What Size is Your Ring Finger?
1. Find a piece of string or strip of paper no wider than 3/4″.
2. Wrap it around the base of the appropriate finger.
3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
5. Use this measurement and the information below to determine your ring size.
Tip: Don’t measure when your fingers are cold, because they’re smallest at that time. It’s best to measure them at the end of the day.
