What is the most common necklace length?

In the US, 18 inches. It sits on or just below the collarbone on most adults and suits both a pendant and a plain chain.

How do I measure a necklace I already own?

Lay it flat in a circle with the clasp closed and measure the full loop with a ruler or tape, or lay it out straight, clasp included, and measure end to end.

Can a vintage chain be shortened or lengthened?

Shortening is usually straightforward. Lengthening depends on finding matching period links. We check both before quoting anything on a specific chain.

In short

US necklace lengths are quoted in inches and follow a conventional set of names: a collar sits at about 12 to 14 inches, a choker 14 to 16, princess 17 to 19, matinee 20 to 24, opera 28 to 36 and a rope longer than 36. These are trade conventions rather than standards, and where a chain actually falls depends on your neck and how you wear it, so measure a necklace you already like and use that number.

Length is the single most common reason a necklace bought online is sent back, and it is the easiest thing to get right. Two minutes with a piece of string will save you a return.

Antique European necklaces were not made to US length names, so treat the chart below as a translation rather than a rule. The measurement we publish for each piece is the real, measured length of that chain.

The chart

Conventional US names and the lengths usually meant by them. Where a chain falls on you depends on your height, neck and build, so read these as a starting point.

Collar, 12 to 14 in (30 to 36 cm): sits tight around the base of the neck
Choker, 14 to 16 in (36 to 41 cm): sits at the base of the throat
Princess, 17 to 19 in (43 to 48 cm): sits on the collarbone, the most common length
Matinee, 20 to 24 in (51 to 61 cm): sits between the collarbone and the bust
Opera, 28 to 36 in (71 to 91 cm): sits at or below the bust, can be doubled
Rope, over 36 in (over 91 cm): can be doubled, knotted or worn long

How to measure at home

Take a length of string or a soft tape, lay it around your neck and adjust until it falls exactly where you want a necklace to sit. Mark the point where it meets, lay it flat and measure it in inches. That number is the length to shop for.

If you are buying a pendant, add the drop of the pendant to your number. A 1 inch pendant on an 18 inch chain hangs where a 19 inch chain would.

Choosing a length for a pendant or locket

Heavier lockets and larger pendants generally look settled at princess or matinee length, where there is room for them to hang clear. Very short chains push a large pendant up against the collarbone and it will tip forward.

If you layer, leave at least 2 inches between chains so each one reads separately. Our layering guide covers this in more detail.

Vintage chains and length

Antique chains were often made longer than modern ones, because a long guard or muff chain was a functional object. Many have been shortened at some point in their life, which is normal and does not affect authenticity, though it can affect where a hallmark sits.

Lengthening a vintage chain is possible when we have period-appropriate links to match, and shortening is straightforward. Ask us before you buy and we will tell you what the specific chain allows.
