Before you begin making online ring purchase, find out your ring size. Pick the finger on which you want to wear your ring. Be sure that your finger is in normal size. Your fingers will shrink a bit in cold weather, and can be enlarged during the hot time.
How to measure finger:
1. Wrap a piece of rope, thread, floss or string of paper around the base of your finger.
2. Mark with a pen the spot where the strip completes the circle or hold it.
3. Measure the strip on a ruler with millimeters from beginning to the marked place.
