How to Measure a Girl's Ring Finger for Size Without Her Knowing

The element of surprise can be crucial in presenting a ring.

Measuring a girl's ring finger without her knowing allows you to surprise her with an engagement ring or a ring for a special occasion. There are several ways to find out someone's ring size secretly, so you can keep the romance and excitement of the occasion alive. Since most jewelers will not take back or exchange rings that have been sized, make sure your measurements are exact.

Things You'll Need

• Permanent marker
• Putty

Instructions

1. Sneak a ring that the girl wears on her ring finger to a jeweler to have it sized. If you do not think you can get away with borrowing a ring for a day, print a ring size chart from a trusted jeweler's website or purchase a ring-sizer stick. Use the chart or stick to measure a ring that the girl wears on her ring finger.

2. Slip a ring that the girl wears onto one of your fingers and mark where the bottom of the ring rests on your finger with a permanent marker. Using a permanent marker will ensure that the mark does not rub or wash off before you get to a jeweler.

3. Make an impression in putty of a ring she wears on her ring finger and take it to a jeweler for measuring.

4. Ask her best friend, mother or sister for her ring-finger size. It is likely that a close female friend or relative will know, as women often share jewelry or shop together.
