Printing questions
How do I print the sizer at the correct scale?
In the print dialog, choose "Actual size" or "100%" — never "Fit to page". After printing, measure the verification bar: it must be exactly 100 mm long.
How do I use the printed sizer?
Place a ring that fits on the circles until its inner edge matches one. The size printed under that circle is your size. To measure a finger, use the cut-out paper strip.
Does it work on both A4 and Letter paper?
Yes. Both formats have room for the circles; what matters is printing at 100% and verifying the 100 mm bar.
