Ring Size Guide
Step 1
Wrap a measuring tape or piece of string around the finger where you plan to wear the ring. Make sure the tape or string is snug—not too tight, not too loose.
Step 2
Mark where the tape or string meets. If you are using string, cut it at the marked point to measure the circumference.
Step 3
Measure the length of the string or ribbon with a ruler to get the circumference. Place the ribbon or string on a flat surface and use a ruler to measure the length.
Step 4
Use the chart below to find the ring size that matches your diameter. Refer to the chart to convert your circumference to the most appropriate ring size.
Helpful Tip: Measure your finger at the end of the day, when it is slightly more dilated, to ensure a perfect fit. Avoid measuring your fingers when they are too cold or too hot, as this may affect the result.
