Necklace Size Guide
The right necklace lengths vary from person to person. Standard women’s necklace lengths are 16 to 20 inches, but different chain lengths are appropriate for different styles and outfits.
A 16" necklace hits just above the collarbone and fits like a choker. This is the ideal length for petite frames and is one of the most common women’s necklace lengths.
An 18" necklace falls right about at the collarbone and is the most popular chain length among women.
A 20" necklace falls a few inches below the collarbone, perfect for women who want some breathing room with their chain. This length chain works best with a higher neckline.
A 24" chain falls below the neckline.
A 36" necklace hangs below the bust and is typically reserved for long, beaded necklaces such as pearl necklaces. They are often wrapped around twice to form double strand necklaces.
