  • Ask his/her friends

As for your partner, there are several tips you can apply when choosing a ring size. One of the best ways you can get this info is to ask their friends and family. They might give you the solution and you solve the mystery.

Even if they don’t know the correct answer, they might ask in a very discrete way to your partner.

Or even another good idea is to take your partner shopping so they can know the correct size and you can order the ring.

  • Borrow A Ring

Another way this can work is to borrow one of your partner’s rings. But you have to be careful about this one, the trick is that he/she doesn't notice the ring is missing, so try to choose one that cannot be noticed right away.

Remember to take it to borrow for max a day. So this doesn’t seem suspicious and then the surprise will be blown away.

But hey don’t panic, below are some valuable facts to guess the right size for your partner.
