How much does a space marine weights, both with and without power armour?
(please refet to source you are using)

According to the Deathwatch core rulebook (page 28), while wearing power armour a Marine weighs between 500-1,000 kilograms, or 1,100-2,200 pounds.

I am not sure if the disparity here is the result of different types of power armours, aka normal vs. terminator, but in Deathwatch standard Astartes power armour weighs 180 kilograms (396 pounds), so a Marine weighing 500 kilograms with standard power armour would weigh 320 kilograms (704 pounds) without it. Assuming the 1,000 kilogram number is talking about normal power armour, that leads to the possibility of a 820 kilogram (1,804 pounds!) Marine, which IMO seems excessive.

Terminator armour is 400 kilograms ftr.

I once read a Sister in full armor is around 200+ kilos, so by ratio and proportion (based on average height - five for the Sister and eight for an Astartes) that would make an Astartes around...320+ kilos.

EDIT: which surprisingly enough, seems to fit with Void_Dragon's statement about an Astartes' weight without armor. Not sure if that means anything, but its somewhat surprising that unarmored Astartes are as heavy as fully-armored Sisters.

Astartes in most sources that aren't Black Library are about seven feet tall on average.

Also... Astartes are super buff men with hyper-dense muscles, extra organs, and even prosthetic bits lodged in their somewhere. Sisters of Battle... Aren't, and probably are not even making up half of that 200 kilograms, if that is indeed how much they weigh in armour.

Or did you mean they are 320 kilos unarmoured?

Edit: Huh, I see you sort of answered me with your edit.

I dunno, I don't find it all that surprising myself. Space Marines are not just tall, beyond that, they are massive, superhuman in proportions, and whatnot.

Ftr, the FFG RPGs, though noting similar effectiveness, do give different weights for Astartes power armour and power armour for humans. IIRC human power armour is 60 kilograms.

I honestly find it hard to believe that Sisters of Battle are averaging three hundred pounds naked, but eh, inconsistent sources lol.

No, the 320+ kilograms I gave was for unarmored Astartes. The basis is 200 kilograms (Sisters in full armor) with an assumed height of 5 feet, against an Astartes (with 'x' kilograms weight without armor) with an assumed height of 8 feet.

So its 200:5 against x:8...by cross multiplication it would be 200/5 multiplied x/8...so, 5x = 1600...320 kilograms. Again, this may not be accurate, seeing as the given involves a Sister's weight in full armor against an Astartes' general weight with assumed height.

Eh, well, I'm not a mass of muscle nor I'm fat and I'm well around 100Kg and 180cm tall, I can well imagine an Astartes being around 300Kg (as they must have the bare minimum body fat -which has about 4x the volume of the same weight worth of muscle- hypertrophied muscles, thicker bones to support that, extra organs, etc...)

Edited 'cause numerical typo

This is off-topic but...LOL at your avatar.

Assuming a base height of 5 feet for Sisters seems a bit ...tiny. I'd imagine the Sisters would want taller ladies, so there's probably a height minimum. I always pictured the Sisters of Battle as sort of battle-hardened Amazons, so I think a height of 6 feet would be a better estimate.

As for Astartes, all those extra organs and bits probably add quite a bit of weight. Don't their bodies have solid bone ribcages?

Dude am I getting this straight - you have 180 cm and 200kg? And you are satisfied...Don't you mean pounds? I'm 184 cm and 87 kg and I think im a little off balance...

Nah, I typoed badly xD I intended to say 100Kg

I just have a bit o' belly but that's all This would be me a week ago

Contrary to popular belief, 40k does not have a canon, so different sources give different impressions about how big people are or how much stuff weighs.

Examples that may be relevant to this thread:

Space Marines according to many BL novels: 8+ feet
Space Marines according to GW: 7 feet

Space Marine armour according to FFG: 180 kg
Space Marine armour according to GW: 110 kg (and often equipped with gravitic dampener to lower the Marine's total weight to that of a normal human)

600-700 pounds wouldn't be unreasonable.

IIRC, Muscle is much denser then other parts of the body. So a space marine's extra muscle would add considerable weight.

Then the Marine has his skeleton. Their skeleton ends up having much in common with ceramic compounds, and because of this they have dietary supplements they must eat.

Simply changing the chemical structure of bone can add significant weight.

Then we have them being 7ft tall and very broad.


I'd lean more towards the 600 pound range unarmored, but 700 pounds would not be unreasonable.

Hmm, thanks a lot;
one thing bgs me though:
I find it hard to imagine a marine weighting 1.5-2times more than his armour, considering how massive the armour is.

Well in the future it’s possible to develop lighter and lighter armor as they are doing now in modern time, especially with ceramics, though I have no clue what the composition of power armor is.

Of course this varies depending on the source as well, but I think GW went with ceramite (sci-fi ceramics with increased durability?) plates on a plasteel frame nailed to a web of fibre bundles.
Right now, I actually think the machinery (the stuff used to pull the bundles, and the backpack reactor to power it) is the heaviest part. How much the armour plates (thickness according to GW: 1 inch) weigh is anyone's guess.

Unpowered armour is difficult to move in even for a Space Marine. I guess that's less due to the weight and more because the bundles grow rigid or something. Being surrounded by what must feel like a brick of cement would seriously sap even an Astartes' strength, as they can't really build up momentum to exert full force but have to "fight" even the first few millimeters they want to move an arm or a leg.

The weights of Astartes Ceramite Power armour according to FFG in Deathwatch: Rites of Battle (all weights in kg);

Mk. I 'Thunder' : 200-250
Mk. II 'Crusade' : 280
Mk. III 'Iron' : 300
Mk. IV 'Maximus' : 220
Mk. V 'Heresy' : 200
Mk. VI 'Corvus' : 170
Mk. VII 'Aquila' : 180
Vk. VIII 'Errrant' : 190

Just thought I'd throw it out there as a point of reference.

So a marine would weight around 800 points in his armor.

Which is the weight Relic gave for the game Space Marine.
