Ring Sizing Guide

Most Luca Jouel rings can be made in any size requested.

In determining your ring sizes please note the following:

  • a ring should fit your finger comfortably, fitted enough so that it will not fall off, but loose enough to slide over your knuckle
  • your finger size can change throughout the day so it is best to measure at the end of the day when your fingers are at their largest
  • your fingers will be at least half a size smaller if you measure when they are cold
  • rings of the same size may have a slightly different fit depending on their design; specifically wide bands generally require a slightly larger size for most people 
  • full circle diamond bands are not able to be re-sized up or down so accuracy of fit is particularly important to know before ordering to avoid unnecessary returns
  • sizing is also prohibited for some setting styles because the act of doing so would distort the setting
  • we highly recommend visiting your local jeweller as the most accurate way to find out your ring size

Please see below a table of the most common ring sizes. The most commonly purchased women’s ring sizes tend to be sizes 5 to 7, with size 6 being the most popular. 
Men’s rings typically range from size 8 to 14, with size 9 being the most commonly purchased.
