The Hands-on Method

Found the perfect ring? Follow these instructions to find your perfect size.

Grab a tape measure, length of string or strip of paper.
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—and mark the place where it joins.
Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest Tiffany ring 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 Deenie and Flip’s size in mm.

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.

Measure and cut a piece of string to the same length as the necklace you’re eyeing.
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.
