How To MeasureYour Piercing

It is very important that the correct size of body jewllery is worn. If you select a size that is too small, irritation of the piercing could occur and if its too large it could catch on clothing resulting in a tear.

All body jewellery is measured in the following way:

How to measure body piercing jewellery

Length or Diameter (Shown as A and B in above diagram)

The above diagram shows you the measurements required for a Belly Bar, Barbell, Labret and Ball Closure Ring (BCR). Use this guide to measure your current jewellery that fits you well. It is also possible to measure between the holes on your piercing using a ruler or vernier guage although this method is difficult on your own and will not always prove to be totally accurate.

Thickness / Guage (Shown as C in above diagram)

There are common sizes for certain types of piercing:

  • Belly, Tongue and Nipple Jewellery is typically (1.6mm or 14 gauge)
  • Eyebrow is typically (1.2mm or 16 gauge)
  • Ear Piercings (Standard Lobe Piercing 1mm or 18 gauge) Tragus or Helix typically (1.2mm or 16 gauge)
  • Nose Piercings either (0.8mm or 20 gauge) or 1mm (18 gauge)
  • Labret Facial Piercings are typically (1.2mm (16 gauge) or (1.6mm 14 gauge)

Ball Size (Shown as D in above diagram)

In Europe jewellery thickness is shown in millimeters but in other parts of the world they use a gauge size. The table below should show you how to convert from each unit of measurement.

Thickness Conversion
* 1mm = 18 gauge
* 1.2mm = 16 gauge
* 1.6mm = 14 gauge
* 2mm = 12 gauge
* 2.4mm = 10 gauge
* 3.2mm = 8 gauge
* 4mm = 6 gauge
* 5mm = 4 gauge
* 6mm = 2 gauge
* 8mm = 0 gauge
Length/Diameter Conversion
* 6mm = 1/4"
* 8mm = 5/16"
* 10mm = 3/8"
* 11mm = 7/16"
* 12mm = 1/2"
* 14mm = 9/16"
* 16mm = 5/8"
* 18mm = 11/16"
* 19mm = 3/4"
* 21mm 13/16"
