Summary

Grace Jones measures 9.32mm for gonion to mouth line, a jaw measurement that sits below its ideal range of 15.00 to 45.00mm and scores 8.0. The measurement assesses vertical jaw growth by comparing gonion position to the mouth corner, so a gonion below the mouth indicates sufficient growth for jaw volume. Her value is closest to those of Avril Lavigne and Wonyoung (IVE), both at 9.32mm, while Kate Li sits at the highest end with 32.94mm and Kathryn Watts at the lowest with -6.94mm. Her Ramus to Mandible Ratio and Gonial Angle are other parts of her full Harmony breakdown.
