Find Your Ring Size
Take a piece of string and wrap it around the base of your finger.
Mark where the string overlaps with itself for the first time.
Measure the length of the string up to the mark using a measuring tape.
You have measured the circumference of your finger. If in inches, convert it to millimeters.
Divide the circumference by 3.14 (π) to get the diameter of your finger.
Use the ring chart below to find the standard ring size using the diameter of your finger.
