Field notes
Calibration relies on the standardized dimensions shared by bank and ID cards, giving the screen a physical reference before the visitor compares a ring against the circle. The page includes a US 3–13 conversion table with half sizes, UK letters, EU values, inner diameter, and circumference. It also addresses a common failure mode: browser zoom or print-dialog shrinking can invalidate an otherwise precise-looking measurement.
