Choosing the right needle size to use with the yarn you select is important. A too-large needle produces a loose fabric, which will not wear well in socks. A too-small needle is difficult to work with, because the fabric is so dense.
The needle size you choose depends quite heavily on how you knit—if you tend to knit tightly, you might need a larger needle size than someone who knits loosely when using the same yarn.
As a general rule, most yarns labeled sock yarn suggest an appropriate needle size to use to produce a good fabric for socks.
However, when using thicker yarn such as DK or worsted weight, you should go 2-3 needle sizes down from the suggested needle in order to get a dense fabric.
