Two numbers decide how a gold chain wears: how long it is, and how wide it is. Get them right and the chain looks like it was made for you. Get them wrong and a beautiful piece sits awkwardly for years.
Here's how to choose both.
Chain lengths, and where they actually sit
Chain length is measured end to end, clasp included. Where a given length lands on you depends on your neck size and build, but as a general guide on an average adult male frame:
- 16" — sits at the base of the neck, close and high. Uncommon for men's chains; more typical as a women's choker-adjacent length.
- 18" — sits at or just below the collarbone. A clean, close fit. Popular for thinner chains and for wearing under a collar.
- 20" — the most common men's length. Sits a couple of inches below the collarbone, at the top of the chest. Works with and without a pendant, tucked or visible.
- 22" — sits mid-chest. Very popular for Cuban links, where the extra length lets the chain display properly.
- 24" — sits lower on the chest, around sternum level. A statement length. Common for heavier Cubans and for layering under a shorter chain.
- 26"–30" — chest-length and below. Typically chosen for heavy pieces meant to be seen, or for larger frames where shorter lengths would sit too high.
If you're buying your first chain and you genuinely don't know: buy 22". It's the safest length across the widest range of builds and styles.
How to measure at home
Two methods, both take a minute.
The tape method. Take a soft measuring tape, wrap it around your neck where a chain would naturally sit, and note the measurement. That's your baseline "choker" length. Then:
- Add about 2" for a chain that sits at the collarbone
- Add about 4" for a chain sitting at the top of the chest
- Add about 6" or more for a mid-chest drop
The string method. No tape? Use a shoelace or a phone charging cable. Hold it against yourself and adjust until it hangs exactly where you want the chain to sit, mark the spot, then measure the string against a ruler.
The string method is better, because you're measuring the result you want rather than calculating toward it.
A note on neck size
Larger neck circumference eats length. If your neck measures well above average, a 20" chain will sit higher on you than it does on someone smaller — sometimes by a noticeable amount. If you're between two lengths and you have a broader build, size up.
The same works in reverse. On a slimmer frame, a 24" chain drops lower than the chart suggests.
Width: the mm number
Chain width is given in millimeters, measured across the widest point of the link. This is where the character of the chain lives.
- 2–4mm — subtle. Reads as jewelry rather than statement. Good under a shirt, good for layering, good as a pendant chain where you want the pendant to be the focus.
- 5–8mm — the everyday sweet spot for a Cuban link. Substantial and clearly visible, but still wearable with anything and comfortable for all-day wear.
- 9–12mm — statement territory. Unmistakable presence. Noticeably heavier on the neck, and the weight is part of the appeal.
- 13mm and up — heavy statement pieces. These are worn deliberately and they carry real gram weight.
There's no correct width. There's the width that matches how you want to be seen.
Width and length work together
The pairing matters more than either number alone. A wide chain at a short length looks compressed — the links crowd the neck and lose their line. A narrow chain at a very long length can look thin and lost.
Broad guidance:
- Narrow chains (2–4mm): 18"–22" generally
- Mid widths (5–8mm): 20"–24"
- Wide (9mm+): 22"–26", so the links have room to lay properly
Again — these are starting points, not rules. Plenty of people wear a heavy Cuban at 20" on purpose and it looks exactly right.
Width drives weight, and weight drives price
This is the part people don't expect: chain width affects price far more than length does.
Doubling a chain's width doesn't double its gold content — it roughly quadruples it, because you're increasing the link's cross-section in two dimensions, not one. So a 10mm Cuban isn't twice the price of a 5mm at the same length. It's considerably more.
Length scales the weight linearly. Width scales it geometrically. That's why an extra two inches costs a modest amount and an extra two millimeters costs a lot.
We publish the actual measured gram weight of every chain we sell for exactly this reason. If you want the full breakdown of how gold weight converts to price, we cover it in our pricing guide.

Frequently Asked Questions
What is the most common gold chain length for men?
20" and 22" are the most common. 20" sits at the top of the chest and 22" sits mid-chest on an average adult male frame.
How do I measure my neck for a chain?
Wrap a soft tape or string around your neck where a chain would sit, then add roughly 2" for a collarbone fit, 4" for top of chest, or 6" or more for a mid-chest drop.
Does a wider chain cost more than a longer one?
Yes, significantly. Width increases a chain's gold content geometrically because it increases the link cross-section in two dimensions, while length increases weight in a straight line.
What mm width is best for a Cuban link chain?
5mm to 8mm is the most versatile range for everyday wear. 9mm and above are statement widths with noticeably more weight.
