How to Measure Your Conch Piercing

The conch piercing is located in the cup-like hollow of the ear cartilage and can be done in two ways. An inner conch piercing is placed in the middle of the ear's basin and typically uses a stud or flat-back labret. An outer conch is placed higher up on the flat cartilage ridge and is usually fitted with a large hoop that wraps around the outer ear.

Why measurement matters

This guide to conch piercings covers two key measurements for your conch jewelry: gauge and diameter. Getting either wrong can lead to jewelry that pulls, sits awkwardly, or causes irritation during healing. Every ear is shaped differently, so there is no standard size that works for everyone.

How to measure your conch piercing

Most conch piercings are done with a 16 gauge (1.2mm) needle, which promotes stability during healing. Once fully healed, some people downsize to an 18 gauge (1.0mm) for a more delicate look. Your piercer can advise on whether downsizing makes sense for your anatomy.

If you plan to wear a stud, you need to measure the thickness of your ear cartilage. Hold a ruler or small strip of paper against the back of your piercing hole and note how many millimeters it takes to reach the front of the tissue. Most people fall somewhere between 1/4" (6mm) for a snug fit and 5/16" (8mm) for thicker cartilage.

To find the right hoop size, cut a small strip of paper and use a mirror to align one edge exactly with your piercing hole, keeping the strip horizontal. Mark where the paper meets the outer rim of your ear cartilage, then measure the distance in millimeters.

Always round up when selecting conch jewelry, as pieces that are too small will press against the cartilage and cause irritation and inflammation. For an outer conch piercing, your piercer will be able to measure the placement accurately at the time of the piercing and recommend the right starting size.
