Finding your ring size is hard. These calibration rings let you try on real sizes at home, so you know exactly what fits your finger. Each ring steps up by half a millimeter, from 16mm all the way to 22mm. You try them on, find the one that sits just right, and now you have your true size.

Print these rings on your 3D printer. A photopolymer printer gives you the sharpest, most accurate sizing. Once printed, slide each ring on your finger one at a time. The ring that fits snug without spinning is your size. Write down that number, then order rings that match it with full confidence.
