The Weight Map: Which Knit Goes Where, from 60 to 500 g/m²
Weight is the fastest indicator of what a knit is for, and Fersan’s ten families line up on a single axis from 60 to 500 g/m². The light band — mesh and jersey — goes to linings and summer tops; the middle band, piqué and interlock, to polos and dresses; the upper band, French terry, rib and fleece, to sweatshirts, collar-and-cuff trims and outer layers. At the same weight, different structures give different hand: weight alone is not a quality measure.

Weight (g/m²) is a knit’s mass per square metre and the fastest indicator of which product it suits. Fersan’s ten families line up on a single 60–500 g/m² axis; the map below summarises which band matches which product.
From band to product
| g/m² band | Typical family | Typical product |
|---|---|---|
| 70–130 | Air mesh / net | Lining, panel, light jersey |
| 80–200 | Single jersey / microfiber | Tees, tanks, innerwear |
| 120–280 | Piqué / bird’s-eye | Polos, performance tees |
| 80–260 | Interlock | Polos, jerseys, babywear |
| 150–320 | French terry | Sweatshirts, hoodies |
| 270–360 | Ponte / double-knit | Structured dresses, skirts, jackets |
| 200–350 | Three-thread fleece | Winter sweatshirts, joggers |
| 180–400 | Polar fleece | Winter outerwear, lining, blankets |
| 60–500 | Rib · raschel (warp knit) | Collars, cuffs, trims, ribbed tops; net, power net, decorative panels |
The same weight is not always the same hand
Weight alone does not tell all: single bed (single jersey) and double bed (interlock) feel very different at the same 200 g/m²; yarn fineness (denier), knit density and finishing also decide. So read the values as 'typical ranges', not exact recipes.
Selection tips
- For light and cool, start at the low band (mesh, light single jersey).
- For coverage and durability, move to the mid-upper band (interlock, French terry).
- For warmth and upright stance, the top band (three-thread, ponte, polar).
- Exact weight, composition and width are set to order — confirm with a sample.
Frequently asked questions
Which weight goes to which product?
Roughly: mesh and light jersey 70–150 g/m² (summer, lining); tees and innerwear 120–200; polo/piqué and rib 165–300; sweatshirt/hoodie two- and three-thread 250–350 g/m². The exact band depends on the fabric family.
Does the same weight always give the same hand?
No. At the same GSM, structure, yarn and finish change the hand; for example a 200 g/m² interlock and a piqué of the same weight differ in stiffness, opacity and stretch.
