What is GSM?

The thickness of the cloth

What does the acronyms stand for?

[-] Reverendender@sh.itjust.works 5 points 4 months ago

I misstated the definition a bit, although in real world terms a higher GSM does often manifest as a thicker cloth. GSM stands for grams per square meter. It measures how much fabric weighs in a given area. It is a weight rating, not a thickness rating.

Higher GSM means denser, heavier fabric. Lower GSM means lighter, more breathable fabric.

General guide:

120–140 GSM = lightweight (summer sheets, thin shirts)

150–170 GSM = medium weight (jersey sheets, linen duvet covers)

180–250 GSM = heavier weight (flannel, winter bedding)

GSM helps compare feel and durability across materials, but thickness will vary by fiber type.

Grams per square metre

Then shouldn't it be g/m^2 ?

I'm not going to speculate on what it should or could be. I'm just telling you what it is

Paper weight is also commonly expressed in gsm

Americans probably want in trucks per square football field. Anything but metric.
