Sizing for A Nose Stud
End Styles
screw end for left or right nostril
L end (shaped like an L)
L up into the nostril (some designs)
L for left nostril (some designs)
L for right nostril (some designs)
bone end (straight shaft with little ball on the end - the ball does not unscrew)
straight shaft 17mm long (otherwise known as fishtail)
If you have a screw style stud that fits comfortably, order based on what matches your piece visually, even if it's opposite

My nostril or when you're looking at me? It's your nostril. Put your hand up to your piercing. Which hand is it? That's what side your piercing is on.
Shaft Length:
I make my shafts 6.5mm long
The small "L" part of my L ends are 5mm long, except on the L end for left or right, where it's a little shorter so it doesn't poke into your nostril.
The screw portion of my screw end nose studs is 4.5mm wide and the 'tail' of it points toward the septum.
Gauge
Gauge means how thick the wire is.
22G is thinner & daintier, 20G is a standard (fits most), and 18G is a little thicker
Nose piercings are more frequently done in 18G, and sometimes in 20G. 22G piercings are more rare and usually the result of "gauging down" in size because of preferring something thinner.
Your piercer could advise you on what you're currently wearing so you can stay consistent.
CUSTOM SIZING
I can make these to a size you require. You need to leave a note for the specific size if you need something other than my standard (eg. "please make my stud with a 7.5mm shaft length). Please don't leave "make them a bit longer, or "make them a bit shorter" in your order notes.
All of my nose studs are nickel free
European Sizing
In Europe, the thickness is indicated in millimeters, instead of in gauge.
The conversions are as follows:
24G = .511mm
22G = .644mm
20G = .812mm
18G = 1.02mm
16G = 1.2mm
