How to measure my ring size using a measuring tape?
Using a measuring tape (or piece of string, to be measured against a ruler later) is an accurate way to find your ring size in inches. Wrap the measuring tape around the base of your finger. You want the tape to feel snug, but not tight. Use a pen to mark the tape or cut the small piece of string. Then, simply measure the string, or see how many millimeters it took to wrap around your finger. Finally, simply reference our easy ring size chart to find your perfect ring size.
The best time to try this is at the end of the day, when your fingers are likely to be at their largest.
