Since you asked for a “Quick Scoop,” here’s a brief, story-style bit of context:

  • Dally is a teenager in the same general age range as the older Greasers, but he’s not the oldest.
  • Sources that break down the characters’ ages for students and readers consistently list him as 17.
  • Some modern discussion and fan-style guides loosely say “around 17–18,” but classroom-focused explanations pin him specifically at 17.
