How to Measure Ring Size?
Share
-
Gather Your Tools: You’ll need a piece of string or a strip of paper, a ruler, and a pen.
-
Wrap the String: Take the string or paper and wrap it around the base of your finger. Ensure it’s snug but not too tight. You should be able to slide it over your knuckle comfortably.
-
Mark the Overlap: Use the pen to mark where the string or paper overlaps.
-
Measure the Length: Lay the string or paper flat and use the ruler to measure the length between the start and the mark. This will give you the circumference of your finger.
-
Find Your Size: Use a ring size chart to convert your measurement to the corresponding ring size. Ring size charts are available here.
