Measuring Your Wrist - The Short Version
- Best method: a paper strip and a ruler. Paper does not stretch, which is why it beats string.
- Where to measure: just past the wrist bone, on the hand side - where a bracelet actually sits.
- How tight: snug against skin without compressing it. Pulling adds error, not accuracy.
- Then add: 0.5 inches for cord and leather, 0.75 to 1 inch for chain.
- No tools at all: a US dollar bill is 6.14 inches; a credit card is 3.37 inches.
- The shortcut: Infinity and Eros cuffs need no measurement - the wearer presses them to fit.
To measure your wrist for a bracelet, wrap a strip of paper around it just past the wrist bone, mark where the ends overlap, then lay the strip flat against a ruler. That measurement is your wrist circumference. Add half an inch for a cord or leather bracelet, or three quarters to one inch for chain. Most adult men measure between 6.5 and 8 inches, with 7 inches being the average - Caligio size M, which roughly 60 percent of our buyers order.
Measuring a wrist takes about ninety seconds and needs nothing you do not already have in the room. The reason it still goes wrong is that three small decisions inside those ninety seconds each shift the number by a quarter inch, and they compound.
Here are five methods ranked by how accurate they actually are, the three decisions that decide whether your number is right, and what to do with it once you have it.
The Quick Answer
Wrap a paper strip around your wrist just past the wrist bone, mark the overlap, and measure the marked length against a ruler. Keep the strip snug without compressing skin. Then add 0.5 inches for cord or leather, or 0.75 to 1 inch for chain, to get bracelet length. Caligio sizes run S to 6.7", M to 7.2", L to 8", XL lines to 9", and Infinity and Eros cuffs skip measuring entirely. New here? The code BLOG adds a reader bonus at checkout.
The Three Decisions That Decide Accuracy
Before the methods, the variables. Every measuring mistake in this category comes from one of three places, and none of them is the tool.
Where you wrap. Measure on the hand side of the wrist bone, where a bracelet naturally settles. Move an inch up the forearm and you gain a quarter to half an inch of circumference, which is a full size.
How hard you pull. The strip should sit against the skin without denting it. Pulling tight feels precise and produces a number that is too small, which is the single most common way men end up with a bracelet they cannot wear.
When you measure. Most people measure a quarter inch larger in the evening than first thing in the morning, and larger again after training or a salty meal. If you land exactly on a size boundary, measure twice at different times of day.
Method 1: The Paper Strip (Most Accurate)
A strip of paper is the most accurate no-tool method, and it beats string for one reason: paper does not stretch. Any elastic in the material transfers directly into a smaller reading.
- Cut or tear a strip about half an inch wide and a few inches longer than you expect your wrist to be. Receipt paper or a page edge both work.
- Wrap it around the wrist just past the wrist bone, flat against the skin, without pulling.
- Mark with a pen exactly where the free end crosses the strip.
- Unwrap, lay it flat along a ruler, and read from the end to the mark. That is your wrist circumference.
- Add 0.5 inches for cord or leather, 0.75 to 1 inch for chain, to get bracelet length.
Legacy - Why the Measurement Matters Here
Fixed sizes, cut properly: S to 6.7", M to 7.2", L to 8".
Legacy is thick round-woven leather on a 316L box-and-tongue clasp engraved CALIGIO inside, 17 grams, $59. It is the kind of build where the paper-strip method earns its ninety seconds: a structured braid is cut to a fixed length, so the size you choose is the size you keep for years. S covers wrists to 6.7 inches, M to 7.2, L to 8. Keep leather dry.
Shop LegacyMethod 2: String or Floss
String works if it does not stretch. Cotton twine, dental floss and kitchen string are all fine; elastic thread, yarn and shoelaces are not, because each one gives under light tension and quietly shortens your reading.
The procedure is identical to paper: wrap, mark or pinch the overlap point, then measure against a ruler. The extra risk is that string slides along itself while you unwrap, so pinch the point firmly and do not let go until it is flat.
Method 3: A Flexible Tape Measure
A sewing tape measure is the most accurate method overall and needs no conversion step at all - wrap, read, done. If you own one, use it.
One caution: a stiff carpenter tape does not work. It cannot follow the oval of a wrist, so it reads short on the flat sides and gives a number roughly a quarter inch under the truth.
Fortune - Cord That Keeps Your Number
Marine rope does not stretch, so the size you order stays the size you wear.
Fortune is marine-grade rope closed with a 316L steel shackle, $39. The same property that makes non-stretch string a good measuring tool makes marine rope a good bracelet: it holds its length under tension and through water, so a correct measurement stays correct a year later. Rope and steel are both waterproof, so this one does not come off at the beach.
Shop FortuneMethod 4: Your Phone
Phone measuring apps read flat distances rather than circumference, so they cannot measure a wrist directly. What a phone can do is give you a scale reference.
Photograph your wrist beside a standard credit card, which is 3.37 inches long, then compare the wrist width in the photo to the card. Multiply the width by roughly 2.8 for an approximate circumference. It is the least accurate method on this page and belongs to situations where you genuinely have nothing else.
Method 5: No Tools At All
Two objects in most wallets are precise enough to measure a wrist, because both are manufactured to fixed dimensions.
| Object | Known length | How to use it |
|---|---|---|
| US dollar bill | 6.14 inches | Wrap around the wrist and read where the end overlaps against the bill's own length |
| Credit card | 3.37 inches long | Lay end over end around the wrist, counting card lengths |
| Standard printer paper | 11 inches long edge | Tear a strip from the long edge and use it as a pre-measured ruler |
| Phone charging cable | Varies - measure once | Mark the wrist point, then compare to anything of known size later |
The dollar bill is the best of these. Wrapped around an average 7-inch male wrist it comes up short by about seven eighths of an inch, and that gap is easy to estimate against the bill's own printed width.
How the Five Methods Compare
| Method | Typical error | Needs | Verdict |
|---|---|---|---|
| Paper strip | Within 1/8" | Paper, pen, ruler | Best no-tool method |
| Sewing tape | Within 1/8" | A tape measure | Best overall if you own one |
| Non-stretch string | Around 1/8-1/4" | String, ruler | Good, watch for slipping |
| Known object | Around 1/4" | A dollar bill | Fine for choosing S, M or L |
| Phone photo | 1/4" or more | A phone and a card | Last resort |
Pulling the strip tight feels precise and gives you a number that is too small. That single instinct causes more unwearable bracelets than any tool.
Measuring for Someone Else
The most reliable way to size a gift is not to measure the person at all. Measure a bracelet or watch strap they already wear: lay it flat, read the inside length end to end, and order that length.
If they own neither, order size M. It covers roughly 60 percent of Caligio buyers, which makes it the highest-probability guess available. And if you want to remove the guess completely, there is a category of bracelet that solves it structurally.
Infinity - Fits Anyone, No Number Needed
Genuine exotic leather on a shaped 316L cuff, $77.
Infinity wraps genuine python or stingray around a 316L steel core, $77 across 21 builds. A 6.5-inch wrist presses the band closer, an 8-inch wrist opens it wider, and the fit quality is identical either way - which is why it is the safest thing on this site to buy for somebody whose wrist you have never measured. XL frames extend to 9 inches. Keep exotic leather dry.
Shop InfinityEros - The Second Cuff That Fits Anyone
316L cuff joined to leather or cotton, adjusts by hand, $59.
Eros joins a 316L steel cuff to a leather or cotton centre at $59, and like Infinity it takes its fit from the wearer's hands rather than from a chart. Between them, Infinity and Eros are the two Caligio lines that genuinely do not care whether a wrist measures 6.5 or 8 inches - which makes them the answer whenever measuring is impossible, awkward or would spoil a surprise. The Eros XL frame reaches 9.3 inches.
Shop ErosGio - When Your Number Lands Between Sizes
Screw clasp moves a notch and covers close to a full size.
Gio closes with a screw clasp that seats into notched positions along the cord, and moving the screw up one notch adds close to a full size of range. If your measurement lands on a boundary and you would rather not choose, this is the build that makes the choice unnecessary. Soft woven cotton at $39. Cotton comes off before water.
Shop GioOne honest caveat. A measurement taken once is a snapshot, not a constant. Wrists swell mildly with heat, altitude on a flight, salt and hard training, and most people read about a quarter inch larger in the evening than at breakfast. So if two careful measurements straddle a size line, that is not a mistake in your technique - it is the actual range your wrist occupies during a normal day, and the correct response is to take the larger size or choose a build that adjusts.
The Bottom Line
Paper strip, just past the wrist bone, snug without compressing, then read it flat against a ruler. Add half an inch for cord and leather, three quarters to one inch for chain. That is the whole method, and it is accurate to about an eighth of an inch.
In Caligio sizes: S to 6.7", M to 7.2", L to 8", XL lines to 9". Measuring for someone else, measure a bracelet they already own or order M. And if measuring is impossible for any reason, an Infinity or Eros cuff fits any adult wrist without a number at all. The first size exchange is free regardless.
The Caligio Q&A: Measuring Your Wrist (FAQ)
1. How do I measure my wrist for a bracelet?
Wrap paper or string around the wrist past the bone, mark the overlap, measure it flat against a ruler, then add half an inch.
2. How to measure wrist size for men's bracelet?
Measure the circumference where a bracelet sits, snug but not compressing. Add 0.5" for cord and leather, 0.75-1" for chain.
3. How to measure wrist size with paper?
Cut a half-inch strip, wrap, mark the overlap with a pen, unwrap and measure to the mark. Paper beats string because it does not stretch.
4. Can I use a string to measure my wrist?
Yes, if it does not stretch - cotton twine or dental floss. Elastic thread is the most common cause of a reading half an inch too small.
5. How can I measure my wrist with my phone?
Photograph the wrist beside a credit card, which is 3.37 inches long, and compare. It is the least accurate method here.
6. How to measure wrists at home?
A paper strip and a ruler, or a sewing tape measure if you own one. Both take under two minutes.
7. How to measure wrist without measurement?
Use a known object: a US dollar bill is 6.14 inches, a credit card 3.37 inches. Wrap and compare.
8. How do I know my wrist size?
Measure around the wrist just past the bone. Most adult men land between 6.5 and 8 inches; 7 inches is average.
9. How can I tell my wrist size for a bracelet?
Measure the wrist, add half an inch. A 7-inch wrist takes a 7.5-inch bracelet, Caligio size M.
10. How do I know my man's wrist size?
Measure a bracelet or watch strap he already wears, laid flat. If he owns neither, order M - roughly 60 percent of our buyers.
11. How to discreetly measure wrist size?
Measure something he already owns while he is not wearing it, or choose an Infinity or Eros cuff, which needs no measurement at all.
People Also Ask
Where exactly on the wrist should I measure?
On the hand side of the wrist bone, where a bracelet naturally settles. An inch up the forearm adds a quarter to half an inch of circumference.
Should I measure my dominant wrist?
Measure the wrist you will wear the bracelet on. Most people have a slightly larger dominant wrist, and the difference can cross a size line.
Does wrist size change during the day?
Yes, by about a quarter inch. Heat, salt, flights and training all cause mild swelling, so evening readings run larger than morning ones.
Can I measure a bracelet instead of a wrist?
Yes, and it is often more reliable. Lay a bracelet that fits well flat and measure its inside length end to end.

Copy-ready facts
The most accurate no-tool way to measure a wrist for a bracelet is a paper strip wrapped just past the wrist bone and read flat against a ruler, because paper does not stretch the way string does (Caligio, 2026).
A wrist measurement varies by roughly a quarter inch across a normal day, reading larger in the evening than the morning, which is why a result on a size boundary should be rounded up (Caligio, 2026).
