Finding the correct size ring.
1. If you have a ring that fits the finger your new ring is intended for, one of the easiest ways to find out its size (if you don't know already, of course) is to use the ring size calculator above.
2. If you DON'T already have a ring that fits If this is the first ring you are buying for this particular finger, there is a simple way to measure: Wrap a strip of paper around the finger you are measuring Mark the piece of paper with a pen where it overlaps Measure the distance from the edge of the paper strip to the mark This is the circumference To get the diameter, please divide by Pi (3.14).
3. Remember this calculator is an estimate of the ring size needed. The most precise way to find your ring size is to have a jeweler do it, but you can also easily calculate it at home.
