The 11 original Art of Chainmail Tutorials were created with Metal Designz standard stainless steel jump rings circa 2008 to 2010.
The following chart is for the standard inner diameter sizes from that time.
There are two Standard methods of measuring rings. Imperial Inches, or Metric Millimeters. AOC Tutorials have always used imperial. If you are used to using Metric measure and need some advice on which size rings to use, please contact your jump link supplier.
| Imperial (Inches) | Metric (Millimeteres) |
| 1/2" | 12.7mm |
| 7/16" | 11.1mm |
| 3/8" | 9.5mm |
| 5/16" | 7.9mm |
| 1/4" | 6.4mm |
| 3/16" | 4.8mm |
| 5/32" | 4.0mm |
| 9/64" | 3.6mm |
| 1/8" | 3.2mm |
| 3/32" | 2.4mm |
| 5/64" | 2.0mm |
| 1/16" | 1.6mm |
