How to Measure Your Wrist for a Bracelet

Fine Jewelry

The measuring takes thirty seconds. The allowance afterwards is where people order the wrong length — and it is different for every style.

Short answer

Wrap a strip of paper snugly around your wrist just below the wrist bone, mark where it overlaps, and measure the strip in millimetres. That is your wrist measurement, not your bracelet size. Then add the allowance for the style: roughly 15–20 mm for a tennis bracelet, 20–25 mm for a chain. A bangle is not measured this way at all.

Bracelets are returned for length more often than for any other reason, and almost always because someone measured correctly and then ordered the number they measured. The wrist measurement is an input. The bracelet length is the wrist measurement plus an allowance, and the allowance depends entirely on what the bracelet is.

The measurement itself

Cut a strip of paper about a centimetre wide, or use a soft tailor's tape.
Wrap it around the wrist just below the wrist bone, on the hand side of it. That is where a bracelet actually sits.
Snug, not tight. It should touch the skin all the way round without compressing it.
Mark where the end overlaps, lay the strip flat and read it in millimetres.
Measure twice, ideally at different times of day.

That last point is not fussiness. Wrists swell with heat, salt and exercise, and in a hot or humid climate the difference across a day is easily two or three millimetres. Measure at the warmest part of the day and you will never own a bracelet that is comfortable in December and tight in June.

The allowance, by style

Style	Add to wrist measurement	Why
Tennis bracelet	15–20 mm	A stone-set line has almost no drape; too much slack lets it roll and show its underside
Chain or link bracelet	20–25 mm	Flexible links are meant to move; a close fit looks tight rather than fitted
Charm bracelet	25–30 mm	Charms hang below the wrist and shorten the effective circumference
Cuff (open)	5–10 mm, plus the gap	Sits on the wrist rather than around it; the opening does the rest
Bangle (closed)	Not applicable	Measured across the widest part of the hand instead — see below

A bangle is a completely different measurement

A closed bangle has to pass over the hand, so the wrist is irrelevant. Tuck your thumb into your palm as if you were putting a bangle on, and measure around the widest part of the hand — usually across the knuckles with the thumb folded in. That number, plus a few millimetres, is the internal circumference you need.

People routinely measure their wrist, order a bangle to it, and find it will not go on at all. There is no adjustment available afterwards: a closed bangle cannot be lengthened.

The five things that go wrong

Measuring over a sleeve or a watch strap. Skin only.
Pulling the tape tight. A millimetre of compression becomes a bracelet that marks the wrist.
Double conversion. Measuring in inches, converting to centimetres, then converting back. Take one measurement in millimetres and send that number.
Copying the length of an old bracelet. Clasps stretch and links wear; an old bracelet that fits well may be a length that no longer matches its own stated size.
Forgetting the clasp. This is the one nobody catches — see below.

From the workshop

Two bracelets both described as seven inches can sit differently on the same wrist, because workshops do not agree on whether the stated length includes the clasp. A box clasp with a figure-eight safety adds roughly eight to twelve millimetres of its own, and on a tennis bracelet that is the entire difference between fitted and loose. Ask any seller one question before you order: is the stated length measured including the clasp, or is the clasp extra? We measure ours end to end with the clasp closed, and we would rather be asked than assumed.

Fixed length, or an extender?

An extender chain of 20–25 mm solves several problems at once: seasonal swelling, uncertainty when a bracelet is a gift, and the fact that most people prefer a slightly different fit on a stone-set piece than on a chain. On a tennis bracelet it also gives you somewhere to attach a safety chain.

The argument against is aesthetic: on a fully set line, a plain extender is visible when it is in use. If the bracelet is for someone whose wrist you cannot measure, take the extender anyway. A piece that can be worn immediately beats a perfect length that arrives wrong.

Before you order

Measure in millimetres, at the warmest part of the day, twice.
Add the allowance for the specific style, not a general one.
Ask whether the stated length includes the clasp.
For a bangle, measure across the hand with the thumb tucked in — never the wrist.
If it is a gift, choose an extender or a style that tolerates a range.
Send the number in millimetres. Inches and sizes travel badly between countries; measurements do not.

Questions people ask

How do I measure my wrist for a bracelet at home?

Wrap a strip of paper or a soft tape snugly around the wrist just below the wrist bone, mark the overlap, and measure it flat in millimetres. Then add the allowance for the bracelet style you are buying.

What is the standard bracelet length?

Seven inches is the commonest stated length for women's bracelets and eight inches for men's, but a standard length is only a guess at your wrist. Measure and add the allowance rather than ordering the default.

Should a tennis bracelet be loose or fitted?

Fitted, with roughly a fingertip of movement. A stone-set line has very little drape, so excess length lets it rotate and show the gallery instead of the stones. It should slide around the wrist but not down over the hand.

Can a bracelet be shortened or lengthened later?

A chain bracelet can usually have links removed or added. A fully set tennis bracelet can have segments removed by a bench, which is more involved and changes the total stone count. A closed bangle cannot be altered at all.

How do I measure someone else's wrist for a surprise gift?

Measure a bracelet they already wear, laid flat and including its clasp, and note the style. Failing that, choose a piece with an extender chain or a cuff, both of which tolerate a range instead of demanding a number.
