| Determining Your Ring Size |
| If you don't know your ring size follow these instructions and you will be able to determine it. |
| |
1. Cut a strip of paper no wider than 1/4" .
2. Wrap the paper snugly around your finger and mark the paper where it meets.
3. Measure the marked length of paper and compare it to the chart below.
Note: If your knuckle is significantly larger than the base of your finger, you should measure the knuckle as described above and pick a size somewhere in between.
This should give you a good idea of your ring size.
