On television, it’s rather rare for an actor to play their exact age, especially when it comes to young characters. For years, we have watched adults well into their 20s (and even 30s!) play teenagers to various degrees of convincing. But it’s probably comforting to know that all of the young characters in the Young Sheldon cast are played by actors who are the same age.
The CBS sitcom, which premiered in 2017 and ends its successful seven-season run in 2024, will find a secondary streaming home on Netflix in November 2023. Just in time for the holidays, the streaming service gives fans of The Big Bang Theory universe a special present in the form of the funny, charming, and very binge-able Sheldon Cooper origin story.
Young Sheldon takes place in the late 1980s and early 1990s as the titular child genius character comes of age in Texas. His family, friends, and community have trouble relating to and understanding his immense intelligence and unique social practices. It’s a must-watch addition to the Big Bang world for fans of the original hit, but it’s also a great standalone series.
If you’re just now discovering the show on Netflix or have been wondering how old Iain Armitage and the rest of the young cast members are, we’re sharing how old they are now, how old they were when the series premiered, and how old they will be when the show ends.
