What Yarn Count Means
Yarn count describes the fineness of the yarn. In the English cotton system, a higher number means a finer yarn: 40s is finer and lighter than 21s. Finer yarn gives a smoother, softer surface; coarser yarn gives a denser, warmer fabric.
Yarn count alone does not fix the fabric. It works together with knit gauge and fiber to set the final hand-feel and weight.
What Knit Gauge Means (GG)
| Gauge | Meaning | Typical use |
|---|---|---|
| 7 GG | Coarse, chunky knit | Coarse, chunky knit |
| 12 GG | Mid-weight knit | Mid-weight knit |
| 16-18 GG | Fine, lightweight knit | Fine, lightweight knit |
Gauge is the number of needles per inch on the knitting machine. Higher gauge means finer, tighter stitches and a lighter fabric.
Yarn Count vs Fabric Weight (GSM)
- Finer yarn (higher count) tends toward lower GSM.
- But gauge and loop length also change GSM.
- Always specify GSM as the final target, yarn count as the means.
How Yarn Count Affects Feel & Cost
- Finer yarn: softer drape, pricier, more delicate.
- Coarser yarn: sturdiest, warmest, most economical.
- Blended counts balance feel and budget.
If you only know the garment you like, send a reference sample. We measure its yarn count and gauge and match it — you do not need to be a textile engineer.
Specifying Yarn & Gauge in a Tech Pack
- State target GSM as the primary spec.
- Add yarn count and fiber composition.
- Note gauge (GG) for knit constructions.
- Attach a physical reference if unsure.
