What Is GSM in Clothing?
And Why It Defines
Your Product.
GSM is the single most important spec on any garment. It tells you how heavy the fabric is, how it drapes, how it holds up over time, and what it signals to the customer the moment they pick it up.
GSM stands for grams per square meter.
It measures how much a fabric weighs per unit of area. The higher the number, the denser and heavier the fabric. A 480 GSM hoodie has more than three times the fabric mass of a 150 GSM tee.
Weight affects everything: how the garment feels in hand, how it drapes on the body, how well it holds a print, how it survives repeated washing, and what price point it can credibly occupy. Most brands discover this too late, after the first reorder, when the product no longer feels like what they approved.
The Full GSM Spectrum
From fast fashion basics to premium heavyweight garments — and where each level fits.
Why 300 GSM Is the Minimum for a Premium T-Shirt
Most blank t-shirts sit between 160 and 220 GSM. At 300 GSM, the experience is different. The fabric has real structure. It holds its shape across washes, holds graphics without distortion, and communicates quality the moment someone touches it.
This is not about warmth or thickness for its own sake. It is about what the fabric signals. A 300 GSM t-shirt feels like a considered product. A 160 GSM tee feels like a promotional item.
Why 480 GSM French Terry Defines the Premium Hoodie
Most hoodies sit between 280 and 380 GSM. At 480 GSM French Terry, the experience is different. Real weight in hand. A loopback interior that holds its form across seasons. A fit that drapes with volume rather than collapsing.
This weight is not about warmth. It is about presence. It is why brands use our hoodies as hero pieces — the kind of garment a customer remembers and comes back for.
