Jewelry Sizing

Disclaimer: We highly recommend visiting a  local studio to get measured for the proper size prior to purchasing.

There are two main systems of measuring body jewelry sizes:

  1. Gauge (“ga" or just “g") - We use "g"
  2. Millimeter (“mm")

In the United States, the gauge system is much more common than millimeter measurements. Here’s how it works with some example of sizing corresponding with the piercing. 

Nostril: 20g (0.8mm) or 18g (1.0mm) 

Ear Lobes: 20g (0.8mm) or 18g (1.0mm)

Tragus: 20g (0.8mm) or 18g (1.0mm)

Helix: 20g (0.8mm) or 18g (1.0mm)

Conch: 18g (1.0mm) or 16g (1.2mm)

Daith: 16g (1.2mm)

Septum: 16g (1.2mm)

Industrial: 14g (1.6mm)

Nipples: 14g (1.6mm)


Gauge (g) Millimeters(mm) Inches
20g 0.8mm
18g 1.0 mm 5/128"
16g 1.2mm 3/64"
14g 1.6 mm 1/16"
