Ring Size Guide
Option #1: Measure By Matching Your Ring
1) Choose a ring that ts the desired nger.
2) Place the ring over the circles below. Match the inside edge of the ring with the closest circle.
This is the inside diameter of the ring.
3) If your ideal t falls between two sizes, we recommend choosing the larger size.
Option #2: Create Your Own Ring Sizer
1) Carefully cut out the paper sizer below. Be sure to make a small slit in the end of the ruler to slide through.
2) Wrap the sizer around your nger with the numbers facing out and slide the rounded end through the slit.
3) For an accurate measurement, pull it snuggly over the widest part of your nger. This could be a knuckle.
4) Read the number that lines up next to the slit. This is your ring size. Keep in mind that quarter sizes are also
available if you sizer indicates that you are between whole or half sizes.
