Yarn count and what it tells you about the fabric

Short answer: A high yarn count means a thinner, finer yarn. That gives a softer and more even fabric, but also a more delicate one.

How to read the number

Yarn count states how many metres of yarn go into one gram. A high number means thin yarn, meaning fine fabric. A low number means coarse yarn and robust fabric. It is the opposite logic to most numbers.

What it means for the feel

Fine yarn gives a smooth surface with no visible threads and feels softer against the skin. That is one reason two t-shirts of the same weight can feel completely different. See bamboo t-shirts for women.

Durability

Coarse yarn takes more abrasion, while fine yarn is more exposed to pulled threads and holes. For everyday clothing a middle level is often the best compromise. See bamboo clothing for women.

Where it shows most

In thin underwear and light t-shirts yarn count matters most. In sweat fabric and terry it matters less. See bamboo underwear for women.

Frequently asked questions

Is yarn count always in the description

Rarely in ordinary clothing. It is used mostly for bedding and shirting.

Is fine yarn always better

No. It is softer but more delicate. Choose according to what the garment is for.

Are yarn count and weight related

Partly. A fine yarn can be knitted densely and still produce a heavy fabric.
