Geno Smith is listed at about 6 feet 3 inches tall (roughly 191 cm) in multiple recent profiles. Some sources list him at 6'2" (1.88 m) and others at 6'3" (191 cm), which is not unusual when different outlets measure slightly differently or update bios over time. If you need a definitive figure for a specific team or publication, I can look up the exact profile for that source.
