The right fit
Your jewelry size guide.
A little measuring makes all the difference. Use these guides alongside the dimensions on each product page.
Illustrations compare proportions; they are not life-size. Swipe the earring illustration on smaller screens. Fit varies with body shape and jewelry design. 1 inch = 2.54 cm; 10 mm = 1 cm.
Necklaces · find your length
Lay a necklace you like flat and measure its full length from end to end, including the clasp. To try a new length, place a soft measuring tape around your neck and lower it to your preferred position.
| Length | Approx. cm | Typical look |
|---|---|---|
| 14″ | 35.6 | Close choker |
| 16″ | 40.6 | Near the collarbone |
| 18″ | 45.7 | Below the collarbone |
| 20″ | 50.8 | Longer everyday layer |
| 24″ | 61.0 | Lower statement layer |
Adjustable lengths: a 16″ necklace with a 2″ extender can be worn from 16″ to 18″. A pendant adds a drop below the chain.
Bracelets · leave a little room
Measure around your wrist where the bracelet will sit using a soft tape. For a flexible chain bracelet, adding roughly ½–¾ inch (1.3–1.9 cm) is a useful starting point for comfort. Your preferred fit and the bead size can change this.
| Bracelet length | Centimeters |
|---|---|
| 6″ | 15.2 |
| 6.5″ | 16.5 |
| 7″ | 17.8 |
| 7.5″ | 19.1 |
| 8″ | 20.3 |
Bangles: a closed bangle needs to pass over your hand. Compare its inside diameter with a bangle that fits; wrist circumference alone is not enough. For cuffs, check the opening and the listed internal size.
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 |
