Finding the right ring size can be a very frustrating task, as it somehow seems that ‘trying the ring until it fits’ is about the right approach when purchasing what is the most popular jewelry piece in the industry.

The nightmare becomes real when you are about to buy a ring for someone else as a gift, and realize that S, M and L sizes are not transferable to rings. Well, let’s end this dilemma once and for all. Rings are so much more than jewelry, especially if you’re looking for an engagement or wedding ring and the ring size shouldn’t hold you back from buying unique pieces online. This goes for any beautiful gold and diamond rings too. 

To help take the stress out of ring buying and to unlock more options for yourself, we’ve put together a handy guide to help you find your ring size and understand ring sizing charts.

Before we get into numbers and charts, it is important to note that, same as with clothing – rings are measured differently depending on a country. As a US based brand, we’ll be explaining more in detail about US ring sizes, however all of the US ring sizes will be converted to EU sizes in our printable ring size chart. 

Understanding Ring Size Charts

When purchasing a ring in the US, you will come across the ring sizes that mostly range from numbers 3-10.5. These numbers correspond to your ring diameter – the inner circle diameter to be more precise. The diameter is measured in mm. The ring size is determined by comparing the diameter of the measured finger to the corresponding number found in the ring chart.

Measuring Ring Size

Find a ring that fits. Make sure it is in the center or the largest area of the circle – this is the diameter. If you wear stackable rings, select one size larger. 

Measuring Using a String

Use a piece of string, or a strip of paper to measure your finger. Use string or paper that’s ½ an inch or 1.4 cm. Wrap it around the base of your finger or the top of your knuckle if you’re aiming for a midi ring. Use a pen or pencil to mark the point where the string or paper overlaps or forms a circle. This should be snug and fitted to your finger but not too tight that it will leave a mark, cut off circulation or slip off. Next, measure the length of the paper or string from the end to the pen mark – this is the measurement of your finger. You can then use the ring chart to determine your ring size in numbers.
