The “Caillou is 5 feet 11 inches tall” claim went viral in 2021 after a Twitter user posted a Google snippet of it. Show creators have never officially confirmed a height — the 5’11” figure is a meme, not canon. Caillou is a four-year-old, and PBS pulled the show in January 2021 after 22 years on air.
How Tall Is Caillou?

In 2021 a Twitter post showed a Google search snippet listing Caillou’s height as 5 feet 11 inches (180 cm). The internet ran with it. Memes pictured a 4-year-old towering over his parents, mock NBA scouting reports went viral, and the show’s theme song line “each day I grow some more” suddenly read like a horror trailer.
The truth is less exciting:
- The 5’11” number was never confirmed by Caillou’s creators or PBS.
- Google has since removed the answer from its featured snippets.
- In-show, Caillou is canonically four years old and looks proportionate to his parents.
So the honest answer is: there is no official height. The 5’11” figure is a joke that escaped its container.
Caillou’s Family Heights

The same meme spread to Boris and Doris (his parents) and to baby sister Rosie. Reddit threads scaled them up proportionately to roughly 12’9″ — pure fan math. The show treats the family as a normal-sized household.
Why Is Caillou Bald?
The real reason has nothing to do with illness. Caillou first appeared in Hélène Desputeaux’s 1989 picture-book series as a 9-month-old baby with no hair. When the character was aged up to 2, then 4, the artists kept him bald so kids would still recognize him as the same character. Adding hair would have broken his visual identity.
Did Caillou have cancer?
No. The “Caillou Cancer Theory” started as a fan rumor and has been debunked repeatedly, including by a December 2015 Huffington Post explainer. Caillou is bald because of a publishing decision, not a medical condition.
Why Was Caillou Cancelled?
PBS Kids removed Caillou from its lineup on January 5, 2021, after 22 years on the network. The technical reason: PBS’s broadcast license for the show expired and was not renewed. The show is still owned by WildBrain (formerly Cookie Jar/DHX Media) and continues to stream in some regions.
Parent groups celebrated the cancellation. The show drew years of complaints that Caillou modeled whining, tantrums, and demanding behavior — and that kids who watched it tended to copy him. PBS did not cite parent backlash as a reason, but the timing and the celebratory parent reaction were widely covered.
What Happened to the Caillou Voice Actor?
Jaclyn Linetsky, the Canadian actress who voiced Caillou for the first three seasons, died in a minibus crash near Saint-Liboire, Quebec on September 8, 2003. She was 17. The Quebec coroner’s report ruled the crash an accident. Caillou was recast and the series continued for many more seasons.
Is Caillou Good for Kids?
The show was created to teach toddlers about everyday emotions — anxiety, anger, jealousy, kindness — through the eyes of a 4-year-old. Educational reviewers gave it mixed marks: praise for the emotional vocabulary, complaints that Caillou’s behavior often models the wrong response. If you’re considering it for a small kid, watch an episode first and decide whether you want him as a behavior reference.
