RINGS
Option 1 - Measure the diameter of my own ring
- Use a ring that fits the desired finger.
- Measure the internal diameter of the ring (in mm). Ensure your ruler starts at the 0mm mark.
Take a look at the Diameter column in the table and find the closest match in mm to your measurement. Size up if you’re in between two sizes.
Option 2 - Measure the circumference of my finger
- Take a piece of string or cut a thin strip of a paper and wrap it around your finger. Make sure that the string or paper is pulled snug to your finger ( the tighter the better) to find your best fit.
- Mark the spot where the string or paper meets and measure the distance with a ruler (mm).
Take a look at the Circumference column in the table and find the closest match in mm to your measurement. Size up if you’re in between two sizes.
