Ring Sizing GuidePrint out the Ring Size Chart (PDF) and cut out the measuring box and then wrap it around your finger. It is best to measure your finger in the evening. Do not measure your finger when your hands are cold.
Or cut a strip of paper about ¼" wide and about 3" long. Wrap it around your ring finger comfortably and mark where the strip overlaps. Lay strip flat and measure length and use this chart to convert inches to your ring size. And you can confirm and double-check your size by placing the marked paper strip inside of a ring that already fits your finger well.
