Chain length is measured end to end, including the clasp. Where a chain sits depends on your neck and build, so use the guide below as a starting point.
| Length | Inches | Where it usually sits |
|---|
| 40 cm | approx. 16" | Close to the base of the neck |
| 45 cm | approx. 18" | On or just below the collarbone |
| 50 cm | approx. 20" | A few centimetres below the collarbone |
| 55 cm | approx. 22" | Upper chest |
| 60 cm | approx. 24" | Mid chest, works over a crewneck |
How to measure
Easiest method: lay a necklace you already like flat and measure it end to end. No necklace to hand? Place a piece of string around your neck where you want the chain to sit, mark it, and measure the string flat. For layering, choose lengths around 5 cm apart.
