Sizing warning

Returned string.

• Nominal sizes vary by manufacturer, region, model, material, intended fit, measurement method, and production tolerance, so the same label can describe different dimensions.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Prefer the current manufacturer chart or governing standard, verify critical dimensions directly, and use a fitting sample or qualified professional when safety or fit is consequential.
