General, a 16-inch (40cm) necklace can be wrapped around the neck like a chocker. For a petite woman, it will be slightly closer to the collarbone. Most necklaces have this size. It can be well matched with almost all clothing, filling the space on the collar.
The 18-inch (46cm) necklace is the most popular size among women, with its sag point just below the throat. This length of necklace is accompanied by a slightly larger pendant, which can make up for the space of the deep V neckline, making it a clear contrast with the clothing. Women with taller bodies, wearing a necklace of this size, might feel more like a choker.

18 inches (46cm): close to the base of the neck. Small size necklace for men.
20 inches (50cm): close to the collarbone, the most commonly used size.
24 inches (60cm): Sagging to the chest.
