QUICK SIZING GUIDE
Quick Size Check

These are the measurements for this piece of jewellery. If this product has multiple sizes, the guide will use your selected size where available. Compare with jewellery that already fits you comfortably if you're unsure.

Gauge / Thickness 16G (1.2MM) The thickness of the jewellery that passes through your piercing.
Wearable Length 6MM - 8MM The wearable length of the bar or post, excluding decorative ends.
💡 Sizing Tip Gauge numbers work in reverse — the lower the gauge number, the thicker the jewellery.
Piercing sizes aren't one-size-fits-all. These recommendations describe common uses for healed piercings and are not a guarantee of fit. Always consider the jewellery design, your piercing placement and your individual anatomy. New or healing piercings should be sized by a professional piercer.
