The length of yarn in a hank varies with the market and the material; for example, a hank of cotton yarn traditionally included 840 yards (768 meters) of yarn, while a hank of wool yarn was 560 yards (512 meters). For both cotton and wool, these traditional hanks are equal to 7 leas or to 12 cuts. In the U.S., however, a hank of woolen yarn is generally 1600 yards (1463 meters).
