A chain that sits at the wrong height never looks right, no matter its quality. Length decides where the chain falls on the body — here is the complete chart and how to choose without guessing.
The length chart
| Length | Where it falls | Typical wearer |
|---|---|---|
| 16" | Base of the neck / choker-adjacent | Women (petite), children |
| 18" | Collarbone | Women's standard, teens |
| 20" | Just below collarbone | Women (longer), men (short/tight) |
| 22" | Above mid-chest | Men's standard |
| 24" | Mid-chest | Men's relaxed standard |
| 26"–30" | Below chest, maximum swing | Long pendants, layering, bold looks |
Women's lengths by neckline
18" at the collarbone is the universal women's length — right with crew necks, V-necks, and open collars alike. 16" suits higher necklines and petite frames; 20" works over sweaters and with lower necklines. If you own one chain, make it 18".
Men's lengths by build
22" is the safest men's length: it falls mid-chest on an average build and works both over and under a shirt. Broader or taller men often prefer 24"; 20" gives a tighter, higher look near the collar. When gifting, one size longer is safer than shorter — most jewelers can shorten a solid gold chain, but extending is harder.
Children's lengths
16" is the children's standard, moving to 18" in the teen years. For bautizo and First Communion medals, a 16" fine chain (1–2mm) fits the ceremony and the years after it.
Measuring at home
Take a chain that already sits where you like and measure it end to end, clasp included — that number is your length. No chain to copy? Run a string around the neck, let it hang to the spot you want, and measure the string.
