How to measure ring size with the printable Ring Size Chart...
STEP 1:
Download the Printable Ring Size Chart PDF.
STEP 2:
Print the Ring Sizing Chart PDF on A4 paper at 100% sizing.
STEP 3:
Slide an existing ring over the circles and match it to the correct size to find your ring measurement, then refer to the conversion chart included for your Australian sizing. If you don't have a ring, cut out the ruler in the PDF and hold it around your finger to determine the diameter. Remember to set your page scaling to "None" in print settings and check the ruler measures exactly 100mm when printed.
