Jean Smart is commonly listed as about 5 feet 9 inches to 5 feet 10 inches tall in publicly available profiles. Context and caveats:

• Height listings vary slightly across sources, with several noting 5'9" (175 cm) or 5'10" (178 cm). Different outlets may round or estimate differently based on photos or biographical notes. If you need a precise current figure for a specific purpose, checking a recent official bio or a newly released interview may help, as athletes and actors occasionally provide updates or corrections.
