Measure finger circumference:
For this method you only need a pen, a strip of paper and a ruler.
1. Now wrap a string around the base of your finger.
2. Mark the point where the ends meet with a pen.
3. Now measure the string or paper with a ruler (mm).
4. Finally, choose the closest measurement from the ring size chart.
Use an existing ring :
If you have a ring in the size you would like your new ring to be, you can simply measure the inner diameter or inner circumference of this ring to determine your ring size.
