How to Know Your Ring Size: Simple and Practical Guide
It is often difficult to accurately determine your ring size, especially when you want to make a purchase online or give a piece of jewelry to a loved one. In this article, we offer practical tips for knowing your ring size accurately and easily. And rest assured, even if you can't find your exact size, there are adjustable rings that can save the day!

Step 1: Measure your finger
The first step to knowing your ring size is to measure your finger. To do this, simply use a seamstress's tape, string or even a piece of paper.
Wrap the string around the base of your finger, without tightening too much so as not to distort the measurement. Mark where the string crosses with a pen. Then simply measure the string with a ruler. This corresponds to the circumference of your finger. Please keep the measurement in millimeters.

Step 2: Convert the measurement
Once you have the circumference of your finger, all that's left to do is use it to find out your ring size.
For France, the ring size corresponds directly to the circumference of the finger in millimeters. So if your finger circumference is 54mm, your French ring size will be 54.
For finger diameter, divide the circumference of your finger by π (pi, approximately 3.14). So if your circumference is 46mm, your finger diameter would be approximately 14.6mm.
For the United States and Canada, ring sizes are usually expressed in whole numbers and half sizes. A conversion chart will help you convert your finger circumference to ring size. For example, a US ring size of 7 corresponds to a finger circumference of approximately 54mm.
For the United Kingdom, ring sizes are expressed in letters of the alphabet, from size A to size Z, with half sizes for accuracy. For example, a UK ring size M corresponds to a finger circumference of approximately 52.5mm.

Step 3: Purchasing abroad? View a conversion table
Here is a conversion table to make it easier for you. Please note that ring sizes for the US and UK have been rounded to the nearest quarter size for a more accurate conversion. These conversions may vary slightly depending on the source.

When to measure your finger?
It is recommended to measure your finger at the end of the day. Indeed, at the end of the day your fingers (and your feet for that matter) are at their maximum size. Also, if you are too hot or too cold, your finger sizes may be different. It is best to avoid measuring your finger after strenuous physical activity or during a long walk in winter or summer.
What if I can't find my exact size?
Don't worry ! If you are in doubt about the ring size you are getting or you don't know the ring size of the person you want to give a ring to, there is a solution: adjustable rings.
