Ring sizing chart

The chart below is for reference only and is not to scale. 

To measure your finger size take a ring you currently own measure the inside diameter of the ring using a tape or ruler with millimeter markings.

To get the most accurate measurement use a solid ruler rather than a tape which could bend and give an incorrect reading.

From the measurement refer to the chart below to get your correct finger size.

Most measurements won't match the chart exactly therefore order the full size closest to your measurement.
