You found the perfect chain, so now comes the question we hear almost every day: what length should I order? It sounds small, but length decides whether a chain looks sharp or slightly off, and it's the one thing you can't easily judge from a photo.
Start with the standard lengths
Most chains come in 16, 18, 20, 22, 24 and 30 inches, and each one lands in a predictable spot. A 16-inch chain sits high on the neck, almost like a choker. 18 inches rests just at the collarbone. 20 inches falls a couple of inches below it, and 22 to 24 inches hangs toward the middle of the chest. Anything near 30 inches is a long statement piece that often gets doubled or worn over clothes.
Those numbers shift with your build. The same 20-inch chain looks longer on a slim neck and shorter on someone broader. A quick fix is to measure a necklace you already own and wear comfortably, then match that length.
A fine chain like this one sits right at the base of the neck, which is the look most people picture when they say 18-inch: 18K Gold Elegant Chain.
Match the length to the neckline
Think about what you wear most. With a crew neck tee, an 18 to 22-inch chain shows just below the collar, which is where you want it. A V-neck or open collared shirt gives you room for 20 to 24 inches, since the chain follows the line of the opening. Turtlenecks and high collars are the hard case, so go longer, 24 inches or more, so the chain sits on top of the fabric instead of disappearing under it.
For women's necklines, a scoop or boat neck pairs well with 16 to 18 inches, while a deeper V looks best with a 20 or 22-inch chain that echoes the shape. If you wear a pendant, aim for it to land a few inches above the neckline's lowest point so it doesn't get lost.
Thickness changes everything
Here's what catches people out. A thin 2mm chain and a chunky 9mm chain at the same listed length don't look the same on the body. Thick chains have more weight and a wider drape, so they sit lower and take up more visual space. If you're buying a thick Cuban, going one size shorter than you'd pick for a delicate chain usually looks better, and it keeps the links from bunching at the back of the neck.
Here are three lengths of the same style stacked together, so you can see how each inch changes where the chain lands: Rope Chain Necklace in 14K Yellow Gold.
Thin chains do the opposite. They can look lost at 24 inches, so most people keep fine chains between 16 and 20 inches, where the gold catches light near the face. If you like layering, space your chains about two inches apart so each one reads clearly, and put the thickest on the longest length.
Don't forget the clasp and the pendant
Chain length is measured end to end, clasp included, so a 20-inch chain lies a hair shorter once it's fastened. For pendants, the chain length also controls how the charm hangs. A larger pendant looks balanced on 22 to 24 inches, while a small initial or cross looks best on 18 or 20, close enough to be noticed.
A heavy 9mm Cuban reads shorter than its length suggests, because the weight pulls it flat against the chest: 14K Gold 9MM Miami Cuban Link Chain.
If you're gifting a chain and can't ask what they wear, 20 inches is the safest answer for most men and 18 inches for most women. It sits comfortably under almost every neckline, and the lobster clasp makes it easy to wear all day.
A quick way to decide
Cut a piece of string to the length you're considering, drape it around your neck, and look in a mirror with the kind of shirt you'd normally wear. It takes thirty seconds and saves a lot of guessing. If you land between two sizes, choose by thickness: shorter for chunky, longer for fine.
