Method A - Measuring Your Finger
- Find a piece of non-stretchy string about 6" long, or a strip of paper about 6" long and 1/4" wide.
- Wrap it snugly around the base of your finger.
- Using a pen, mark the point on the string or paper where it overlaps, forming a complete circle.
- Compare the length of the string or paper to the lines on the paper below to determine your ring size.
- Note: If you are between sizes, order the larger size.
Tips for Measuring your Ring Size
- Confirm the printed paper size with a ruler.
- Measure your finger in warm temperatures at the end of the day.
- Pull tightly. The sizer must fit snugly to produce an accurate size.
Tips for Buying a Surprise Ring
- Ask your intended recipient’s mother or friend if they know his/her finger size.
- Borrow one of your partner's rings (from the correct finger) and use the Ring Sizer PDF to determine its size.
