This is one of the most common questions we get for our chains. You should be seeing a few recommended sizes on this page but if you don't see them listed, fear not!

First, consider the width, length, and thickness on the links of the chain itself. Then consider the additional measurements we have for Smallest Possible Jump Ring Width and Thickest Possible Jump Ring. For most designs, the jump ring should be close in proportion to the chain links.

• Smallest Possible Jump Ring Width: This denotes the smallest outer diameter jump ring that can comfortably connect the two ends together. Keep in mind that the smallest width is often not ideal and that thicker jump rings may also affect how the chain lays. Using a jump ring that is slightly wider will allow for smoother movement of the chain when worn.
• Thickest Possible Jump Ring: This indicates the maximum diameter wire that will fit through the links of your chain. The thickest wire is often not ideal, but we list it so you have an idea of the limit of what is possible. 

Next, decide if you are closing the jump ring by welding or soldering it shut.

• If you are not closing the jump ring, then you should go with a heavier gauge than you would otherwise. 

Lastly, decide on the jump ring material.

• A rule of thumb is that it is usually best to not mix and match metal type or color. The main exception is that some people prefer welding solid gold jump rings onto gold filled chain because the solid gold tolerates heat much better.
