How to Measure Your Wrist for a Bracelet

Use a flexible measuring tape and measure the exact wrist where the bracelet will normally sit. Keep the tape close to the skin without pulling it tightly enough to compress the wrist. Record the measurement in centimetres or millimetres. That number is your wrist circumference.

If you do not have a flexible tape, wrap a non-stretch strip of paper or string around the wrist, mark where the ends meet, lay it flat and measure the marked length with a ruler. Then identify the bracelet type. For a flexible chain, station or tennis bracelet, the bracelet normally needs some ease beyond the body circumference. For a closed slip-on bangle, wrist circumference alone may be insufficient because the rigid circle also needs to pass over the hand. For a hinged bangle, the opening mechanism means sizing can be based more directly on wrist fit. For a cuff, use the maker's actual wrist-size guidance and internal dimensions where supplied.

Imagine your wrist measures exactly 16 cm. That tells you that the circumference of your wrist at the measuring point is 16 cm. It does not automatically mean that every 16 cm bracelet will fit properly. A flexible bracelet that closes at exactly 16 cm may sit extremely close to the skin. A 17 cm flexible bracelet would provide approximately 1 cm of additional circumference. Whether either amount is correct depends on the bracelet design and the fit you want.

Measure the point where the bracelet will actually sit. This becomes particularly important if you wear your bracelets above the wrist bone, close to the hand or as part of a stack. Your forearm gradually changes circumference as you move away from the wrist. A measurement taken in one position may therefore be wrong for jewellery intended to sit somewhere else. If you are planning a stack, measure at the location where each bracelet is expected to rest.

Wrap a flexible tape measure around the wrist at the intended wearing position. Keep it flat against the skin. The tape should be snug enough to follow the actual circumference but should not dig into the wrist. Read the point where the tape meets itself. Record that number without adding any extra fit allowance yet. Keep the raw measurement. The additional room should be determined only after you know what type of bracelet you are choosing.

Use the unrounded centimetre or millimetre measurement whenever the product's sizing system is precise enough to support it. Do not round too early. Suppose the wrist measures 16.4 cm. Rounding it immediately to 16 cm removes 4 mm. Rounding it to 17 cm adds 6 mm. That difference can matter on a closely fitted bracelet.

This is where bracelet sizing separates into several different paths. A flexible bracelet follows the wrist. A bangle holds a rigid shape. A cuff is rigid but open. These designs should not share one universal sizing formula.

Flexible bracelets include many tennis, chain and station designs. Measure the bare wrist first. Then compare that circumference with the finished bracelet's actual wearable size. A flexible bracelet normally needs some room for movement, but the amount depends on the design. A tennis bracelet will generally be worn more closely than a deliberately loose chain bracelet. That means there should not be one site-wide rule such as: "Always add 2 cm."

These examples illustrate the mathematics. They are not universal fit recommendations. The correct choice depends on whether the product is a tennis bracelet, chain bracelet or another construction.

Start with your wrist circumference at the point where the tennis bracelet will sit. A tennis bracelet should normally have enough room for slight controlled movement without travelling excessively up and down the arm. Current GIA guidance uses the ability to place approximately one finger between the wrist and the bracelet as a practical reference for a classic tennis-bracelet fit. That does not mean you should convert "one finger" into one fixed centimetre allowance. Finger thickness differs between people. Use it as a final fit check rather than a mathematical sizing formula.

A retailer may publish a bracelet as 18 cm long. But what exactly has been measured? It could mean: the total end-to-end length laid flat, the length including part of the clasp, the nominal product size, or: the usable internal circumference when closed. Those are not automatically identical. For accurate online sizing, product pages should state how the length was measured. Aurelia should publish whichever measurement actually corresponds to the customer's fit decision and label it clearly.

A traditional closed bangle has no clasp or hinge. It must pass over the hand before reaching the wrist. That changes the measurement completely. Your wrist may measure only 16 cm, but the rigid bangle still has to clear the knuckles and widest section of the hand. For this type of bangle, wrist circumference alone is not enough. Measure the widest hand circumference that the rigid bangle must pass over.

Bring the thumb towards the palm as though you were about to slide on a bangle. Bring the fingers together naturally. Wrap the measuring tape around the widest group of knuckles and hand. Record that circumference. This measurement helps determine whether the rigid internal opening can physically pass over the hand.

Do not treat all products labelled bangle as mechanically identical. A hinged bangle opens, so sizing is based more on wrist fit and internal dimensions rather than hand clearance.

A cuff is generally rigid or semi-rigid and has an opening rather than forming a fully closed circle. Measure the wrist where the cuff will sit. Because cuffs vary significantly in shape and opening width, wrist circumference is only the starting point. The product's actual internal dimensions and size range matter. Do not assume the cuff can simply be bent wider or narrower. Repeated bending can damage some constructions or alter stone settings. Only adjust a cuff if the specific product is designed for adjustment.

These are measurement examples, not Aurelia product specifications.

Sometimes a particular brand or product may recommend that. It should not be treated as a universal jewellery rule. For example, Cartier's current general bracelet sizing tool recommends adding 1 cm for a loose fit within Cartier's sizing system. Other brands use different recommendations. This means the correct approach is: measure your bare wrist accurately first, then follow the sizing method for the actual bracelet you are buying. Do not alter the body measurement itself. Some bracelet systems and charm-bracelet guides use larger allowances because their constructions and intended contents require more room. Treat fixed centimetre additions as product-specific sizing instructions, not mathematical laws.

First identify how the retailer defines each size. If the product uses actual bracelet lengths, compare those lengths with your wrist measurement. If the product uses Small, Medium and Large, use the wrist ranges assigned by the manufacturer. If the piece is rigid, inspect the internal dimensions as well. Do not automatically choose the larger size unless the manufacturer's own sizing guidance recommends it. Bracelet size labels are not standardised — one brand's Medium does not necessarily equal another brand's Medium.

Your two wrists may not have identical circumferences. Measure the wrist on which the bracelet will actually be worn. Do not assume the measurement from the opposite wrist is interchangeable. This matters especially for close-fitting tennis bracelets, cuffs and bangles. If you wear several bracelets together, they may naturally sit at slightly different points on the arm. Measure those positions rather than assuming one wrist measurement works for the complete stack.

Yes, potentially. A broad rigid cuff covers more wrist surface than a very fine chain bracelet. Two bracelets with the same nominal internal size can therefore feel different. Width, finished weight, rigidity and movement all influence comfort. The numerical size is only part of the fit. Weight does not directly change wrist circumference, but it can change how the bracelet behaves. A heavier flexible bracelet may settle more noticeably around the wrist.

A 17 cm bracelet can fit a wrist perfectly and still have poor articulation or an inadequate clasp. Sizing and workmanship are separate decisions. Once you determine the correct dimensions, check: the clasp, stone settings, link movement, hinges, and overall construction.

If a customer enters their wrist measurement into Aurelia's waitlist, that should be treated as preference information unless a later order process confirms a specific bracelet size. Joining the waitlist should not mean: a bracelet has been ordered, a bespoke size has been accepted, the bracelet has been reserved, or production has started.

The key principle is simple: measure the body accurately first and interpret the jewellery second.

Measure the bare wrist first. Use a flexible measuring tape around the exact location where the bracelet will sit. Keep the tape snug against the skin without compressing it. Record the result accurately in centimetres or millimetres. Do not immediately add 1 cm, 1.5 cm or 2 cm.

Next identify the bracelet construction. For a tennis, chain or station bracelet, use wrist circumference as the starting point and then select the appropriate additional room according to the actual product's sizing system. For a closed slip-on bangle, also measure the widest part of the hand because the rigid bangle must physically pass over it. For a hinged bangle, use wrist circumference and the manufacturer's internal sizing because it opens around the wrist. For a cuff, measure the intended wearing position and follow the cuff's product-specific wrist range and internal dimensions.

Most importantly, keep these two numbers separate: Wrist circumference = your body measurement. Bracelet length = the jewellery measurement. They are related, but they are not interchangeable.
