    Helpful Tips of Finding Accurate Ring Size

    • Measure your ring size at the end of the day. Your finger will be the largest at the end of the day and when the temperature is warm. • Measure finger size few times to avoid an inaccurate reading. If your measurement falls between 2 sizes, choose the larger size. • Your ring should fit your finger comfortably, loose enough to slide over your knuckle, but will not fall off.

    The formulae commonly used for calculating ring sizes are included below.

    1. Measure your wrist with a flexible tape measurements or a thin strip of paper just below the wrist bone(below the bone is after your wrist bone, towards your hands). Wrap the tape or paper around the cuff of your wrist. 2. Get the circumference of the wrist. If you are using a strip of paper, mark the spot where the paper meets the other end. Measure the distance between the spot with a ruler. 3. Add one-half inch to the measurement for babies and toddlers and add one inch for teens and adults.
