Measuring Body Jewelry (Gauge)

Gauge (G) refers to the thickness of the body jewelry. Length (L) refers to the length of the shaft of the design. For captive bead rings and circular barbells (also called horseshoes), length refers to the inside diameter.

At Pagoda, ear piercing is done using 20 gauge piercing earrings. These are among the smallest sizes, and are designed to create small holes sized for standard pierced earrings. This is the gauge commonly used for nose piercing as well.

Larger gauges, usually 14 – 18, are used for other areas like the belly button, lip, tongue and eyebrow. Stretchers can be used to enlarge a piercing in the ear or tongue gradually and with little discomfort, creating holes for even larger gauge designs.
