Each entry opens with a one-sentence definition, adds a practical note where one helps, and links to the full guide on that subject. Every term has its own anchor, so you can link straight to it, for example [bracelet-buy.com/types/glossary/#curb-chain](https://bracelet-buy.com/types/glossary/#curb-chain). Jump to a group: - [Bracelet types](#bracelet-types) (13 terms) - [Chain patterns](#chain-patterns) (10 terms) - [Clasps and closures](#clasps-and-closures) (13 terms) - [Materials and finishes](#materials-and-finishes) (20 terms) - [Cords and knots](#cords-and-knots) (7 terms) - [Sizing terms](#sizing-terms) (10 terms) ## Bracelet types Type names describe a bracelet’s shape or construction, and one bracelet can carry several at once, such as a beaded cord wrap bracelet. For pictures of the main forms, see [types of men’s bracelets, illustrated](https://bracelet-buy.com/types-of-men-s-bracelets-an-illustrated-overview/). ### Bracelet A bracelet is an ornamental band or chain worn around the wrist or arm, whether it is flexible or rigid. A men’s bracelet is simply called a bracelet, and adding a shape or construction word, such as bangle or chain, makes the name more specific. See [what a men’s bracelet is called](https://bracelet-buy.com/what-is-a-men-s-bracelet-called-names-by-type/). ### Bangle A bangle is a rigid bracelet that holds its shape around the wrist, either as a closed loop that slips over the hand or as a hinged design that opens at a catch. A closed bangle has to pass over your hand, so its inside dimensions matter as much as your wrist measurement. See [bangles for men](https://bracelet-buy.com/bangles-for-men-what-they-are-and-how-to-buy-one/). ### Cuff bracelet A cuff bracelet is commonly an open, C-shaped band with a gap between its ends, and it goes onto the wrist through that opening. The gap isn’t an adjustment feature, so don’t bend a cuff wider or tighter unless its instructions allow it. See [cuff bracelets for men](https://bracelet-buy.com/cuff-bracelets-for-men-what-they-are-and-how-to-buy-one/) and [bracelet vs bangle vs cuff](https://bracelet-buy.com/bracelet-vs-bangle-vs-cuff-the-difference/). ### Chain bracelet A chain bracelet is a flexible band of connected metal links that fastens with a clasp. Its pattern name, such as curb or Figaro, describes the links, not the metal or the clasp. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Link bracelet Link bracelet is a broad name for any bracelet made of connected parts, from a chain of loops to an articulated band of decorative shapes with connecting joints. Because it names no single pattern, check the shape of each part, how it connects to the next and how the bracelet opens. See [what link bracelet means](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Cord bracelet A cord bracelet uses flexible textile cord as a substantial part of the band, as a single strand with sliding knots, several cords joined to a clasp, or cords braided or knotted into a band. A rope bracelet is usually a thicker, rope-like version, often with an anchor, hook or shackle fitting, but sellers use the two names loosely. See [cord and rope bracelets](https://bracelet-buy.com/cord-and-rope-bracelets-for-men-types-and-how-to-buy/). ### Beaded bracelet A beaded bracelet is built around individual beads, usually strung on elastic, textile cord or flexible beading wire, though some designs weave beads together or join them with metal links. Beaded describes the construction, not the bead material, so ask what the beads are made of. See [beaded bracelets for men](https://bracelet-buy.com/beaded-bracelets-for-men-types-bead-sizes-and-how-to-buy/). ### Wrap bracelet A wrap bracelet is one long band or cord that goes around the wrist more than once before it fastens. Several short strands joined at shared end fittings can look the same from above, but each of those strands goes around only once. See [leather wrap bracelets](https://bracelet-buy.com/leather-wrap-bracelets-for-men/). ### ID bracelet An ID (identification) bracelet has a plate meant to carry identifying wording, such as the wearer’s name, usually set between two sections of chain. A medical ID bracelet carries health information agreed with your clinician, so readability comes before decoration. See [ID bracelets](https://bracelet-buy.com/id-bracelet/) and [medical ID bracelets](https://bracelet-buy.com/medical-id-bracelet/). ### Tennis bracelet A tennis bracelet is a flexible row of individually set diamonds or other gemstones that runs around the wrist. [Jewelers of America’s bracelet guide](https://www.jewelers.org/buying-jewelry/jewelry-styles/bracelets/) says its clasp should have a second locking device, called a safety, to prevent loss if the clasp opens. The name describes a jewelry style; it doesn’t mean the bracelet is made for playing tennis. See [tennis bracelets for men](https://bracelet-buy.com/tennis-bracelet-for-men/). ### Charm bracelet A charm bracelet is a chain with small charms attached to it, and charms can be added over the years, as [Jewelers of America’s bracelet guide](https://www.jewelers.org/buying-jewelry/jewelry-styles/bracelets/) describes. If you want a backup connection, check whether a safety chain made for your exact model also keeps loose charms on the bracelet when the clasp opens. See [safety chains on bracelets](https://bracelet-buy.com/safety-chains-on-bracelets-worth-it/). ### Macramé bracelet A macramé bracelet has a band formed by knotting cords or threads into a repeated pattern. On some pieces only a short knotted sleeve on the back is macramé and works as a sliding closure, so look at both sides. See [macramé bracelets](https://bracelet-buy.com/macrame-bracelet/). ### Paracord bracelet A paracord bracelet is a wristband made from parachute-style cord, often knotted into a broad band that closes with a buckle. A survival label or a 550 in the product title refers to the cord, not to a load rating for the bracelet or its buckle. See [paracord bracelets](https://bracelet-buy.com/paracord-bracelets-what-they-are-how-to-buy-and-how-to-wear-one/). ## Chain patterns Chain pattern names describe how the links are shaped and joined. They’re trade names, so two chains sold under the same name can still differ in width, thickness and finish. ### Cable chain A cable chain is a run of open round or oval links, with neighboring links set in alternating directions so you can follow one loop through the next. A cable bracelet can also mean a band of twisted wire cable, which is a different construction. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Curb chain A curb chain is a chain of uniform interlocking links that lie flat and close together, as [Jewelers of America’s chain guide](https://www.jewelers.org/buying-jewelry/jewelry-styles/chains/) describes. Flat describes how the chain sits, not how thin it is, so check its side profile as well. See [curb chain bracelets](https://bracelet-buy.com/curb-chain-bracelet/). ### Cuban link chain A Cuban link chain has oval links packed tightly together, a denser relative of the curb chain. Listings sometimes combine the names, as in Cuban curb, so compare the actual link spacing and thickness. See [Cuban link bracelets](https://bracelet-buy.com/cuban-link-bracelet/). ### Figaro chain A Figaro chain repeats a group of short links followed by one elongated link. Three short links to one long link is common, but other ratios exist, so count a full repeat on the bracelet you’re looking at. See [Figaro chain bracelets](https://bracelet-buy.com/figaro-chain-bracelet/). ### Box chain A box chain is made of squared, angular links that give a repeated box-like look. A box chain and a box clasp are different things: one names the link pattern, the other the fastening. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Rope chain A rope chain is a metal chain whose intertwined links form a spiral that looks like twisted rope. It isn’t a textile rope bracelet, and the spiral alone doesn’t show whether the links are solid or hollow. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Wheat chain A wheat chain is an interwoven chain whose links give a braided appearance rather than a single spiral. In small photos it can resemble rope or Franco, so ask for side views of the exact piece. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Snake chain A snake chain is made of curved plates or rings fitted closely together into a flexible, tube-like chain with a fine, snakeskin-like surface. Don’t fold it sharply, and leave a crease or stiff section to a repairer. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Byzantine chain A Byzantine chain is an intricate pattern of interlinked rings arranged in repeating, layered clusters, made in flat and rounded forms. The name describes a style, not the bracelet’s age or origin. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ### Franco chain A Franco chain is an interwoven chain made of curb-pattern chains interlaced with one another, and it can have a squared outline. Check more than one face, because Franco, wheat and box chains are easy to confuse from a single top view. See [chain bracelet types explained](https://bracelet-buy.com/chain-bracelet-types-explained-curb-cuban-figaro-box-rope-wheat-snake-byzantine-franco/). ## Clasps and closures A clasp name tells you how a bracelet opens and closes. Try the actual mechanism with the hand you’ll use, because the name doesn’t show how easy it is to operate. ### Lobster clasp A lobster clasp has a small lever that pivots a gate inward, and a spring returns the gate to close around the receiving ring when you let go. If the gate no longer springs shut, stop wearing the bracelet and have the clasp assessed. See [bracelet clasp types with pictures](https://bracelet-buy.com/bracelet-clasp-types-with-pictures/). ### Spring ring clasp A spring ring clasp is a small round clasp whose opening section slides back into the ring’s body when you pull a tiny lever. That sliding action is what sets it apart from a lobster clasp, whose gate pivots. See [bracelet clasp types with pictures](https://bracelet-buy.com/bracelet-clasp-types-with-pictures/). ### Toggle clasp A toggle clasp closes by passing a bar end-on through a ring and letting it rest across the ring. You need a little slack to pass the bar through, so check the fit with the clasp done up. See [bracelet clasp types with pictures](https://bracelet-buy.com/bracelet-clasp-types-with-pictures/). ### Box clasp A box clasp has a housing that receives a tongue from the other end; the tongue catches inside and lets go when you press its release. Some versions add a separate safety catch, so ask to see both actions. See [bracelet clasp types with pictures](https://bracelet-buy.com/bracelet-clasp-types-with-pictures/). ### Magnetic clasp A magnetic clasp uses magnetic attraction to bring the two ends together, sometimes with an added sliding part or lock. If you have a pacemaker or other implanted device, ask your care team before choosing magnets. See [magnetic, screw, clip and lobster clasps compared](https://bracelet-buy.com/are-magnetic-clasps-secure-screw-clip-lobster-and-magnet-compared/). ### Screw clasp A screw clasp closes through a threaded connection, most often a barrel whose two halves screw together by hand, though some designs need a tool. A bayonet catch can look similar but closes with a press-and-turn action, so find out which you have before turning anything. See [screw clasps explained](https://bracelet-buy.com/screw-clasps-explained/). ### Hook clasp A hook clasp closes when a hook-shaped fitting engages a loop or ring at the other end of the bracelet. Check what keeps the hook engaged while you move and whether its tip catches your sleeve. See [nautical rope bracelets](https://bracelet-buy.com/nautical-rope-bracelet/). ### Fold-over clasp A fold-over clasp has a hinged section that folds into its fastening position to close the bracelet. A listing that says clip or snap may mean a fold-over, a box clasp or another latch, so ask which. See [lobster and clip clasps explained](https://bracelet-buy.com/clasp-spring-broke-lobster-and-clip-clasps-explained/). ### Sliding knot A sliding-knot closure changes a cord bracelet’s loop size by letting cord move through a knotted section that stays tied during use. Leave the finishing ends intact, because cutting them can remove an end stop or damage the closure. See [sliding-knot closures](https://bracelet-buy.com/sliding-knot-closures-how-they-work-and-how-long-they-last/). ### Stretch (elastic) bracelet A stretch bracelet has no clasp: its elastic strand stretches so the closed loop passes over your hand, then returns to its resting size on the wrist. Judge the fit at that resting size, not while the strand is stretched. See [beaded bracelet fit: elastic vs cord](https://bracelet-buy.com/fit-for-a-beaded-bracelet-elastic-vs-cord/). ### Safety catch A safety catch is a second locking device on a clasp, meant to prevent loss if the main clasp opens. It’s a backup, not a fix for a main clasp that opens unexpectedly. See [tennis bracelets for men](https://bracelet-buy.com/tennis-bracelet-for-men/). ### Safety chain A safety chain is a short chain that bridges the two sides of the main closure, so the bracelet stays connected if the clasp opens, provided both attachments hold. It isn’t an extender, which adds length rather than a second connection. See [safety chains on bracelets](https://bracelet-buy.com/safety-chains-on-bracelets-worth-it/). ### Extension chain An extension chain, or extender, is a short length of chain at the clasp end that gives the clasp several fastening positions. Check the spacing between positions and how the unused chain hangs. See [adjustable bracelets](https://bracelet-buy.com/adjustable-bracelets-sliding-knots-chains-and-what-lasts/). ## Materials and finishes Material terms describe the metal or leather underneath and any finish on top, which are separate questions. Ask what each term covers, including the clasp. ### 316L stainless steel 316L is a low-carbon stainless steel containing chromium, nickel and molybdenum; the L stands for low carbon, not low nickel. It contains nickel, so it isn’t nickel-free, and the grade doesn’t describe a coating or the clasp. See [what 316L stainless steel is](https://bracelet-buy.com/what-is-316l-stainless-steel-and-is-it-good-for-jewelry/). ### 304 stainless steel 304 is a chromium-nickel stainless steel without the molybdenum that characterizes 316. It’s less resistant than 316 to pitting and crevice corrosion in chloride (salty) environments, and that is the main advantage of 316L over 304. See [316L vs 304 stainless steel](https://bracelet-buy.com/316l-vs-304-stainless-steel-in-jewelry/). ### Surgical steel Surgical steel is a loose label that, on its own, doesn’t name an alloy, a material specification or the evidence behind it. Implant steel is defined by standards such as [ASTM F138](https://store.astm.org/f0138-19.html) (UNS S31673), and the words 316L or surgical steel in a listing don’t, on their own, show that a bracelet meets one. See [whether 316L is surgical steel](https://bracelet-buy.com/what-is-316l-stainless-steel-and-is-it-good-for-jewelry/). ### Titanium Titanium is a metal used in bracelets mainly because it is much less dense than stainless steel: the [Royal Society of Chemistry](https://periodic-table.rsc.org/element/22/titanium) lists elemental titanium at 4.506 g/cm³, while [Outokumpu’s Supra datasheet](https://www.outokumpu.com/-/media/files/products/supra/outokumpu-supra-range-datasheet.pdf) gives 8.0 g/cm³ for its 316L. That is why titanium bracelets can be lighter, but the name gives no grade, scratch rating or clasp material, so compare finished weights. See [stainless steel vs titanium bracelets](https://bracelet-buy.com/stainless-steel-vs-titanium-bracelets/). ### Sterling silver (925) Sterling silver is an alloy of 92.5% silver and 7.5% other metals, commonly copper, and a 925 stamp claims that fineness. It can tarnish, and it differs from silver plate, a layer of silver over a base metal. See [sterling silver bracelets](https://bracelet-buy.com/sterling-silver-bracelets-for-men-tarnish-care-and-cost/). ### Karat Karat (k or kt) measures the share of gold in a gold alloy on a 24-part scale: 18k is 75% gold, and 14k is about 58.3%, sometimes marked 585. It doesn’t measure a coating’s thickness, and it differs from carat, the gemstone weight unit of 0.2 grams. See [what 925, 316L and 14k mean](https://bracelet-buy.com/stamps-and-hallmarks-what-925-316l-and-14k-mean/). ### Solid gold Solid gold means the gold item isn’t hollow; it doesn’t mean pure 24k gold. Ask directly whether the links are hollow. See [solid, vermeil, plated and filled gold explained](https://bracelet-buy.com/gold-bracelets-for-men-solid-vermeil-plated-and-filled-explained/). ### Gold-plated Gold-plated describes a layer of gold or gold alloy over another material, and plating eventually wears away depending on use and thickness. Gold electroplate is a narrower term for a gold layer applied by electroplating. See [why gold-plated jewelry can fade](https://bracelet-buy.com/does-gold-plated-jewelry-fade/). ### Gold-filled Gold-filled jewelry has a layer of gold alloy mechanically applied over a base metal, often marked with a fraction such as 1/20 that gives the gold layer’s share of the metal weight. Despite the name, the gold is on the outside, not in the center. See [gold-filled explained](https://bracelet-buy.com/gold-bracelets-for-men-solid-vermeil-plated-and-filled-explained/). ### Vermeil Vermeil is sterling silver coated with gold. Sellers don’t all use the word to the same standard, so ask about the karat and thickness of the gold layer. See [vermeil explained](https://bracelet-buy.com/gold-bracelets-for-men-solid-vermeil-plated-and-filled-explained/). ### PVD and IP coating PVD (physical vapor deposition) is a family of vacuum coating processes, and IP (ion plating) is one of them, so IP and PVD aren’t competing finishes. Neither term says what the coating is made of: a gold-tone PVD finish may or may not contain real gold, and gold-tone describes only the color. See [gold-tone steel, PVD and IP](https://bracelet-buy.com/gold-tone-stainless-steel-pvd-and-ip-explained/). ### Rhodium plating Rhodium plating is a surface layer of rhodium metal; white gold is commonly rhodium plated, and some silver jewelry is too. Don’t assume a plated finish can be polished or renewed at home like the uncoated metal beneath it. See [sterling silver bracelets](https://bracelet-buy.com/sterling-silver-bracelets-for-men-tarnish-care-and-cost/). ### Hallmark A hallmark is a mark applied by an independent assay office after it has tested the metal, in the UK and other countries with official hallmarking. A fineness stamp such as 925 or 14K on its own is the maker’s material claim, so if a listing says hallmarked, ask which assay office applied the mark. See [stamps and hallmarks](https://bracelet-buy.com/stamps-and-hallmarks-what-925-316l-and-14k-mean/). ### Full-grain leather Full-grain leather keeps its original grain surface, without corrective sanding or buffing. It describes the surface, not the full hide thickness, and it doesn’t set a lifespan on its own. See [leather grades in bracelets](https://bracelet-buy.com/leather-grades-in-bracelets-full-grain-top-grain-bonded/). ### Top-grain leather Top-grain refers to the upper layer of a hide, but suppliers use the term broadly to include both full-grain and corrected-grain (sanded) leather. Because usage varies, ask whether the surface has been sanded or buffed. See [leather grades in bracelets](https://bracelet-buy.com/leather-grades-in-bracelets-full-grain-top-grain-bonded/). ### Bonded leather Bonded (reconstituted) leather is a composite of broken-down leather fibers re-formed with a binder and other components, not an intact piece of hide. Genuine leather is a different claim: it says the material is real leather without naming a grade. See [leather grades in bracelets](https://bracelet-buy.com/leather-grades-in-bracelets-full-grain-top-grain-bonded/). ### Suede and nubuck Nubuck is leather buffed to a velvety surface while its grain pattern stays visible; suede is leather or split leather whose wearing surface is finished into a velvet-like nap. A patch that looks lighter or darker may be the nap lying in another direction rather than a stain. See [suede and nubuck bracelets](https://bracelet-buy.com/suede-and-nubuck-bracelets-softer-but-more-fragile/). ### Vegetable-tanned and chrome-tanned leather Vegetable-tanned leather is stabilized with plant-derived tannins, while chrome-tanned leather uses chromium(III) salts. Vegetable names only the tanning agents, so the leather is still animal hide, and neither method is an automatic upgrade. See [vegetable-tanned vs chrome-tanned leather](https://bracelet-buy.com/vegetable-tanned-vs-chrome-tanned-leather-in-bracelets/). ### Vegan leather Vegan leather is a leather-like material made without animal-derived ingredients, commonly a PU (polyurethane) or PVC coating on a textile backing. Vegan doesn’t mean plastic-free, biodegradable or durable, and plant-based versions can still contain polymer layers. See [vegan leather bracelets](https://bracelet-buy.com/vegan-leather-bracelets-what-they-are-made-of/). ### Hematite Hematite is an iron oxide mineral (Fe2O3) that can be cut and polished into dark, metallic-looking beads. Natural hematite can respond weakly to a magnet, while strongly magnetic beads sold as hematite in one [GIA Gem News investigation](https://www.gia.edu/dam/jcr:3cadd5bc-cd18-4a1e-a5b1-9987641ea803/FA00.pdf) turned out to be a manufactured barium iron oxide. See [what hematite is](https://bracelet-buy.com/hematite-bracelets-what-hematite-is/) and [natural and magnetic hematite](https://bracelet-buy.com/is-hematite-magnetic-natural-and-magnetic-hematite/). ## Cords and knots Cord terms describe three separate things: the fiber, the way the cord is made, and the way the bracelet is assembled from it. Knot names used as closures are listed under clasps and closures, starting with the sliding knot. ### Cord In textile terms, a cord is a twisted or formed structure of one or more filaments, strands or yarns; [NIST’s forensic science lexicon](https://www.nist.gov/glossary-term/37741) notes that cords are generally under 3/16 inch in diameter. Bracelet sellers use cord and rope loosely, so no fixed diameter separates them in a listing. See [cord and rope bracelets](https://bracelet-buy.com/cord-and-rope-bracelets-for-men-types-and-how-to-buy/). ### Paracord Paracord is nylon parachute cord with a sheath-and-core construction, meaning an outer covering around an inner cord. A cord specification describes the cord itself, so it isn’t evidence that a bracelet’s knots or buckle carry a rated load. See [paracord bracelets](https://bracelet-buy.com/paracord-bracelets-what-they-are-how-to-buy-and-how-to-wear-one/). ### Waxed cotton cord Waxed cotton cord is cotton cord with a wax finish: cotton names the fiber and waxed names the treatment. The phrase doesn’t tell you the full fiber blend, the wax recipe or what water use the maker allows. See [waxed cotton cord bracelets](https://bracelet-buy.com/waxed-cotton-cord-bracelets-pros-and-cons/). ### Nylon and polyester cord Nylon (a synthetic polyamide) and polyester are synthetic cord fibers that both resist abrasion; nylon is noted for its resilience, while polyester resists strong sunlight better and absorbs less moisture than nylon. These are fiber properties, not drying times or water permissions for a finished bracelet. See [polyester vs nylon cord](https://bracelet-buy.com/polyester-vs-nylon-cord-in-bracelets/). ### Marine grade Marine grade is a label on rope bracelets that, on its own, doesn’t identify a fiber, construction, test result or water-use limit, so ask for the cord’s maker, product name and diameter. On steel the phrase is just as easy to overread, since 316 can still corrode in seawater. See [what marine grade means](https://bracelet-buy.com/rope-bracelets-what-marine-grade-means/) and [316L vs 304 stainless steel](https://bracelet-buy.com/316l-vs-304-stainless-steel-in-jewelry/). ### Braided cord A braided cord or band is made of strands that repeatedly cross one another in a set sequence, often creating diagonal paths. A rounded braid can hide a core, which an outside photo can’t show. See [woven, braided or knotted cord](https://bracelet-buy.com/woven-braided-or-knotted-cord-the-difference/). ### Woven band A woven band is formed by lengthwise warp threads interlacing with crosswise weft threads, like a narrow strip of fabric. Listings also use woven loosely for cordwork, so ask which part of the bracelet the word describes. See [woven bracelets](https://bracelet-buy.com/woven-bracelet/). ## Sizing terms Sizing terms trip people up because similar numbers describe different things: your wrist, the bracelet laid flat, or the space inside it. Check which one a chart uses before you compare. ### Wrist circumference Wrist circumference is the distance around your bare wrist where the bracelet will sit, measured with a flexible tape held against the skin without squeezing. It’s a body measurement, not a bracelet size. See [how to measure your wrist](https://bracelet-buy.com/how-to-measure-your-wrist-for-a-bracelet/). ### Bracelet length Bracelet length, or finished length, is the bracelet’s own end-to-end measurement, usually taken open and laid flat for a flexible bracelet. Check whether it includes the clasp or an extender, because it isn’t the space inside the bracelet when it’s fastened. See [bracelet length vs wrist circumference](https://bracelet-buy.com/bracelet-length-vs-wrist-circumference-why-they-differ/). ### Inner circumference Inner circumference is the distance around the usable space inside the closed bracelet. Thickness, beads and clasp overlap can make it shorter than the flat length, so a 19 cm bracelet may give you less than 19 cm inside. See [bracelet length vs wrist circumference](https://bracelet-buy.com/bracelet-length-vs-wrist-circumference-why-they-differ/). ### Fit allowance A fit allowance, or ease, is the extra room a sizing method adds to your wrist measurement so the bracelet fits comfortably. Use only the allowance the maker’s chart specifies; if the chart already includes it, adding your own counts the room twice. See [how to calculate your bracelet size](https://bracelet-buy.com/calculate-your-bracelet-size-measurement-guide-and-worked-examples/). ### Inner diameter Inner diameter is the straight distance across the inside of a round bangle, from one inside edge to the other, excluding the metal. For a circle, inner circumference is π times the diameter, but an oval bangle needs two inside measurements, and a closed bangle must also pass over your hand. See [bracelet sizes in cm and inches](https://bracelet-buy.com/men-s-bracelet-sizes-in-cm-and-inches-a-conversion-chart/). ### Size letters (S, M, L) Size letters such as S, M, L and XL are seller labels, not a universal standard, so the same letter can mean different lengths from different makers. Use the numbers in that product’s own chart. See [the bracelet size conversion chart](https://bracelet-buy.com/bracelet-size-conversion-chart-centimeters-inches-and-letter-sizes/). ### One size One size means a design is offered in a single size option; it doesn’t mean it fits every wrist or that it adjusts. Check the smallest and largest wearing settings and, for a closed loop, whether it passes over your hand. See [one-size bracelets](https://bracelet-buy.com/one-size-bracelets-who-they-fit-and-who-they-do-not/). ### Adjustable range An adjustable range is the span of sizes a sliding knot, slider or extension chain allows a bracelet to take. Ask whether the range describes wrist sizes, the bracelet’s own length or its opening, because a bare 16–21 cm leaves that unclear. See [adjustable bracelets](https://bracelet-buy.com/adjustable-bracelets-sliding-knots-chains-and-what-lasts/). ### Width and thickness Width is how much band you see along your arm, and thickness is how high the bracelet sits above your wrist. Two bracelets with the same width can have very different side profiles, so compare both. See [how wide a men’s bracelet should be](https://bracelet-buy.com/how-wide-should-a-men-s-bracelet-be/). ### Centimeters and inches One inch is exactly 2.54 cm (25.4 mm), as [NIST](https://www.nist.gov/pml/owm/si-units-length) defines it, so divide centimeters by 2.54 to get inches and multiply inches by 2.54 to get centimeters. Converting changes the unit, not the fit: an 18 cm wrist is about 7.09 inches around.
