The perfect ring is the one that fits comfortably on your finger. The international ring size conversion chart allows you to determine and compare ring parameters across six different regions of the world.
If you're an American citizen, and you're traveling abroad, you can often get confused by the multiple standards available in contemporary jewelry. Rings sizes are a frequent issue.
There are two fundamental variables when it comes to choosing the perfect ring for your fingers - the inside circumference, and the inside diameter. With six different scales (British & Australian, US & Canada, French & Russian, German, Japanese, and Swiss), confusion reigns.
A ring should never be too loose, nor too tight. There's a perfect test you can do - if the ring fits over the knuckle, everything's good. You should also take into consideration the fact that in warm weather expand your fingers, and cold weather contracts them.
Additionally, remember that if you're hesitant between two sizes, you should always pick the larger one. The ring size chart applies to both women and men. However, the average woman's ring size is 6, while the average man's ring size is roughly 10.
Interestingly, your ring size is approximately half a size larger on the hand you write with. If you don't know your ring size, there's another way of knowing which one fits you.
The printable ring guide will help you choosing the perfect model. Download it.
Now, check the right ring for your finger:
