The Princess Diaries is the gold standard for the "normal kid finds out they are secret royalty" trope, but the version your kid encounters first—the squeaky-clean Disney movies or the snarky, diary-entry books—will completely change their experience of Genovia. While the movies are a safe bet for almost any age, the book series by Meg Cabot is a sharper, more "teen" experience that handles topics like mental health, romance, and family dysfunction with a lot more edge than Julie Andrews ever did.
TL;DR: For a wholesome family night, The Princess Diaries movie is an easy win for ages 7 and up. If you have a middle schooler who likes fast-paced, funny narrators, the original book series is a fantastic literacy hook, though it skews older (11+) due to more mature themes and teenage angst. Both are about to see a massive resurgence as we get closer to the release of Princess Diaries 3.
If you’re looking for a movie that doesn't feel like it’s for babies but still carries a G rating, the 2001 The Princess Diaries is a rare find. It’s the ultimate "ugly duckling" story, even if we all know Anne Hathaway was never actually ugly. The stakes are low-intensity but high-emotion: fitting in at school, dealing with a crush, and deciding whether to accept a crown.
The sequel, The Princess Diaries 2: Royal Engagement, leans harder into the rom-com tropes. It’s less about the "fish out of water" growth and more about the spectacle of being a princess. It’s harmless, fun, and features a mattress-surfing scene that every kid will want to recreate. For the full age-by-age breakdown of similar hits, check out our best movies for kids list.
Meg Cabot’s The Princess Diaries books are written entirely as diary entries. This is a massive win for reluctant readers because the "one more page" pull is real—you aren't reading long, descriptive chapters; you’re reading Mia’s internal monologue.
From a literacy perspective, these books are a workout for the language comprehension strands of the reading rope. Mia is an unreliable narrator; she’s dramatic, she’s often wrong about people’s intentions, and she uses a vocabulary that is surprisingly sophisticated for a "fluffy" series. If your kid is listening to the audiobooks, they are still doing real literacy work—building syntax, vocabulary, and narrative mapping while Mia rants about her cat, Fat Louie.
The biggest thing to know: Book Mia is not Movie Mia.
- The Grandmother: In the movies, Queen Clarisse (Julie Andrews) is firm but loving. In the books, Grandmere is a terrifying, tattooed, chain-smoking socialite who is often the antagonist.
- The Edge: The books deal with Mia’s "not-so-royal" thoughts. She talks about her flat chest, her vegetarianism, her fear of failing algebra, and eventually, as the series progresses into the later volumes, more direct conversations about sex and dating.
- The Vibe: It’s more Mean Girls than Cinderella.
If your kid is moving from the movies to the books, the shift in Grandmere’s personality can be a shock. It’s a great chance to talk about how different creators can take the same idea and turn it into two completely different stories.
The crown is officially coming out of the vault. We know that Anne Hathaway will return as Mia Thermopolis, and after years of "maybe," the project is finally moving forward with Adele Lim set to direct.
Based on where the story left off, the third film will likely follow Mia as a seasoned queen, potentially passing the torch to a new generation. We’re expecting a heavy dose of nostalgia for the parents who grew up with the original, but the script is reportedly being written to land for Gen Alpha. Since it’s still in production, we’ll have to wait to see if it maintains that G-rated Disney magic or if it leans a bit more into the "real world" tone of the later books. Either way, it’s going to be a major cultural moment for anyone who’s ever practiced a "royal wave" in the mirror.
The most famous scene in the movie—and a recurring theme in the books—is the makeover. Mia’s frizzy hair is straightened, her glasses are ditched, and suddenly the world sees her as a princess.
You don't need to ban the trope, but it’s a perfect "do it with them" moment. Watch the scene and ask: "Does Mia actually seem happier after the makeover, or just more stressed?" The movies eventually land on the idea that her character is what matters, but the visual of "straight hair = pretty" is strong. Talking about it openly helps a kid see the "algorithm" of movie tropes so they don't internalize the idea that they need a stylist to be important.
If your kid has finished the movies and the books and wants more of that "extraordinary life/ordinary kid" mix, these are the moves:
- Ella Enchanted: Another Anne Hathaway classic that subverts the princess trope. It’s funnier and weirder than you remember.
- The Selection by Kiera Cass: This is the next logical step for a middle schooler. It’s The Hunger Games meets The Bachelor, but cleaner than that sounds.
- Hilda: If they like the "girl navigating a world she doesn't quite fit into" angle but want more adventure, this is the best show on Netflix.

Q: What age is The Princess Diaries movie appropriate for?
The movies are rated G and are safe for almost any age, but the humor and school dynamics land best for ages 7-12. There is very little to worry about besides some mild "mean girl" behavior and a few very chaste kisses.
Q: Are the Princess Diaries books okay for an 8-year-old?
The first few books are generally fine, but the series "grows up" with Mia. By the later books, the themes of dating and teen rebellion get much heavier. Most intentional parents find the sweet spot for the book series starts around age 11.
Q: Is there a Princess Diaries 3 coming out?
Yes, a third movie is officially in the works with Anne Hathaway returning. It will release in the future, with Adele Lim directing. Expect it to be a bridge between the original fans and a new generation of kids.
Q: How is the book different from the movie?
The biggest difference is the tone. The movie is a wholesome Disney fairy tale; the book is a snarky, realistic look at a 14-year-old girl’s life. The book features a much meaner grandmother and more "edgy" teenage commentary that was scrubbed for the Disney films.
The Princess Diaries is a rare franchise that works as both a "safe" family watch and a genuinely engaging book series. The movies are the entry point, but the books are where the real character development (and literacy practice) happens. Whether you're waiting for the new movie to drop or just starting the first book, it’s a great way to talk about identity, expectations, and why Julie Andrews is a national treasure.
