A first silver chain is a classic gift for a son’s 16th or 18th birthday, a graduation, or a confirmation, and it is usually bought without asking his size. For most teenagers the answer is simple: a solid sterling chain 3 to 4 mm wide and 20″ long, in a curb, cable, or rope link, with a lobster clasp and no pendant he didn’t choose. This guide explains why, and what changes for a grown son.
Key takeaways
- 20″ for a teenager, 22″ for a grown son. A 20″ chain sits on a teenager’s upper chest and still sits below the collarbone once his neck has grown.
- 3 to 4 mm wide for a first chain; 4 to 5 mm for a grown son.
- Curb, cable, or rope, in solid sterling. Skip snake and herringbone, which kink for good, and hollow links, which dent.
- A lobster clasp, and the chain comes off for contact sports and the pool.
- No pendant unless he picks one, or the occasion calls for it, such as a cross for a confirmation.

Length: 20 inches for a teenager
Where a chain sits depends on his neck: subtract his neck size from the chain’s length, and about 4″ left over puts the chain just below the collarbone, 6″ on the upper chest. In a Canadian health survey of children and teenagers (Katz and colleagues, BMC Pediatrics, 2014), the typical 15-year-old boy’s neck measured 33.8 cm, about 13¼″, and the typical 17-year-old’s 35.5 cm, about 14″. A grown man’s neck is about 15½″ to 16″, as our chain length guide explains.
That growth is why 20″ is the length to buy a teenager. It sits on his upper chest now and settles just below the collarbone once he is grown, while an 18″ chain that looks right at 15 ends up snug at the base of his neck. For a grown son, 22″ is the safe default, as our guide to buying a chain as a gift explains. If he already wears a chain, measure it with the clasp closed and buy the same length.
Width: 3 to 4 mm for a first chain
Width decides how much the chain shows and how much it costs, because sterling is priced partly by weight. At 3 to 4 mm, a chain reads as his own rather than something borrowed from his father, and it is sturdy enough to wear every day: a solid 3 mm curb chain at 22″ weighs about 12 to 18 g, according to the ranges in our chain buying guide. For a grown son, 4 to 5 mm is the everyday width; go wider only if he already wears something heavier.
Style: links that can take a teenager
Teenagers sleep in their chains, wear them to practice, and stuff them in pockets, so the link style matters more than it would for a careful adult. Our comparison of chain styles rates the curb as very strong with a low risk of kinking, rope as strong when it is solid, and cable as medium strength with a low kink risk; Figaro, franco, and Byzantine chains hold up well too.
Snake and herringbone chains are the ones to skip for now: both are smooth, flat chains that kink permanently if they are bent sharply, which a teenager will do sooner or later. Whatever the style, buy it solid. Hollow chains, sometimes sold as “lightweight” or “semi-solid,” weigh 30% to 50% less, dent easily, and are hard to repair; our chain buying guide explains how to spot them by weight.
A clasp he can use, and when to take it off
A lobster clasp is the safe default: it is strong, a jeweler can replace it, and it is easy to work once he is used to it. Check that the end links are soldered closed and that the clasp or its tag carries a 925 stamp and a maker’s mark. Then tell him when the chain comes off:
- Contact sports and the gym. A chain can catch on a jersey or a hand, and a hard pull breaks the clasp or the chain.
- Pools, hot tubs, and the ocean. Chlorine and salt water are hard on silver; our guide to why silver tarnishes explains why.
- It can stay on in the shower and in bed. Plain water does no harm if the chain is dried afterward, and sleeping in a solid chain is fine.
A pendant, or not
Leave the pendant off unless he picks one. A symbol, a word, or a name says something about him, and at 15 or 18 that should be his choice; a plain chain can take a pendant later. The exception is an occasion that comes with one, such as a cross or a saint’s medal for a confirmation. Then go 2″ longer, because a pendant hangs below the chain and needs the room: 22″ for a teenager, 22″ to 24″ for a grown son.
Sterling silver or stainless steel?
Sterling is the better keepsake: it is a precious metal, a jeweler can repair or shorten it, and it polishes back to new for decades. Stainless steel is the practical choice for a younger teenager who swims every day or loses things, because it costs less, scratches less, and doesn’t tarnish. Our comparison of silver, steel, and titanium covers the trade-offs. For a 16th or 18th birthday, a graduation, or a confirmation, sterling is the gift that lasts.

If the length turns out wrong, a jeweler can shorten a chain, but making one longer means adding links or an extender. Ronatelli’s return policy gives you 30 days from the day you receive the piece, as long as it is unworn, with its tags, and in its original packaging. For a birthday or a graduation, allow two weeks: it takes one to two business days to process an order and two to seven to deliver it, depending on the warehouse, and you won’t know which until it ships.
FAQ
What size chain should a teenage boy wear?
20″ for most teenagers. It sits on his upper chest now and just below the collarbone once he is grown. An 18″ chain fits a younger teenager close to the neck, but he will outgrow it.
How wide should a boy’s first chain be?
3 to 4 mm. That is wide enough to be sturdy and slim enough to look like his own. A grown son can wear 4 to 5 mm every day.
What is the best chain style for a teenager?
A solid curb chain: it is very strong, lies flat, and doesn’t kink. Cable and solid rope chains are good too. Skip snake and herringbone chains, which kink permanently if they are bent.
Is sterling silver a good choice for a teenager?
Yes, if the chain is solid and he takes it off for contact sports and the pool. For a younger teenager who swims every day or loses things, stainless steel costs less and doesn’t tarnish.
Should a first chain have a pendant?
Only if he picks it, or if the occasion calls for one, such as a cross for a confirmation. Add 2″ to the length when there is a pendant.
Is a chain safe for a young child?
This guide is for teenagers and grown sons. For babies and toddlers, skip necklaces: in 2018 the FDA warned that teething necklaces and bracelets had strangled and choked infants and young children.
Bottom line
For a son’s first chain, buy solid sterling, 3 to 4 mm wide and 20″ long, in a curb, cable, or rope link with a lobster clasp, and leave the pendant to him. A 20″ chain fits a teenager now and still fits when he is grown; for a grown son, go 22″ and 4 to 5 mm.
