Gauge Measure Converting and Measuring for Body Jewelry & Piercing Jewelry

Use the following table to determine the actual millimeter gauge size of all Gorilla Glass brand Body jewelry. Pay special attention to the 000 gauge and 7/16" gauge which appear to be the same millimeter size on our product pages, but are actually 10mm and 11mm:

Equivalent Gauge	Actual Gauge in Millimeters
18 gauge	1mm
16 gauge	1.3mm
14 gauge	1.6mm
12 gauge	2mm
10 gauge	2.5mm
8 gauge	3mm
6 gauge	4mm
4 gauge	5mm
2 gauge	6mm
0 gauge	8mm
00 gauge	9mm
000 gauge	10mm
7/16" gauge	11mm
1/2" gauge	12mm
9/16" gauge	14mm
5/8" gauge	16mm
3/4" gauge	19mm
7/8" gauge	22mm
1" gauge	25mm
1-1/8" gauge	29mm
1-1/4" gauge	32mm
1-3/8' gauge	35mm
1-1/2" gauge	38mm
1- 5/8" gauge	41mm
1-3/4" gauge	44mm
1- 7/8" gauge	48mm
2" gauge	51mm

Body jewelry and needles tend to be identified by their gauge, using the Browne & Sharpe or American wire gauge system, at least in North America (many other regions simply use metric sizing). The larger the gauge, the smaller the diameter
