How to Measure Ring Size Without Her Knowing

You can figure out your girlfriend's ring size.

If you're ready to propose to your girlfriend, but you don't want her to know you're ring shopping, you'll need to figure out her ring size on the sly. Don't just guess at your girlfriend's ring size. You want her engagement ring to fit. With a little stealth and a little help you can surprise your wife-to-be with the perfect ring.

Instructions

1. Ask your girlfriend's close friends or her family members about her correct ring size. They may know what size ring she wears because they may have sent her a ring as a birthday gift or they may have tried on rings when shopping together.

2. Measure your girlfriend's finger while she is sleeping. Wrap a small strip of paper around her finger and mark on the paper where the ends meet. Make sure you take into account the size of her knuckle. Take the paper with you to the jeweler's, and he can use it to size her ring.

3. Use one of your girlfriend's current rings to decide on her ring size. Make sure the ring you choose to borrow is one that she wears on her ring finger as other fingers may be a different size. Use a rule to measure the inner diameter (the width across the ring's opening). Take that measurement or the ring to the jeweler to determine the correct size.

4. Engage in a bit of shopping deception. Pretend to be buying a ring for your mother or sister and ask your girlfriend to try the ring on to help you to choose the style. This will give you her ring size.

Tips & Warnings

• Most jewelry stores offer free sizing adjustment on rings, so don't worry if you end up with a ring that is too small or too big. It can be adjusted.

• Rings with thicker frames usually need to be one size larger than normal.
