Identity Boutik / The right fit
Jewelry size guide.
Find your length. Find your fit. Necklace and bracelet guidance for women, men and kids, with measurements in inches and centimeters.
These are general fit references, not a promise of where a piece will sit. Neck size, wrist size, height, body shape, beads and pendants all affect fit. Check the actual length and adjustment range on each product page. The guide does not mean every style is available in every length.
01 / Necklaces
Seven lengths. Different ways to wear them.
Measure a piece you love
Open the clasp, lay the necklace flat and measure end to end, including the clasp. Measure an extender separately unless the product states that it is included.
Preview a new length
For an adult, use a soft tape or a piece of string cut to the full necklace length. Drape it loosely around the neck and check the fall in a mirror. Never pull it tight.
Allow for the details
A pendant hangs below the chain; it is not usually part of the chain-length measurement. A 16-inch chain with a 2-inch extender can adjust from 16 to 18 inches.
The number is the full necklace length around the neck, not the distance from your neck down to the pendant. Each 2-inch step adds 5.1 cm of chain.

Women’s size guide
Use the illustration to compare short and long styles, then measure on your own body. A broader neck or chest makes the same chain sit higher.
Necklace lengths
| Length | Metric | How it may sit |
|---|---|---|
| 14 in | 35.6 cm | Close choker; check neck circumference. |
| 16 in | 40.6 cm | Short, near the base of the neck or collarbone. |
| 18 in | 45.7 cm | Classic length, often at or just below the collarbone. |
| 20 in | 50.8 cm | A little lower on the upper chest. |
| 22 in | 55.9 cm | A longer layer over the upper chest. |
| 24 in | 61.0 cm | A low chest layer; placement depends on your torso. |
| 36 in | 91.4 cm | Long rope style, often below the bust. |
Women’s bracelets
A common adult reference is 6½–7½ inches of finished length. Choose by wrist measurement, even when it falls outside that range.
| Measured wrist | Chain bracelet example (wrist + ½ in) |
|---|---|
| 5.5 in 14.0 cm | 6 in 15.2 cm |
| 6 in 15.2 cm | 6.5 in 16.5 cm |
| 6.5 in 16.5 cm | 7 in 17.8 cm |
| 7 in 17.8 cm | 7.5 in 19.1 cm |
| 7.5 in 19.1 cm | 8 in 20.3 cm |
Measure your wrist, then allow room for the bracelet design. Read the bracelet measuring instructions.

Necklace lengths
| Length | Metric | How it may sit |
|---|---|---|
| 14 in | 35.6 cm | Usually too short for an adult neck; measure before choosing. |
| 16 in | 40.6 cm | A close fit on a smaller neck; may be too tight. |
| 18 in | 45.7 cm | A short chain around the base of the neck. |
| 20 in | 50.8 cm | An everyday chain around the collarbone or upper chest. |
| 22 in | 55.9 cm | A relaxed chain below the collarbone. |
| 24 in | 61.0 cm | A longer chain over the chest. |
| 36 in | 91.4 cm | An extra-long chain over the lower chest or torso. |
Men’s bracelets
A common adult reference is 7½–9 inches of finished length. Larger wrists and substantial links can need extra room.
| Measured wrist | Chain bracelet example (wrist + ½ in) |
|---|---|
| 6.5 in 16.5 cm | 7 in 17.8 cm |
| 7 in 17.8 cm | 7.5 in 19.1 cm |
| 7.5 in 19.1 cm | 8 in 20.3 cm |
| 8 in 20.3 cm | 8.5 in 21.6 cm |
| 8.5 in 21.6 cm | 9 in 22.9 cm |
Measure your wrist, then allow room for the bracelet design. Read the bracelet measuring instructions.
02 / Bracelets
Start with your wrist measurement.
1. Measure
Wrap a soft tape around the wrist where the bracelet will sit. Keep it comfortably against the skin without squeezing. Or mark a strip of paper and measure it with a ruler.
2. Allow room
For a fine chain or link bracelet, adding ½ inch (1.3 cm) is a starting point. A fuller bead or charm bracelet may need more room. Follow the individual product’s sizing notes.
3. Check the fit
The finished bracelet should move comfortably without slipping over the hand. For an adjustable style, make sure your desired length falls within its stated range.
The examples below add ½ inch to a measured wrist. They are starting estimates for flexible chain bracelets, not fixed sizes for every design.
Bangles, cuffs and beads
Closed bangles: the opening must pass over your hand. Compare the inside diameter with a bangle that already fits; wrist circumference alone is not enough.
Cuffs: check the internal dimensions and opening. Avoid repeatedly bending a cuff unless the product specifically allows adjustment.
Beads and charms: larger beads reduce usable internal space. A listed end-to-end length can feel snugger than a fine chain of the same length. Ask us about the exact design if you are between sizes.
03 / Kids
Kids’ size guide
The same measuring method applies to boys and girls. Age or gender alone cannot determine a child’s size. An adult should measure the child, check the product’s intended age range and supervise wear.
Kids’ necklaces
Measure a well-fitting necklace off the child, or ask us for help with the specific piece. Use these lengths for comparison, not as age-based recommendations.
| Length | What to compare |
|---|---|
| 14 in35.6 cm | A shorter length; check that it is comfortably loose for the individual wearer. |
| 16 in40.6 cm | Adds 2 inches (5.1 cm) of chain compared with 14 inches and hangs lower on the same child. |
| 18 in45.7 cm | Adds another 2 inches; may be a longer style or fit an older child, depending on their measurements. |
| 20–36 in | Long adult-style lengths. Do not select these for a child without checking the fit and the product’s suitability. |
Kids’ bracelets
Measure the wrist each time you order. These chain-bracelet examples are based on the measurement, not an age band. The bracelet should not pinch or slide off.
| Measured wrist | Chain bracelet example (wrist + ½ in) |
|---|---|
| 4 in 10.2 cm | 4.5 in 11.4 cm |
| 4.5 in 11.4 cm | 5 in 12.7 cm |
| 5 in 12.7 cm | 5.5 in 14.0 cm |
| 5.5 in 14.0 cm | 6 in 15.2 cm |
| 6 in 15.2 cm | 6.5 in 16.5 cm |
For parents: Jewelry is not for infant wear or teething. Remove children’s jewelry for sleep and active play, and keep loose beads and small parts away from young children. Follow the product’s age and safety guidance.
Earrings · understand the scale
Compare the millimeter dimensions with a pair you already own. Stud size is usually the face width; hoops may list an inner or outer diameter. Drop length is measured from the top of the earring to its lowest point. Check which measurement the product provides.
Studs
4–6 mm gives a small accent. 8 mm creates a more noticeable face. Shape and setting affect the overall look.
Hoops
10–15 mm is compact; 20–30 mm adds presence; 40 mm feels bolder. A huggie’s fit also depends on your piercing placement.
Drops
Check total length and width. A 30 mm drop is 3 cm long; compare it with your usual earrings using a ruler.
Rings · measure the inside
For the most reliable fit, ask a jeweler to size the intended finger. As a starting estimate, measure the inside diameter of a well-fitting ring across its center, without including the metal band.
Wide bands may feel tighter. Temperature, time of day and your knuckle can affect fit. Do not assume an adjustable ring fits every finger or that every ring can be resized.
This is an approximate U.S. reference chart, not a printable ring sizer. Use the sizing system stated on the product page.
| U.S. size | Inside diameter (mm) | Inside circumference (mm) |
|---|---|---|
| 4 | 14.9 | 46.8 |
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.9 |
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 57.0 |
| 9 | 19.0 | 59.5 |
| 10 | 19.8 | 62.1 |
| 11 | 20.6 | 64.6 |
| 12 | 21.4 | 67.2 |
