Printable Ring Sizer
Print at 100% scale — turn off 'fit to page' — or the measurement will be wrong.
Place a ring you already own over the circles until the inside edge lines up. Or cut out the paper strip, wrap it around your finger, and read the millimetre mark.
Match the inside of your ring to a circle.
