The nose piercing is one of the fastest and most adaptable piercings, and will adapt to whichever size gauge you put in it. If you have an 18G piercing you can wear 20G nose studs, nose screws or nose rings as well and your piercing will adapt very quickly. If you want to go back to an 18G, it will adapt.
Considering this, 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.
Likewise, is 18 or 20 gauge smaller? The higher the number, the smaller the gauge. If your piercing is a 18 gauge then the 20 gauge would be slightly smaller.
