Finding her ring size without giving it away
The size is the one detail you cannot see in a photo. Here is how to get close without spoiling the surprise.

Five quiet ways
- Borrow a ring she wears on her ring finger and trace the inside on paper — or bring it to us
- Ask a close friend or family member to find out casually
- Press a ring she owns into a bar of soap to keep an impression
- Compare her ring against your own finger and note where it stops
- Notice the size on any ring she has had resized before
Which hand, which finger
Dominant hands are often slightly larger, and fingers swell in warm weather and at the end of the day. If a borrowed ring comes from her right hand, the left ring finger is usually a touch smaller.
If you guess, guess up
A ring that is a little large can be worn safely until it is adjusted; one that is too small cannot be put on at all. When in doubt, choose half a size larger.
Resizing is part of our lifetime care — so a near guess is perfectly fine.
Not sure at all? Choose "I don't know my ring size" when you build the ring and we will size it together after the proposal.
Ready when you are.
