Ring Sizer

Easily measure your finger size with this ring sizing gauge.


Ring Sizes

It is not always easy to evaluate the correct size of a ring. The easier way to measure accurately your ring size is to go to a jeweler and ask. If you are in Paris you can visit our flagship store and we can help you out.

Otherwise, the easiest solution is to order a ring sizer here.

The ring sizer works like a belt. Simply push the end through the buckle to form a ring shape. After slip the ring sizer onto your finger. Adjust to give a comfortable fit, checking that it just slips back over the knuckle. When best fit is achieved, read off size indicated by the arrow. The ring sizer uses US standard sizes, you can look for the matching French size on the internet or just send us an email and we'll do it for you.

Free shipping to France, Belgium and Luxembourg.

Easily find your finger size

Our ring sizer uses American sizes and half size, we also provide a sheet to find their equivalent European sizes.

Buying a ring online can be a daunting task, especially if you are unsure of your finger size. Even if you know your ring size, how will you know for sure if a ring will fit you perfectly without trying it on first?

Our recommendation

This ring sizer is incredibly intuitive to use. We recommend that you find a size that is not too tight and that fits comfortably on your finger. You don't want the ring sizer to be too loose but to fit comfortably through your knuckle.


To get your size, form a circle passing the end through the hole.

Place the ring sizer over the finger you wish to measure and tighten it by pulling on the end until you find a comfortable size that fits you.

Make sure that the ring sizer can be put on and taken off comfortably but with a little resistance.

The ring sizer measures in half sizes up to 17. (It can get a little confusing after size 10. If you are not sure about your size, send us a picture of the sizer on your finger)

We also recommend that you confirm your ring sizer with a jeweler.

If you have any questions or have trouble finding the right size, don't hesitate to contact us at
