How should I choose stocking denier (D)?

Denier (D) is a unit for the thickness of the yarn — the higher the number, the thicker, more opaque, and heavier the yarn.

20D–30D are sheer, thin types suited to spring/summer and a natural look. 40D–80D are a medium weight that is only mildly sheer and works across all seasons. 100D–150D are opaque with some warmth for autumn/winter, while 200D and above are the thick, brushed/tights-type constructions for deep winter warmth.

Even at the same denier, the fit and stretch differ depending on the knitting method and the yarn type (the nylon / spandex blend ratio). So it is important to look at the material composition and knitting quality, not just the denier number.

GAMSUNGTEX offers a full denier lineup from 20D / 30D stretch types up to 150M / 230M / 300M high-gauge constructions, all under in-house vertical production (knitting, dyeing, finishing, packaging).
