Field notes
The tool calibrates the display before asking users to match a ring or measure a marked strip, using either a standard card edge or a physical ruler as the reference. Its workflow includes locking a first reading, repeating the measurement, and checking agreement before presenting a result. The page also supports direct circumference entry and links to a printable sizer, size chart, converter, and methodology material.
