How to measure
Measuring necklace length
Measure and cut a piece of string to match the length of the necklace you’re considering. Place the string
around your neck to see where it sits. Take into account the size and shape of the pendant. If wanting to wear
multiple necklaces repeat this process to determine how necklaces of varying lengths might look when worn
together.
Tip
Necklaces vary by chain length and chain gauge. The size of your neck and size of the pendant will impact where
the necklace sits and how your necklace sits on its own and with other styles. Ask for advice as to the correct
size for the intended wearer.
