- Use a piece of string or dental floss and wrap it around the base of your finger.
- Use a pen to mark the point on the string where the end meets.
- Use a millimeter ruler to measure the string.
- Choose the closest measurement to the chart above to find your ring size.

How can I find out the ring size without my significant one knowing 🙂 ?
Here are five ways to figure out the ring size on the sly.
- “Borrow” any jewelry. If they already wear a ring on the ring finger (even if it’s on the right hand), you can use that as a guide..
- Phone a friend. Enlist the best friend, or anyone in the family..
- Hold their hand..
- Put a string on it..
- Give a guess..just the last ditch resort!
