How To Guess Her Ring Size For A Surprise Proposal

If you've ever wanted to embrace your inner spy and go on a covert mission here is your opportunity. Whether you embrace this challenge as a bit of a thrill ride or if you're a blubbering mess scared to get caught - it's time to get sneaky!

Size Up Her Sister or her Mum

Generally, sisters are about the same size when it comes to their hands. If she doesn't have a sister, you can always revert to her mum. Just ask them. They will know if your special woman has the same size hands as them or not. If they do you're onto a winner. Ask them to go get sized for you or just take them with you when you go shopping. It can also be a good way to get their opinion on what styles your girlfriend likes. They have no doubt talked to her about it in the past.

Best Friend Spy Work

Similar to the sister and mum approach her best friend knows your girlfriend like not many other people in the world. If you can trust her to be casual about it, you could ask her to take your girlfriend shopping for engagement rings and try them on for fun. This is a super sneaky way to get your girlfriend sized up from the inside without suspecting you're the mastermind behind it all. Even if her best friend can't get her professionally sized up she can mentally take note of the rings she liked and a pretty good estimate of her sizing.

Steal a Right Hand Ring

If you can borrow a right hand ring without her realizing it's missing then you're onto something. Just try and know which finger she normally wears it on so the jeweler can estimate the size of her left hand ring finger. Keep in mind if the left hand is not her dominate hand it is most likely slightly smaller than her right hand. If she doesn't wear any rings on her right hand ring finger the jeweler can still have a good guess of what her size will be (even if it's a thumb ring). Just beware you may need a resize to get the perfect fit, but you shouldn't be too far off the right size.

Get Crafty

Alternatively, if you can't steal the ring from the house without her noticing you can employ one of these tactics. A good way to gauge the ring size without taking the ring anywhere is to try the ring on yourself and mark on your finger where it stops. You can then go to your jewelry store and get them to find the sized ring that gets to the same place. If you don't quite trust this method you could always make an impression of the ring by pushing it into some clay or a bar of soap. You can even take the ring and trace the inside perimeter onto a piece of paper. Just remember no matter what you try here, as with the above piece of advice the jeweler will only be estimating the size because she most likely does not wear this ring on her left ring finger.

Sweetest of Dreams

If you want to go for a stealth mission while you're girlfriend is blissfully unaware in the land of nod, you can take a piece of string and wrap it around her finger. This will be hard to explain if you get caught, so make sure she's actually asleep.

Remember, as with all of these above tips it may not be exactly the right size even if you do everything right. Keep in mind that it is generally a lot easier to resize the ring if it is too big rather than too small. Talk with your jeweler before you buy the ring to make sure it is able to be resized, some bands are too intricate to resize and some bands that are thicker will need to be slightly larger. If this

all sounds like too much, you can always ask her what her ring size is. If you've been together for some time it's not like a proposal would be a total surprise anyway.
