Inverted Roundmaille Chainmaille Ring Sizes (Round Wire)

These are the round-wire jump ring sizes I use for Inverted Roundmaille, in 18g to 20g 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 Inverted Roundmaille inchpacks or round wire jump rings.

Weave	Shape	Gauge	ID (mm)	RPI
Inverted Roundmaille, Round 18g	RD	18	4.000	23.4
Inverted Roundmaille, Round 20g	RD	20	3.250	30

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.
