Short version: if you are buying an 8mm beaded bracelet and your wrist measures more than about 7 inches, the size our chart recommends is probably one size too small. Below is the arithmetic — taken from our own size chart and our own return records — and the measuring method we recommend instead.
The number that made us rewrite this page
Between 11 August 2025 and 11 August 2026 we logged 3,928 return reasons across our catalogue. 1,880 of them — 47.9% — were about size. That part is unremarkable. Sizing is the largest single return reason for almost every jewellery brand that sells online.
What is not unremarkable is the split:
- "Too Small" — 1,179 returns
- "Too Big" — 701 returns
A size chart that is simply imprecise misses in both directions at roughly the same rate. Ours misses in one direction 1.68 times more often than the other. That is not measurement noise from customers holding tape measures badly. That is a systematic bias built into the chart, and it is ours to explain.
Where the missing half inch goes
Here is the 8mm chart as it is currently published on our product pages:
| Size | Wrist circumference | Bracelet length |
|---|---|---|
| Small (S) | 6.0 – 6.5" | 7.5" |
| Medium (M) | 6.6 – 7.5" | 8.25" |
| Large (L) | 7.6 – 8.5" | 9.25" |
The problem is that a bracelet length and a wrist circumference are not the same kind of measurement, and the difference is not small.
When you lay a beaded bracelet flat and measure it end to end, you are measuring along the middle of the beads. But your wrist sits inside that circle of beads, against their inner surface. When the strand closes into a circle, the inner circumference is shorter than the measured length by roughly π × the bead diameter.
For an 8mm bead: 8mm is 0.315", and π × 0.315" = 0.99". Almost exactly one full inch disappears between the number on the chart and the space your wrist actually gets.
Apply that to the chart:
| Size | Length | Usable inner circumference | Largest wrist the chart sends here | Room left |
|---|---|---|---|---|
| Small | 7.5" | 6.5" | 6.5" | 0.0" |
| Medium | 8.25" | 7.25" | 7.5" | −0.25" |
| Large | 9.25" | 8.25" | 8.5" | −0.25" |
Read the last column. At the top of every single size band, the bracelet has zero room or negative room — it cannot close. At the bottom of each band it has a comfortable 0.5 to 0.65 inches. Every size in our chart fits the smallest wrist it is recommended to and fails the largest one.
That is precisely the shape of a chart that produces 1,179 "too small" returns and 701 "too big" returns.
A note on the arithmetic: the π × diameter figure is a geometric approximation. Real bracelets have a clasp, the beads are not perfectly spherical, and the strand does not form a perfect circle on a real wrist. We are not claiming three decimal places. We are claiming a direction and a magnitude — about an inch — and our return split is the evidence that the model is right about both.
Our customers described this before we calculated it
The arithmetic above is new. The complaint is not. These are published reviews on our own product pages, and they describe the same failure from the inside:
"Size is somewhat a problem. Regular too tight to clasp. Large fits loosely."
— Don Collins, Rutile Quartz 8mm
"Using the size chart, the smaller of the sizes that I am in between is much too small. Went with the next size up, and it's too big. It's gathering dust."
— Tom McGurk, Mother of Pearl 6mm
"The smaller size you offer was too small. This one is too big. The size increments in which you offer don't fit me."
— Cesar Romero, Blue Tiger Eye 8mm
And one review that, without meaning to, measured the flaw for us:
"I measured my wrist and it recommended the large but it is way too loose, maybe 3–4 beads too big."
— James Hoey, African Turquoise 8mm
An 8mm bead is 0.315". Three to four beads is 0.95" to 1.26" — and the step from our Medium to our Large is exactly 1.0". He counted the gap between two of our sizes, bead by bead, and got the same answer our chart gives.
The real problem: our steps are bigger than the target
A beaded bracelet with a clasp has a narrow window of lengths that actually work. Too tight and you cannot fasten the clasp one-handed — as one customer put it, "without any slack... I find it almost impossible to open and connect the latch." Too loose and it slides over your hand.
Reading across our reviews, that window is roughly 0.4" to 1.0" of clearance over your bare wrist. Call it 0.6" wide.
Our sizes step by 0.75" from Small to Medium, then 1.0" from Medium to Large. Worth noting: neither step is a whole number of beads — 0.75" is 2.4 beads and 1.0" is 3.2 beads, which tells you the lengths were not set from the bead up.
A 0.6" window and steps of 0.75" and 1.0" do not tile. Wrists land in gaps where neither adjacent size is right — one is tight, the next is loose. That is not a chart that needs better wording. That is a chart with structural holes in it, and it is why "I'm between sizes" appears in our reviews as often as it does.
How to measure your wrist — the method we recommend
Ignore the wrist column on the current chart. Use the length column instead, and get there like this:
- Wrap a tape measure around your wrist, just below the wrist bone, where the bracelet will sit. No tape measure? Use a strip of paper and mark it, then lay it against a ruler.
- Keep it relaxed, not snug. The current chart says "snug", and that alone costs you about 0.2". Let the tape rest on the skin without pressing in.
- Measure at the end of the day. Wrists swell a little; you want the bracelet to fit at the wrist's largest, not its smallest.
- Add your bead allowance to get your target bracelet length:
- 8mm beads: add 1.4" to 2.0" (about 3.5 to 5 cm)
- 6mm beads: add 1.15" to 1.75" (about 3 to 4.5 cm)
- Match your target length to the length column — not your wrist to the wrist column.
Worked example
A 7.0" wrist, buying an 8mm bracelet. 7.0" + 1.7" = 8.7" target length. Our Medium is 8.25" and our Large is 9.25". Neither is 8.7". This customer is exactly in the gap — and the current chart would confidently send him to Medium, half an inch short. Read on.
Corrected quick reference for 8mm
| Relaxed wrist | Order |
|---|---|
| 5.5 – 6.1" | Small (7.5") |
| 6.25 – 6.85" | Medium (8.25") |
| 7.25 – 7.85" | Large (9.25") |
| 6.1 – 6.25", 6.85 – 7.25", or above 7.85" | Ask for a made-to-length bracelet |
And for 6mm
| Relaxed wrist | Order |
|---|---|
| 5.35 – 5.95" | Small (7.1") |
| 6.25 – 6.85" | Medium (8.0") |
| 7.25 – 7.85" | Large (9.0") |
Yes, the gap rows cover a lot of men. We would rather tell you that than sell you a bracelet you cannot wear.
If you land between sizes, ask for a length
Our bracelets are strung by hand in our own workshop, which means a specific length is a request, not a special order. Customers do this regularly and write about it afterwards:
"I appreciate the custom size you were able to process. 7.75 inches exactly makes a huge difference."
— Jose Padilla, Howlite 8mm
"I asked that the bracelet be made to a specific size and it came out perfect."
— Eric Pitter, Tiger Eye 6mm
"I needed a size they didn't have and they were able to make it happen."
— Adam Wise
Put your target length in the order notes — in inches or centimetres, to the quarter inch. If you are unsure, give us your relaxed wrist measurement and the bead size, and we will do the arithmetic on this page for you.
6mm or 8mm? A correction
An earlier version of this page said that if you were caught between sizes on 8mm, the same stone in 6mm would often fit where the 8mm did not. That was wrong, and we are correcting it rather than quietly deleting it.
The reasoning looked sound — a 6mm bead consumes about 0.74" of circumference against 0.99" for an 8mm, so the smaller bead should buy back a quarter inch. But our 6mm strands are also cut shorter to match, and when you run the numbers the two cancel almost exactly:
| Size | 8mm inner circumference | 6mm inner circumference |
|---|---|---|
| Small | 6.51" | 6.36" (6mm is tighter) |
| Medium | 7.26" | 7.26" (identical) |
| Large | 8.26" | 8.26" (identical) |
So switching to 6mm buys you nothing in Medium or Large, and in Small it is actually 0.15" tighter. If you are between sizes, dropping to 6mm will reproduce the same problem — order a made-to-length strand instead.
Choose between 6mm and 8mm on how you want it to look, not on how you want it to fit. 6mm sits closer to the skin and stacks better with a watch; 8mm reads as a standalone piece.
One label we are going to change
On our best-selling bracelet, the middle size is currently labelled "Regular — Suitable for Most". Over the last twelve months, 65.8% of buyers chose it — 2,423 of 3,684 units.
Given everything above, that label is doing real damage. It reads as reassurance, it is the path of least resistance at checkout, and for a large share of the men choosing it, it is the wrong size. Two thirds of our customers picking the same option is not a coincidence about wrist sizes. It is a wording effect.
Start here
Measure first, then pick. These are the bracelets our sizing questions come up on most, all currently in stock:
- Tiger Eye Stone Spiritual Beads Bracelet — 8mm
- African Turquoise Stone Spiritual Beads Bracelet — 8mm
- Black Onyx Stone Spiritual Beads Bracelet — 8mm
- Malachite Stone Spiritual Beads Bracelet — 8mm
- Tiger Eye Stone Spiritual Beads Bracelet — 6mm (the 6mm alternative)
What we are fixing
Publishing this without changing anything would be worse than not publishing it. So, in order:
- The wrist bands on the size chart are being recalculated so that each size is quoted for the wrists it actually fits, rather than the wrists it fits at the bottom of the band.
- The word "snug" is coming out of the measuring instructions.
- "Regular — Suitable for Most" is being renamed to something that states a length instead of implying a verdict.
- We are looking at closing the gap between sizes, because no amount of better wording fixes a step that is wider than the target. The natural step is two beads — 0.63" — not the 0.75" and 1.0" we use today.
If you have already bought a bracelet that does not fit, that is on the chart and not on you. Contact us with your order number and your wrist measurement, and we will make it right.
