How to measure cartilage studs

Cartilage studs length and gaugeCartilage piercings
The most popular sizes are 6mm for helix piercings and 8mm for tragus piercings but as everyone is different measuring the jewellery you have now is usually the best way to work out which size you need.

If you have any labrets or barbells you can measure the post or depending on the position of the piercing you might be able to measure your ear or how much of another stud goes through the piercing.  

Earlobe piercings
A simple way to work out the length is to put a standard earring against (not through) your earlobe and move the back to the right position, then take it away and measure the post to the butterfly back.

If you measure with calipers remember that you don't want the barbell to be too tight.


Most cartilage stud posts are 1.2mm (16 gauge) which is the same thickness as a standard piercing stud, we do also have some thinner 1mm (18 gauge) cartilage studs.
