Ring Size Conversion Chart

Measuring ring size is best done with a set of master ring sizes, preferably with metal bands. Most jewelry stores offer this free service, just like most shoe stores will size you at no charge. If you can't make it to a store or are trying to keep the ring a surprise, you can measure the circumference of his/her finger in millimeters and then use the chart to obtain the ring size accurately.

While ring size is a standard measurement and size, men's rings tend to be wider, which needs to be accounted for when obtaining a ring size. We recommend using thicker bands or sizers for men to get an accurate size. In contrast, using a thinner sizing ring or band is advisable for most women's rings.

Most stores and retailers offer quarter sizes to ensure the sizing is correct if you're between sizes. No two fingers are the same, and no finger is perfectly circular, so make sure the retailer offers free resizing should you need a size adjustment.

Factors like weight gain, weight loss, temperature, and water retention can affect finger size. There is also a chance that pregnant women will have a temporary size fluctuation towards the end of their pregnancy.

While the chart provides general guidelines, individual fit can vary. It's always best to get sized professional at a store (this service is traditionally free).

If you have a ring that fits well, you can measure its inner diameter and compare it to our ring size chart.
