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.

Bracelet Size Guide

To choose the right size for your bracelet, follow these simplified steps:

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.

  1. Use a flexible measuring tape or length of string.
  2. 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.
  3. 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.
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

Necklace Size Guide

The Long and the Short of It

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.

Necklaces

To get the best fit, we recommend measuring your neck to where you want the necklace to fall. You can use a sewing tape measurer to achieve this. If you do not have one, you can use a common household item, such as headphones, charging wires, or a piece of string/yarn - then measuring that household item with a ruler. 

You can use this chart to help guide you, but everyone has different sized necks, so please use this knowing that it might not be accurate for you. 

Sizing according to the chart:

  • 12-14": Choker size
  • 14": Falls right at the base of the neck.
  • 16": Hits around the collar bone.
  • 18": Most popular length for pendants.
  • 20": Falls right above the cleavage.
