The Hands-on Method
Found the perfect ring? Follow these instructions to find your perfect size.
1. Grab a tape measure, length of string or strip of paper.
 
2. 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.
 
3. 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 Jayzoff ring size.

Bracelets Size Chart 

It’s All in the Wrist

Size your cuffs and bangles to fit snugly, and your link and chain bracelets with a touch of breathing room to allow for movement.
1. Grab a tape measure, length of string or strip of paper.
 
2. Wrap it around the wrist you’ll wear your bracelet on. Mark the place where it joins. Creating a stack? Measure where on your arm you’ll wear each bracelet.

 Necklaces Size Chart

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.
1. Measure and cut a piece of string to the same length as the necklace you’re eyeing.
 
2. 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.
 
3. Repeat the process to see how necklaces of different lengths may look together.
