Body Jewellery Size Guide
Body jewellery is measured by both gauge (needle width/thickness) and post length, with different gauges and lengths being more suited to different types of piercings. The post length includes only the piercing post and not any balls or attachments.
Most piercings are performed using the standard sizes, however you can also request different gauges depending on the location and personal preference of the customer.
Below is a general guide of the standard sizing for various piercings, depending on an individuals anatomy there can be variations and it may be a case of trial and error to find your best fit. We recommend measuring a piece you're currently wearing to gain a rough idea prior to purchasing your new jewellery or ask your body piercer the size they used for the implant.
| Placement | Gauge | Post Length | |
|---|---|---|---|
 |
Navel |
14g (Standard) Can also shrink in width to a size 16g if piercing left to partially close and standard sizes don't fit. |
10mm (Standard) Can also vary from 6mm up to 19mm depending on piercing age and accuracy. Body weight is not usually a factor for piercing measurements. |
 |
Nipple | 14g (Standard) |
16mm (Standard) Can also vary from 6mm up to 19mm |

How to establish your preferred length for body jewellery.
The listed length (inches" or millimetres as shown above) refers to the distance between the balls. It is the length of the piercing shaft in fractional inches/millimeters and not the length of the full body jewellery.
If you are unsure what size you are, measure a piece of body jewellery that currently fits you correctly and this will assist you in establishing the best size moving forward. You may need to adjust your preferred sizing up or down depending on whether or not the current fit is as snug as you would like or perhaps too tight.
Length Conversion (eg. 3/8" 10mm)
| Millimeters | Fractional Inches |
| 6mm | 1/4" |
| 8mm (short length) | 5/16" |
| 10mm (standard sizes) | 3/8" |
| 11mm (standard sizes) | 7/16" |
| 12mm | 1/2" |
| 14mm | 9/16" |
| 16mm | 5/8" |
| 19mm | 3/4" |
| 22mm | 7/8" |
| 25mm | 1" |
Gauge - width of the shaft (eg. 14g)
Body jewellery is measured by gauges. The higher the gauge the skinnier the piercing post becomes. For example a 12g post is far thicker than a 19g post.
Refer to the chart below for specific details.
| Gauge | Millimeter | Inches |
| 20g (standard septum) | 0.81mm | 1/32" |
| 18g (standard septum) | 1mm | 3/64" |
| 16g (standard septum) | 1.2mm | 3/64" |
| 14g (standard navel) | 1.6mm | 1/16" |
| 12g | 2mm | 5/64" |
| 10g | 2.4mm | 3/32" |
