• Font design, shaping engine, hinting, variable axes, fallback fonts, ligatures, language, display density, and browser rounding can change rendered text measurements.
• Millimeters must be at least 0.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Measure the final shaped text in the target renderer and test the actual fonts, languages, viewport sizes, and accessibility settings used in production.
