Existing necklace measurement
Got a necklace you already like? Measure it to find out which size to pick next. There are two simple ways to do this.
You'll Need:
- Tape measure or ruler
- A necklace you like
Option 1
Measure the full length

Lay the necklace down on a flat surface in a straight line. Measure it from one end of the clasp to the other and note down the length.
Option 2
Measure while it's hooked

With the necklace clasp closed, lay it down on a flat surface and measure its length from end to end. Next, double that measurement and note it down.
