Why wait!? Get it RIGHT NOW! Printer and scissors required.
EDIT: After 36 mins, to be honest, I only just read the PDF file that you can download for free. You don't actually need a scissors, printer or finger. You just load the PDF, zoom in to the right scale, then place a ring that is being worn to match one of the sizes on the PDF, voila, you get the size in less than 2 mins. Great ring sizer, actually.
EDIT2: You don't even need to leave your personal details, just go to the link, and download the PDF. This IS the Ring Sizer of all Ring Sizers.
