams per square metre (g/m²) or ounces per square yard (oz/yd²)—not as “medium weight.” ASTM D3776 is the ASTM standard titled Standard Test Methods for Mass Per Unit Area (Weight) of Fabric (ASTM D3776). Citing D3776 tells mills and factories which family of mass-per-unit-area methods you mean when you ask for a measured weight.
Shi Yuan does not invent typical suit GSM ranges here. We confirm the fabric you name before the sample clock starts.
What belongs in a cloth brief?
| Field | What to write |
|---|---|
| Target mass | Number + unit (g/m² or oz/yd²), not “medium / light / heavy” |
| Method reference | ASTM D3776 (or the mill’s named equivalent) when you require a test report |
| Cloth ID | Mill name, quality code, colour, and lot if known |
| Supply path | Customer-supplied, stock, or mill indent |
| Factory gate | Fabric confirmed before sample 7–14 day clock |
Target mass: number + unit (g/m² or oz/yd²), not “medium / light / heavy”
Method reference: ASTM D3776 (or the mill’s named equivalent) when you require a test report
Cloth ID: mill name, quality code, colour, and lot if known

Factory gate: fabric confirmed before sample 7–14 day clock
Why vague weight words fail private label
“Medium-weight wool” can mean different grams on two mills. Bulk from 50 then drifts from the sealed sample even when construction (fused / half / full canvas) was named correctly.
Timing at Shi Yuan
Sample 7–14 days after measurements and fabric are confirmed. Production 14–21 days after sealed-sample approval. MTM from 1; bulk OEM from 50.
"We start the sample clock only after fabric is confirmed. Write mass as a number with a unit—not as medium weight—so bulk from 50 can match the sealed sample." — Shi Yuan Suit Factory (statement built from published factory policy)
FAQ
What is ASTM D3776?
ASTM D3776 is Standard Test Methods for Mass Per Unit Area (Weight) of Fabric. Use it when you want cloth weight stated as a measured mass per unit area rather than a vague adjective.
Should a cloth brief say “medium weight”?
No. Write a target number with a unit (g/m² or oz/yd²) and name the cloth ID. Confirm fabric before Shi Yuan starts the 7–14 day sample clock.
Does Shi Yuan publish typical suit GSM ranges?
No invented ranges in this briefing. We match make to the fabric and mass you confirm in writing for the sample and for bulk from 50.
