Using a String to Measure Your Finger:
1. Wrap a piece of string or floss around the base of your finger. Keep in mind that string and floss can stretch, so try not to pull your measuring tool too tight.
2. Mark on the string where it first overlaps on your finger using a pen or marker.
3. Measure the length from the start of the string to the pen mark with a ruler, taking down its length in millimeters.
4. Use the Ring Size Chart to match the millimeter length to the corresponding ring size.
