Every time I’ve seen this come up, it turns into a kind of coastline problem. The closer you look at everything we’ve built you just start finding more and more doors and just as you think it must be the winner you start seeing all the wheels that go along with them (or vice versa).
It’s impossible to know which one wins without very clear (and limiting) definitions of “door” and “wheel”. Those definitions would have to be equally restrictive to both “doors” and “wheels” or else the limitations decide, not the world we’ve built around us. I posit that anyone claiming to have an answer have made up their own limits of what “counts” and those limitations are likely not equally balanced.
If ball, needle, roller bearings count as wheels doors lose by a loooooot
What about ball-peen hammers?
What about Deez nutz
Dem bitches warny
Every door that is opened by a hinge has AT LEAST one wheel associated with it 🤷
Wheels win 😈
I don’t think that is accurate, the majority of door hinges I am aware of have what I would call an axle, but no wheel.
There are definitely some doors on wheels though, plus everything with wheels has at least 2 so I think wheels win
I feel like most things with doors have more than one door too, but I guess that depends how granular you get… For example, my kitchen has like 30 doors. But like, that one singular cabinet only has one door…
There are doors and hatches that have no hinges. They lift out.
Are gates doors? Therefore are logic gates doors?
Oh man, what about electrical switches?
Thanks. We’ve only been at it for 20 minutes and this is ending friendships in my group chat.
Im going to chime in here and say we expand the definition of wheels to include doors and the definition of doors to include wheels.
Problem solved.

In the future, all doors are wheels.

I fucking love wheels vs doors. My entire workplace is about to start throwing chairs. Thank you OP.
People are getting way to technical about it
Human made doors vs human made wheels
Balls don’t count as wheels
I would say you need an actual door so the doorway between your living room and hallway doesn’t count. That’s a doorway, not a door
The issue is, what counts as a wheel?
My car engine has some round shit that spins for belts on it, are those wheels? I would say, for fun, no. It has to be a wheel… used for moving the object around, gears and shit don’t count
I still think wheels win because there are lots of toy cars in the world
A gear is called a tandwiel in dutch. Which translates to teeth wheel.
So those are wheels and they are everywhere.
Fair, but I think when somebody says “wheel”, they’re talking about the things on cars or bikes or chairs or whatever that help it move
Counting gears and such just seems way to technical for a casual debate between friends at a bar
At least, for me. But every friends group is different
It’s called a cogwheel in English
Look, I’m not about to let Dutch tell me what’s a wheel and what isn’t. 😉
Relatedly, I heard somewhere (probably on No Such Thing As A Fish? but maybe also on Lateral) that the manufacturer that produces more tires than any other is Lego.
Toy cars, scooters, bicycles, motorcycles 2:0 real cars are probably a little over 1:1
I think you nailed it
Would a car trunk lid count as a door? My guess would be no. Same with the hood.
What about on a van? My kids get in and out of the back door of our van, but when all the seats are up it’s essentially just a big trunk lid.
Then consider kitchen cabinets. There’s no other word for cabinet doors - they are necessarily doors. Is a trunk lid different from a car door in any ways that a cabinet isn’t different from a house’s front door?
I dunno, I think a lot of those “round shit that spins” are defined as wheels. A pully consists of a wheel and something stretched over it and pulled. A gear is literally a “toothed wheel”. I could see an argument that a typical ball bearing consists of 2 wheels, an inner and outer.
Still though. Doors are everywhere. Cabinets, ovens, microwaves, fridges/freezers, washers and dryers, closets, etc. The trunk and hood of a car, the glove box, center console, the little storage compartments tucked away all over modern SUVs, hell there’s a door hiding the mirror on my driver’s and passenger’s sun shade in my car.
I think I could literally have this conversation back and forth all day. lol
Easily wheels. Every roller bearing in things like drawer slides, sliding closet doors, sliding shower doors, sliding screen or glass doors, etc. are technically a kind of wheel. A single door could have multiple wheels. Garage door segments with multiple wheels as rollers pre segment. Cars, bicycles, scooters, skateboards, motorbikes all have multiple wheels. Wheels aren’t just for locomotion. 18 wheel trucks have only two doors but obviously 18 wheels, not including any hand-trolleys it might have in the back for loading/unloading. Trains have multiple bogies usually with 4 wheels each and two to a car, 8 wheels per car and maybe two to four doors.
But wait, what about an office building full of hundreds of doors? Think of every office chair with multiple wheels. Desk drawers. Office carts. Elevator pulleys, doors, and guides.
Wheels win.
Way more wheels than doors.
All creatures have an anus, and an anus is technically a door. Think how many insects there must be.
an anus is technically a door
Interesting take.
it’s really give and take
"Previous research conducted by various teams confidently concluded that the abudance of wheels present on Earth greatly outnumber the frequency of doors. However, our lab, through novel research conducted by NigelFrobisher, presents the Insect Anus Theorem. In this paper we will explore why insect anuses… "
Can’t beat that technicality, we’re surrounded by assholes.
If a sphincter is a type of door, the body has many of those. Not to mention other biological doors. Doors absolutely win this imho
I come here for these answers
Maybe not anuses, but I can see valves being considered doors. And animals have tons of valves
Appliances have doors. Some.even have multiple, like fridges, dishwashers and tumble driers.
But yeah, I’m still on team wheel
Tumble driers have wheels to rotate the drum on. Some dishwasher racks have plastic wheels for sliding the racks out.
I see your wheel argument but want to add cabinet/closet doors to muddy the waters. My non-representative bathroom has 6 doors and no wheels. Then there are developing countries that often don’t have wheels on their drawers and doors and rely on hinges more.
But they can have cars, motorcycles, mopeds, bicycles, hand carts, carts pulled by animals, and more. Does a doorway need to have a door on it to be a door? I kinda figured it sorta does, and probably in developing countries they might have curtain covers for cabinet doors rather than solid hinged ones. Not sure though.
It really depends on the country I’ve been to latin America and most people there have doors on their cabinets from what I’ve seen. Wood and labor there come pretty cheap. We’d need to get a good idea of an average house in India and China to make an educated guess.
One thing I’m pretty sure about is that there are more wheels being created now than doors.
You have me considering team door
wheel’s by several orders of magnitude
If ball bearings, needle bearings, roller bearings .etc count as wheels it’s possibly many, many orders of magnitude more
I think SciShow did a thing like this for Eyes vs Legs.
It comes down to definition, but if one, but not the other, definition include biological parts then that one wins.
If no biological being has “wheels” but say, a valve, is considered a “door,” then doors will always win.
But again, it comes down to definition.
A valve is not considered a door.
Why not? If the valve has a hinge and closes off a pathway when shut, i don’t see why it shouldn’t be considered a door.
A switch is a type of door for the pixies… and every car has a whole number of those, so doors win
That’s exactly what I mean. What is, and isn’t, a door? What is, and isn’t, a wheel?
Are treads a type of wheel? Are sliding doors, doors? What about a sliding window on a slightly smaller frame? Are rotating doors are doors, but not open doors? Are bearings and rotors wheels? Are gears wheels? Is a log a wheel, and if not, then if you replace a car’s tires with similarly shaped and sized logs then are those wheels?
Is a valve a door? What about a very large, flat shaped valve that looks like a door? Is a swinging door a door or a wooden valve?
If you count toys then it’s definitely wheels. Even if you didn’t it’s still probably wheels. Chairs, strollers, shopping carts, luggage.
Any large multi-room building, like an apartment complex or a hospital or something, would drastically increase the door count. And if we’re talking toys, what about toy houses? Do lego doors count?
Hospital doors have to be out numberer by the stools doctors scoot around on, I think.
Plus hospital beds, medical equipment, supply carts.
But all those medical cabinets have doors too, lockers have tons of doors… It’s a tight race I think.
Wait a minute…. Medical carts have wheels too!!!
Does a double wheel caster count as two wheels or one? Either way, every office chair probably has 5 wheels, 10 if it counts as double.
1 office chair has 5 wheels. Almost every home has at least 1 office chair. And if we look at hospitals then it gets even worse because there are a lot of the beds have wheels.
And then we can go even further. A lot of curtains use rollers which are wheels. So if I just look at my apartment, I probably have 15-20 doors(cabinet doors, etc. but a lot of the normal doors are sliding doors which use wheels) and probably 50-100 wheels. And that is probably undercounting the wheels that are there by a lot.
Yeah, but does that hold up globally? There are 8 billion people out there, plenty without computers or curtains. My guess is wheels only win cause you can also count defunct wheels on landfill bound chairs and things-- is a door still a door if it’s unhinged and scraped?
we getting into quintessence talk now.
Plus all the mechanical components that are technically wheels; gear and cogwheels, flywheels, pulleys, etc.
Cabinets man. Look around in a kitchen or bathroom, every single house in the world has a ton of doors.
Hotels, they’re basically made out of doors (including furniture and appliances). Cruise ships take it to a whole other level.
Commercial lockers. It’s ridiculous how many doors these spaces have.
Wheels probably wins because of the ridiculous amount of toys, but it’s a fight.
deleted by creator
And inside those apartment complexes? Luggage, storage bins, drawers, IKEA daybed couches, modular tables, entertainment centers, desk chairs, and compact pizza-cutting utensils, all with one or more wheels.
Hospital carts, chairs, wheelchairs, medical equipment, pretty much everything has wheels.
Lego wheels vastly outnumber Lego doors though.
Lego is the biggest tire manufacturer in the world.
Yeah but that doesn’t take into account cabinet and interior doors which are never-to-seldom in Lego builds.
But so do lego 18 wheelers.
Also, wheelbarrows, roller skates, one wheels, scooters, trains and roller coasters…
I wasn’t sure when I opened the comments but you have fully convinced me #teamwheels
Wait - are we counting furniture? Because cabinets, wardrobes, refrigerators, etc all have doors. #teamdoor
Some of those also have wheels, 4 usually, while at most having two doors
#teamwheel
I don’t know if this is true, but when I was doing training in the tyre industry, one of the leaders liked to ask, which company, globally, manufactures the most tyres? obvious answers included Michelin and the like. Their answer? Lego. apparently they pump out more rubberized tyres than any other car tyre manufacturer
again, not sure if actually true, but it makes me think there a lot of wheels out there. however, Lego also makes things with doors…
This is a true fact, Lego even has the Guinness world record for the number of tires produced per year.
https://www.guinnessworldrecords.com/world-records/100909-largest-tyre-manufacture-per-annum
I wonder what the rubber volume is like in comparison rather than numerical volume.
The materials are different, but a Lego tire is like 2.5 grams. A car tire is, let’s say, 10kg - some are lighter, others heavier.
Michelin alone produces like 200 million tires a year, Vs Lego’s 300 million, so car tires use more materials by several orders of magnitude, it’s not even close.
Gears. The car’s transmission alone has probably 30 meshed together on its own, not to mention gears are in everything. Bearings too. Is a sphere a wheel? Casters, slide rails with wheel runners, washers, and conveyor belts feel like they deserve a spot as they are round locomotive devices.
Doors also are very rare in nature, but a rock pretty regularly forms the right shape for a wheel.
I might be missing the forest for something that looks like trees, but it feels like there are overwhelmingly more wheels than doors.
Think about how many wheels and doors you have in your place. Every cabinet and oven has a door. Every building is chock full of doors. I feel like most people only have a few wheels around compared to doors.
I have a wheel on my mouse, four bikes, a scooter, roller blades. Are gears wheels? Then a mechanical watch is breaking records
Nope. Not falling for it. NOT FALLING FOR IT.
This leads very quickly down a rabbit hole on what precisely counts as a “door” or a “wheel.”
Okay but… are we counting doorways as doors? Or just doors themselves?
What about revolving doors
Is a doorway a door? Is a defunked door without a doorway (like I just took off my storm door and its propped against my house) still a door?
I say wheels.
Because of Lego.Any pulley or sprocket is arguably a wheel.
What about gears?
Gears are just wheels with teeth. They absolutely count.
Just because they are round doesn’t make them a wheel. Now if we count the individual balls in a ball bearing as wheels then wheels win hands down
They turn on axles, which ball (or needle/roller) bearings do not.
You are correct, even though a great sounds on an axis I still have a hard time thinking of that as a wheel
Isn’t LEGO the largest manufacturer of tires in the world?
Is a rotating ‘door’ actually a wheel because it spins?
is a wheel a sammich?
Searching the definition of a door at 2 am, befire i start checking average production data for home appliances like toaster ovens, air fryers, microwave ovens, etc. Fridges have doors. Doors have doors. Dog doors. A door can have two doors. A dog door and a spyhole door.
Yeah no. Too broad
It gets so much worse than that. Is an electrical switch a door? It’s a straight bit that bridges a gap and rotates on a hinge. How about gears? Do gears count as wheels? They’re round, they spin, and they apply mechanical forces on their perimeter.
You can actually attempt to answer a question like, “are there more dogs or cats?” because dog and cat are relatively specific. You might quibble whatever wolves or lions count, but adding wild animals to the numbers won’t change the math much. But door or wheel? Those are objects much harder to pin down.
Taxonomy is what’s the difference here, but doing taxonomy on “everything” is basically inventing language and conversation
Does a saloon door count as two doors?
Obviously . Does a saloon door, that has its hinges left, only count as a door, though? Two doors?
It’s too late. It’s already a lost cause…
This has broken my brain.
I have 40+ wheels I can think of in my house. Chairs, carts, bikes, shit there’s even one on my mouse. That’s not even counting all the wheels in my massive Lego collection.
But then again… Cabinet doors, microwave, refrigerator, oven… Fuck!
What have you done to me?
Depends on how you count wheels.
A bicycle has two wheels right?
Well, what about the bearings? Those are basically little wheels, should we count those? Now hold up a sec, inside the bearing, there are either balls, or rollers, which actual like little wheels for the bearing to turn on… so maybe a bike has like… Over 40 wheels on it.
Personally, I think I’m going to go with wheels over doors. I can think of a lot of doors that have wheels in them, but I can’t think of that many wheels that have doors in them.
A wheel needs an axle, so the bearings aren’t a separate wheel, but part of the larger wheel. You can have multiple wheels on the same axle, but not on the same plane. It gets more complicated when wheels are attached to eachother like on a truck.
In the same vain, I think doors need atleast a frame and a large sheet of some kind to close it.
Wheels definitely still win by a large amount though, think of all the factories with machines with dozens of wheels in them
A wheel needs an axle, so the bearings aren’t a separate wheel, but part of the larger wheel.
So if you take the wheels off the bicycle, are we no longer counting them as wheels?
Also, bearings have inner and outer races, so technically, the inner race could be considered an axel.
In the same vain, I think doors need atleast a frame and a large sheet of some kind to close it.
I think this definition of “door” is probably too restricted at the same time. When I moved into my house, I had to take some doors off to get the furniture in. The doors are still in the basement. My wife sometimes asks me what we are going to do with the doors in the basement. If someone was down there, they would recognize them as doors that have been removed. By your definition, those doors aren’t doors. As the same time, the lid on a dumpster meets the definition of a door, so maybe the definition you have is too expansive?
The point is, the question is confusing because wheels are doors are concepts that we have, and not strictly defined objects.
Well yeah I think a perfect definition that fits every situation doesn’t exist.
I think if the described item doesn’t fulfil its role at the current moment, it doesn’t count. Otherwise any round object with a hole in the center can be a wheel or any flat sheet could be a door
Upvoting for importance in this debate: You can’t count a wheel twice if it has wheels nested inside of it
I say wheels: trucks, trains, planes, chairs, skateboards, roller skates, toy cars, small cabinets with wheels, bikes, motorcycles, scooters, wheelbarrows etc have more wheels than doors.
But think of all of the buildings that have no wheels and tens or hundreds of doors. And what about cabinets, they unequivocally have doors and only occasionally have wheels
They often have wheels on furniture
I had this thought too, then I realized the office chair I’m sitting in has 5 wheels, and the cabinet with my printer has 4, but my office only has 1 door. Then there is my secret bookcase door, but it has 2 wheels. Counting everything door and wheel in my house comes out pretty even. But doors would win if you count cabinets as doors.
Why wouldn’t you count cabinet doors?
There are many biological things you could easily consider a door, but there are no biological wheels.
Also planes have doors to enclose their wheels. When not in use as well as doors for the passengers and pilots to enter the plane. I think on average there are more airplane doors than airplane wheels.
There absolutely are biological wheels. The ATP synthase molecule has an axle and rotor that spins, and you have ~1 quintillion in your body.
Other than most planes have multiple wheels per gear. And especially so the heavier it gets.
For planes, I’m on the wheels side
That’s a hot take, considering there is a door above every row of seats on a plane for passengers carry-ons, not to mention all the doors for all the stuff the flight attendants have stowed away that has to be able to be closed off. There are SO MANY doors on a commercial plane.
Are those really doors though?
And if so the rollers on the back to help them pivot are wheels…
I don’t know enough about how airline storage door hinges are built to know if I can agree with them having wheels, but most hinges I do know of don’t contain wheels.
Hinges are not wheels
Yeah planes probably have an balance between wheels and doors.
I can see the biological angle I think that’s a bit stupid, if we consider transistors doors then doors win by a giant margin. So I considered the simple definition, like a car door or house doors and same with wheels
Wheels, just because of Lego
Today, almost 50% of all Lego sets contain wheels.
And this is without getting into non-vehicle wheels like flywheels, gearwheels, etc
And electric eels.
No, sorry, I think I got myself confused.
Lots of Lego sets have doors too. I think wheels still probably win, but it’s closer than you think.
Define both. Does a doorway with no door but instead beads or a curtain count? Is a tiny door a door? A cosmetic one? Are spinning and potter’s wheels wheels? Casters on furniture?
I think each string of beads counts as its own door. Hear me out. If you had a double door, you’d count it as two doors, right?
If you were living in a cave and you used an object to block the entrance, that’d be a door, right?
Ergo many objects that together serve as a door just by being in the way each count as separate doors.
But if you had an accordion door you’d only count that as one, so that’s why it’s each string of beads and not each bead.
Are the component parts of a hinge on a door a wheel?
Is a transistor a door? Then doors (and it’s not even close). Otherwise wheels because gears are wheels.
Glad I’m not the only one who thought transistor
I’d classify them more as gates, not doors.
Gates typically contain doors, yes?
Depends, I wouldn’t say one of these has a door:

It does contain multiple gearwheels however…
They are gates.
I’m more likely to count individual bearings in a ball bearing as a wheel than a transistor as a door
Individual ball bearings are definitely wheels.
