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!
