Flat Back Earring & Cartilage Hoop Sizing

Gauge Size

When it comes to flat back earrings and cartilage hoops, the first thing to know is gauge size, or the diameter of your piercing. The gauge size of your piercing refers to the thickness of the earring post that goes through your ear.

Everyone's ear is different, and your piercer may use a different sized needle depending on your exact ear size and shape, and your lifestyle, but here are some guidelines:

GAUGECOMMON PIERCINGS
20G (0.81mm)Most earlobe piercings are made with a 20G needle, as are some nose piercings.
18G (1.0mm)An 18G needle can be used for earlobe piercings, nose piercings, as well as some cartilage piercings  (e.g. forward helix). 18G earrings are great for many healed cartilage piercings.
16G (1.2mm)A 16G needle is used for most cartilage piercings, including the tragus, helix, rook, conch and daith.

Post Length / Ring Diameter

The length of your piercing refers to the wearable length of the earring post that goes through your piercing. For flat back studs, it’s the length of the post. For cartilage rings, this refers to the interior diameter of the ring.

Some standard sizes for various piercings:

What if I don't know what size Earring I need?

Your piercer will be able to tell you what size needle you were pierced with, along with the appropriate length/diameter you need.  Our recommendation is to ask your professional piercer for this information if at all possible.  

If you can't get in touch with your piercer, here's what we'd recommend trying as a backup:

Gauge Size: Insert a standard earring post through your piercing - this is going to be a 20G size post. If it fits snugly, then your gauge size will be 20G. If you can move it around a little bit, try an 18G size. If you can move it around quite a bit, then you probably want a 16G size.

Length/Diameter: Again try inserting a standard earring post into your piercing. Mark off on the post where you want the piece of jewelry to fit, and then upon removal, measure that length with a ruler. When in doubt, go a little larger in size so that you don't put undue pressure on your piercing.
