Jerry’s apartment in Seinfeld seems to be a structural anomaly, as a popular theory reveals that the iconic sitcom location couldn’t exist in real life.

While New York City-set sitcoms have long been criticized for the unrealistic nature of the characters’ apartments, these arguments are typically in terms of how they could actually be afforded

Alongside the fictional Monk’s Cafe, 129 West 81st Street, Apartment 5A has become one of the most iconic locations in sitcom history because the majority of Seinfeld took place in Jerry’s apartment.

Seinfeld typically only shows Jerry’s living room and kitchen, but during the rare moments that a scene takes the characters through the hallway, the layout of the apartment contradicts itself.

While the physical impossibility of Jerry’s apartment makes Seinfeld’s hallway scenes less realistic, it doesn’t necessarily make the show any less believable.

Additionally, Seinfeld’s apartment layout went through numerous changes throughout the sitcom’s nine seasons

In earlier hallway shots from Seinfeld season 2, the hallway is long and seems to reveal that Jerry’s kitchen would be far too wide to actually exist.

However, this still doesn’t solve the realism of Jerry’s apartment, as the extruding kitchen and angled doorway still have no explanation within Seinfeld’s universe.
