# How Tall is Caillou? Full Details on Caillou’s Height

## How Tall is Caillou?

The question about Caillou’s height all started when a Twitter user did a Google search on Caillou’s height. The stunning discovery was that the four-year-old is reportedly 5 feet 11 inches tall. That measures about 180 cm in metric units.

In the hen Caillou’s mother Doris hears him sing the line, “Each day I grow some more,” she responds, “You’re getting to be a big boy!” Maybe Doris is correct; Caillou is already a big guy.

The creators or producers of the show have never disclosed his height. In fact, Google searches no longer even reference this alleged 5 ft 11 height. Results, however, point to news stories and forum discussions regarding his similarly contentious height.

### How Tall are Caillou’s Parents?

As much as Caillou is in the 100th percentile for a four-year-old boy due to his height of 5’11 (180 cm), his parents are at least two times taller than him in the animation.

### Why is Caillou Bald?

Caillou was initially imagined as a tiny infant, which often has very little hair. The addition of hair would have rendered Caillou unrecognizable when it came time to age him for situations more suitable for a two or four-year-old.

Caillou was initially imagined as a nine-month-old infant. He grew hair, and when he was old enough, he was no longer recognizable.

As a result, it was decided that Caillou would never grow hair, and he went on to become well-known for being bald as a young child.

### Why do Parents Hate Caillou so Much?

Parents are quite aware of what it’s like to have a whiny child or be near a cranky child. Not the best, though! However, they also see that the whining usually stops when the child feels better, feeds, or sleeps. And they can take care of that.

Fits and spurts of whining are to be expected; they can deal with them. Caillou, though? That child lives to complain. He complains from the moment he wakes up till the moment he goes to sleep.

Even when he is joyful, he complains. Seeing his face on TV and hearing his voice makes parents want to hide in the bathroom, but they’re not sure if it’s his voice or the perpetual pouty scowl.

### Did Caillou have Cancer? What Evidence is there for it?

The Canadian animated television program Caillou is the inspiration for the Caillou Cancer Theory. One of the biggest ideas is that Caillou had cancer throughout the entire season since the theory is focused on the topic of why Caillou is bald.

The idea that Caillou’s baldness was caused by cancer spread to many news websites. However, this theory was debunked on December 8, 2015, in an article by the Huffington Post. The post was titled ‘Why is Caillou Bald?’

In it, they refuted the claim by stating that Caillou’s baldness results from the fact that Caillou was originally depicted as a small baby in the book series. But as he grew older, the illustrators didn’t want people to not recognize him, so they kept him bald.
