Replacing universal light, mid, and heavyweight charts with comparable fabric evidence and product-specific decisions
What the source establishes.
The guide cites current ASTM and ISO sources for fabric mass per unit area, woven-fabric mass, sampling, conditioning, stiffness, and thickness plus the NIST conversion table; it separates method-defined measurements from product-defined targets, tolerances, and suitability.
The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
What this record does not prove.
The record does not provide universal fabric-weight classes, garment recommendations, test values, targets, tolerances, sampling counts, lot acceptance, drape or performance conclusions, compliance, or a substitute for representative swatches, product trials, and qualified textile, testing, product, quality, safety, sourcing, and compliance review.
A reachable official source can verify identity, stated scope, and access. It cannot silently become an audit of workmanship, delivery, labor conditions, or suitability for your project.
A record that can age in public.
New checks are appended rather than replacing earlier states. The latest source review is due by July 16, 2027.
