There are multiple claims to the world's biggest ball of twine record, all within the United States. As of 2014, the ball of twine with the largest circumference is located in Cawker City, Kansas, measured at 8.06 feet (2.46 m) in diameter and 10.83 feet (3.30 m) in height.

Twine is a strong thread, light string or cord composed of string two or more thinner strands twisted, and then twisted together (plied). The strands are plied in the opposite direction to that of their twist, which adds torsional strength to the cord and keeps it from unravelling. This process is sometimes called reverse wrap. The same technique used for making twine is also used to make thread, which is thinner, yarn, and rope, which is stronger and thicker, generally with three or more strands.
