The most common everyday necklace length is 18 inches (46 cm), which sits just below the collarbone and is called a princess length. A choker is shorter (about 14 to 16 inches), a matinee longer (about 20 to 24 inches) and an opera longer still (24 to 30 inches in one jeweller's chart). For a bracelet, measure your wrist just below the wrist bone, snug but not tight, and pick the bracelet size that matches, going up a size if you are between two. Charts from different jewellers disagree by an inch or two, so use the numbers below as a guide and check the actual length on the product page before you buy.
Necklace length chart
Necklace names describe where the chain falls, not a legal standard, which is why shops draw the lines in slightly different places. Blue Nile's necklace length chart, written by a GIA-credentialed jewelry professional, lists:
| Name | Length | Where it sits | Pairs with |
|---|---|---|---|
| Collar | 14 in (36 cm) or less | High on the neck, near the base | Off-the-shoulder tops, V-necks |
| Choker | 14 to 16 in (36 to 41 cm) | Around the base of the neck | Scoop or strapless necklines |
| Princess | 18 in (46 cm) | Just below the collarbone | Crew or boat necks |
| Matinee | 20 to 24 in (51 to 61 cm) | At or just above the bust | High necklines, button-down shirts |
| Opera | 24 to 30 in (61 to 76 cm) | Below the bust | Turtlenecks, evening dresses |
| Rope | 30 in (76 cm) and longer | Long chain, can be looped or doubled | Simple tops |
For comparison, Italo Jewelry's size guide names four standard looks: 17 in (43 cm) choker, 18 in (46 cm) princess, 20 in (51 cm) matinee and 22 in (56 cm) opera. So a "choker" is 14 to 16 inches at one jeweller and 17 at another, and an "opera" starts at 22 or at 24 inches. Always go by the length in inches or centimetres in the listing, not the name.
Choosing a necklace length
Blue Nile lists the things that change how a chain looks on you:
- Neck size. Shorter lengths can look more flattering on smaller necks; longer chains balance broader frames.
- Pendant size. Larger pendants pull a necklace lower.
- Chain thickness. Thick chains can look shorter.
- Neckline. Shorter necklaces suit open necklines, longer ones suit high necklines.
- Layering. To layer, Blue Nile suggests leaving about 2 inches between pieces, for example a 16-inch choker with an 18-inch pendant and a 20-inch chain.
On men's jewellery, Blue Nile notes that an 18-inch chain is considered a choker length, a 20 to 24-inch matinee sits on the upper chest, and a rope length falls mid-chest.
Bracelet size chart: measure your wrist
Brilliant Earth's bracelet size guide (updated July 2026) gives a wrist-to-bracelet chart for women's and men's bracelets. The bracelet size is the actual length of the bracelet.
| Your wrist | Your wrist in cm | Bracelet size |
|---|---|---|
| 5 to 5.5 in | 12.7 to 14.0 cm | 5.5 in |
| 5.6 to 6 in | 14.1 to 15.3 cm | 6 in |
| 6.1 to 6.5 in | 15.4 to 16.6 cm | 6.5 in |
| 6.6 to 7 in | 16.7 to 17.9 cm | 7 in |
| 7.1 to 7.5 in | 18.0 to 19.0 cm | 7.5 in |
Brilliant Earth gives the average bracelet length as 6.5 to 7 inches for women and 7.5 inches for men.
How to measure: wrap a flexible tape measure around your wrist just below the wrist bone, snug but not tight (you should be able to rotate it), and read the number where it meets the start. With no tape, use a string or ribbon, mark where it overlaps, lay it flat and measure it against a ruler. You can also lay a bracelet that already fits flat and measure its full length. A good fit lets you slide one finger between the bracelet and your skin.
Jewellers differ on how tight to measure. Italo Jewelry's size guide says to measure tightly above the wrist bone, round up, and then look up that design's own size table (its example maps a 7-inch wrist to a 17.75 cm bracelet for that style), and it warns that thick string can add 0.5 to 1 cm. If a listing has its own sizing, use that over any general chart.
Before you order
| Check | Why it matters |
|---|---|
| The length in inches or cm, not just "choker" or "princess" | Names vary between shops |
| Whether the length includes the clasp or extender | Check the listing; extenders add adjustable length |
| Pendant size and chain thickness | They change how long a chain looks |
| The shop's returns on chains and bracelets | Fit is hard to judge online; see our guide to buying jewelry online |
| Ring size, if buying a set | See how to find your ring size |
| Earring style and closures | See our earrings guide |
What to buy, if anything
Start from the length you already wear comfortably: measure a chain or bracelet that fits, or use your wrist measurement and the chart above. If you are unsure, a necklace with an adjustable chain gives you room, and for a bracelet choose the larger size when you are between two. Custom-sized and engraved pieces are often not returnable, so measure twice before ordering those; one online jeweller's policy, for example, excludes customised sizes from its 60-day returns.
