How do I know what size of ring to buy?
If you are buying a ring online and do not want to go to a jewelry store just to measure ring size, here’s how you can do it from home.
How to determine your ring size from home:
1) Take a piece of string or dental floss and wrap it around the base of your finger.
2) Mark the point on the string where the end meets.
3) Measure the string with a ruler using millimeters.
4) Use the table below to find the closest measurement to your ring size.
Tips to ensure you get it right:
– Make sure you leave enough room for the ring to fit over your knuckle.
– Different fingers may have different sizes. Make sure you measure the specific finger you will be wearing your ring on.
– Measure your finger at the end of the day when your finger is likely to be largest.
