Size guide
Men’s Ring Size Guide (EU 54–75)
Best accuracy: Visit a local jeweler and ask to measure your finger with a metal ring sizer / mandrel. Tell them you need the EU/ISO size (inner circumference in mm).
- Measure the exact finger you’ll wear it on (dominant hand can be slightly larger).
- Measure at the end of the day (fingers swell with heat/activity).
- Wide bands (6–10mm) often feel tighter → consider going up ~½ size.
- If you’re between two sizes, choose the larger one.
