Wendy Corduroy from Gravity Falls is generally considered to be 15 years old during most of the series. The show’s timeline and fan references also support that she was about 14–15 in the summer setting of the story.

Quick scoop

  • Commonly cited age: 15.
  • Why people get confused: some fans interpret the timeline differently, since the series takes place around summer 2012 and her birthday is often placed in 1997.
  • On-screen impression: she can seem older because of her mature, laid-back personality.
