Every neck is different and there is no one size fits all guide but we do have some tips and tricks to help you find your perfect fit.

 

Option #1 Measure a necklace you already love!

If you already have a necklace you love the length of, measure that chain against a ruler from end to end (don't forget to include the clasp) and make a note of the length.

 

Option #2 Measure with a string

Don't have a necklace that you love the length of? You can use a piece of string or a flexible measuring tape to find your desired length. Simply wrap it around your neck to get an idea of where you'd like your necklace to fall and take note of that measurement!

Option #1: Measure a ring you already have

The best way to decide on your ring size is to measure

the inner diameter of a ring that fits the desired finger.

Compare that measurement to the chart below to determine your size.


Option #2: Measure your finger

Wrap a string around your finger and then measure it in mm.

Compare that number to the chart below.
