Ring Size Chart

Anyone who is studying the world of rings for the first time will want to establish a baseline for price, style, material and source. But what about whether it will actually fit on your finger?

Ring sizing seems custom fit for confusion. A size 8 ring in the United States is an 18 in Germany, a 16 in Japan and a Q in the United Kingdom. In all those places, it can be a difficult ring for women to try on in the store because jewelers all over the world often don’t keep it in stock.

Ring Sizes

Finger size fluctuates slightly from day to day and dramatically from season to season. Because hot days, salty meals, pregnancy and arthritis all have their hands on the dial that controls the diameter of your digits, there isn’t necessarily a “perfect fit.” Even if you could arrive at a stable measurement for the part of the finger where the ring is going to sit, you still have to account for variables like the knuckles.

To top all of this off, the person who is buying an engagement ring might be trying to do it on the sly, which makes the process that much more daunting. Finger size can vary from dominant to non-dominant hands, so there’s still going to be a certain amount of guesswork involved. But don’t despair. I am here to help you vault over all your ring sizing obstacles! It’s my pleasure to answer questions about how a ring should fit or whether men’s and women’s sizes are the same.

Working with an experienced jeweler in person is the best path to an accurate ring size, but here is an at home experiment that only requires a pen, a string and a ruler. It’s a good idea to make sure the finger isn’t unusually swollen and to get measured in the morning or afternoon.

1. You will need a pen or pencil, string, and ruler.

2. Take the string and wrap it around your finger.

3. Using a pen/pencil, leave a mark where the ends of the string overlap.

4. Lay the string flat and use a ruler to measure the length in millimeters.

Once you jot down your measurement, you can consult the ring size chart above. It’s generally a better idea to size up rather than down.
