SIZING PIERCING JEWELRY
When shopping for the perfect piece of body piercing jewelry you'll need to know what size you need. Here's some info to help you discover your perfect fit.What is "Gauge"?
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.Piercing Jewelry "Length":
The 'length' of your piercing jewelry refers to the "wearable" span of the barbell that goes through your piercing. It is measured from the top to the bottom of the straight or curved barbell and excludes the balls or charms.
Piercing Jewelry "Diameter":
The 'Diameter' is used to measure the size of round barbells such as hoops, captives, clickers, seam rings, and circulars. It is measured from the innermost and widest point of the circle, inside the hoop.
STANDARD PIERCING SIZES
Check out our chart below to discover the standard fit for different piercings. Just like clothing, piercing sizes vary from person to person, so the 'standard' size might not be right for you.
*Tip: Measure the size of your current piercing jewelry to ensure you're getting the correct size for your piercing.
