One retailer guide states that Gucci rings run true to size, and advises going up a size if you are between sizes. Gucci ring numbers follow the Italian system, which equals the EU size minus 40. Gucci 12 is EU 52 and US 6, and Gucci 20 is EU 60 and US 9.
Gucci Ring Size Chart (IT 9 to 27)
Gucci rings are made in Italy, so the size on the ring is an IT number. The EU size is the inner circumference in millimetres (ISO 8653), and Gucci IT = EU – 40. The exact US size is calculated from that circumference. The last column shows the US size that one retailer lists for the same Gucci number.
| Gucci IT | EU (circumference mm) | Inner diameter (mm) | Exact US size | Nearest US half size | Nearest UK size | Retailer-listed US |

The calculated and retailer-listed values agree within a quarter size. Gucci lists quarter sizes, so use the Gucci number when ordering and use the US column as a guide. For the Gucci printable sizer, see our Gucci ring size chart, and for other systems see the ring size conversion chart.
Do Gucci Rings Run Big or Small?
The size-charts.com Gucci guide says Gucci rings run true to size, and that you should go up to the next size if you are between sizes. That is one third-party source, not Gucci. We did not find size-fit data for individual models such as the Interlocking G or the Trademark ring, so check the product page for the model you want. A wide band usually fits tighter than a thin one, so read choosing the right wide band ring sizer before buying.
How to Find Your Gucci Ring Size
- Measure a ring that fits you. Lay it flat and measure the inside width in millimetres, then match it in the chart. See the mm to ring size chart.
- Or wrap a string or paper strip around your finger, mark the overlap, measure the length in mm and match it to the EU column.
- Measure at different times of day, because fingers swell with heat, and average the readings.
- If you have large knuckles, order half a size larger. If you fall between sizes, choose the larger one.
Gucci also offers a printable sizer: cut out the outline, make a slit at the left end, wrap it around your finger with the numbers facing out, slide the pointer through the slit and read the number at the slit. Our how to measure your ring size guide covers other methods.

Gucci Ring Size Bands
The same retailer lists Italian size bands from Gucci: XXS is 8 to 10, XS is 10 to 12, S is 13 to 15, M is 16 to 18, L is 19 to 22 and XL is 23. Use the numbers rather than letters when you order, because a letter covers several sizes.
