How Many Doors in the World
Doors have been an essential part of human civilization for centuries. From ancient times to modern architecture, doors serve as entryways to homes, buildings, and various spaces. They provide security, privacy, and functionality. But have you ever wondered just how many doors there are in the world?
The sheer number of doors in the world is mind-boggling. Every building, whether it’s a house, an office, a school, or a shopping mall, has at least one door. Cities are filled with countless structures, and each of them has multiple doors. When we consider the vast number of buildings in the world, it becomes nearly impossible to estimate the exact number of doors.
According to the World Bank, there were approximately 2.7 billion buildings worldwide in 2019. While it’s challenging to determine the average number of doors per building, we can assume that most buildings have multiple entrances and exits. Even if we consider a conservative estimate of just two doors per building, that would still amount to a staggering 5.4 billion doors worldwide.
