Episodes of "The Summer I Turned Pretty" (TSITP) vary in length, generally ranging from around 39 to 66 minutes. Some episodes, especially later ones in the season, tend to be longer, with estimates around 70 to 75 minutes for some episodes, while the finale episode might stretch to about 90 minutes, although this has been disputed by the director for Episode 5 (not 90 minutes).

Overall, typical episodes hover around the 45-minute mark with some variation. If you have a specific episode in mind, I can check its exact duration.
