 The size of a piercing depends on the type of piercing, the gauge, and the length of the post.

Gauge

• Gauge refers to the thickness of the post that goes through the piercing.
• Higher numbers are thinner, so a 16 gauge post is thicker than an 18 gauge post.
• The gauge size you choose depends on the size of your piercing hole.

Length

• The length of the post depends on the type of piercing and the thickness of your ear.
• Shorter posts are better for helix, tragus, and conch piercings, while longer posts are better for industrial piercings.

Standard sizes

• Nose: 20G (0.8mm) or 18G (1mm) gauge, 6mm or 8mm length
• Earlobe: 18G (1mm) or 20G (0.8mm) gauge, 6mm or 8mm length
• Nipple: 14G (1.6mm) gauge, 10mm, 12mm, or 14mm length
• Septum: 14G (1.6mm) or 16G (1.2mm) gauge, 10mm, 11mm, or 12mm length

You can measure your own fingers to find the right size.
