Measuring Ring Sizes

 

To determine your ring size, cut a strip of paper approximately 5mm wide by 5 inches long. Wrap the paper around your finger and using a pen, mark where the long end overlaps. Measure the marked length (in millimeters for better accuracy) with a ruler, then use the table below to determine the closest US size.

 

Be aware that if you have a large knuckle, you will need to be able to slide the ring past it. Also keep in mind that finger size will be affected by the normal swelling and shrinking caused by hot or cold weather, physical exercise, etc. If you are ordering a wider band, you may want to increase the size slightly.
