The right necklace length varies from person to person, with standard women’s necklace lengths typically ranging from 16 to 20 inches. A 14-inch necklace usually fits like a choker, resting snugly around the neck for a close, fitted look. A 16-inch necklace, sits just above the collarbone and is an ideal choice for petite frames, making it one of the most popular lengths. The 18-inch necklace, falling right at the collarbone, is the most popular chain length among women, offering a versatile and flattering option for various styles and outfits.
