To determine your ring size, you measure your finger:
- Use a length of string, ribbon or dental floss and wrap it around the base of your finger
- Use a pen to mark the point on the string when the end meets
- Use a ruler to measure the string, in millimeters
- Use the chart to find your size: choose the closest measurement to the chart, and if you appear to be between two sizes, we recommend choosing the largest size
- You can measure your knuckle as well to ensure you select a size that will slide on and off your finger easily
Measure existing rings
- In your 'printing settings', ensure that 'page scaling' is set on 'none' before you print
- The ring size chart should be printed in a full "A4 (81/2x11 inches)" size page, you can check the printing scale measuring the samples below
- Use a regular ring that perfectly fits and place it on the circles below: the outline of your ring should meet perfectly the circumference of the circle
- Choose the matching size in the conversion chart
