Chart provides a guide to size conversion based on international size measuring conventions and our own fitting experience. However the size required for any one customer can vary significantly from style to style even for the same manufacturer.
This chart does not provide a guarantee of size conversion, it is merely a guide. Customers should consult with us if they are unsure of their required size.
When it comes to rings, one thing is for sure: size matters. Standard ring sizes are given in millimeters based on the inner circumference of the ring. Just like clothing, rings are sized on a standard scale so that a woman’s size 6 is the same from jeweler to jeweler. With that said, if you’ve ever bought jeans from different brands, you are well aware that a clothing size 6 doesn’t always fit the same way – and it’s no different for rings.
Ring sizing becomes a little more complicated when you factor in regional variations. The US and Canada follow a numerical scale with half and quarter sizes; however, other countries may follow an alphabetical scale, which only uses whole sizes or includes a set circumference adjustments. There are also some deviations of ring size charts among jewelers regardless of location. All the jewelers in the world go by two different metrics of sizing. The metrics have to do with the starting point of your ring size – either on the side edge of the ring or the center of the inside of the ring. It’s up to the jewelry company to decide what metric they want to use.
To add one more wrench in ring sizing, the style needs to be considered. Some designs, like those with diamonds all the way around, cannot be sized after they’re designed because it will stretch the metal holding the stones in place, causing them to fall out.
NOTE: If the ring is in between two sizes, choose the larger ring size.

Go For A Snug Fit: As jewelers, we always say the ring should ‘go on easy, come off hard’. This means you have the right fit and the ring is sized properly for the finger, minimizing the risk of loss.
Keep Seasons In Mind: Your fingers tend to change size throughout the course of the year, especially during summer and winter. They’ll swell up a bit during the summer so keep that in mind so the ring doesn’t become uncomfortable to wear during those months.
Consider The Width Of The Band: The wider the band, the tighter it will fit. We recommend going up .25 to .5 size for rings with wider styles.
Warm Up Your Hands: If you’ve just come in from the cold or naturally have colder hands, we recommend warming them to room temperature for the most accurate ring sizing.
Go Big: If you get two different finger measurements or find that a ring you wear often fits differently from time to time, then it’s best to choose a slightly larger ring size, and, if you can, consult a professional.
Because the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device, can only approximate your true shoe size. Please, also keep in mind the manufacturers use different lasts to construct their shoes, and sizing may vary accordingly.
Make sure you are standing, wearing the socks or stockings you will wear with your new shoes. Using one of the following charts, convert your inches measurement to your U.S. shoe size or Euro shoe size.
