Method 1
-
Choose a ring that fits comfortably on your finger.
-
Measure the internal diameter with a ruler. Make sure to start measuring from the 0 mm mark.
-
Match your measurement against the internal diameter chart to determine your size.
Method 2
-
Use a piece of string or a strip of paper.
-
Wrap it around the finger you want to wear the ring on and mark the point where the ends meet.
-
Lay the string or paper flat against a ruler and measure from the start to the mark. This gives you the circumference.
-
Match that measurement against the circumference chart to find your size.
