Will It Fit?
Will It Fit?
Yes! Our flatbacks use a universal fit crafted to work beautifully in nearly all standard ear piercings. Here’s how we guarantee a comfortable, secure fit:
✨ Most customers are happiest with 6mm.
💝 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.
✨ Recommended Sizes by Piercing
Most customers find these sizes work perfectly. These recommendations are based on standard piercing placements and common anatomy. Since everyone’s ears are unique, we recommend measuring your current jewelry or consulting your piercer for the most accurate fit.
