How to Measure |
| 16G (Standard) |
1.2mm thickness |
Septum, daith, helix, lobe (standard & stretched) |
Use a calliper to measure the jewellery bar thickness. 16G is the most common body piercing size. |
| Inner Diameter Options: |
| 7mm |
Small inner diameter |
Standard septum piercings; typical anatomy without stretching |
Measure the distance across the inside of your current jewellery from edge to edge, passing through the centre. |
| 8mm |
Medium inner diameter |
Most septums, daiths, and stretched lobes are versatile across body types |
8mm suits average to slightly larger piercing anatomy. Best starting point if unsure. |
| 10mm |
Large inner diameter |
Stretched septums, daiths, and lobes; larger individual anatomy |
Choose 10mm if your piercing has been stretched or your natural anatomy requires more space. |
Finding Your Correct Inner Diameter
If you already wear a clicker or segment ring: Remove it and measure the inside distance straight across (the inner diameter). Match that measurement to your new clicker size.
If you're unsure: Consult your piercer. They can measure your specific piercing anatomy and recommend the ideal diameter for comfort and security.
Common Sizing Notes: Most standard septum piercings fit comfortably in 7mm or 8mm. Daith piercings typically need 8mm or 10mm due to the curved anatomy. Stretched lobes vary widely; if your lobe has been stretched to 10mm or larger, choose the 10mm clicker diameter.
