How to Measure
1
Measure an existing ring
Place a ring that fits well on a ruler and measure the inside diameter in millimeters.
2
Use a string or paper
Wrap a string or strip of paper around your finger, mark where it overlaps, and measure the length.
3
Compare to chart
Match your measurement to the chart to find your ring size.
4
Consider the fit
Wider bands typically require a half size larger than narrow bands.
Helpful Tips
Measure your finger at the end of the day when it's at its largest.
Avoid measuring when your hands are cold, as fingers shrink in cold temperatures.
Measure the specific finger you plan to wear the ring on, as sizes vary between fingers.
If you're between sizes, choose the larger size for comfort.
