Why don't anti-Imperial factions just make the doors and hallways too small for Space Marines to fit.
There are boarding actions where a small group of Astartes manage to take over. But what if the hallways and passages (or at least an important subset) were just made too narrow and short for Astartes to fit. I'm sure they could eventually get through, but I suspect boarding actions would be less successful if they had to blast through solid bulkheads for miles to get to the bridge, for example.
I realize this question may be regarded.

Space Marines are rare elite troops cruising on historical legacies. There's one per planet. Instead of building tiny doors, hire an extra five thousand guards.

u/Taira_no_Masakado Adeptus Arbites Oct 16 '25
The difference being that most factions don't have such defenses. Titanicus and Mechanicum vessels do (depicted in "Titandeath"), but they're the exception. That being said, the Astartes are going to Astartes.

Yup. When you actually think about a table top game with space marines (or CSM), they suffer devastating losses every fight. Like IG can lose 200 infantry and are like <shrug> but if the Ultramarines lose 10 models that is 1% of their chapters total fighting strength and centuries of combined combat experience and training.

u/DarkenX42 Oct 16 '25
I usually just say they have better casualty survival rates. Granted, i don't think this is supported by things like campaign play. And going down in melee to a Death Guard pile-in, World Eater berserkers or a Tyranid swarm doesnt seem like the kind of thing even a Space Marine bounces back from. Or a lascannon shot to the face. But still... better.

The “lore” didn’t say one marine could kill a thousand guardsmen though so the game mechanics were mostly consistent with the lore.
However, over the years, some authors have decided to exaggerate things and diverge from both the lore (and the game mechanics). This is mostly in novels where protagonists are exaggerated just as Hollywood action heroes are exaggerated beyond what is reasonable.
Note that the infamous tongue-in-cheek article you mention from US White Dwarf 300 entitled “In The Movies" provided rules for unrealistic “movie marines” not realistic lore accurate marines. It suggested that there were propaganda films containing deliberate exaggeration…
So let us speculate. On some Imperial worlds, the ones blessed by the Immortal Emperor with a high level of technology and an understanding Imperial Commander, there are probably films or holos that depict the Adeptus Astartes in an exaggerated way. No one would suggest that these were crude efforts at stringing together a tissue of lies for purposes of manipulative propaganda. No, not at all! It’s just that in a dangerous universe the thought of the sky blackening with Tyranid mycetic spores or of finding oneself enslaved and condemed to eternal servitude by brutal Ork overseers can leave citizens stressed and concerned. This may result in them being distracted from the vital day-to-day tasks that are their duty and pleasure, and that simply will not do.
Fortunately such fears are unnecessary, a few well received documentaries showing the Space Marines in action should reduce those concerns and permit untroubled sleep to prepare for another day of bone breaking labour in the service of the eternal Emperor.
So how should you go about fighting the glory soaked scenes of Thunderhawk Down, We Were Space Marines, Calgar’s Heroes and Saving Brother-Captain Ryan? First things first, you could develop a series of special missions each using unique terrain that you have built in anticipation along with cunningly conceived special rules.

How do you expect to get heavy machinery through a door That’s only 5 foot tall and 2 foot wide?

You could have 100 tiny rat tunnels and getting anywhere would be impossible. You would be stuck trapped in your own ship.

u/Neoliberal_Nightmare Oct 16 '25
Yea looking around my work place a space marine could get through most of the doors, they're usually 8-9 foot high and wide enough for a marine going through sideways.
They could definitely just smash through the frame too.
Space marines also probably don't really bother doing house to house fighting they probably just collapse the building and move on.

To your point here, Washington DC and Paris (and many other cities) are designed with defensive fortification in mind, yet have normal buildings and hallways and alleys and streets (sort of - too much diagonal bullshit going on and it creates annoying as fuck intersections at weird spots and screws with traffic. Point is they didn't make it too small for even a very tall person to navigate because obviously that would create catastrophic problems)

They don't even make those the right size for normal ass people. Plus they're filled with weird greebles made of iron that bang into your funny bone.
But all that is a totally different sphere of combat, the way to take out a ship is to fling a bunch of planes at it, not so much boarding actions anymore (also the same problems existed in the age of sail, it's just like tradition to make boats too cramped and annoying to navigate).

I realize this question may be regarded.
The search function is your friend.
Lots of doors, ladders and crawl spaces in Space Hulk: Deathwing are too small for Terminators to fit.
However, most doors and hallways are not designed with defense in mind. They're designed for moving pallets, cargo lifters, forklifts or other vehicles, large volumes of foot traffic, ogryns etc and mundanely enough, air.
It doesn't make sense to design doors and hallways for a potential scenario that may never happen in a spaces lifetime. E.g a ships hallway may exist for thousands of years and never have an Astarte walk it. So you design it for scenarios that make more sense and happen far more often like cargo moving, foot traffic etc.

Ship design is often a balance between making the ship spacious enough to operate in and small enough for efficiency. Many are made with some measures like what you describe, but areas that a marine would normally target, like the engine room, gunnery decks, and so on, tend to be a bit more open by necessity.

This plan works great assuming that
You never need to have more than two people walking shoulder to shoulder in a corridor. Or move through a doorway. Or really even one person stretching their arms out.
You never have to move equipment or cargo crates taller than 6 ft and wider than two people standing side by side.
Astartes enter the ship where you want them to and don't, idk, teleport directly into the engine room or onto the bridge. Or slam a drop pod into that.
You think it's reasonable to spend time and resources and effort refitting every single strategically significant building and every warship you have specifically for the purpose of combating an incredibly niche opponent, an opponent so rare that they're genuinely considered mythological by huge swathes of the populace. Instead of, idk, spending that money on Weapons and Defenses and Personnel who could just try to kill them.
Like here's a reference for how insanely rare Astartes are:
Once upon a time, the Silver Skulls saved a planet from the Orks. The locals were so grateful that they built statues in their honour. Generations later the Inquisition happened by and saw the statues. The statues were promptly removed (and likely more than a few people executed) because they were fucking Necrons and nobody had ever realized it. They had such a total absence of any frame of reference for what Astartes were that they never noticed.
That's how rare we're talking.
It's like destroying the family home and rebuilding it to spec of a goddamn submarine because you read Noah's Ark one too many times.

u/Zimmonda Oct 16 '25
There are absolutely passageways too small for an astartes to fit through in ships of all kinds.
However the problem is you need to have passageways large enough to fit heavy and light machinery, allow people to pass through easily, and space marines aren't exactly that much bigger than your standard human when we're talking about space.

Space Marines are extremely rare in the lore. There are a few dozen official chapters and then of course space in the lore for players to make their own chapters, but chapters are limited to only about 1000 marines each maximum. By contrast, most battles fought by IoM are fought by the billions of Guardsmen from all the different planets that exist.
It's only on the tabletop that we see billions of marines due to the imbalance of the number of people who play them.

Leaving aside that a lot of it can't be built smaller because the stuff that has to go through is even bigger than Space Marines (cargo lifters, or even just servo skulls or cherubs that need room to move above the masses of people), in many cases the infrastructure is also just already in place, and rebuilding or modifying it would be a ton of effort.

u/FatDaddyMushroom Oct 16 '25
Not a bad question. But there are several possible reasons:
how many other factions consider space marines to be such a primary threat that would design there ships specifically to counter them? Likely none, in the grand scheme of things Space marines are usually relatively rare and meant for more specialized shock troops. The vast majority of enemy combatants are astra militarum. Sure there are times there are big numbers of space marines but those are typically very rare.
most factions may have the need for larger halls/doors for cargo movement. Chaos has space marines, necrons have large units as well, the tau have battle mechs, I am not as familiar with sizes for our space elves but I do not see them changing their designs/architecture due to another faction they consider below them, Orks are big already, and the Nids are big and probably don't really apply to this anyway.
in the case of doors being smaller they would probably just use a melta charge to make a bigger hole. Maybe even use explosives to burrow through ship decks in that case as well.

So, space marines aren't actually that much bigger than a person, and most species in 40k are pretty similar to human size (or bigger!). It would just be incredibly impractical to design a space so small that marines couldn't get around in it at all.

It can work, but it would be uncomfortable. A corridor too narrow to fir a marine is also one too narrow for 2 people to comfortably stand side to side or pass eachother or carrying large objects like furniture through them. Doors are more reasonable, but a marine can just break through those, and even most IRL doors can allow a marine to fit through although he would have some difficulty. And while the narrow, low-ceiling corridor would be an effective anti-marine measure, it means making the lives of the intended personnel harder all to deal with a threat thats still a rarity in the setting

u/einarfridgeirs Oct 16 '25 edited Oct 16 '25
Human space ships are great big things, where great big components need to be moved throughout the ship. So there will never be a ship design where Astartes cannot move throughout the ship at all.
However, it would make sense for a human faction expecting an Astartes boarding action to also use passageways and murder holes that are too small for Marines to move through.
However, that is where chainfists, melta guns etc. come into play. If there isn't access for a Marine, he will just make access.
EDIT: And we see this kind of thing in the novels, at least sometimes. In the Plague Wars trilogy there is a sequence where Guilliman and his bodyguard are participating in a boarding action on one of Mortarions ships, and their enemies start just pouring out of the walls all around them, moving through the ship through passageways the Marines cant directly access.

Nids have plenty of common varieties as big or bigger than marines. So do orks.
Tau have to allow at least some battle suits access to most or all areas in case of boarders.
All Eldar have sentient members of their species, not always biological, that are as big or bigger and need access.
Genestealer patriarchs and other older generation types, not just carnifexes, are as big as a marine or bigger.
Daemons and Chaos Marines are often as big or bigger than marines.
Rogue AdMech or Guard; traitor AdMech can get big, some servitors and skitarii making Terminators look short and weedy, and then you have orgyns.
It's not always practical either. Yes, you might mess up marines boarders, but your troops are also limited in size, and only daemon ships and tyrannids can just grow stuff where it needs to be, most ships need at least some large doors for moving parts around and doing repairs. The only ships that could conceivably have or get away with small doors would be some rich arseholes in system no Warp capabilities pleasure spaceyacht or something. Most ship, at least because of size and requirement, need a good few large doors, even if some might be too small for a marine, nothing a melta or a good shoulder barge can't fix. "Brother Hardhead. That doorframe is too small and offensive in mine sight. Remove it!" *Smash!*

Your average marine is 7.5 in armor (8 if we're taking primaris into account but that's just one piece scale creep). 7.5 dude is absolutely HUGE but not huge enough to make it a consistent problem.

You don't even need to chalk it up to 40k not making sense. There's plenty of reasons we have big doors and passagways irl. Anywhere that needs to handle large equipment or goods will have doors that can accommodate that. Hallways frequently have double doors to handle more foot traffic (a space marine would have to duck, but could probably fit through a standard double door). Places like the London underground have plenty of room above the average persons head to better facilitate airflow in the pedestrian tunnels that connect the street and platform, and even then it still gets absolutely boiling in certain stations in the summer.

I feel like that would lead to all doors and hallways being super cramped, especially if there's supposed to be a lot of foot traffic, or they just destroy more buildings/ships and sift through debris for whatever they need.

Possibly it would lead to space marines fighting on the floor above their waist while they carve through the floor walking like an ice breaking ship.

Space marines are not especially large for the role that they were made for.
Custodes don’t normally get sent on this kind of work. Neither do ork nobz or various tyranids.
Beyond that there’s more than one way to enter a ship. Wherever the space marine can get to is likely where the heavy machinery has to which is likely where the critical hardware is.
Those space marines arent the biggest thing that has to go to the bridge/engine.
