Piercing

After thickness, the length of straight posts—barbells, labrets, or press-fit posts—is measured as the length of the shaft between the two ends. This is the wearable surface of the post.

Circular jewelry is measured by the inside diameter of the ring (and not the outside diameter). This is true for fixed bead rings, captives, circular barbells, seamless rings, and septum clickers.  

Curved barbells are measured as the straight distance between the ends (not the length of the curve between the posts). This applies to jeweled navel curves as well.

Press-fit ends have a small “pin” that sticks out of the decorative end and fits inside the shaft of the hollow titanium press-fit posts. The two pieces stays together not by magic, but by tension; a slight bend is made to the pin which allows it to stay securely in place inside the hollow post.
