A new debate has sparked on the infamous Tiktok: are there more doors or wheels on the planet? Millions of people are in on it, with a fairly even split between the two options. The simple answer is: we really don’t know.
It all started with Ryan Nixon and his group of friends sparking a seemingly simple debate that quickly turned into something larger – are there more doors, or wheels on this earth? Billions of people are asking themselves this question, trying to figure out the answer. On the original Tweet, 43.6% of people voted doors, while 56.4% voted wheels.

Now, there is no exact statement of what qualifies as a door in this debate, but we can assume it is anything with 2 hinges that a person/thing can go through. Easy right? Wrong. Of course you have cabinets, car doors, doors on dollhouses, doors in houses, doors on toy cars etc. There is usually at least 10 or more full-size doors in one given house, and with billions of people living in the world there must be billions of homes. In short, at the very least there’s 10 billion doors on our planet, and that’s not including any other kinds. Because there is no exact definition of what defines a door in this question, a person could argue a lot of different things making the answer increasingly harder to find.
On the other hand, wheels are absolutely everywhere. There are 4+ on cars and trucks alone and when one takes into account of just how many places hold wheels, it is easy to see that wheels is an easy guess. LEGO and HotWheels are the leading wheel makers of the world, with LEGO producing 318 millions wheels per year HotWheels having one toy car sold every eight seconds, there are also billions of wheels in the world. This doesn’t even take into account all of the wheels in tracks for drawers, sliding doors, and windows, or the wheels on pulley systems and in complex mechanical systems.
There truly is no way of telling which is greater in amount: doors or wheels? The question is left to you.
