Measuring Necklace Sizes
When choosing a necklace, it's important to know your neck size so that your necklace lays in the position you would like. Every neck is different, on an average woman a 16 inch necklace may sit perfectly at the collarbone, yet a larger neck this may become a collar styled necklace, or a smaller neck this may become a princess styled necklace.
Take a soft measuring tape and wrap it closely around your neck. Hold the tape closely against your neck, not tight nor loose. When you have noted down your neck size, if for example the measurement is 14 inches, add on two inches (one necklace size) to find the smallest necklace length you can wear comfortably. You can then gauge the other styles from your 'base' size. Read over the average necklace styles below.
