2-in-2 Chain Chainmaille Ring Sizes (Round Wire)

These are the round-wire jump ring sizes I use for 2-in-2 Chain, in 12g to 24g AWG. For each gauge you get the inner diameter (ID) in millimeters and rings per inch (RPI), so you can work out how many rings your piece needs. Every ring is saw cut by hand in our studio, as we've done since 2003. To try the weave before you commit, start with 2-in-2 Chain inchpacks or round wire jump rings.

As with all of our work, we invite you to make and sell as many of everything as you like, but ask that you don't publish our instructions or ring sizes.
