Unless you work with jewellery or are an avid jewellery buyer, you may not know what curb height means, nor what Ga stands for. These two terms are used when it comes to measuring different types of jewellery, and we use them here at jewellerybox so you can get a better idea of what your item will be like in real life.

| Curb Height | Gauge / Ga |

Curb Height

Curb height is a measurement used for chains which tells you the height of the links. This measurement can be used for both bracelets and necklaces. If you are after a thicker looking chain, then you will want to go for a larger curb height.

The ID bracelet below has a curb height of 3mm, and the chain has a curb height of 1.4mm. Curb height is generally measured in millimeters.


Most body jewellery is measured in gauge, Ga for short. This includes Nose Studs, Belly Bars and Labrets. A gauge number correlates to a measurement in mm, and the higher the gauge number the smaller the wire is.  When buying new body jewellery it is always worth finding out the gauge of the item you are currently wearing in the piercing so you can be sure it will fit comfortably.

The rest of jewellery tends to be pretty simple in its measurements and avoids fancy terms like Curb Height and Gauge. Hopefully this glossary will help you if you’re looking to buy a new piece of body jewellery or even a new chain.
