Frequently Asked Questions

Find here the answers to the most frequently asked questions about measuring your ring size and understanding international size conversions.

How can I measure my ring size?

You can measure the circumference of your finger using a soft measuring tape, a strip of paper, or a piece of string, then compare that measurement in millimetres with the ring size guide.

What should I do if I am between two sizes?

If you are between two sizes, it is generally recommended to choose the larger one, especially if your ring is wide or if your fingers tend to swell during the day.

What is the difference between inner circumference and inner diameter?

The inner circumference is the complete inner measurement around the ring, expressed in millimetres. The inner diameter is the inner width of the ring measured from one side to the other, also in millimetres.

Are ring sizes the same in every country?

No. Ring size systems vary from country to country. That is why the guide shows the equivalences between several international sizing systems, including France, the US, Canada, and Spain.

What is the best time of day to measure my finger?

It is best to measure your finger when your hands are neither too cold nor too warm, at the end of the day, when your finger size is most representative.

Can I use a ring I already own?

Yes. If you already have a ring that fits well, you can measure its inner diameter and compare it with the conversion chart.

Why can my ring size vary?

Finger size can vary depending on the outside temperature and the temperature of your hands, hydration, the time of day, and even which hand you are using.

Does this guide guarantee a perfect size?

This guide helps estimate the most suitable size, but comfort may vary depending on the shape of the ring, its width, and your body shape.
