METHOD 2 (Measuring your finger)
1. Take a piece of string and wrap it around your finger, at the point at which the ring will sit.
2. Tighten the string to a comfortable tension, not too tight and not too loose.
3. Use a marker to mark where the string overlaps to record the circumference.
4. Using a ruler, place the string alongside to record a measurement of its length in MM.
5. Using the conversion chart below, convert the MM circumference to AU/US ring size.
