Piercing Size Chart & Sizing Guide
The correct piercing size is important so that your jewelry fits comfortably, looks good, and suits the respective piercing site. In this size guide, we will explain the most important terms such as bar thickness, inner diameter, length, and ball size in a simple and understandable way.
What do the size specifications for piercings mean?
Bar thickness describes the thickness of the piercing bar. It is usually given in millimeters, for example, 1.2 mm or 1.6 mm.
Example
1.2 x 8 mm means: 1.2 mm bar thickness and 8 mm length or diameter.
The inner diameter is the distance inside a ring. It determines how tight or loose a ring fits.
Typical Values
6 mm sits rather tight, 8 mm is often standard, 10 mm looks a bit looser.
Length describes the usable bar length for straight piercing jewelry, for example, for barbells or navel piercings.
Important
Bars that are too short can press. Bars that are too long can slip or get caught.
Ball size describes the diameter of the ball or attachment. Small balls appear more subtle, larger balls more conspicuous.
Typical Sizes
3 mm appears delicate, 4 mm is often standard, 5 mm or more appears more conspicuous.

How to Read Piercing Sizes Correctly
Example: 1.2 x 8 mm
The first number almost always describes the bar thickness. The second number describes the length or inner diameter, depending on the type of jewelry.
For a Ring
1.2 x 8 mm means: 1.2 mm bar thickness and 8 mm inner diameter.
For a Labret or Barbell
1.2 x 8 mm means: 1.2 mm bar thickness and 8 mm bar length.
How do I measure my piercing correctly?
Measure a Ring
Always measure the inner distance from one inner side to the other. Do not measure externally, otherwise the size will be too large.
Measure a Bar
Only measure the usable length of the bar between the balls or attachments. The balls themselves are not measured.
Measure Bar Thickness
The bar thickness is best measured with a caliper. A regular ruler is often too imprecise for this.
