You are staring at a size dropdown that says 5mm, 8mm, 12mm, 18mm, and you cannot picture the difference. A couple millimeters does not sound like much on paper. On your neck it is the whole look, the gap between a chain nobody notices and one that is the first thing people see. The Miami Cuban Link Chain comes in exactly those widths, so this guide maps straight onto what you are choosing between.
Here is what each thickness actually reads like, so you can pick once and get it right.
How thickness actually reads
Cuban link is measured by the width of the links across the chain. The bigger that number, the heavier the chain looks and the more it sits proud off your skin instead of lying flat. Thin reads clean and quiet. Thick reads bold and deliberate. Neither is more correct, they just say different things.
A quick way to think about the range Saphir carries, 5mm to 18mm:
5mm to 8mm: subtle and everyday
This is the range you wear and forget. A 5mm to 8mm Cuban sits close to the neck, slips under a collar, and reads as "he has good taste," not "look at my chain." It layers cleanly with other pieces and works at the office, at dinner, anywhere. If this is your first Cuban and you are not sure how much presence you want, start here. It is the hardest size to overdo.
9mm to 12mm: the balanced sweet spot
This is where most guys land. A 9mm to 12mm Cuban is clearly visible, has real weight to it, and makes a statement without shouting. It holds its own over a plain tee and still looks intentional over a button-down. A 10mm in particular is the classic middle: substantial enough to be the point of the outfit, restrained enough to wear daily. If you want people to notice the chain but not only the chain, this is the range.
It is also the range that photographs the best for most guys. Thick enough that the links read clearly on camera, not so heavy that it swallows the rest of what you are wearing. If you buy one Cuban and want it to do everything, this is the size that argues for itself.
13mm to 18mm: bold and full presence
This is a statement piece and it knows it. A 13mm to 18mm Cuban is heavy, sits high off the neck, and carries an outfit on its own. It photographs incredibly well, which is why you see this range on stage and in the feed. It wants some space to work, so it pairs best with a bigger frame and a wider neckline. On the right build it looks like money. Worn under a tight collar it can feel like too much, so match it to the room.
Match the thickness to your frame
The same chain reads differently on different builds. A broad chest and a thicker neck can carry a 12mm as an everyday chain, while the same 12mm on a leaner frame becomes a clear statement. If you are slim, sizing down one step keeps the proportions right. If you are bigger, sizing up keeps a chain from disappearing on you.
Thickness and length work together
A thicker chain looks best a little longer, because it needs room to lie in a clean curve instead of bunching up high on the neck. If you are going bold at 13mm or up, lean toward 20 to 22 inches so the links have space to sit right. A thin 5mm to 8mm chain can ride shorter, around 18 to 20 inches, and still look balanced. When in doubt, add length as you add width.
Necklace and bracelet do not have to match
A Cuban bracelet can run a touch chunkier than your chain and still look balanced, because your wrist is a smaller canvas and handles the weight well. A 10mm bracelet is a strong, versatile pick on its own or stacked with a watch. You do not need the exact same millimeter on both. Close in feel is enough.
The takeaway
Pick by the presence you want, then adjust for your frame. Subtle and daily is 5mm to 8mm. Balanced and versatile is 9mm to 12mm. Bold and unmistakable is 13mm to 18mm. When you are torn between two sizes, the thicker one always looks more expensive in photos and the thinner one is easier to wear every day.
