A chain is the gift where size matters most and is hardest to ask about. Too short and it sits tight at his throat; too wide and it looks like someone else’s jewelry. The good news is that you don’t need to ask. Chains are sold in a few standard lengths, one of them suits almost every man, and there are three quiet ways to find his exact size. This guide covers length, width, style, and the clasp, plus what to do if it still sits wrong.
Key takeaways
- 22″ is the safe gift length. Choose 20″ for a slim man who likes a close fit, and 24″ for a big build or a chain that will carry a pendant.
- Or find his exact size: measure a chain he owns, check where his chain sits in a photo, or add 4″ to 6″ to his shirt collar size.
- 3 to 5 mm wide for a first chain. If he already wears one, match its width or go a millimeter wider.
- A classic style: curb, rope, Figaro, box, cable, or Byzantine, solid rather than hollow, with a lobster clasp.
- Keep the tags. If it sits too high or too low, exchange it for the next length rather than living with it.

Length: 22 inches is the safe gift
More men buy 20″ chains than any other length, with 22″ second, as our chain length guide explains. For a gift, 22″ is the better bet. A chain sits higher on a thicker neck, and you can’t see his: on a man with a 17″ or 18″ neck, a 20″ chain sits close to the base of the throat. A 22″ chain lands between the collarbone and the upper chest on almost every man, and a chain that sits a little low looks deliberate, while one that feels tight never gets worn.
| Length | Where it sits (15″–16″ neck) | Give it when |
|---|---|---|
| 20″ | Just below the collarbone | He is slim, or already wears his chains close |
| 22″ | A couple of inches lower, on the upper chest | You don’t know his size; the default for most men |
| 24″ | Mid-chest | He is tall or broad, or the chain will carry a pendant |
| 18″ | At the base of the neck | Rarely; only for a very slim man who wants a close chain |
Men’s chains come in two-inch steps, so you are choosing between neighbors. When in doubt, go longer.
Three ways to find his exact size
If you want more than the safe default, any one of these gets you to his length without asking.
- Measure a chain he already wears. Borrow it while he is out, lay it flat with the clasp closed, and measure it end to end. Buy the same length, or 2″ longer if you are adding a pendant.
- Look at a photo. Find one where he is wearing a chain. Just below the collarbone is about 20″; a couple of inches lower, on the upper chest, is about 22″.
- Use his shirt collar size. The number on a dress-shirt label is his neck size. Add 4″ for a chain just below the collarbone or 6″ for one on the upper chest, and round up to an even length: a 16″ collar gives 20″ or 22″.
Width: 3 to 5 mm for a first chain
Width is listed in millimeters, and it changes the look more than the length does. If he already wears a chain, match its width or go a millimeter wider; a big jump in width reads as a different kind of jewelry. If he doesn’t, these are the safe ranges:
- 2 to 3 mm: slim and quiet, easy to wear under a shirt. Good for a man who has never worn a chain.
- 4 to 5 mm: the everyday width. Visible over a T-shirt without being loud.
- 6 mm and up: a statement piece, and heavier and more expensive than it looks. Buy it only if he already wears chains this size.
Weight rises much faster than width: a solid 6 mm curb chain weighs three to four times as much as a 3 mm one. Our chain buying guide has a to-scale chart of widths and the typical weight of each.
Style: pick one that is hard to get wrong
The classic weaves suit almost any man and any outfit: curb (also sold as Cuban), rope, Figaro, box, cable, and Byzantine. Foxtail and wheat are a little more refined. If the chain will carry a pendant now or later, choose box, wheat, franco, or rope, which carry a pendant best; see our chain styles guide for how each one looks and wears. Some Ronatelli examples at their listed prices, all offered in 20″, 22″, 24″, and 26″:
- Fuli snake chain (2 mm), $149: the slim, smooth choice for a first chain
- Duomo cable chain (4 mm), $249, or Alfo bamboo chain (3 mm), $299
- Sergo foxtail chain (4 mm), $329, or Pudolf Byzantine chain (4 mm), $339
- Parma twisted chain (6 mm), $329, or Cana curb chain (7 mm), $499, for a man who already wears a heavier chain

Clasp and construction
- Solid, not hollow. Hollow links are lighter and cheaper but dent and kink. The listing should say solid and give a weight in grams.
- A lobster clasp is the easiest for a man to work with one hand; heavy Cuban chains use a box clasp with safety catches.
- Soldered end links, so the clasp can’t pull loose from the chain.
- A 925 stamp and a maker’s mark on the clasp or a small tag. Our guide to what 925 means explains the marks.
If it sits wrong, exchange it
Have him try it on with the tags still attached. If it sits high against his throat, or lower than he likes, exchange it for the next length rather than living with it; a chain in the wrong length is the one that ends up in a drawer. Ronatelli’s return policy gives you 30 days from the day you receive the piece; it has to be unworn, with its tags and in its original packaging, and a size change means sending it back and ordering the right one.
For Christmas 2026, order by Monday, December 14, for pieces that ship from US stock, and by Friday, December 4, for anything that ships from overseas. Ronatelli ships from a warehouse in the US or overseas and you won’t know which until it ships, so treat it as an overseas order. Our holiday gift guide has the full table of order dates.
FAQ
What length chain should I buy a man as a gift?
22″ is the safe choice when you don’t know his size: it sits between the collarbone and the upper chest on most men. Choose 20″ for a slim man and 24″ for a big build or a pendant.
Is 20 or 22 inches better for a man?
20″ sits just below the collarbone and is the most popular length for men who choose their own. 22″ sits a couple of inches lower and fits a wider range of neck sizes, so it is the safer gift.
What width chain should I get him?
3 to 5 mm for a first chain: 3 mm is slim and quiet, 5 mm is the everyday width. If he already wears a chain, match its width or go a millimeter wider.
How do I find out his chain size without asking?
Measure a chain he owns end to end with the clasp closed, check where his chain sits in a photo, or add 4″ to 6″ to his shirt collar size and round up to an even length.
Can I add a pendant to the chain later?
Yes, if the chain is a pendant-friendly style such as box, wheat, franco, or rope, and long enough: a pendant usually needs 22″ to 24″. Check that the pendant’s bail fits over the chain.
What if the chain is too short?
Exchange it for the next length up. A chain that feels tight won’t get worn, and chains can’t be stretched; keep the tags and packaging until he has tried it on.
Bottom line
If you can’t ask, buy 22″: it fits more necks than any other length, and a chain that sits a little low looks right while a tight one never gets worn. Better still, measure a chain he owns or add 4″ to 6″ to his collar size. Keep it 3 to 5 mm wide unless he already wears something heavier, choose a classic solid weave with a lobster clasp, and keep the tags until he has tried it on.
