Cuban Link Chain Size Guide: 8MM vs 12MM
Most people spend time choosing chain length and get the width wrong. This guide fixes that — so you buy the right size the first time.
Why width matters more than most people think
Length is the first thing people check. Width is usually an afterthought — a number they pick without fully understanding what it means in practice.
On a Cuban link chain, width isn't just how thick it looks from the front. It affects how much surface catches light when you move, how the chain sits against your neck, whether it clears a collar without showing, and how much physical presence it has when someone's standing close to you. Two chains at the same length can feel completely different to wear. Width is why.
The good news: once you understand what each width actually does, the right choice usually becomes obvious.
The 8MM chain
8MM is the standard. Both widths are built for the same life — shower, gym, work, sleep, all of it — but 8MM handles the widest range of contexts without asking you to think about it. It sits flat against the neck. It works under a shirt collar without creating a visible ridge. It goes from the gym to a dinner without ever drawing attention to the fact that you're wearing jewelry.
The men who wear 8MM every day tend to stop noticing it after a few weeks. That's the point. You put it on, forget it's there, and it shows up every time someone glances down at your neck.
“I forget it's even there until someone asks about it.”
8MM works best for men with a neck under 16 inches, men who wear dress shirts regularly, and anyone who wants the chain to be present without being the loudest thing in the room. It's also the right starting point if you've never worn a chain before and aren't sure yet how much presence you want.
| Context | 8MM verdict |
|---|---|
| Office / dress shirts | Sits under collars cleanly |
| All-day wear | You'll forget it's on |
| Stacking with a bracelet | Chain stays understated |
| First Cuban link purchase | Lower commitment, still real presence |
| Neck under 16" | Proportional to frame |
The 12MM chain
12MM is built for the same everyday life as 8MM — shower, gym, work, sleep. The chain never comes off. The difference is presence, not purpose. It sits heavier on the chest, the links are wider and catch more light, and it has a physical weight that you feel from the first time you put it on.
Men who buy 12MM tend to know they want 12MM before they order. It's a deliberate choice about how visible they want the chain to be — not a different standard of durability or daily wearability.
“I went with 8MM because I wanted to wear it to work. Four years later I'd buy 12MM.”
12MM works for men of any build — but it earns its weight on broader frames where an 8MM can disappear against a wider neck. It's also the right choice if you wear t-shirts and open collars more than dress shirts, because the chain has room to be seen.
| Context | 12MM verdict |
|---|---|
| T-shirts and open collars | Full presence, room to be seen |
| Broader builds (neck 16"+) | Proportional, doesn't disappear |
| Wearing solo, no bracelet | Carries the look on its own |
| Office / dress shirts | Creates visible ridge under collar |
| Unsure between the two | 8MM is the safer starting point |
Chain length: the other number
Width and length work together. Most men wear Cuban links between 20 and 24 inches. Here's how to think about each:
| Length | Where it sits | Best for |
|---|---|---|
| 20" | Just below the collarbone | Slimmer builds, high-and-tight look |
| 22" | Top of the chest | Most men. The default. Works with most builds. |
| 24" | Lower chest | Taller or broader builds, relaxed fit |
If you're between lengths, go longer. A chain that sits slightly lower than expected is easier to live with than one that feels tight against your neck.
Buying for someone else? 22" is the safest default for most men. It works across the widest range of builds and styles. If he's notably slim, go 20". If he's 6'2"+ or wears XL and above, go 24".
Bracelet sizing: 7.5", 8", and 8.5"
BALANZI bracelets come in the same widths as the chains — 8MM and 12MM — and three wrist sizes. Wrap a flexible tape measure around your wrist just above the wrist bone. That's your wrist size.
| Wrist measurement | Bracelet size | Fit |
|---|---|---|
| Under 7" | 7.5" | Snug, close to wrist |
| 7" – 7.5" | 8" | Standard, slight movement |
| Over 7.5" | 8.5" | Relaxed, comfortable |
Most men wear 8". If you're between sizes, go with 8" — the slight room is more comfortable for all-day wear. Match your width: if your chain is 8MM, your bracelet should be 8MM. Same for 12MM. Mismatched widths look off.
The honest answer on which to choose
Unsure? 8MM. Already know you want presence? 12MM. The men who buy 12MM rarely wish they'd gone smaller.
Get either one wrong and the guarantee handles it. Keep the chain, get your money back — no questions.
