Necklace Length Guide: How to Choose the Right Chain Size

Shopping for a necklace is easier when you know how different chain lengths fit. A 16-inch necklace and a 22-inch necklace can look very different, even if they have the same design. This guide explains common necklace lengths, how to measure your preferred fit, and what to check before you buy.

Common necklace lengths and where they sit

These are general guides, not exact positions. Your neck size, height, build, and the chain's design all affect where a necklace falls.

• 14–16 inches: Usually sits close to the neck. A 16-inch chain may sit near the base of the neck on some people and higher on others.
• 18 inches: Often rests around the collarbone. This is a common everyday length for a simple chain or small pendant.
• 20 inches: Usually falls a little below the collarbone, offering more room than an 18-inch chain.
• 22 inches: Generally hangs farther down the upper chest. It can work well for a noticeable chain or pendant.
• 24 inches and longer: Typically creates a longer drop and may be worn alone or layered with shorter necklaces.

How to measure necklace length at home

The most reliable starting point is a necklace you already own and enjoy wearing.

1. Measure a favorite chain. Unclasp it, lay it straight on a flat surface, and measure its full length from end to end, including the clasp.
2. Try a string. Place a soft string around your neck so it hangs at the height you want. Mark where the ends meet, then lay the string flat and measure it. Keep the string loose enough to be comfortable.
3. Check the pendant. A pendant hangs below the chain, so consider its size and where its bottom will sit.
4. Look for an extender. Some necklaces have adjustable links or an extender chain. Others are fixed-length, so check the individual product details.

If you are buying a wider or heavier chain, remember that it may feel and drape differently from a thin chain of the same stated length.

18-inch vs. 20-inch necklace: what's the difference?

The difference is two inches of total chain length. On many people, an 18-inch necklace sits closer to the collarbone, while a 20-inch necklace hangs slightly lower. If an 18-inch chain feels too close to your neck, trying a 20-inch option may help. If you want a shorter, neater look, the 18-inch length may be a better match.

For a pendant necklace, the pendant's size matters too. A small charm and a large medal can look very different on the same chain.

20-inch vs. 22-inch necklace: which should you choose?

A 20-inch chain often works when you want a visible necklace without a long drop. A 22-inch chain gives you more length and may be easier to wear over some shirt necklines. Neither length is automatically better for men or women; choose based on the fit and style you prefer.

For examples from our current jewelry catalog, compare this 20-inch, 3 mm gold-plated Figaro chain with this 22-inch, 5 mm gold-plated Figaro chain. Notice that these two items differ in both length and width. The longer chain will hang differently, and the wider links will also create a bolder look.

Match the chain to how you plan to wear it

For everyday wear: Think about comfort first. If you wear the necklace all day, make sure it does not feel tight or catch on your clothing.

With a pendant: Picture the entire necklace, not just the chain. A pendant adds visual length below the point where the chain rests.

Over clothing: A longer chain may show better over a crew-neck top, while a shorter necklace may be easier to see with an open neckline. Try your usual outfits before deciding.

For layering: Start with two different lengths so the chains do not sit directly on top of each other. A gap of a few inches can help separate the pieces visually, although pendants and chain thickness also matter.

How to choose a necklace length as a gift

If you can, discreetly measure a necklace the person already wears. That is more useful than guessing from age, height, or gender. If you cannot measure one, check whether the style comes with an adjustable chain and review its length before purchasing.

Also check the material description. A necklace labeled gold-plated is not the same as a solid-gold necklace. Chain length, link width, metal, and finish are separate details worth comparing.

Quick answers to common questions

Is a 20-inch necklace too long?

Not necessarily. On some people it sits just below the collarbone; on others it hangs higher or lower. Measure against a chain you already like for the best comparison.

Does a 22-inch necklace fit everyone the same way?

No. Neck size, body proportions, chain style, and pendant weight all change the look.

Can I shorten a necklace after buying it?

Some chains can be adjusted or shortened, but not every design can. Check whether the necklace has an extender or ask a qualified jeweler before altering it.

Find a length that feels right

The best necklace length is the one that looks the way you want and feels comfortable to wear. Start by measuring a favorite chain, consider any pendant, and compare the stated length and width before choosing. You can explore more styles in our jewelry collection.
