At CALLSOUL, we prioritize your comfort and convenience. We are here to support you with both the perfect aesthetic choice but also the perfect fit. With our guide, we will carefully and clearly walk you on how to choose the proper size for your ear piercing. There are 4 main factors to remember: Gauge size refers to the thickness of the piercing. Barbell lengths refers to the wearable barbell length of studs. Diameter is used to measure hoops. Our chart is a standard guide. Your own personal sizes may differ, as everyone’s body is different. If you are unsure about your personal size, we would recommend contacting your original piercer to get the exact measurements.
