Ring size: measuring your finger
In France, the ring size is a simple number: it is the finger circumference in millimeters. A finger with a circumference of 54 mm is a size 54. There is nothing else to calculate.
Here are the three ways to get it at home. The first is the most reliable if you don't have a ring on hand.
Method 1 · the strip of paper (the most reliable)
Cut a strip of paper about 6 mm wide and 10 cm long. Use ordinary paper, definitely not string or elastic: anything that stretches will distort the measurement.
Wrap it around the base of the relevant finger, flat, tight but without compressing the skin.
Mark the exact spot with a pen where the end meets the strip.
Unfold and measure from the edge to the mark, in millimeters. That is your size.
Repeat the measurement twice at a few minutes' interval. If you get 53 then 55, use 54.
Then check that the strip passes the knuckle, not just the base of the finger. On a prominent knuckle, it is the knuckle that counts: a ring that won't go over won't be worn.
Method 2 · measuring a ring you already wear
Take a ring worn on the same finger and the same hand (the dominant hand's finger is often wider). Place it on a ruler and measure its inner diameter, from one inner edge to the other, passing through the center.
Multiply this diameter by 3.1416 to get the circumference, which is the French size. An inner diameter of 16.6 mm gives 52.1, which means a size 52.
Be sure to measure the inner edge. On a thick ring, measuring the outer edge easily adds 3 to 4 mm, resulting in an error of more than a full size.
Method 3 · the printable ruler
This ruler is drawn to actual size. Print this page, then measure your strip of paper directly on it.
Before using it, check the scale: the golden frame must measure exactly 5.0 cm under a real ruler. If it is smaller, your printer has reduced the page. Print again with the scale set to 100% (and not "fit to page").
Table: finger circumference in millimeters and corresponding diameter
This table is purely geometric: the French size is the circumference, and the diameter is deduced by dividing by 3.1416. Use this if you have measured a diameter rather than a finger circumference.

Source: size options taken from our engagement and wedding rings, and our 925 sterling silver moissanite and diamond rings. Beyond 8 US, our product pages do not indicate a French equivalent: in that case, measure your finger circumference and rely on the table for the product.
Beware of letters S, M and L. On our rings, the letter does not have the same value from one model to another: depending on the collection, an M equals 8 US on some models and 9 US on others, and an XS is sometimes 6 US, sometimes 7 US. The letter is just a storage label. Always read the number that accompanies it in the size selector on the product page.
The pitfalls that cause sizing errors
Measuring in the morning. Fingers are thinner upon waking. Measure in the late afternoon, when the finger is at its usual volume.
Measuring in cold weather. Cold significantly shrinks finger size; heat, exercise, and salt cause it to swell. Hand should be warm and at rest.
Forgetting the knuckle. The ring must pass over the joint. If the knuckle is significantly wider than the base, take the larger of the two measurements.
Ignoring the width of the ring band. Above 8 mm wide, a ring fits tighter for the same size: allow for half a size up. This is the case with our signet rings and Cuban rings.
Measuring the wrong finger. The pinky, ring finger, and middle finger often differ by two to three sizes.
Two criteria count: the length, which determines the drop point on the chest, and the link width, which determines the presence of the jewelry. Our chains exist in 40, 45, 50, 55, 60, and 70 cm.

Lengths taken from our chains and necklaces. The drop points are indicative: they vary with build and neck morphology.
Measuring your neck size
If you are hesitating, measure: pass a flexible tape measure, or a strip of paper, around the base of the neck, without tightening. A neck size of about 38 cm paired with a 45 cm chain leaves the jewelry dropping just below the throat.
The conversion rule is simple: each centimeter added to the chain lowers the drop point by about half a centimeter on the chest, since the length is distributed on both sides of the neck.

Less than that, the chains will tangle
Choosing link width
The width is read in millimeters, and it determines the look of the jewelry much more than the length.
3 to 5 mm: discreet. The chain is worn alone or supports a small pendant.
8 to 12 mm: present. It becomes a visible element of the outfit.
14 mm and up: centerpiece. It dominates the silhouette and requires an appropriate build.
Widths taken from our chains and bracelets: 3, 4, 5, 8, 10, 12, 14, 15, 16, 18, and 20 mm depending on the model.
The wider the link, the more length needed for it to fall correctly. A 14 mm link in 45 cm gives a choked look: at this width, start from 55 cm.
A bracelet should not be chosen by the raw wrist circumference, but by wrist circumference plus comfort/ease. Without this margin, the bracelet will not close or will cut into the skin.
Measuring, in three steps
Measure just below the wrist bone, where the bracelet will actually sit, with a flexible tape measure or a strip of paper.
If using paper, mark the meeting point then transfer the length to a ruler.

Ease table: simple addition to your measurement, to be cross-referenced with the lengths available on the product page.
Lengths of our bracelets
Our bracelets are offered in 17, 18, 20, and 23 cm depending on the model. Compare your measurement (plus ease) to the closest length.
Same warning as for rings: the letter is not enough. Depending on the bracelet, an S equals 17 cm on some models and 18 cm on others, and an M most often equals 20 cm but goes down to 17 cm on a few references. Always rely on the number of centimeters displayed in the selector, never the letter alone.
Three useful habits
Between two sizes? Ask yourself how you like to wear it: tight, go smaller; relaxed, go bigger.
Wide link: aim for higher ease. A thick bracelet that is too tight climbs onto the bone and becomes uncomfortable in a few hours.
Upon receipt, a new bracelet is stiff and may be annoying during the first few days. The links soften quickly with use.
A watch is chosen based on two dimensions: the case diameter, which depends on the wrist width, and the bracelet length, which is adjusted by removing links. Our watches are delivered at a standard length and then adjusted to the wrist.

Removing links, step by step
1. Estimate how many links to remove
Place the bracelet on your wrist as you wish to wear it, then pinch the excess part as if it were already removed. The links that hang down tell you the number to remove.
It is much easier to remove an extra link than to reattach a missing one. Remove the same number of links from each side of the case so that the clasp remains centered under the wrist: this is the detail that distinguishes a careful adjustment from a DIY job.
2. Gather the tools
A thin, pointed rod, or a pin punch.
Needle-nose pliers.
A small hammer.
3. Prepare the workspace
Work on a clear, open surface: the pins are tiny and can be lost in a second.
4. Remove the link
Push the pin a few millimeters with the pin punch, then extract it from the other side with pliers or your fingers.
Store each pin: you will need them to close the bracelet back up.
Repeat on the other side of the case if necessary.
5. Reassemble the bracelet
Replace the pins in the middle of the links to be connected, ensuring they enter both holes at the same time.
A light tap with the hammer finishes driving them in if they are resistant.
6. Try it on
If the watch remains too loose, remove one more link. Keep the extra links, pins, and metal rings: they will be useful if you resell the watch or if your wrist size changes.
A grillz is not ordered in centimeters or standard sizes: it is set by impression. The thermoformable putty located on the invisible side of the jewelry molds to your teeth.
The molding process, step by step
Your package contains the jewelry and a pair of tongs.
Bring water to a boil and submerge the grillz for about 15 seconds, just until the putty softens.
Remove it from the water with the provided tongs, never with your fingers.
Place it on your teeth and bite down on the putty to make the impression.
Let it cool. The adjustment is complete.
This operation is reversible and renewable without limit: if the result does not suit you, simply start over.
Never force a piece that does not fit naturally, and remove the jewelry to eat and sleep. In case of persistent discomfort, pain, or gum irritation, seek the advice of a dentist.
It's a classic situation, and it can be handled. In order of reliability:
Borrow a ring that they wear on the same finger, and measure its internal diameter (method 2 above). This is the only truly reliable method.
Choose tolerant jewelry: a necklace, a pendant, or earrings do not depend on any finger measurements.
Pick an all-purpose length: 55 cm for a man, 45 cm for a woman; these two lengths suit the vast majority of cases.
Prefer a bracelet with an extension chain rather than a rigid bangle: the adjustment margin absorbs any errors.
If you have to guess a ring size, don't bet on it: offer another piece of jewelry instead and have them choose the ring afterward.

Frequently Asked Questions
How to know your ring size without a ring sizer?
Wrap the base of the finger with a 6 mm wide strip of paper, mark the meeting point with a pen, unfold the strip, and measure it in millimeters. This number is your direct French size: 54 mm of finger circumference equals size 54.
What does a US ring size correspond to in French size?
On our models, a size 6 US corresponds to a size 52 French, and a size 7 US to a size 54. These equivalents are those displayed on the product pages of our rings; always check the table on the page of the model you are choosing.
What do the letters S, M, and L mean on your rings?
They do not designate the same size from one model to another: on some rings, an M is size 8 US, on others, an M is size 9 US. Never rely on the letter alone; always read the number that follows it on the product page.
Which chain length to choose for a man?
55 cm is the most versatile length: it sits on the upper sternum. Go down to 50 cm for a fit close to the neck, go up to 60 cm and more for an assertive hip-hop style, especially with a wide link.
How much to add to your wrist circumference for a bracelet?
One centimeter for a fitted fit, two centimeters for a comfortable fit, three for a loose fit. On a thick link, aim for two to three centimeters: a wide bracelet worn too tight will ride up on the wrist bone.
Should you size up for a wide ring?
Often yes. Beyond 8 mm of ring width, the contact surface with the skin increases and the ring feels tighter at the same size. A half-size larger restores comfort.
In summary
Three measurements and you have everything: the finger size in millimeters, the wrist size plus the ease, and the chain length that matches your build. Take them calmly, note them down, and you won't make a mistake again.
