How to Measure Your Wrist for a Leather Bracelet That Fits
"I'm a size M in everything, so an 18cm total length bracelet will fit me fine."
Nope.
How to Measure Your Wrist for a Leather Bracelet
Use a flexible measuring tape or a piece of string. Wrap it around your bare wrist exactly where you want the bracelet to sit. Keep it comfortably flush against your skin without adding extra room. Record the measurement and send that exact number to your maker.
"But I can I just use my usual bracelet size."
Nope, you can't.
"But I know the measurements of this chain here and,-"
Nope. It won't fit.
This is the single biggest misconception in handmade jewelry.
People treat wrist sizes like shoe sizes, assuming a "17cm wrist" translates into a universal, off-the-rack bracelet length across every brand on the planet.
Then the package arrives. One bracelet cuts off circulation like a tourniquet, while another from a different shop slides down to their elbow.
So what gives? Why is sizing handcrafted leather so deceptively tricky? Let me share the quirks of inner-circumference geometry first, and you'll understand why your "usual size" is lying to you.
The Physics of Thickness (Outer vs. Inner Circumference)
Here is a math secret that catches almost everyone off guard: A 20cm long flat strip of leather does NOT give you a 20cm hole when you curl it into a circle.
This Eagle Cuff is made of thick black oiled vachetta leather (2.8mm thickness). It also has two snap buttons for adjusting. My wrist is 17cm. The bracelet's flat total length is 21cm!
4cm - that's over 1 inch - added just for the bracelet to circle a M size wrist, and close properly.
Who knew?
When you bend thick leather into a loop, the outside edge has to stretch, while the inside edge compresses.
This is a skinny band (1.2mm thickness), just 1cm / 0.4" wide. My wrist is 17cm and the closure is a single stud button. Putting the band down against the ruler, and the button-hole distance is exact 17.5cm for this snug (but comfortable) fit.
The specific leather is soft and because of the band's minimal thickness and width, it has more elasticity to fit comfortably at the (almost) exact wrist's circumference.
Because...
A thin 1.5mm leather cord curled into a circle loses almost no interior space.
A chunky 3mm cuff takes up a big amount of internal volume just by curving around itself.
If I make a thin cord bracelet at 18cm total length and a heavy 3mm thick cuff at 18cm total length, the heavy cuff will not fit your wrist.
Same total length, completely different fit!
Cuff Width & Hardware Geometry
It’s not just about thickness, but width matters just as much.
A sleek 1cm wide leather band wraps smoothly over your wrist bone - and I personally love wearing my bracelets below my wrist bone.
A bold 4cm wide cuff covers a much bigger piece of real estate, covering your wrist bone, riding higher up your forearm where your arm naturally widens.
Add closure hardware into the mix like buckles that require a part of the bracelet to fold, magnetic clasps, or overlapping snaps and maybe double closures for adjusting,
—and the geometry changes again. Some clasps add an extra centimeter of flat bridge, while overlapping snaps steal length from the interior loop.
Wrist Anatomy & Gender Structure
Two people can both measure a 17cm wrist circumference, but their wrists might look completely different in cross-section:
Flat & Wide: Common in many male wrist structures, requiring a slightly different clearance to prevent the leather from pinching on the sides.
Round & Prominent Bone: Common in female wrist structures, where a bracelet has to gracefully bridge the ulna (that round wrist bone) without catching or twisting awkwardly.
Genders aside, both wrist constructions exist.
Causing a different fit.
Meaning each one needs a different approach to get the correct fit.
Depending on a gazillion of other factors.
Where you like to wear your bracelet also plays a role
Do you like it snug above the bone, loose enough to dangle near your palm, or stacked alongside a heavy watch or multiple stacks? And in which position?
I want my bracelets closer to my palm. I don't like anything rubbing against my wrist bone. Many people (if not most) like their bracelets to sit right above their wrist bone.
And others stack them higher, because they already wear a watch, an old bracelet their best friend gave them and they never take it off, and also like to mix & match with elastic cord beaded bracelets, having a nice stack of multiple things around their wrist.
And everyone needs a different size, even if their wrist measure the same 🫠
Why I Beg for Your Exact Bare Wrist Measurement
I don't want you to measure your favorite old bracelet, and I don't want you to assume the size you should order based on -whatever might looks logical.
My Size Chart refers to your wrist's measurements and not the bracelet's measurements.
When you give me your exact, skin-tight wrist circumference, I do all the hidden math for you. I take your raw measurement and add specific clearance based on:
The exact thickness of that specific hide,
The width of the strap,
The bulk of the clasp,
Whether it’s an adjustable wrap or a fixed cuff,
Where the clasp sits on the underside of your wrist so it doesn't hit your bones,
The flexibility and elasticity of the leather,
And
and
and...
And if there's anything else I need to know, please share! Your secrets are safe with me.
Throw out the idea of being a universal "M Size."
Grab a flexible tailor's tape (or a piece of string and a ruler), wrap it flush against your skin right where you want the bracelet to sit, and give that exact number to your maker.
Let us handle the leather physics; we promise your wrist will thank you!
