The size of body jewelry is calculated by measuring the diameter of the material that fits directly inside the piercing site. If your piercing is less than 9mm thick, there will be a corresponding gauge size. The gauge measurement system, which was originally formulated for wire, helps standardize body piercing sizes. By converting the gauge into millimeters or inches, it is easy to figure out approximate desired sizes with a simple tape measure.

You might also find larger piercings in the lip, nasal septum and tongue. Even though the final piercing result will stretch beyond a gauge measurement, it is important to be familiar with all gauge sizes because stretching doesn't happen overnight, and you're going to have to start somewhere. If you have a regular piercing that has fully healed, your next step would be to start with an earring that is either 16 or 14 gauge. One important thing to remember is that if you stretch your ears beyond 2g or 0g, there is a chance your ears will never fully close on their own. Do you know how large you want your piercing to be?
