Gauge - G - refers to the thickness of the body jewelry, the lower the gauge, the thicker the body jewelry.
Length - L - refers to the inside length between the balls for barbells.
Diameter - D - refers to the inside diameter for rings.

Plugs, Tunnels, Earlets, Eyelets, etc. are measured by the outside diameter. This relates to the thickness of your piercing. The length of the tunnel is measured from rim to rim, which we call the wearable area.

 

Straight Barbells are very easy to measure. They are measured along the shaft between both balls.

Curved (Bent) Barbells are measured by the inner length between both balls.

All of our stock, externally threaded jewelry is made with 14g threading. This means that anything 14g will fit on 12g, 10g, or 8g shafts.
