size guide
All Mantor rings are measured in EU sizing (inner circumference in millimeters).
Note:
Due to the solid, wide-profile design of our rings, they fit snugger than standard thin bands. If you are between two sizes, we recommend selecting one size up.

How to Measure
Option 1: Measure an existing ring
Place a ring that fits you well flat on a ruler and measure the inside diameter in millimeters (excluding the metal).
Option 2: Measure your finger
Wrap a strip of paper around the base of your finger or knuckle, mark where it overlaps, and measure the length in millimeters against a ruler. That measurement corresponds to your EU size.
Fit Tips
- If your knuckle is wider than the base of your finger, pick a size between both measurements so the ring slides over smoothly.
- Measure at room temperature in the late afternoon, as fingers can be slightly slimmer in the morning or cold weather.
