The most important thing when buying a piece of jewelry is that you choose the right size. Always use calipers when measuring your jewelry. You can also go to the piercing studio where you performed the piercing and ask them to measure the jewelry/piercing for you.

- The first thing to measure is the thickness of the jewelry.

- If you need to measure a ring, measure the inner diameter of the ring, that is the distance between the inner edges of the ring.

- When measuring barbells and labrets, measure the rod length between the balls.

- When measuring navel bananas and bananas measure the shortest distance between the balls.
