Sizing

How do I figure out my ring size?

My rings are built to careful specifications based on the millimeter measurement of the inner diameter and circumference, also referred to as the German and ISO standard ring size.  All of my rings are listed in US standard sizes for convenience, in .25 size variations.  Since I build each ring to metric standards I can accommodate any international size as well, below is a chart to convert your ring size to the appropriate US size.

The way a ring fits usually comes down to personal preference, in general though you'll want a ring that slides on the finger without flying off when you shake your hand around.  There's no need to try and shake the ring off your finger to find out though, just make sure there is enough resistance over the knuckle so it stays comfortably in place.

Late afternoon is typically the best time to check your ring size, if you're in a temperate climate expect it to vary between winter and summer by about a .25 size.  If you prefer to keep your ring on all the time then a .25 size tighter may be a good option too.  If even after all the measuring, the ring still doesn't feel quite right when you receive it, I can always resize it for you.

Figuring out your ring size, whenever it's possible, is often best done in person.  If you have a local jeweler that you’re comfortable with you could always have them check your ring size, or the size of a current ring that fits the intended finger.  If you're able to measure the inner diameter of a ring that fits, you can compare it to the chart below. You’re also more than welcome to setup a time to stop by my studio if it's convenient.  I can always mail you a simple sizing kit as well, and I hope to have a more interactive option available in the near future.
