Maybe you have something else in mind such as a wedding ring, eternity ring or a friendship ring?

The chart and free ring sizer should help you to determine her finger size without her knowing. If anything, you can have the ring slightly larger. At least you can get this shortened at a later date.
How to measure ring size
1. Ask her parents, they may know her finger size via a ring they purchased for her before.
2. Measure your little finger as a guide.
3. Consider a jeweller who will alter the ring for you after purchase free of charge.
4. Borrow one of her rings and take it to the jewellers so they can measure it for you.
Ring size conversion
