How Long Should a Pendant Necklace Be?
Summary
Blue Nile calls 16 to 20 inches common lengths for women’s pendant necklaces and says men’s often have chains of 24 inches or longer, but no single length is right for everyone. Neck circumference, pendant size, neckline, and personal preference all change where the piece lands.
Chain length and pendant length are separate measurements. An 18-inch chain with a two-inch pendant finishes lower than an 18-inch chain with a tiny charm. Decide where you want the pendant to end, then test that spot before ordering.
To compare with a necklace that already lands where you like, lay it out straight and measure it from end to end with the clasp included, which is how Blue Nile measures its own.
The chain length does not tell you the full drop
Blue Nile describes two lengths to keep in mind: “The first is the length of the chain and the second is the length of the pendant itself.” When a product page says “18-inch pendant necklace,” the 18 inches is the chain. The pendant hangs below the chain’s lowest point, so a 38 mm (1.5 inch) cross on that chain ends about 1.5 inches lower than the chain alone.
This matters most with long bars, crosses, lockets, tassels, and larger pendants. Two necklaces can use the same chain length and still end at noticeably different points on the chest.
Use standard lengths as landmarks, not promises
Tiffany’s size guide lists 16, 18, 20, 24, 30, and 36 inches (40.5 to 91.5 cm). Blue Nile attaches landmarks to three of them: 16 inches sits “Just above collarbones,” 18 inches “Hangs over collarbones” and is “The most common length,” and 24 inches falls “Over blouse or dress.”
Those landmarks move with the wearer. Tiffany notes that “The circumference of your neck and size of the pendant will impact how your necklace sits.”
A larger pendant needs more room around it
A small solitaire, initial, or birthstone can sit neatly near the collarbone. A large medallion or long pendant may feel crowded in the same position, especially next to a high neckline or another necklace.
Tiffany’s guide suggests cutting string to the length you are considering, placing it around your neck, and considering “the size and shape of the pendant.” Mark where the bottom of the pendant would fall with a small piece of tape, then look at the whole silhouette in a mirror.
Your neckline can decide whether a length feels right
Open necklines leave a clear area for a pendant to sit on skin. Crew necks and sweaters can work well when the pendant sits clearly above the fabric edge or below it. The awkward spot is where the pendant keeps slipping in and out of the neckline.
Test the necklace with the clothes you expect to wear most often. A work necklace should be judged with your usual shirts and sweaters, not only with the neckline shown on a model.
Extenders and removable pendants
If the pendant is removable, whether it fits a given chain is a separate question, covered in our article on putting pendants on chains.
An extender helps when a pendant looks good at several heights. Check the base chain length and the extension separately: an 18-inch chain with a 2-inch extender covers 18 to 20 inches, two of Tiffany’s standard steps.
