Find Your Ring Size
The Hands-On Method
Measure Your Finger
- Use a flexible measuring tape or length of string.
- Wrap it around the finger you’ll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.
- Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the Tiffany size chart above to determine your ring size. If you are between sizes, opt for the larger size.
Measure an Existing Ring
A helpful method if you’re surprising someone with a gift or treating yourself.
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart above to match the size of your ring to the closest Tiffany size in mm. The interior of the ring should align with the outer edge of the circle.
Now follow the ring size chart below to determine your size with the measurements taken from above mentioned methods

Find Your Bracelet Size
Measure Your Wrist
Size your cuffs and bangles to fit snugly, and your link and chain bracelets to fit slightly loosely to allow for movement.
- Use a flexible measuring tape or length of string.
- Wrap it around the thickest part of the wrist (usually at the wrist joint). If using string, mark the point on the string where the ends meet with a pen. If you are creating a bracelet stack, measure the point on your arm where you’ll wear each bracelet.
- Lay the string on a flat surface and use a ruler to measure the length (in inches or centimeters) up to the mark. Compare your measurement to the Tiffany size chart above to determine your bracelet size. If you are between sizes, opt for the larger size.
| Tiffany Size | Wrist Diameter (in) | Wrist Diameter (cm) |
|---|---|---|
| Extra Small | 4.76 – 5.25 | 12.1 – 13.3 |
| Small | 5.26 – 5.75 | 13.4 – 14.6 |
| Medium | 5.76 – 6.25 | 14.6 – 15.9 |
| Large | 6.26 – 6.75 | 15.9 – 17.1 |
| Extra Large | 6.76 – 7.25 | 17.2 – 18.4 |
| Extra Extra Large | 7.26 – 7.75 | 18.4 – 19.7 |
| Extra Extra Extra Large | 7.76 – 8.25 | 19.7 – 21 |
Find Your Necklace and Pendant Length
Necklaces vary by chain length. The circumference of your neck and size of the pendant will impact how your necklace sits on its own and with other styles.
- Measure and cut a piece of string to the same length as the necklace you’re interested in.
- Place it around your neck to see where it falls—the key to layering is striking the right balance. Consider the size and shape of the pendant.
- Repeat the process to see how necklaces of different lengths may look together.
| Length (in) | Length (cm) |
|---|---|
| 16 | 40.50 |
| 18 | 45.75 |
| 20 | 50.75 |
| 24 | 61.00 |
| 30 | 76.25 |
| 36 | 91.50 |
