Necklace Sizing

To measure the best necklace size for you, take a tape measure and wrap around your neck to get its circumference.  Take that number and add 2" to 4" to determine the best minimum necklace length for you.  For a regular necklace, choose the second size up from your neck size as a minimum.  For example, if your neck measures 15" around, the minimum necklace size you should choose would be 17" to 19".  If you want a choker, stick with your exact neck measurement for the necklace size.  Standard necklaces sizes, common to most people, come in the following sizes:

• 14" to 16" is a standard choker length
• 16" to 19" falls just below the throat at the collarbone
• 20" falls slightly below the collarbone and is a good choice for low necklines
• 22" falls at or just above the neckline
• 24" falls below the neckline
• 36" can be worn as a long single opera length or doubled up
• Children's necklaces are usually between 14" to 16"
