*Circumference is the measurement around the base of the finger.
You will need:
- 5mm wide rope
- Fine point pencil
- Ruler

Step 1:
Cut a long strip of paper 5 mm wide.

Step 2:
Wrap the string around the base of the desired finger. For the most precise result, make the string as tight as possible.
*Don't worry! The correct ring size is determined based on a snug measurement. The ring itself won't fit that tight.

Step 3:
Make sure the rope is evenly overlapped and tight, and mark where the two ends of the rope meet.
Step 4:
Measure the length of the string in millimeters. Round to the nearest whole millimeter.
Conversion table:
*We compare size with circumference
