Johnny is 25 and Baby is 17 in the Dirty Dancing film. Context and details:

• The film’s events are set in 1963, and Baby’s narrative places her as a teenager about to start college, while Johnny is depicted as an older, seasoned dance instructor. Based on those cues and corroborating sources, Johnny is generally considered to be 25 and Baby 17 during the story. Some discussions note a common interpretation that Baby could be 17 or 18 depending on how one reads the college plans and the narration, but the most widely cited and supported pairing in contemporary references is 25 for Johnny and 17 for Baby. This aligns with the movie’s age-gap dynamic and the parental concerns shown in the story.
