Choosing the perfect ring size is essential to ensure both comfort and aesthetics. A ring that is too tight can be uncomfortable, while one that is too loose risks slipping off. Here is a detailed guide to help you determine the ideal size.
Understanding Ring Size Systems
Ring sizes vary by country. It is important to first understand the system used in your country or by the jeweler where you are purchasing.
-
France, Germany, and Belgium
Sizes are measured in millimeters, corresponding to the inner circumference of the ring.
01 -
Italy, Spain, Netherlands, and Switzerland
Sizes are determined by subtracting 40 from the circumference in millimeters. For example, a circumference of 54 mm corresponds to a Swiss size of 14 (54 - 40 = 14).
02 -
United Kingdom
Sizes are indicated by letters from A to Z.
03 -
United States
Sizes are numbered from 1 to 13 for women.

Measuring Your Ring Size
Method #1: Measure an Existing Ring
If you have a ring that fits perfectly, place it on our printed ring sizer in A4 format and find the circle that matches the size of your ring. The circle should align with the inner edges of your ring.
You can also measure its inner diameter with a millimeter ruler. Then, multiply this diameter by π (3.14) to obtain the circumference.
Method #2: Use a Measuring Tool
There are various ring size measuring tools available online or in jewelry stores. These tools are usually designed in the form of a plastic or metal circle that can be adjusted to your finger size. Simply follow the instructions provided with the tool to determine your ring size.
Method #3: Use a Paper Strip or Ribbon
If you don't have a properly fitting ring or a measuring tool, you can use a string, thread, or a paper strip a few millimeters wide to measure your ring size. Wrap the string around your finger snugly and mark where the ends overlap. Measure the length between the marks on a ruler to get the length in millimeters.
If you are unsure between two sizes, it is generally recommended to choose the larger size for comfort.
Important Considerations When Measuring Your Ring Size
Size Can Vary Depending on the Time of Day
It is important to note that the size of your finger can vary depending on temperature and humidity, as well as factors such as exercise and weight changes.
It is therefore recommended to measure your finger at different times of the day and in various conditions to get an accurate estimate of your ring size.
Measure the Hand That Will Wear the Ring
Fingers on the dominant hand are usually slightly larger. Make sure to measure the finger on the hand where you will wear the ring.
Consider the Width of the Ring
Wider rings often require a slightly larger size for optimal comfort.
