Norah O’Donnell’s height is commonly reported as 5 feet 7 inches (about 170 cm). There are multiple sources that list this figure, though exact measurements can vary slightly between outlets.

• Common public references: Most bios and profiles show 5'7" (1.70 m).

• Context and caveats: Personal details like height may be listed differently across sites, and only the individual or official representatives would have a certified measurement. When sources differ, the 5'7" figure remains the most consistently cited estimate.

If you need this for a specific purpose (e.g., casting, journalism, or data compilation), I can compile a small, dated snapshot from a few reputable profiles and note any discrepancies.
