Men's Chain Length Guide: How to Choose the Right Necklace Length for Him

Short answer. For most men, a 20 inch (50 cm) chain is the right length. It sits just below the collarbone and shows at an open collar. Choose 22 inches (55 cm) if he is broad or tall, or if the necklace has a pendant you want resting on the upper chest. Choose 24 inches (60 cm) if he will wear it under a shirt or wants the pendant at mid chest. If you can measure his neck, add about 4 inches to get a 20 inch style drape, and about 6 inches to sit lower.

Chain length is the detail that decides whether a necklace looks like it belongs to him or like it was borrowed. Here is how each length sits, how to pick one for his build, and how to find his length without asking.

Men's chain length chart

Length	Where it sits on an average neck	Best for
18 in (45 cm)	Base of the neck, close fitting	Slim builds, a chain worn with no pendant
20 in (50 cm)	Just below the collarbone	The everyday default, shows at an open collar
22 in (55 cm)	Upper chest	Broad or tall men, small and medium pendants
24 in (60 cm)	Mid chest	Wearing under a shirt, a pendant that hangs freely
30 in (75 cm)	Lower chest, near the breastbone	Large statement pendants, layering

These positions assume an average neck. Most adult men measure somewhere between 14 and 17 inches around the base of the neck, with the middle around 15 to 16 inches. On a thicker neck every chain sits higher, so a 20 inch chain can sit where an 18 inch chain sits on a slimmer man.

Why 20 inches is the safe default

Jewelers recommend 20 inches more than any other men's length because it works with the most shirts. It clears the base of the neck so it never feels like a choker, and it is short enough to show at an open collar instead of disappearing into the shirt. If you know nothing else about him, 20 inches is the length least likely to be wrong.

It is also the length that suits a man who has never worn a chain before. It is present without being loud.

How to choose for his build

Neck and shoulders

The neck matters more than height. A man with a thick neck or broad, muscular shoulders should usually go one size up from the default, to 22 inches. On him a 20 inch chain can sit tight at the base of the neck. A slim man with a narrow neck can wear 18 or 20 inches and have it lie neatly at the collarbone.

Height

Height changes proportion more than fit. On a tall man a short chain looks small, so 22 or 24 inches tends to look more natural. On a shorter man a long chain can look like it is swallowing his torso, and 20 inches usually reads better. As a rough guide, start at 20 to 22 inches for men under 5 ft 8 in, and at 22 to 24 inches for men over 6 ft.

How he dresses

Think about the collar he wears most. A man who lives in open necked shirts and knitwear will see a 20 or 22 inch chain every day. A man in a shirt and tie five days a week will want 24 inches, so the chain and pendant sit below the top button and stay private. Many men wear a chain only under the shirt, where it is felt rather than seen, and for them a longer length is the comfortable choice.

Pendants change the math

A pendant adds its own drop below the chain. With the bail and the pendant itself, the lowest point can sit an inch or more below where the bare chain would. So a pendant necklace almost always wants a little more length than a plain chain, not less.

Small pendant, worn at the collar. 20 inches. The pendant sits just under the collarbone and shows in an open neck.
Pendant on the upper chest. 22 inches. The most balanced look for most men, and it gives the pendant room to lie flat instead of tilting at the collarbone.
Pendant worn under the shirt. 24 inches. Low enough to stay hidden under a buttoned collar and to rest flat against the chest.

All three Bucarti necklaces are pendant pieces on a solid sterling chain. The Twisted Necklace carries a twisted cross, the Braided Necklace a braided cross, and the Genesis Necklace a rectangular pendant. Each comes in 50 cm (20 in), 55 cm (22 in) and 60 cm (24 in). If you are unsure, 55 cm is the length that suits the most men with a pendant.

How to find his length without asking

Measure a chain he already wears

This is the most reliable method. Lay one of his chains flat, straighten it without stretching, and measure from the end of the clasp to the end of the other side. If he likes how it sits, buy the same length. If he complains it is tight or always hidden, go one size up or down.

Use his shirt collar size

A dress shirt label tells you his neck size, usually 15 to 17 inches. Add about 4 inches for a chain that sits around the collarbone, and about 6 inches for one that sits on the upper chest. A 16 inch collar points to a 20 inch chain for a close look, or 22 inches with a pendant.

Ask the person who knows

A brother, a close friend or his mother may know what he already wears. If not, look at photos of him. Where his current chain sits in an open collar tells you almost everything.

Layering two chains

If he already wears a chain and you are adding a second, leave a gap of 2 to 4 inches between the lengths so they lie apart instead of tangling. A common pairing is 20 inches with 24 inches, with the pendant on the longer chain. Mixing a plain chain with a pendant piece keeps the two layers distinct.

Common mistakes

Forgetting the pendant drop. A pendant always sits lower than the bare chain.
Going too short on a broad man. A chain that sits tight at the base of the neck is uncomfortable and looks undersized. When in doubt between two lengths, go longer.
Choosing a chain that is too light. A thin, light chain twists and curls instead of hanging straight. Solid silver has the weight to sit flat. Our guide on solid vs hollow silver explains how to tell the difference.

If the length is wrong

FAQ

What is the most popular chain length for men?

20 inches. It sits just below the collarbone on an average neck and works with open collars, knitwear and most shirts.

Is 22 or 24 inches better for a man?

22 inches if he wants the chain or pendant visible on the upper chest. 24 inches if he will wear it under a buttoned shirt or wants the pendant at mid chest. Broad or tall men often prefer one of the two over 20 inches.

What length chain should I get for a pendant?

Usually 22 inches. The pendant adds drop below the chain, and 22 inches lets it rest flat on the upper chest. Go to 24 inches if he will wear it hidden.

How do I measure a necklace he already owns?

Lay it flat and straight without stretching it, and measure from the tip of the clasp to the far end. That full length is the chain size.

Is 18 inches too short for a man?

Not for a slim neck and a plain chain, where it sits neatly at the base of the neck. For an average or broad build, or with a pendant, 18 inches usually feels tight and looks short.
