Summary
The ages of the characters in Big Mouth are intentionally kept vague, allowing them to represent a relatable caricature of adolescence.
Judd, Nick's older brother, is estimated to be somewhere between the ages of 18 and 21 due to indicators like driving and buying alcohol.
Leah, Nick's sister, falls in between Judd and Nick in terms of age, around 16 or 17. The age gap between the siblings is exaggerated for comedic purposes.
While the main appeal of Big Mouth lies in its portrayal of the awkward age of its main characters, the show has deliberately kept the age of one supporting star a mystery. Big Mouth revolves around the theme of puberty, following a group of anxiety-ridden middle school kids as they navigate the challenging path to adolescence, aided by the Hormone Monsters. Age plays a crucial role in the show, as the main characters yearn for the responsibilities and freedom of adulthood while longing for the simpler times of childhood.
However, Big Mouth does not always provide clear information about the ages of its protagonists. This is partially because the show's cast is meant to be a relatable exaggeration of an entire life stage, eliminating the need to tie them to a specific age. Additionally, since Big Mouth has been running since 2017 and has spanned seven seasons, the creators have intentionally avoided aging up the characters. If the characters aged at a normal rate, they would have already graduated from high school. Instead, in season 7, the kids finally enter high school, adding to the confusion about the ages of characters like Nick's friends and his brother Judd.
Judd Is Around 18 Years Old In Big Mouth
Big Mouth's decision to blur the ages of its characters complicates the understanding of the age gap between Nick and his older brother Judd. Judd, brilliantly portrayed by Jon Daly, is a darkly humorous character who contrasts sharply with the innocent and naive Nick, as well as their relentlessly cheerful and sentimental parents. Similar to The Simpsons, the characters in Big Mouth rarely discuss their ages, which remain relatively consistent throughout each new season. Nevertheless, several enigmatic clues have hinted at Judd's approximate age over the years, from his ability to drive to his behavior.
In an earlier season of Big Mouth, Judd is still attending high school, evident from his father inquiring about his schooling while Nick is in middle school. However, as Nick moves on to high school, Judd has already purchased alcohol and driven a car multiple times. To legally drive in New Jersey, one must be at least 16 years old, and although Judd might have procured alcohol with a fake ID, it is unlikely that a fake ID would be successful if he were significantly younger than 21. Therefore, it can be generally deduced that Judd is somewhere between 18 and 21 years old by the time Big Mouth season 7 rolls around.
How Judd's Age Compares To Leah & Nick In Big Mouth
In Big Mouth, the show's main character is Nick, who is voiced by Nick Kroll. However, Nick's family members, including his brother Judd and sister Leah, also play significant roles. Judd is at least 18 years old, while Leah is younger than him but older than Nick. Throughout the show's seven seasons, Nick is around 14 years old. This means that Leah is likely around 16 or 17 years old during this time. It becomes clear that Nick's sister relies on Judd to buy her alcohol due to her age. Despite being only slightly older than Nick, Judd and Leah are physically bigger and appear more mature. This comedic contrast amplifies Nick's insecurities, emphasizing the differences between him and his older siblings.
