💝 How Piercing Jewelry is Measured
Measurements follow standard piercer sizing. Use the guide below and compare with jewelry you already own to find your best fit.
• Straight Barbell Length → Measure the wearable length between the end pieces
• Hoop Diameter → Measure straight across the inside of the hoop
• Curved Barbell Length → Measure end to end, following the curve
✨ Between sizes? Sizing up slightly usually offers the most comfortable fit.
