21 gauge SWG = 0.8
20 gauge AWG = 0.8

Why are the True Aspect Ratio (TAR) and the Anticipated Aspect Ratio (EAR) different? Because the EAR is calculated on the Mandrel Size and the advertised Gauge Size - these both vary in the real world. The TAR is based on the actual accurate measurements of the jump ring diameter and wire thickness.
