How to choose GSM: what the number means and what it does not
Weight is the most-discussed and least self-sufficient number in a fabric specification. The same g/m² can describe two completely different cloths.

Weight is the most-discussed and least self-sufficient number in a fabric specification. The same g/m² can describe two completely different cloths.

Weight must be measured after conditioning and relaxation. A reading taken straight off the stenter differs from one taken days later. A GSM figure without its conditioning method cannot be compared.
Cost per kilo means nothing without usable width. At the same weight, a narrower fabric means higher consumption per garment. Marker efficiency is the product of both.
A target weight is a range, not a single number. Put a tolerance such as ±5% and the measurement method in writing before the order.
