A standard tennis ball measures 6.7 to 6.8 centimeters (2.64 to 2.68 inches) in diameter and weighs about 57-59 grams. For chains with holes, a general rule of thumb is to allow a small amount of extra length when cutting the chain to account for the holes. The specific requirement depends on how tight you want the chain to be around the object being held by the chain, or whether it is designed to open slightly when loaded in one direction but return quickly to its original form. Standard steel wire comes with a variety of hole diameters and can accommodate holes as small as 1 millimeter. Some chains have thicker links which make the smaller holes easier to thread over objects with smaller holes.
