Print-at-Home Ring Sizer for Small Sizes

How to Use

  1. Print this page at 100% scale — do not use "fit to page" or any scaling option.
  2. Cut a thin strip of paper (about 5mm wide).
  3. Wrap the strip snugly around the base of your finger and mark where it overlaps.
  4. Lay the strip flat against the chart below. The bar it matches is your size.
  5. Measure at the end of the day when fingers are slightly larger for the most accurate result.

Pro Tip

If you are between sizes, size up for wider bands (3mm or more) and size down for thin, delicate bands. Wider bands sit tighter on the finger.
