How many doors are in the world? This may be difficult to answer, but we can make an approximate calculation. Every door is counted from the entrance to your house to office doors. The most difficult part is that it’s hard to calculate the number of garage and automatic sliding doors. Most people know that the world has a lot of doors, but they are not easy to count.
No one knows how many doors exist in the world. Some say there are 200 billion, while others say that the number is around 600 billion. The debate over how many doors is in the world started during the Industrial Revolution. The old way of counting was very time-consuming, so industrialists began to put wheels on doors to count them. This new counting method was faster, but it did not count doors on buildings with more than one door.
Which is Greater in Number: Doors or Wheels?
In reality, there are 7 billion people around the world, not including children. The calculation of 1 billion people corresponds to the number of people who are capable of entering a door. It is easy to understand that there are two doors for a family with two children. The calculation of how many doors there are in the world is different from the information given by the Guinness Book of World Records and from research conducted by Forbes magazine.
Ryan Nixon, an employee of the tourism industry in New Zealand, asked a question on Twitter on March 5th, 2022. The topic started with a stupid question: What do you think the world contains more doors or wheels? The idea was also discussed by Ryan’s friends at work. One of his colleagues suggested that wheels were not just on cars, but also on watches and other small objects.
The post has become a viral message and governments have made official statements on the issue. Nixon wrote that the debate began when he and his friend argued in a bar after a game of pool. It began with both men arguing that there were more doors than wheels, claiming that every door opens and closes. The idea of a revolving door also came into play at some point, but they agreed that this suggests the value of wheels.
Doors vs. Wheels Debate on social media
The wheel vs. door argument is not new. There are two groups: Those who support the wheel and those who support the door. According to Baidu, the largest search engine in China, the number of cars in China sold in February reached 1.78 million. Total sales in February amounted to 444 billion yuan, 4.9% higher than the same period last year. It can be seen that the wheels will soon replace doors, which will cool down the dispute over how many doors are in the world.

The debate of doors versus wheels has been around for many years. The debate comes from the fact that there are many objects with both doors and wheels or objects that has one or the other. Despite this, social media and TikTok users have come up with many suggestions about how to find the answer to “How Many Doors Are in the World Total 2022.
How Many Doors Are There in The World in Total?
You may wonder how many doors are there in the world in total. Nobody can calculate the exact number of doors or wheels on earth. But it doesn’t mean we can’t make educated approximations about the number of doors. For example, an expert mathematician estimated that the total number of doors in the world is around 42 billion. The mathematician calculated the total number of doors because the worlds popular is roughly 7 billion.
If we take the average number of doors per household (2.54) and multiply it by the total number of households in the world, then we can expect that in total there are 126 billion doors in the world. Since each house has to have at least 2 doors, 126 billion multiplied by two equals 255 billion, the global number of doors.
Conclusion
Taking into account the fact that many houses have more than two doors, we can easily assume that there are probably a lot more doors than 255 billion worldwide – somewhere between 300 and 350 billion. We can do a similar thing with wheels and get an approximative value for their number. On average, every car has 4 wheels, every truck has 6 wheels, every bus has 8 wheels, every motorbike has 2 wheels and every bicycle has 1 wheel.
In the US alone, a country home to 350 million people, there are approximately 50 billion doors. This means that per capita, the US has 47 doors. How is that possible? Well, we have a lot of places where there is more than one door. For example, every family has at least one front door that leads to the outside world/public. And then we have garage doors. And backyard doors. Indoor doors too.
