FINDER: FIT
Ring size finder
Get the number without blowing the surprise, then convert it between US, UK, EU, and millimeters.
Size converter
EU sizes equal the circumference in millimeters, so the conversion is exact; UK letters are the nearest standard size.
Getting the number covertly
- Borrow a ring she wears on that finger and trace the inside on paper several times, or take it to any jeweler for a two-minute read. The gold standard.
- Recruit an accomplice with steady nerves; one casual shopping trip surfaces the size.
- The pen trick: slide her ring onto your finger and mark where it stops.
- Flying blind: most women’s rings land between US 5.5 and 7. Guess a half size large; loose survives the proposal, tight does not.
The safety net
Most rings resize a full size either way, and good sellers include the first adjustment. Exceptions: bands set with stones all the way around, and tension settings. If that is the design, measure twice.
