Size Guide

Understanding Body Jewelry Measurements

Body jewelry isn't one-size-fits-all. Each piercing has its own sizing needs, and pieces are designed with different measurements to match both anatomy and personal style. Knowing how these measurements work helps you choose jewelry that looks good, feels comfortable, and fits exactly as it should.

Gauge (Thickness)

Gauge describes how thick a piece of body jewelry is. The numbering is a bit backwards: higher numbers indicate a thinner piece, while lower numbers indicate a thicker one. Most body jewelry is available in sizes ranging from 18g to 00g.

Diameter (Circular Jewelry)

Diameter is used to size circular body jewelry, such as captive bead rings, horseshoes, and other curved styles. It measures the distance across the inside of the ring at its widest point. Choosing the correct internal diameter is key — it determines how much room the jewelry has to sit comfortably in your piercing without feeling too tight or too loose.

Length (Barbell Jewelry)

Length refers to the measurement of the bar in barbell-style jewelry, taken from the inside of one end ball to the inside of the other. Choosing the right length is important to ensure a comfortable fit — too short or too long can cause irritation or even cause the piercing to reject the jewelry.

Choosing the Right Size

When choosing body jewelry, it’s important to pay attention to the gauge, diameter, and length that will work best for your piercing and style. If you’re ever unsure about the right size, a professional piercer can help. They can evaluate your piercing and recommend jewelry that fits comfortably and suits your needs.

Additional Tips

  • Always opt for body jewelry made from high-quality, biocompatible materials to reduce the risk of irritation or allergic reactions.
  • Keep your jewelry clean and disinfected regularly to maintain hygiene and prevent infection.
  • Pay attention to your body—if your jewelry causes discomfort or pain, remove it promptly.
  • Check in with a professional piercer for routine evaluations and to address any concerns with your piercing.
