The Season 3 finale of The Summer I Turned Pretty (“TSITP”) is expected to be around 77 minutes long , i.e., about 1 hour and 17 minutes.

Quick Scoop

  • Several entertainment outlets and fan sites report that the TSITP finale runtime was leaked as 77 minutes via an email shared with influencers who saw the episode early.
  • Fans on Reddit are also discussing the finale as “1hr17min” , treating 77 minutes as the working runtime.
  • Official platforms typically list TSITP episodes as “about an hour,” but Season 3 has already had episodes running over an hour , so an extended finale fits that trend.

In short: current best info says the TSITP Season 3 finale is an extended single episode of roughly 77 minutes , not a 2‑part movie-length ending.

Note: The 77‑minute length comes from leaks and early-event emails, so it’s not a fully confirmed studio runtime , but it’s the figure fans and news sites are using right now.

TL;DR: If you’re planning your watch, set aside about an hour and a quarter for the TSITP finale.
