Wire Lengths to Make 100 Jump Rings
Eliminate waste and reduce costs when making your own jump rings. This chart gives the specific length of wire needed to make 100 jump rings in particular diameters and gauge.
If you plan on making your own jump rings, all you need to know is the inside diameter (ID) and gauge you want to make. This chart gives the length of specific wire sizes needed to make 100 jump rings of a particular ID and gauge. Knowing how long your wire should be eliminates waste and reduces cost from having to order too much, as well as the frustration of not having enough material to work with. You'll also find the appropriate saw blade size for the most convenient cut after coiling.
Note: It is still recommended to order slightly more than necessary in case of variances in coiling tension, spring back and other variables.
