Two chains of the same stated length hang differently, and the reason is the link. Chain type changes how much a necklace stretches under weight, how high it sits, whether a pendant lies flat or flips over, and whether it survives being worn every day. This is the guide that gets skipped, and it causes more returns than length does.
The short version
Snake and box chains hang straightest and hold a pendant flat. Cable and rope twist more and sit slightly higher than their stated length. If a pendant keeps flipping over, the chain is the problem, not the pendant.

How each type behaves
| Chain | How it hangs | Best for | Watch out for |
| Snake | Perfectly straight, no twist | Pendants that must sit flat | Kinks permanently if bent sharply. Never store it folded |
| Box | Straight, slightly more flexible than snake | Everyday wear under clothing | Very little. The most forgiving type |
| Cable | Some twist, sits a little higher | Light pendants, layering | Thin cable stretches over years |
| Curb / Cuban | Lies flat, feels heavy | Worn alone, no pendant | Flat links catch on knitwear |
| Rope | Twists visibly, sits highest | Statement pieces | Hardest type to repair if a link goes |
| Figaro | Moderate twist | Men's chains, worn visible | The long links are the weak points |
The rule nobody tells you: chain type changes effective length
A rope chain of 20 inches sits noticeably higher than a snake chain of 20 inches, because the twist takes up length. The difference is small, roughly half an inch, but it is enough to move a pendant from just below the collarbone to on it.
So if you are replacing a chain and you loved where the old one sat, matching the number is not enough. Match the type too, or go one size longer when moving from a straight chain to a twisted one.
Which type for which pendant
If your pendant keeps turning backwards, the fix is almost always a snake or box chain. A round-link cable chain lets the pendant rotate freely; a flat-profile chain does not. Buying a heavier pendant will not fix it, and neither will a shorter chain.
Heavy pendants want a box or curb chain with enough gauge to carry the weight. A 0.8 mm cable under a heavy pendant will stretch and eventually break at the bail.
Small delicate pendants want a 1 mm snake or cable, so the chain does not visually outweigh the piece.
Pendants with a small hole need a thin snake or box chain, which passes through openings that cable and rope never will. If it still will not fit, there is a one-minute fix that does not involve buying anything.
Three chains that cover almost everything
A 1 mm sterling silver snake chain, around $29, is the one to own if you wear pendants. It passes through small holes, hangs dead straight and keeps the pendant facing forward.
A stainless steel box chain, around $13, is the everyday workhorse: stainless does not tarnish, does not react with sweat, and costs little enough to find out whether you actually wear it.
A 6 mm sterling Cuban link, around $37, is the option for a chain worn on its own with no pendant at all.
A note on plating
At any thickness under about 2 mm, avoid plated chains if you wear the piece often. The plating wears through at the back of the neck first, where the chain rubs against the collar, and it usually goes within a year. Sterling silver or stainless steel costs a little more and does not do this.
