Necklace Length Guide: What Chain Length Should You Buy?

For most women, an 18 inch necklace is the best first choice. It rests at the collarbone and works with almost every outfit. For most men, 20 to 24 inches is the most common range. Everyone is built a little differently, so use this guide to find the length that fits your neck, your clothes, and your style.

Picking a chain length sounds easy until you are staring at a list of numbers online. A 16 inch chain and an 18 inch chain only differ by two inches, but they can look very different when you wear them. This guide breaks it all down in plain words. You will see a simple chart, learn how to measure at home, and get tips for pendants, layering, and gifts.

Quick Necklace Length Chart

Here is the fast answer. Find your length, then read on for the details.

These numbers are a starting point. Your height, neck length, and body shape change where a chain lands. A 20 inch chain on a tall person will sit a little differently than on a shorter person. That is normal.

The Most Popular Length: 18 Inches

If you only remember one number, make it 18. An 18 inch necklace is the most common length sold in jewelry stores for a good reason. It sits at the collarbone, so it looks neat with crew necks, button-up shirts, and dresses. It also works as a base for layering later on.

An 18 inch chain is also the safest pick when you are buying a gift. It fits a wide range of people and styles. If you are not sure about the size of the person you are shopping for, 18 inches is a smart place to start.

What Each Necklace Length Looks Like

Let’s walk through each length so you can picture it.

14 to 16 inches: Chokers and Short Chains

A choker wraps close around the base of your neck. It should feel snug but not tight. A good test is to slide one finger between the chain and your skin. If it fits, the length is right.

A 16 inch chain is a little looser. It rests just above the collarbone. Many people like this length for a small pendant, such as a tiny diamond, a heart, or an initial. It is also a nice choice for women with a smaller frame.

18 inches: The Classic

This is the collarbone length. It looks good alone, and it pairs well with earrings of any size. If you wear a pendant, the pendant will rest right at the top of your chest, where it is easy to see.

20 to 22 inches: A Little Lower

These chains hang just below the collarbone. They suit V-necks and scoop necks, because the chain follows the shape of the neckline. A 20 inch chain is also a great choice for a pendant that is a bit larger or heavier.

24 inches: The Layering Length

At 24 inches, a chain sits in the middle of your chest. It works well over a sweater or a blouse. It is also a good outer layer when you stack two or three chains together.

28 to 36 inches and Longer

Longer chains are fun and bold. You can wear them long, or double them up to make a shorter layered look. Very long chains may swing when you move, so they work best for casual or dressy outfits and less so for active days.

Choose a Necklace Length by Neckline

Your clothes matter just as much as your neck. Here is an easy way to match them.

• Crew neck or round neck: Try 18 to 20 inches. The chain sits above the edge of the shirt, or just at it.
• V-neck: Try 18 to 20 inches. The pendant can point to the V.
• Scoop neck: Try 16 to 18 inches, so the chain frames the curve.
• Strapless or off the shoulder: Try a choker or 16 inch chain. Skin is the canvas here.
• Button-up collar: Try 20 to 24 inches, so the chain hangs below the collar.
• Turtleneck or high neck: Try 28 inches or longer, so the necklace sits on top of the fabric.

If you are not sure, hold a chain up to your outfit in a mirror. You will see right away if it looks too tight, too long, or just right.

How Pendants Change Your Length

A pendant is the charm or stone that hangs from the chain. It adds length of its own, because it hangs below the chain. That means a pendant on an 18 inch chain will sit a little lower than a plain 18 inch chain.

Think about the size of the pendant too. A small pendant looks sweet on 16 to 18 inches. A bigger pendant, like a large cross or a bold medallion, often looks better on 20 to 24 inches, so it has room to hang. You can browse our ladies pendants to see how different sizes look.

Chain Thickness Matters Too

Thin chains and thick chains hang in different ways. A thin chain feels light and sits a bit higher. A thick chain has more weight, so it tends to hang a little lower and feels bolder.

Because of this, you may want to go one size shorter with a thick chain if you want it to sit where the chart says. Or you can go one size longer with a very fine chain if you want it to drop a bit more. If you want to see styles side by side, take a look at our gold necklaces and chains post.

How to Measure Your Neck at Home

You do not need fancy tools. A piece of string and a ruler will do the job.

1. Cut a piece of string about 30 inches long.
2. Wrap it around your neck where you want the necklace to sit.
3. Pinch the spot where the string meets, and take it off.
4. Lay the string flat and measure it with a ruler or tape measure.
5. Add 2 to 4 inches. A necklace should drape, not cling.

For example, if the string measures 14 inches, the total is 16 to 18 inches. That is a good start for a chain that sits near the collarbone.

If you want a choker, add less. About half an inch to one inch is enough, so it stays snug but comfortable.

Measure a Necklace You Already Own

Here is an even easier trick. If you already have a necklace that you love, lay it flat. Measure it from one end of the chain to the other, and include the clasp. That number is your favorite length. Use it as a guide when you shop for something new.

Necklace Length for Men

Men’s chains follow similar rules, but the common sizes are a bit longer because of wider necks and shoulders.

• 18 inches: Sits close to the collar. Good for a clean, simple look.
• 20 inches: The most common everyday length.
• 22 to 24 inches: Great for pendants and thicker chains.
• 26 to 30 inches: Looks bold, and often sits on top of a T-shirt.

Thick chains can look heavy on a short neck, so try a few widths and lengths before you decide. Read more in our post on why a gold chain for men is a smart jewelry choice.

How to Layer Necklaces the Easy Way

Layering means wearing two or more necklaces together. It looks stylish, and it is simple once you know the trick.

• Start with the shortest chain. A 16 or 18 inch necklace is a nice base.
• Add a longer chain next. Go up by 2 to 4 inches each time. For example, try 16, 20, and 24 inches.
• Mix chain styles. A thin chain, a pendant, and a slightly thicker chain make a nice trio.
• Keep one focus. Let one necklace be the star, and keep the others simple.

Spacing the lengths apart stops your chains from tangling. It also lets each piece show. If the lengths are too close, they can bunch up and look messy.

Buying a Necklace as a Gift

Gift shopping can feel stressful. You want the necklace to look great, and you may not know the exact size. Here are some easy rules.

• Choose 18 inches if you are not sure. It is the safest bet.
• Pick a chain that has an adjustable clasp or extender, so it can be worn at more than one length.
• If you know she wears small pendants, go with 16 to 18 inches.
• If he usually wears collared shirts, go with 20 to 24 inches.
• Keep the receipt, and ask about exchange rules before you buy.

Buying a Necklace for a Teen

For a teen, 16 to 18 inches is a good range. Choose a chain with a small, light pendant. Adjustable chains are also helpful, because they work as your teen grows. If you are buying for a younger child, talk to a jeweler about safe lengths and clasps.

Common Necklace Length Mistakes

Even careful shoppers make these mistakes. Here is how to avoid them.

Forgetting the pendant drop. The pendant hangs below the chain, so the whole piece sits lower than you think.

Ignoring your neckline. A great chain can look off if it fights with your shirt. Match the length to the clothes you wear most.

Picking a choker that is too tight. You should always be able to fit a finger under it.

Buying a very long chain for daily wear. Long chains are fun, but they can snag on door handles and bags. For work or busy days, try 18 to 24 inches.

Skipping the clasp check. A strong clasp matters, especially on a necklace you plan to wear every day.

Do You Need an Extender?

A chain extender is a small piece of chain that adds a bit of length. Many necklaces come with one built in. It is handy if you want to change the length for different outfits. For example, you might wear a chain at 16 inches with a strapless dress, and at 18 inches with a sweater.

If a chain does not have an extender and you want one, ask your jeweler. It is a quick add-on in many cases.

Take Care of Your Chain

Once you find your perfect length, keep your necklace looking great. Take it off before you swim, shower, or sleep. Clean it gently, and store it so it does not tangle. We share easy steps in our posts on necklace cleaning tips and how to store jewelry at home.
