Phone a friend.Her friend might have bought her a ring before. It’s also very likely the topic of engagement rings could have popped up in a conversation with her friends.
Borrow a ring. If your partner wears rings, take one of her rings to your local jewellers and get it measured, it’s tricky to secretly do this but also a pretty accurate method.
Sleeping Beauty.If your partner is heavy sleeper, you’re in luck! While she blissfully slumbers, wrap a piece of paper or string around her ring finger to get the size.
Trace it.When you get a chance take one of her rings and place it on a paper, draw a circle on inside of the ring and you’ve got her ring size. Pretty simple.
The average finger sizeis a 6 to 6.5 for women, and 9 to 10 for men. When no other information is available to you, selecting one of these sizes is your best choice.
Our dominant hands are generally slightly larger – make sure you measure for her left!
Rings with wider bands will fit a bit tighter. If you plan to measure one of her rings, try to measure one with a similar width as the ring you want to purchase.
If it comes down to guessing, err on the large side. You want the ring to be able to slip onto her finger when you’re proposing!
