Frodo was 50 years old when he left the Shire to begin his journey with the One Ring.
Details about Frodo's Age When Leaving the Shire
- In the books, Frodo shares a birthday with Bilbo. When Bilbo left the Shire on his 111th birthday, Frodo was 33, which is the hobbit coming-of-age age.
- Frodo waited about 17 years after Bilbo left, making him 50 years old when he finally left the Shire on his quest to destroy the Ring.
- This 50 years age contrasts with the film adaptation, where he appears much younger, especially since Elijah Wood, who played Frodo, was in his late teens or early twenties during filming.
- Hobbits live longer than humans, so being 50 is more like a young adult in human terms.
