Ring Size Guide

Find Your Ring Size  

Choose one of these three easy mothods to find out your perfect Sissai ring size:

1. Ring size guide: Open and print our ring size guide in PDF here.

2. Finger circumference: Fit your finger with a thin piece of paper or string and then measure with a ruler to find the millimeters. Use the number of millimeters to validate your ring size in the chart below. If your ideal fit falls between two sizes, we recommend choosing the larger one.

For example: If your measurement in millimeters is 45.4, then your ring size is 3 ½.

3. Ring diameter: If you already have a ring that fits you well, you can measure the ring diameter directly with a ruler. Just take the ruler and measure the center of your ring, from edge to edge. Take your ring diameter in millimeters and use our guide chart below to find out your ring size. If your ideal fit falls between two sizes, we recommend that you choose the larger one.

For example: If your measurement is 49 millimeters, then your ring size is 5.
