A few inches change everything. Knowing where each length falls makes shopping for necklaces much easier.
What to remember
- Necklace lengths are usually sold in inches, and where they fall depends on your neck size and build.
- An 18-inch chain, which typically sits at the collarbone, is a popular all-purpose length.
- Measure a necklace you already like, or use a piece of string, before buying online.
- For layering, choose lengths about 2 inches apart so each chain sits on its own.
Necklace lengths are usually listed in inches, but those numbers are hard to picture. A quick guide to where each length tends to sit makes it much easier to choose.
Common lengths and where they sit
These are approximate and assume an average adult neck. Where a chain falls on you depends on your neck size and build.
| Length | Common name | Where it usually sits |
|---|---|---|
| 14 to 16 inches | Choker or collar | Around the base of the neck |
| 18 inches | Princess | At or just below the collarbone |
| 20 to 24 inches | Matinee | Below the collarbone, above the neckline of most tops |
| 28 to 36 inches | Opera | Around the bust or lower |
| Over 36 inches | Rope | Long enough to wrap twice or knot |
Match the length to your neckline
- Crew necks and high necklines: short chains or long pendants that sit clearly above or below the neckline.
- V-necks: a pendant that follows the V, often 18 to 20 inches.
- Scoop and off-the-shoulder necklines: chokers and 16- to 18-inch chains.
- Button-up shirts: short chains that sit inside the collar, or longer layered pieces.
Buying tip: Lay a necklace you already own flat and measure it from end to end, including the clasp. That gives you a reliable reference when you shop online.
Layering
Layered necklaces look neatest when each chain sits on its own. A simple formula is to choose lengths about 2 inches apart, such as 16, 18 and 20 inches, and to mix chain weights or pendant shapes for interest.
Chain thickness matters too
A fine chain suits a small pendant and delicate layering, while a heavier chain can stand alone. Check that a pendant’s bail, the loop it hangs from, is wide enough for the chain you want to use.
Before you buy: If you react to some necklaces with itching or a rash, the metal may be the cause. Our guide to gold karats explains what jewelry markings tell you about what a piece is made of.
Try before you commit
If you can, try a few lengths in a store or use a piece of string to mark where each length would fall. It’s the easiest way to avoid a necklace that hides under your neckline or sits awkwardly. For more on fit, see our guide to finding your ring size.
Common jewelry questions
What length is best for a pendant?
Many people choose 18 to 20 inches for a pendant, so it sits at or just below the collarbone. Larger pendants often look better on slightly longer chains.
Do men’s necklace lengths differ?
Often, yes. Men’s chains are commonly sold in longer lengths, such as 20 to 24 inches, because necks are typically wider.
Can a necklace be shortened or lengthened?
Many chains can be shortened by a jeweler, and an extender chain can add a couple of inches. Ask before buying if you’re unsure of the fit.
