For everyday single jersey T-shirts, Ne 24/1 to 30/1 is most common at medium weights, and Ne 30/1 to 40/1 for fine, summer or premium tees. Ne 20/1 gives a thicker, more opaque fabric suited to heavyweight and oversized T-shirts.
Finer yarn means, at the same weight, a denser structure and a softer hand, but also a higher cost. The choice depends on the target weight and the machine gauge. Always ask for the yarn count together with the weight, because together they define the character of the fabric.
