Piercing Sizes

To check the size of the piercing there are 2systems to measure them Metric and Imperial. The metric system uses millimeters while the Imperial one uses gauges and inches. As default, we use both throughout the catalog for our clients’ convenience.

For those who are familiar with only one of these systems, please see the conversion chart below:

Piercing Sizes

Piercings are measured by thickness, diameter and width.

Ball Closure Rings are measured by the inside diameter.

Septum Clickers are measured by the pin thickness and the inside hight.

Straight and curved barbells are measured by the linear width from ball to ball.

1. Wiresize in Gauge or mm
It is the size of the stem (thickness of the wire) on most pieces of jewelry. Basically, it's the size of the hole people need to insert a piece of jewelry.

2. Size (length) in mm (length sizes we measure only in millimeter)

3. Ball or Attachment Size in mm (balls, spikes and all other attachments we measure only in millimeter)

Tip

Nose Piercings come in 0.8 or 1.0mm

Earstud pins are always 0.8mm

Eyebrow Piercings use always1.2mm

Labrets are most common in 1.2mm but also 1.6mm is available

Septum Piercings are most common in 1.2mm but also 1.6mm is available

1.6mm is the size for most piercing, like the industrial barbel, nipple, tongue or the navel.

Larger sizes are used for stretched holes.

Attachments

Ball or attachment sizes are a matter of taste but as a general guide, 3 and 4 mm balls are used for eyebrow or labret piercing and 5 and 6 mm balls for tongue piercing. Navel bananas usually have 8mm ball down and a 5mm ball on top.
In general the fashion trend goes to smaller attachments.
