Piercing Jewelry Size Guide

Measurements are product-specific. Use the gauge, wearable length, bar length, diameter or inner diameter shown on the individual listing. These terms describe different dimensions and should not be treated as interchangeable.

Know which measurement you need

Gauge describes the thickness of jewelry.
Wearable length or bar length describes the portion of a straight style that passes through the piercing.
Diameter or inner diameter describes the inside width of a circular style.

Always compare like with like. A diameter is not a substitute for a wearable length, and a photo is not a measurement reference.

How to check a fit

Use jewelry that already fits comfortably as your starting point.
Measure the dimension that matches the style you intend to wear.
Confirm whether the listing shows one piece or a pair, plus its closure and included components.
Check the intended placement and verify the material and care information before ordering.

When not to guess

Placement, anatomy, swelling, piercing age and preferred fit all affect what works. For a new, healing or irritated piercing, ask a qualified piercer rather than relying on general sizing guidance.

Continue your research

Choose a placement first if you are still deciding what you want to style.
Review materials and care before handling or storing jewelry.
