EXPLANATION OF THE FANBOY & CHUM CHUM CHARACTERS’ HEIGHTS
We estimated Fanboy’s height based on the average height of boys his age. Fanboy looks about 11 or 12 years old, and according to CDC, males this age are between 4 feet and 5 inches to 5 feet and 3 inches.
Since Fanboy looks tall for his age, we gave him the upper height limit at 5 feet and 3 inches.
Next, based on Fanboy and Chum Chum’s picture, Chum Chum is about a foot shorter than Fanboy at 4 feet and 3 inches.
Then, we estimated the other characters’ heights based on how they stand beside Fanboy, Chum Chum, and each other.
Kyle looks about the same height as Fanboy at 5 feet and 3 inches from the show stills.
In addition, Yo is about half a foot taller when standing beside Chum Chum at 4 feet and 9 inches.
Next, Lupe is about 3 inches taller than Yo at about 5 feet.
Lastly, Chris Chuggy is about two inches taller than Yo at 4 feet and 11 inches.
EXPLANATION OF THE FANBOY & CHUM CHUM CHARACTERS’ AGES
According to the show trailer, Fanboy and Chum Chum are still students. In addition, Kyle’s Fandom Wiki page said that he was a pre-teen at 11 years old.
From these two pieces of information, we estimated them to be in their last year of grade school or in middle school at about 11 years old.
Since Fanboy, Chum Chum, Kyle, Yo, Lupe, and Chris Chuggy are all peers and were said to be schoolmates, we estimated them to be the same age at 11 years old.
