This is a rough Guide for the Sizing of body Jewellery for your piercings.
What are the common jewellery sizes for body piercings? As a general rule, one to two millimetres off the size of your initial jewellery will give you a good estimation.
Eyebrow piercing - usually 1.2mm or 1.6mm stem thickness by 6mm - 10mm in length
Ear lobes/rim piercings - if wearing 'normal' ear piercing jewellery usually 0.6mm - 1mm stem thickness, if wearing barbells or body rings without stretching usually 1.2mm - 1.6mm stem thickness, if you've stretched then you should know your size!
Ear lobe jewellery is usually 6mm - 8mm in length if it is a barbell or stud, ring sizes however vary greatly depending on the size of the lobe.
Tragus piercing - usually 1.2mm stem thickness (but occasionally 1.6mm thick) by 6mm - 8mm in length.
