What Yarn Count Actually Measures

Yarn count is a measure of fineness, not of quality. In the English cotton count (Ne) used across the trade, the number is how many 840-yard lengths of yarn make up one pound. So a higher number means a finer yarn, not a better garment:

Count Yarn Typical use Hand-feel
10s–21s Coarse Fleece back, heavy loopback, thick hoodies Thick, dry, built for warmth
26s–32s Medium Sweatshirt face, mid-weight tees Balanced — soft with some body
32s–40s Fine Retail tees, print-heavy styles Smooth, soft, holds fine detail
50s and above Very fine Lightweight premium knits Silky and thin — less durable at the same weight

Two garments can carry the same count and feel completely different, because count only describes the yarn — not the fabric weight, the stitch, or the fibre.

Single Yarn vs Double Yarn

This matters more than the count itself, and it is the detail most spec sheets leave out. A single yarn is one strand twisted. A double yarn is two singles twisted together — written as 40s/2, or just 40s double.

What double yarn buys you:

  • A more even surface — the twist evens out the thick and thin places, which is what makes a print look clean.
  • Higher strength at the same weight, so the garment keeps its shape through washing.
  • Less pilling, because loose fibre ends are bound into the twist instead of working free.
40s single is not 40s double. The count is identical on paper and the fabrics feel nothing alike. If a quote looks unusually cheap for a 40s tee, ask whether it is single or double before anything else.

How Count Changes Weight, Feel and Cost

  • Finer yarn gives a smoother surface at the same fabric weight, which is why print-heavy styles use 32s–40s.
  • Coarser yarn gives bulk and warmth more cheaply, which is why fleece backs sit at 10s–21s.
  • Finer yarn costs more per kilogram: more spinning passes, more fibre wastage, and a slower loom.
  • Long-staple cotton matters as much as count. A 32s long-staple yarn can outlast a 40s short-staple one.

Which Count for Which Product

These are the ranges we would quote for each product type. They are starting points, not rules — the stitch and the fibre move the result as much as the count does:

Product Fabric weight Count we would use Why
Premium retail tee 180–220 gsm 32s–40s double Smooth surface, holds fine print detail
Heavy tee 230–260 gsm 26s–32s, or 40s double Body without losing the print surface
Sweatshirt face 280–320 gsm 26s–32s Soft with enough structure to hold shape
Hoodie fleece 350–450 gsm Coarse back, finer face Loft and warmth inside, clean surface outside

In our own POD line, both the 250 gsm tee (T244) and the 450 gsm zip hoodie (L246) are built on 40s double yarn. That choice was made for print surface and wash durability, not to hit a weight target.

Reading a Spec Sheet

Count is the number most often quoted and the least meaningful on its own. Six fields together tell you what the fabric will actually do:

  • Count and construction — 40s single or 40s double, stated separately.
  • Fabric weight in gsm — the number that governs warmth and drape more than count does.
  • Fibre composition as percentages, including any elastane.
  • Staple length — long-staple cotton spins stronger at the same count.
  • Shrinkage after wash — ask for the tested figure, not the promise.
  • Stitch density for knits — a tighter gauge holds shape but prints less crisply on textured surfaces.
Ask for a swatch at the gsm you are buying. A 40s swatch at 180 gsm and a 40s swatch at 250 gsm feel like different fabrics, because they are. Count is a property of the yarn; the garment is decided by everything else.

Yarn Count FAQ

  • Is a higher yarn count better? Not automatically. A higher count means a finer yarn — smoother and lighter, but not warmer. For hoodies a coarser yarn is usually the better choice.
  • What does 40s double mean? Two 40s single yarns twisted together. It costs more than 40s single and gives a more even, stronger, less pill-prone surface.
  • Does yarn count affect print quality? Yes. Finer, more even yarn gives the ink a cleaner surface, which is why print-heavy styles are usually built on 32s–40s double.
  • Does count change the price? Yes. Finer yarn needs more spinning passes and more fibre, so cost per kilogram rises — and it is the yarn, not the sewing, that drives most of the fabric cost.
  • Can I judge the count by touch? Not reliably. Ask for the spec and a swatch at the weight you are buying, and compare two samples at the same gsm.
