[Rings] About the size of Hermes rings

When it comes to Hermes accessories, bracelets such as the Chaine d'Ancre are especially popular, but in recent years, rings have also been gaining a lot of attention. There are also valuable vintage models that are no longer in production, as well as rare models that are currently in circulation but are hard to find in boutiques.
In this article, we will provide detailed information about the size of Hermes rings, a topic that customers often ask about.
Hermes ring size chart
Hermes rings are sized according to the European size standard (ISO standard), which has slightly different rules than the Japanese size standard (JCS standard).
For details, please refer to the quick reference chart below, but roughly speaking, the number obtained by subtracting 40 from the European standard size will roughly conform to the Japanese standard size.
For example, the Hermes size "#52" corresponds to "approximately size 11.5" according to the JCS standard.
On our product pages, if the item is eligible for size labeling, we list the manufacturer's official size number (※), and also post images of measurements taken using a ring gauge stick.
(*For some vintage models and other items that do not have a size label, we have listed the actual size measured by our company.)
Hermes notation (ISO standard) | Inner circumference of ring (mm) | Size based on JCS standards |

46 | 46.1 | Approximately No. 6 |
47 | 47.1 | Approximately No. 7 |
48 | 48.2 | Approximately No. 8 |
49 | 49.2 | Approximately No. 9 |
50 | 50.3 | Approximately No. 9.5 |
51 | 51.3 | Approximately No. 10.5 |
52 | 52.4 | Approximately No. 11.5 |
53 | 53.4 | Approximately No. 12.5 |
54 | 54.5 | Approximately No. 13.5 |
55 | 55.5 | Approximately No. 14.5 |
56 | 56.6 | Approximately No. 15.5 |
57 | 57.6 | Approx. 16-16.5 |
58 | 58.6 | Approx. 17-17.5 |
59 | 59.7 | Approximately 18-18.5 size |
60 | 60.7 | Approximately No. 19 |

62 | 62.8 | Approximately No. 21 |
63 | 63.9 | Approximately No. 22 |
Models whose size and actual fit may differ
Hermes rings come in a variety of motifs, and for certain models, the stated size may differ from the actual fit.
Example 1. Chaine d'Ancre Enchaine Ring

The Chaine d'Ancre Enchaine ring comes in two models: the narrow "PM" and the wide "GM", and even if they are the same size, the fit will be different.
When a staff member with a ring finger size of about 16 tried it on,
For "PM", "#57" was the perfect size, but for "GM", "#58" was the perfect size.
The Chaine d'Ancre Enchaine Ring GM is an open ring design, so there may be slight individual differences, but we recommend going up one size from your finger size.
Example 2. Collier de Sian ring

The Collier de Chien ring also comes in two models, and just like the Enchaine ring, the feel of wearing one will be different between "PM" and "GM" even if they are the same size.
When a staff member with a pinky finger size 11 tried it on,
For the PM, size #52 was the perfect fit, but for the GM, size #53 was a little tight to almost the perfect fit.
I feel that if I go up two sizes to size #54, I can wear it comfortably.
Unlike the Enchaine Ring GM mentioned above, this ring has a closed ring and a wide design, which gives it a secure fit, so we recommend going up 1 to 2 sizes from your finger size.
Example 3. Osmos Ring

Although the Osmoz appears to be a relatively wide motif, it is a somewhat versatile model due to its tapered shape towards the palm and its open ring design.
A staff member with a middle finger size of approximately 18 tried it on and found that it also fit size #57.
Osmoz rings are rarely available in larger sizes, so if you come across a ring that is close to the size of your finger, we recommend that you try it on.
Models where the gauge stick measurements differ from the actual wear experience
Some vintage Hermès rings have a more handmade feel than current models, and because the inner circumference is not a perfect circle, the measurements taken with a gauge stick may differ from the actual feel when worn.
A typical example is the "Diane Ring," which we often carry in our store.
Other famous motifs include the "Bouclesellier Ring," "Duzaneau Ring," and "Mexican Corset Ring," which also have slightly oval inner circumferences.
The fit is generally the same as the stated size, but because of the oval shape, there is a slight feeling of tightness when putting on and taking off the garment.
If the motif is narrow, please choose the size that is just your finger size or one size up.
For wider motifs, we recommend going up 1 to 2 sizes from your finger size.
summary
I have explained the size and feel of Hermes rings, but I think the best way to find out is to try them on for yourself.
