The label on your yarn will indicate  the ideal needle size to knit or crochet that yarn. The size on the label refers to the thickness of the needle, not its length.

In Europe, the needle size is given in millimeters. In the United States, the size is a number between 0 and 50. Then in the United Kingdom and Canada, size is a number between 18 and 000.
