Men’s Chain Length Guide: How to Find the Right Fit

Length is the first decision when buying a men's chain. Before the link style, before the metal, before the width, the question that decides how the whole piece wears is how long the chain is and where it sits on the neck.

Men's chain lengths in the UK are sold in centimetres: 45, 50, 55, 60, and 65. Those are the same chains as 18, 20, 22, 24, and 65cm (65cm (26 inch)es) on the US conversion. Most men land on 50cm or 55cm. On a 5ft 11 build, a 50cm chain sits just below the collarbone and a 55cm drops onto the upper chest. This guide walks through the sit points for every length, how to pick between two, and how to measure at home when you're buying blind or gifting.

How Long Should a Men's Chain Be?

For most men, the answer is 20 or 55cm (55cm (22 inch)es). A 50cm (20 inch) chain sits just below the collarbone on an average 5ft 11 build and reads as the everyday default. A 55cm (22 inch) chain drops onto the upper chest, which reads slightly bolder and works well on taller builds or with an open collar.

Height is a starting point, not a rule. Roughly 5ft 5 to 5ft 11 tends to wear 50cm (50cm (20 inch)es) comfortably. 6ft and over tends to wear 55cm (55cm (22 inch)es). Broader necks and higher shirt collars sit the chain higher than the chart suggests, so if you're between two lengths for either reason, size up. A chain that sits a fraction low reads as intentional. A chain pulled tight against the throat reads as the wrong size.

The two lengths above cover most men. 45cm (45cm (18 inch)es) is a choker sit that reads high and works for a very narrow build or a specific styling choice. 24 and 65cm (65cm (26 inch)es) drop lower onto the chest and read as statement lengths, most often paired with a heavier width or a pendant.

The Chain Length Chart

Sit points below are for a solo chain on a 5ft 11 build with an average neck circumference (15.5 inch collar). A shorter build, a broader neck, or a stiff shirt collar will lift the chain higher. A taller build will drop it lower. Add a pendant and the lowest point of the piece moves down without changing where the chain itself sits.

Length	US	Where it sits, solo	Where a pendant lands
45cm (18 inch)	45cm	Choker sit. Close to the collar. Feels tight on broader necks.	Pendant lands at the collarbone. Choose when you want the piece high and visible in an open shirt.
50cm (20 inch)	50cm	Just below the collarbone. Everyday default. Most-bought length.	Pendant drops onto the upper chest. This is the chain length used in most of our pendant sets.
55cm (22 inch)	55cm	Onto the upper chest. The other length most men actually wear.	Pendant sits lower. Better if you're 6ft or want more drop with the pendant visible over the tee.
60cm (24 inch)	60cm	Lower chest. Reads long on a build under 6ft.	Pendant hangs low. Easy to overshoot on a shorter build.
65cm (26 inch)	65cm	Mid-chest. Statement drop.	Usually too long with a pendant unless the drop is the look you're after.

Not every chain in the range is cut in every length. Open the product page and pick from the lengths that style is available in. The full range is on the men's chains collection.

Solo Chain vs Chain With a Pendant

A pendant adds drop without changing the chain length. The clasp sits in the same place. The lowest point of the piece, which is now the pendant rather than the chain itself, sits lower than a bare chain of that length.

If the chain will be worn on its own, pick the sit you want from the chart and that's the length. If a pendant is going on it, decide where you want the pendant to land, not where the clasp sits. For most men the answer is a 50cm (20 inch) chain, which drops the pendant onto the upper chest, sitting cleanly under an open collar or over a plain tee. Our pendants ship with a matched chain already on them, so you're choosing the length of that chain, not buying a second one. Browse the range on the men's pendants collection.

Heavier pendants need a chain that can carry them without buckling. That's a pairing question rather than a length question, and it's mostly a case of matching the pendant's weight to the chain's width. The length still follows the chart above.

How Height and Collar Size Change the Fit

Two men of the same height can wear the same chain length and read completely differently, because the neck the chain sits on is doing half the work. Broader necks push the chain higher. Higher shirt collars do the same. Longer necks with a narrower base drop the chain lower.

A rough guide: a 15 to 15.5 inch shirt collar with a height under 6ft tends to sit best in a 50cm (20 inch) chain. A 16 inch collar, or a height of 6ft and over, tends to sit best in 55cm (55cm (22 inch)es). Above 6ft 2 and 17 inch collar, 60cm (60cm (24 inch)es) is worth considering, particularly for a bolder width where you want the chain to lead the outfit.

None of this is a rule. It's a starting point that catches the majority. If you have a chain at home that sits right, that's a more reliable data point than any height chart, and the measuring section below walks through how to use it.

If You're Between Two Lengths

Take the longer one. A chain sitting a fraction low reads as a choice. A chain sitting tight against the throat reads as the wrong size.

Use height and collar as the first cut. Then override with the sit you actually want. A 6ft man who wants the chain sitting at the collarbone still wants 50cm (50cm (20 inch)es). A 5ft 9 man who wants it dropping onto the chest still wants 22. The chart tells you where each length lands. The choice between two is a styling call, not a fit call.

The one situation where you size down is if the chain is going under a stiff collar or under a fitted turtleneck, where a longer chain will bunch and read badly. For hidden-under-shirt wear specifically, take the shorter option.

How to Measure Chain Length at Home

The most reliable way to buy the right length is to measure a chain that already sits where you want it to. When there isn't one, string works.

Method one: measure a chain you already own. Lay the chain flat on a hard surface, end to end, clasp included. Measure the full length from one end of the clasp to the other. That number is the length. Buy that length, or the next one up if you land between two shop sizes.

Method two: use a length of string.

1. Take a piece of string or ribbon long enough to loop around the neck.
2. Drape it around the neck and let it fall to the sit you want. Collar for a high sit, collarbone for the everyday default, upper chest for a lower drop.
3. Mark the point where the string ends meet at the back of the neck.
4. Lay the string flat and measure it in centimetres, or inches if that's easier.
5. Round up to the next available length if the measurement falls between two shop sizes.

Method three: buying as a gift when you can't measure the neck. Steal the data instead. A chain visible in a photo. Shirt collar size from a shirt in the closet. Height. A 15 to 15.5 inch collar with a height under 6ft is usually a 50cm (20 inch) chain. A 16 inch collar or a height of 6ft and over is usually 22. When you can't tell, buy 50cm (50cm (20 inch)es). It's the most-bought length across our range and the one that exchanges cleanest if the sit isn't right.

A ring sizer is not the tool for this. Ring sizers measure finger circumference at a much smaller scale and won't translate to a chain.

When You're Buying as a Gift

Chains are one of the easier pieces of men's jewellery to gift because the length range is narrow. 20 and 55cm (55cm (22 inch)es) cover the majority of adult men. If you have any information at all about height or collar, use it to pick between those two. If you don't, default to 50cm (50cm (20 inch)es).

Our gift sets pair a chain with a bracelet at a fixed length combination. The S/M set uses a 50cm (20 inch) chain, the L/XL set uses 55cm (55cm (22 inch)es). Same chains as the standalone 20 and 55cm (22 inch) options, packaged together. If you're gifting and want to make one decision instead of two, the sets are the shortcut.

If the length turns out to be wrong, we exchange. That's a safety net rather than a plan A, but it's worth knowing that a gifted chain isn't a locked-in decision.

Width vs Length: What Actually Changes

Length changes where the chain sits. Width changes how loudly the chain reads. They're independent decisions.

A 50cm (20 inch) chain in 2mm and a 50cm (20 inch) chain in 6mm both sit in the same place on the neck. The 2mm reads as a quiet line at the collarbone; the 6mm reads as a statement piece leading the outfit. If you're buying a first chain, 2mm to 4mm at 20 or 55cm (55cm (22 inch)es) is where most men land. If the chain is meant to be the piece the outfit is built around, step up in width rather than in length. Longer chains with heavier widths become jewellery-forward, which is a specific look rather than an everyday one.

Width is a style decision that belongs on the individual chain pages. Get length right first from the chart above, then read the link and width guidance on the piece you're leaning toward.

After Length: Picking the Link and the Metal

Length done. The next two decisions are the link style and the metal.

Link style is the shape of the chain: Cuban, Connell, rope, wheat, box, snake, figaro, tennis. Each has a different presence and a different set of styling rules. The pillar walks through all of them side by side on every men's chain style explained. If you want a broader read on how to choose between them, our piece on how to pick the perfect men's chain covers the buying-decision side.

The specific chain pages go deeper. For the everyday flat link, see what is a curb chain and what is a Connell chain. For a textured everyday, what is a rope chain and what is a wheat chain. For a clean geometric shape, what is a box chain or what is a snake chain. For a step up in presence, what is a figaro chain or what is a tennis chain.

Once you know the length and the link, the full range is on the men's chains collection. Open the product, pick 45, 50, 55, 60, or 65cm, done.

FAQs

How long should a men's chain be?
20 or 55cm (55cm (22 inch)es) for most men. A 50cm (20 inch) chain sits just below the collarbone on a 5ft 11 build. A 55cm (22 inch) chain drops onto the upper chest. Between the two, take 55cm (55cm (22 inch)es) unless you specifically want the chain sitting higher.

What is 50cm (50cm (20 inch)es) in centimetres?
50cm (50cm (20 inch)es) is 50cm. 45cm (45cm (18 inch)es) is 45cm, 55cm (55cm (22 inch)es) is 55cm, 60cm (60cm (24 inch)es) is 60cm, 65cm (65cm (26 inch)es) is 65cm.

What length should I buy if I'm shorter than 5ft 8?
Start at 50cm (50cm (20 inch)es). A 50cm (20 inch) chain sits at the collarbone on most builds under 5ft 11 and reads as the natural default. Only step up to 55cm (55cm (22 inch)es) if you specifically want the chain sitting on the upper chest.

What length should I buy if I'm 6ft or taller?
Start at 55cm (55cm (22 inch)es). A 55cm (22 inch) chain sits at the upper chest on a 6ft build and reads as the everyday default at that height. 60cm (60cm (24 inch)es) is worth considering only if you want a lower drop or you're pairing the chain with a pendant.

What length should I buy for a broader neck?
Size up. A broader neck lifts the chain higher than the chart suggests, so a 20 that sits at the collarbone on an average neck will sit tighter to the throat on a broader one. If the chart says 20, buy 22. If it says 22, consider 24.

What length should I buy for a pendant?
50cm (50cm (20 inch)es) is the default. That drops the pendant onto the upper chest, sitting visible over a tee or under an open collar. Step up to 55cm (55cm (22 inch)es) if you're 6ft and above or you specifically want the pendant lower.

Does a thicker chain need a different length?
No. Width changes how loudly the chain reads, not where the clasp sits. Length still follows the chart. Wider chains at longer lengths become statement pieces, which is a style choice rather than a fit adjustment.

Can I wear two chains at different lengths?
Yes, and it's the most common way to layer. A 20 and a 22 sit with a small gap between them and read as a considered pair rather than a tangle. Keep the widths similar so one doesn't dominate the other, or step them noticeably apart so the contrast is deliberate.

Do chains shrink or stretch over time?
Solid metal chains don't stretch under normal wear. Extremely thin chains can deform if snagged, but a chain in the 2mm-and-up range that we sell holds its length. If a chain feels shorter than it did, that's usually the wearer's build changing rather than the metal moving.

What if the length is wrong when the gift is opened?
We exchange. Length swaps within our returns window are the most common gift adjustment and the least complicated. Keep the receipt and the packaging clean.
