Necklace lengths are given in centimeters, measured end to end. The number is useful but not decisive: a 45cm chain that lands below the collarbone on one person can sit at the base of the throat on someone else. What you are choosing is a position on the body.
The four standard lengths
Almost every necklace falls into one of four bands.
- Choker — about 35–40cm. Sits at the base of the throat. Usually worn alone, or as the shortest layer of a stack.
- Princess — about 45–50cm. Lands on or just below the collarbone. The length most people reach for, and the one that suits the widest range of necklines.
- Matinee — about 55–60cm. Drops onto the upper chest, over a sweater or into a deeper neckline.
- Opera — about 70cm and up. Falls below the bust. Wear it long, or loop it once for a shorter look.
If you are buying a first piece and cannot decide, buy princess. It works over a t-shirt, a shirt and a dress, and a second chain can be built around it later.
Measure a necklace you already own
The most reliable way to pick a length is to copy one that already works. Lay a necklace you wear often flat on a table, fully unclasped, and measure end to end including the clasp. That number is the length — not the distance from your neck to the pendant, because the chain travels around the back of your neck.
To test a length before buying, cut a piece of string to the same measurement and hold it at the back of your neck so the ends fall where a chain would, then move it up and down a few centimeters to see where a pendant would sit.
Match the length to the neckline
The neckline often decides more than the chart does. A chain should not follow the same line as the fabric.
- Crew or round neck. Princess or matinee length breaks the curve instead of echoing it.
- Deep v-neck. A pendant falling inside the V, usually at princess length, finishes the neckline.
- Collared shirt. A choker sits above the collar and reads as an accessory. A princess chain disappears under it by mid-morning.
- Turtleneck or high neck. Keep it short and let the knit texture do the rest. Long chains slide to one side over thick fabric.
- Off-shoulder or wide scoop. A choker or a short matinee gives the most balance against bare skin.
Height, frame and face shape
Height is the biggest variable: a chain sits higher on a taller person, so add around 5cm to the length you were considering if you are tall, and take around 5cm off if you are petite.
Frame matters too. On a narrower frame a statement pendant takes up more of the chest, so a shorter chain is often enough; on a broader frame the same pendant can look smaller than expected, and one band lower restores the balance.
Face shape is a softer guide. A choker draws the eye to the jaw and neck, while a longer chain with a pendant creates a vertical line.
Where the pendant should land
A pendant is a fixed point, so it decides the length more than the chain does. On most people it looks right just below the collarbone or in the middle of the upper chest — not directly on the bone, and not at the widest part of the bust.
If a pendant hangs too low, change the chain. A round onyx pendant on a short chain sits close to the throat; a crescent or crucifix shape on a fine chain usually reads clearly at princess length.
Common mistakes
- Buying to a number instead of a position. Check where the chain lands on you.
- Ignoring what you wear it with. Test the chain over the fabric it will actually sit on.
- Forgetting the extender. 5cm moves a chain into the next band, which helps if you are between sizes.
- Two chains at the same height. Leave at least 5cm between layers. Our guide on how to layer necklaces without tangling covers the rest.
Frequently asked
What length should I buy first?
Princess, roughly 45–50cm. It suits most necklines and works alone or as the middle layer of a stack.
How do I measure my neck for a choker?
Wrap a soft tape measure around the base of your throat, then add 2–3cm for comfort. A choker should sit flat without pressing in.
Can I shorten a necklace I already own?
Often yes — a jeweler can remove links or move the clasp. An extender only adds length, so buy the shorter chain and adjust upward.
Does a longer chain suit a tall person?
It usually helps. Add around 5cm to your intended length and check the position in a mirror.
