How Do I Know What Size My Body Piercing Is?

Everyone's body is different, and sometimes piercers will use different lengths and gauges depending on your body or the type of body jewelry you want to wear. We've provided a list of industry standard sizes for body jewelry used for each piercing. However, we cannot guarantee that the size on our chart is the size used for your specific piercing. What you will find below are the standard gauges and lengths or diameters used by professional piercers. If you are unsure of what size piercing jewelry to get, we recommend calling or visiting your piercer to ask them.

Gauge

What Gauge Is My Piercing Jewelry?

The "gauge" of your piercing is the thickness of the bar that goes through your piercing. In other words, it's the barbell's thickness. Note that the thicker the barbell, the lower the gauge size. So a 12 gauge (or 12G) barbell is much thicker than a 20 gauge (20G) barbell.
