A jade bracelet can be one of four completely different things, and they are not sized the same way. A rigid bangle is measured by its inner diameter and has to clear your knuckles. A bead bracelet is measured by wrist circumference. A braided cord slides. A link bracelet fastens at a fixed length.
Getting this wrong is the single most common reason a jade bracelet is returned. So before you measure anything, look at the product photo and decide which of the four you are buying.
The short version:
- Rigid bangle — measure your hand at its widest point with the thumb tucked, divide by 3.14, subtract 4mm. That is your inner diameter.
- Bead or elastic bracelet — measure your wrist and add 1 to 2cm, depending on bead size.
- Braided cord bracelet — measure your wrist and check the adjustable range covers it.
- Chain, link or cuff — measure your wrist and add 1.5 to 2cm.
Every BMjade bangle is listed with its exact inner diameter in millimeters, and every strand bracelet with its inner circumference, so you can match a number rather than guess at small, medium or large. Browse jade bracelets and bangles once you know yours.
Part 1: Rigid Jade Bangles
Why inner diameter is the only number that matters
A traditional jade bangle is one continuous ring of stone. It does not open, hinge, stretch or resize — a solid bangle that is wrong is wrong forever. It also has to travel over the widest part of your hand before it reaches your wrist, which is why wrist size tells you almost nothing here. A person with a slim wrist and broad knuckles needs a larger bangle than their wrist would suggest.
Inner diameter is the straight-line distance across the inside of the bangle. A 1 to 2mm difference is clearly noticeable, which is why we publish ours to the decimal rather than in size bands.
How to measure: the hand circumference method
This is the method to use. It captures the whole three-dimensional shape of your compressed hand rather than one flat dimension, and it is the one that survives comparison with real fittings.
- Choose the hand you will actually wear the bangle on. Hands differ.
- Bring your fingers together and tuck your thumb across your palm so the tip reaches the base of your little finger. This is exactly the shape your hand makes when a bangle goes on.
- Wrap a soft tape or a strip of paper around the widest point of that compressed hand, across the knuckles and over the thumb joint. Snug, not tight.
- Mark the overlap and measure the length in millimeters.
- Repeat twice more and take the middle result.
Then apply the formula:
Inner diameter = hand circumference ÷ 3.14 − 4mm
Dividing by 3.14 gives the diameter of a circle with the same circumference as your hand. Your hand is not a circle and it compresses, so the bangle you actually need is a few millimeters smaller than that figure. Subtracting 4mm gives a standard fit. Subtract 6mm for a close traditional fit, or only 2mm if you want it to come off easily.
Jade bangle size chart
| Hand circumference | Close fit | Standard fit | Relaxed fit |
|---|---|---|---|
| 165 mm / 6.5 in | 46.5 mm | 48.5 mm | 50.5 mm |
| 170 mm / 6.7 in | 48.0 mm | 50.0 mm | 52.0 mm |
| 175 mm / 6.9 in | 49.5 mm | 51.5 mm | 53.5 mm |
| 180 mm / 7.1 in | 51.5 mm | 53.5 mm | 55.5 mm |
| 185 mm / 7.3 in | 53.0 mm | 55.0 mm | 57.0 mm |
| 190 mm / 7.5 in | 54.5 mm | 56.5 mm | 58.5 mm |
| 195 mm / 7.7 in | 56.0 mm | 58.0 mm | 60.0 mm |
| 200 mm / 7.9 in | 57.5 mm | 59.5 mm | 61.5 mm |
| 205 mm / 8.1 in | 59.5 mm | 61.5 mm | 63.5 mm |
| 210 mm / 8.3 in | 61.0 mm | 63.0 mm | 65.0 mm |
Most adult women land between 52 and 58mm. Most adult men land between 58 and 64mm. If your measurement falls between two rows, interpolate rather than rounding to the nearest — a millimeter is a real difference on a bangle.

The more accurate check: measure a bangle you already own
If you have a bangle that fits the way you like — yours, your mother's, a friend's — measure the inside of it with a ruler or calipers, edge to edge across the opening, and order that number. This beats every calculation, because it accounts for how flexible your particular hand is.
Two cautions. Measure the inside, not the outside; the outside includes the wall thickness and will send you a size too large. And metal bangles are usually worn looser than jade, so a gold bangle that fits comfortably is not a reliable target.
Band width changes the fit
Two bangles with the same inner diameter do not feel the same if one is a slim 7.5mm band and the other a 12mm traditional band. A wider band has more contact with your skin on the way over the knuckles and reads tighter.
If you are choosing a wide-band bangle and you are between sizes, take the larger. On a slim band you can take the smaller.
Round profile or flat profile? It changes the fit too
Band width is not the only thing that makes two bangles of the same inner diameter feel different. Profile does too, and almost nobody mentions it.
Flat profile (扁条) — the band has a flat or gently curved inner surface and squared-off edges. It sits against the wrist with more contact area, feels more stable, and is the more common modern shape. Because more of the band touches your hand on the way over the knuckles, a flat-profile bangle reads slightly tighter at the same inner diameter.
Round profile (圆条) — the band is round in cross-section, like a rod bent into a circle. It rolls over the knuckles rather than dragging across them, so it goes on more easily at the same measurement. It is the older traditional shape, uses more rough per bangle, and is usually the more expensive of the two for that reason.
What to do with this:
- Moving from a flat-profile bangle to a round-profile one at the same inner diameter, expect it to feel slightly looser.
- If you are between sizes and choosing a flat profile, take the larger.
- If you are between sizes and choosing a round profile, the smaller will usually still pass.
- If you already own a bangle that fits perfectly, note its profile as well as its inner diameter when you shop for the next one.
The difference is small — roughly half a millimeter of felt fit — but on a piece where two millimeters is the gap between sizes, half a millimeter is worth knowing.

Round bangles and oval Guifei bangles
A round bangle has one inner diameter and passes over the hand evenly. It is the easiest style to size and the right first bangle.
An oval Guifei bangle has a long and a short inner diameter. It sits flatter against the wrist and many people find it more comfortable to wear, but it is more sensitive to fit, because the hand has to pass through the short axis. When a Guifei bangle is listed, check both figures, and compare the short diameter against the chart above rather than the long one.
How to put a jade bangle on
Even a correctly sized bangle takes a moment to go on the first time. Never force it.
- Slip a thin plastic bag over your hand, or wet your hand with soap and warm water.
- Tuck the thumb into the palm and press the fingers together.
- Work the bangle over the knuckles with a slow rocking motion, not a straight shove.
- Do it over a bed or a sofa, never over a tile floor or a sink.
If it will not pass with lubricant and patience, it is too small. Stop.
How to tell the size is wrong
Too small: it will not clear the knuckles with lubricant; it hurts going on; the hand goes red or numb; you cannot get it off at the end of the day.
Too large: it slides past the wrist bone and swings down the forearm when your arm is raised; it knocks against desks, door handles and car doors during ordinary movement. This is the more dangerous failure. Most broken bangles are broken because they were too big, not because they were too tight.
A correctly sized bangle is snug across the knuckles and then moves an inch or so freely on the wrist.
If a bangle is stuck: how to get it off safely
This is the situation nobody plans for, and panic makes it worse. Work through this in order.
First, check for a real problem. If the hand is turning purple, blue or white, if it feels numb or tingling, or if the fingers are visibly swelling, stop reading and treat it as urgent — elevate the arm above your head, apply something cold to the hand, and if it does not improve within a few minutes, go to an urgent care clinic or emergency department. A jewelry shop or a fire station can cut a bangle off. Any bangle can be replaced. Circulation cannot wait.
If there is no numbness or discolouration, you have time. Then:
- Elevate first, for five to ten minutes. Lie down with the arm straight up, or rest it above your head. Most stuck bangles are stuck because the hand is swollen, and elevation alone often resolves it.
- Cool the hand. Cold water or a cool pack for a few minutes reduces swelling further. Not ice directly on the skin.
- Lubricate generously. Soap, hand cream, conditioner, or cooking oil. More than feels necessary.
- Use a plastic bag. Slip a thin plastic bag over the hand — this is the single most effective trick, because it gives the bangle a slick surface to travel over instead of skin.
- Compress and rock. Tuck the thumb deep into the palm, press the fingers tightly together, and work the bangle off with a slow rocking motion, alternating sides. Do not pull straight.
- Do it over something soft. A bed or a sofa. A bangle that comes off suddenly over a tiled floor breaks.
When to stop trying. If it will not come off after two patient attempts with lubricant and a bag, leave it and try again in the evening or the following morning — hands change size through the day and with the weather. Repeated forcing swells the hand further and makes the next attempt harder.
Timing matters. Hands are smallest in the morning and in cool conditions, largest in the evening, in heat, after salty food, after alcohol, during flights, and in pregnancy. If a bangle that normally fits has become tight, the hand has changed rather than the stone.

Part 2: Jade Bead and Elastic Bracelets
Bead bracelets are sized by wrist circumference, not by hand width, because they are strung on elastic or knotted cord and go on over the wrist rather than the knuckles.
How to measure your wrist
Wrap a soft tape around your wrist just below the wrist bone, where the bracelet will sit. Keep it snug against the skin without compressing it. Record in centimeters or inches.
Bead bracelet size chart
A strand has to be longer than your wrist, because the beads themselves take up room on the inside of the circle. The larger the bead, the more length you need for the same wrist.
| Wrist | Beads up to 8 mm | Beads 10–12 mm | Beads 14 mm and over |
|---|---|---|---|
| 14.0 cm / 5.5 in | 15.0–15.5 cm | 15.5–16.0 cm | 16.0–16.5 cm |
| 15.0 cm / 5.9 in | 16.0–16.5 cm | 16.5–17.0 cm | 17.0–17.5 cm |
| 16.0 cm / 6.3 in | 17.0–17.5 cm | 17.5–18.0 cm | 18.0–18.5 cm |
| 17.0 cm / 6.7 in | 18.0–18.5 cm | 18.5–19.0 cm | 19.0–19.5 cm |
| 18.0 cm / 7.1 in | 19.0–19.5 cm | 19.5–20.0 cm | 20.0–20.5 cm |
| 19.0 cm / 7.5 in | 20.0–20.5 cm | 20.5–21.0 cm | 21.0–21.5 cm |
The rule behind the table: add about 1cm for small beads, 1.5cm for medium, 2cm for large.
About the elastic
An elastic strand stretches, which is why it forgives a few millimeters either way and why it is the safer choice as a gift. It is not unlimited. Stretching a strand hard every time you put it on fatigues the cord, and a jade bead bracelet that snaps scatters the beads.
Roll it on rather than pulling it over a clenched fist, and if a strand has stretched permanently loose after a year of wear, have it restrung rather than living with it.

Part 3: Braided and Adjustable Cord Bracelets
Hand-braided jade bracelets usually close with a sliding knot: two knots that travel along the cord and lock where you leave them. The braid moves in both directions, so one piece covers a range of wrist sizes rather than a single measurement.
Check that the listed adjustable range covers your wrist measurement with room at both ends — you want to sit in the middle of the range, not at the far end of it, so the knot has somewhere to go when your wrist changes with heat or exercise.
To tighten, hold the bracelet and pull the two loose cord ends outwards. To loosen, pull the two sides of the loop apart. Cord relaxes slightly with wear; re-tighten it rather than assuming it has become the wrong size.
Part 4: Chain, Link and Cuff Bracelets
Chain and link bracelets fasten at a fixed length. Measure your wrist and add 1.5 to 2cm for a comfortable everyday fit — enough that the bracelet moves and does not press into the wrist bone. Heavier link styles, including Cuban link, sit better with the full 2cm; men's link bracelets are commonly worn with 2 to 2.5cm of ease. If a bracelet comes with an extender chain, the listed length is the shortest setting.
Cuffs are open bands with a gap. The stated measurement is usually the length of the metal or stone, not a full circle, and the gap makes up the difference. A cuff is easier to put on than a bangle and holds its shape better than a strand, which makes it a reasonable middle option when you cannot measure the wearer's hand.
Sizing for Someone Else, Without Asking Them
The hardest version of this problem: you want to give a jade bangle, and asking the recipient to wrap a tape around their hand ruins the surprise.
The best method — measure a bangle they already wear. If they own a bangle, a rigid cuff, or even a fixed-size metal bracelet that fits well, measure its inner diameter with a ruler while they are not wearing it. This is more reliable than any measurement you could take of their hand.
Second best — the paper strip, disguised. Ask them to help you with something that requires their hand to be measured: a glove size, a costume, a craft project. Wrap a strip of paper around the compressed hand, mark the overlap, then apply the formula later.
Third — compare to your own hand. If your hands are similar in size, measure yourself, then adjust: a hand that looks noticeably broader than yours across the knuckles is usually 5–10 mm larger in circumference, which is 2–3 mm of inner diameter.
Honest advice: if none of these is possible, do not buy a rigid bangle. Buy a bead bracelet, a braided cord, or a cuff, and let them choose a bangle later with their own measurement — we will hold a piece while a size is confirmed. A gift that does not fit and cannot be resized is not a kindness, and a bangle bought a size too large is the version most likely to be broken within a year.
Sizing for children and teenagers. Only elastic bead bracelets. A child's hand grows, a rigid bangle does not, and a bangle sized to be grown into is a bangle that swings and breaks. Wrist plus about 1 cm, restrung as they grow.
Which Structure Should You Choose?
| Situation | Best choice |
|---|---|
| You can measure the wearer's hand accurately | Rigid bangle |
| You want the traditional heirloom form | Rigid bangle |
| Buying a gift, size unknown | Bead bracelet, braided cord, or cuff |
| Your knuckles are much larger than your wrist | Bead bracelet or cuff |
| Your hands swell in heat, on flights or during the day | Braided adjustable, or a relaxed-fit bangle |
| First jade purchase, and you want to be sure | Bead bracelet |
| You travel often and take jewelry on and off | Bead or chain bracelet |
| Buying for a child | Elastic bead bracelet only |
A rigid bangle is the piece worth measuring properly for. Everything else is forgiving, and there is no shame in choosing the forgiving one.
Common Sizing Mistakes
Measuring the wrist for a bangle. The bangle has to clear the hand first. Wrist size is the right measurement for beads, cord, chain and cuffs, and the wrong one for bangles.
Measuring an open, flat hand. Your hand is narrower when the thumb is tucked in and the fingers are pressed together. Measure it in the shape it will actually be.
Dividing by 3.14 and stopping there. That figure is the circle equivalent of your hand. Because the hand compresses, the bangle you need is smaller than it — subtract 4mm. Adding to it is the most common way to end up with a bangle that slides off.
Measuring the outside of a bangle you own. The wall thickness is not part of the fit.
Buying the smallest size that theoretically works. A very tight fit is a tradition, not a requirement, and it is a poor choice for a first bangle.
Buying a size too large "to be safe." Loose bangles are the ones that break. Relaxed means two millimeters, not five.
Ignoring band width. A 12mm band at 56mm feels tighter than a 7.5mm band at 56mm.
Ignoring profile. A flat-profile band drags where a round one rolls. Half a millimeter of felt difference, on a piece where two millimeters separates sizes.
Measuring in the morning, or straight after exercise. Hands change through the day. Measure in the evening at a normal temperature, and average three readings.
Before You Order: A Checklist
- The structure is clear — bangle, bead, cord, chain or cuff
- For a bangle, the inner diameter is listed as an exact number, not a size band
- For a bangle, the band width is listed
- For a bangle, the profile is stated — round or flat
- For a strand, the inner circumference and bead diameter are listed
- For an adjustable piece, the full range is listed
- The material is named specifically: jadeite or nephrite
- Treatment status is stated, with a certificate you can verify by serial number
- The photographs show the actual piece you will receive
- The return window and the exchange process are clear before you buy
Materials: What "Type A" Does and Does Not Mean
Two different minerals are correctly called jade, and they are graded differently.
Jadeite is graded A, B and C by treatment. Type A means natural jadeite that has not been bleached, resin-impregnated or dyed. It is the only category worth buying, and it is the only one we sell.
Nephrite — including Hetian jade from Xinjiang — does not use the A/B/C system at all. A nephrite piece is described as natural and untreated, meaning undyed and not wax-coated. If a seller advertises "Type A" nephrite, they are either confused or hoping you are.
BMjade carries both, and every piece ships with an independent gemological report carrying a serial number you can verify on the laboratory's own site. Our lifetime authenticity guarantee covers both minerals on their own terms: if any qualified independent lab ever finds a piece is not the material or treatment status we described, we refund the purchase price and reimburse your testing fee and return shipping, with no time limit.
Why Bangle Sizing Is Unforgiving — and Why That Is the Point
It is worth understanding why this one piece of jewelry demands a measurement when almost nothing else does.
A jade bangle cannot be resized because it is a single continuous piece of stone with no join to open and no metal to stretch. Jade is exceptionally tough — nephrite is the toughest natural gem material known, and jadeite is not far behind — but toughness is resistance to breaking, not the ability to deform. The stone will not give. Your hand has to.
That constraint is also the reason a bangle carries the meaning it does. A ring can be sized up as you age. A necklace fits everyone. A bangle is committed to one wrist from the moment it is cut, which is why it is the jade form that gets passed down rather than traded, and why the measurement is worth taking three times.
GIA notes that with fashioned jadeite, <a href="https://www.gia.edu/jade-quality-factor" target="_blank" rel="noopener">the value of bangle bracelets rises with size</a>, all other quality factors being equal — a larger bangle requires a larger, cleaner piece of rough, and rough that size is rarer. So a bangle is not only unresizable; a size you did not intend to buy is also a price you did not intend to pay. One tape measure, three readings, five minutes.

FAQ
How do I know my jade bangle size?
Wrap a tape around your hand at its widest point with the thumb tucked into the palm, measure in millimeters, divide by 3.14 and subtract 4mm. That is your inner diameter for a standard fit.
Is jade bangle size the same as wrist size?
No. A rigid bangle has to pass over your knuckles, so hand measurement decides the size. Wrist size is what you measure for bead, cord, chain and cuff bracelets.
Should a jade bangle be tight or loose?
Snug across the knuckles going on, then free to move an inch or so on the wrist. It should not need force, and it should not swing down your forearm when you raise your arm.
What if I am between two sizes?
Take the larger if the band is wide, if the profile is flat, if your knuckles are prominent, if your hands swell, or if this is your first bangle. Take the smaller if the band is slim, the profile is round, and your hands are flexible. The gap between two adjacent sizes is 1 to 2mm, not more.
Can a jade bangle be resized?
No. It is a single piece of stone with nothing to cut or stretch. This is why the measurement matters more here than on any other piece of jewelry, and why we suggest a bead bracelet or a cuff whenever the wearer's hand cannot be measured.
Are oval Guifei bangles sized differently?
Yes. Check both the long and the short inner diameter, and size against the short one, because that is the axis your hand has to pass through.
Does a round bangle fit differently from a flat one?
Slightly. A round-profile band rolls over the knuckles and goes on more easily than a flat-profile band of the same inner diameter, which drags across more surface. If you are between sizes, take the larger in a flat profile and the smaller in a round one.
My jade bangle is stuck. How do I get it off?
Elevate the arm for five to ten minutes, cool the hand, lubricate generously with soap or oil, slip a thin plastic bag over the hand, then tuck the thumb into the palm and work the bangle off with a slow rocking motion over a bed. If the hand is numb, tingling, or changing color, do not keep trying — elevate, cool, and seek medical help. The bangle can be cut off and replaced; circulation cannot wait.
Why does my bangle fit some days and not others?
Hands change size through the day and with conditions. They are smallest in the morning and in cool weather, and largest in the evening, in heat, after salty food or alcohol, during flights, and in pregnancy. A bangle that normally passes and suddenly will not is telling you about your hand, not about itself.
What size bead bracelet should I order?
Your wrist measurement plus about 1cm for beads up to 8mm, 1.5cm for 10–12mm beads, and 2cm for beads of 14mm and over.
What is the best jade bracelet to buy as a gift?
An elastic bead bracelet or a braided adjustable cord. Both forgive a few centimeters, and neither requires you to ask the recipient to measure their hand.
How do I buy a jade bangle as a gift without asking their size?
Measure the inside of a bangle or rigid bracelet they already wear — that is the most reliable method by far. If you cannot, buy a bead bracelet, braided cord, or cuff instead. A rigid bangle cannot be resized, and a guessed size is the most common reason a jade gift is returned.
What size jade bracelet should a child wear?
An elastic bead bracelet only — wrist measurement plus about 1 cm, restrung as they grow. A rigid bangle sized to be grown into will swing on the wrist and is the version most likely to break.
My bangle arrived and it does not fit. What now?
Contact us within the 30-day window with the piece unworn and in its packaging, and we will exchange it for a size that does. Do not attempt to force it on in the meantime.
Can a broken jade bangle be repaired?
Often, yes — a clean break can be joined with a metal band or converted into a different piece. See our bangle repair service.
Final Thoughts
Almost every jade bracelet sizing problem comes from applying bangle logic to a bead bracelet, or wrist logic to a bangle. Decide which structure you are buying, take the one measurement that structure needs, and use the numbers on the product page rather than a size label.
