In this regard, is my nose piercing 18G or 20G?
The thickest Gauge is 18 Gauge. This would be your choice if you have recently had your nose pierced or wear that gauge normally. 20 Gauge is thinner than 18G and is the standard most popular size. If you are unsure this would be your best choice.
Keeping this in view, how big is a 20G?
|Base diameter||.692 in (17.576mm)|
|Rim diameter||.761 in|
|Rim thickness||.050 in|
|Case length||2.270 in|
How many MM is a nose ring?
Everyone has a unique nose and because of this, gauge sizes for nose piercings vary slightly. Professional piercers are the ones to determine this. The most common sizes are 20 and 18 gauge, or . 8 and 1 millimeters (18-gauge being vaguely thicker).
If your nose piercing is less than or at least 6 months old, it will begin to get smaller/close up within a day or two. Especially the inner side of your nose piercing hole turns smaller very quickly.
