Starcraft's units, while impressive, are still dwarfed by EVE's and even Warhammer's ships in sheer size (and did you know the different battlecruiser models were quite different in size?).
I am not sure if the person compiling the picture 'stole' images (that belong to the original artists and the companies that commissioned them anyway), but his presentation makes comparing things easier.
Biggest one i know of is the excecutor super star destroyer from starwars (darthvaders flagship) at 19.000 meter (19 km) long. Got that one in lego (its awesome) and it has some details listed. crew:280735 carries 144 tie fighters, 50 at-st,s and 24 at-at,s (no clue where they got that info, maybe they just made it up lol)

The Warhammer ships look funny, you can see they are table top minis. Those skull ornaments were probably pretty small IRL, but then some guy decided "mine is thousands of kilometers long!!" and suddenly the skull is as big as the Imperial-I class Star Destroyer^^
The EVE ships look interesting, somewhat organic. I wonder what their story is.

O thx, didnt see that yet,wow this is awesome
I'm not sure if it was retconned later on or if you read wrong but I know for a fact a executor class super star destroyer was 8 KM long, the average star destroyer being only 1.6 KM in length. So it was still substantially larger and had tons more firepower then most other capital ships but it wasn't the biggest.
The biggest SSD (Super Star Destroyer), that I know of was the Eclipse class. I think only one was ever made, it was 17k KM long and with several substantial upgrades over the old SSD kinds, it had shield generators build deep into the hull and better protected, it had 4 gravity well generators build into it, so it could act as a interdictor cruiser and suck ships out of hyperspace. It also had a Death Star esque laser, that ran the length of the ship and fired from the tip at the end, it wasn't the big planet buster laser, but one of the side lasers that feed power into the big one, still it had enough power to cause cataclysmic damage to a planet and/or destroy a any ship know of till then.
Anyway awesome drawing, the size of most of the things in SC2 really makes us humans look insignificantly small and fragile by comparison.
Edit: Nvm, I saw both the Executor and the Eclipse in the top link, 19 KM holy mother of mercy.

The 8 KM figure comes from a poorly-considered Star Wars RPG table, which completely ignored the visual evidence of the films. In the films, it is easy to observe that the length of the Executor to an ordinary ISD was far greater than 1:5. Nonetheless, the 8 KM figure has become something canonical to the Star Wars EU fandom, making its erroneous measurements appear in video games, technical catalogues, and miscellaneous unofficial output.
Then in the late-90's the fansite "Technical Commentaries" explored the issue at length, and came up with the measurement that the evidence provided by the films pointed to a ratio of 1:11, making the SSD by that relation 17.6 KM.
Given the exponential disparities, we can take all the old RPG stats with a grain of salt. According to such stats, an Executor-class ship was only provided with less than half the ground vehicle complement, double the fighter complement, and triple the personnel complement of an ordinary Star Destroyer, whose volume it must exceed by a factor of hundreds.
The obvious conclusion to draw is this: Darth Vader's Star Destroyer which made its debut in the Empire Strikes Back was designed for its visual effect, and aura of domineering size. Its was not designed with nerdometric concerns in mind.
Well Eldar Craftworlds are technically Starships and those are planetoid-sized and are supposed to house at least millions, but they never explicitly state a size because nerds would nitpick everything apart.

There is definitely something wrong with the SC2 comparison, the top part and the lower part don't match. I mean, look at the size of a phoenix and compare it to a marine. It's about half as big.

The starcraft chart uses to different scales. Compare the broodlord to the left of the mothership to the one below it

don't you remember one of those installation missions taking place inside a science vessel? they're clearly really big.
I love those comparisons. there were plenty of mods for ST:Bridge Commander in which you could add ships from other universes...hell, the balance issues were limitless...think a Babylon 5 cruiser without shields firing his 100 weapon batteries on a much smaler ST ship with shields but quantum torpedos....and then a SW:star destroyer enters the battlefield...
I'm curious as to why BW carrier is so much larger than SC2 carrier, unless BW is specifically the gantrithor.
The really big shockers for me were the science vessel, and void ray.
I think where the ultralisk sizes differ is from the cinematic(ultra crushing the siege tank, which is ~3m tall) being considered correct, so you get like a 15m tall ultralisk. In the books an ultra was ~half that height, although I think part of that is ultra's evolving a crest.
Behemoth class BC is the one in the HOTS mission, Minotaur IIRC is the generic SC2 class.

PS. Ringworld is included on the site PS.2 I Agree leave anime and manga out of this.
This is sweet. I wanna also see Durandal, Elsa, Dammerung, and other ships from Xenosaga, as well as the Eldridge from Xenogears. And of course, Spaceball 1.
Oh only now see the dyson sphere. Wonder if this is actually viable, wouldnt it get incredibly hot inside as all radiation stays inside? And how to prevent it from exploding due to the build up of heat? I read about the concept before but when you think about it, it seems kinda impossible no matter how advanced technology is.
There are some anime ships in there on the bottom-right of the Caldari leviathan, though not from a large variety of shows. Legend of the Galactic Heroes occupies most of the anime ships.

It is essentially the size of a solar system. Heat buildup would not be a problem, especially not since it is hypothetically designed to use all the energy for something.
Wow this makes we want to play star wars: empire at war again.
With the Awakening of the rebellion mod, space battles were so epic and huge. And they had almost everything star wars related included as far as I remember. SSD's, casual star destroyers, etc. Awesome times.

Isn't this true for basically everything in Star Wars? When have they ever approached it like typical science fiction, rather than space opera/fantasy?
Well, to be fair SW can get away with going nearly full fantasy with some of its stuff given that the action is set in a different galaxy that evolved in its own way.
The history of SW is also phenomenally long, with something ridiculous along the lines of hyper-drive being first developed 100k years before the battle of Yavin, the force being discovered 35k years before the battle of Yavin. And all along there have been millions of wars that have raged forcing the acceleration of technology or the destruction of some.
The only other comparably long timeline is the Warhammer universe which had its history span 40k years, only 40% of the length of SW and for vast periods of time solar systems where in isolation from each other due to chaos storms, so technological sharing and development was substantially slowed.
Yeah I can imagine technology developing at a rather frightening rate and able to reach nearly absurd levels of sophistication in 100k years.

Not to be nitpicky, but technically the 40k refers to the Imperial calendar. Other species, such as Necrons and Eldar, supposedly had warp-tunneling technology billions of years before homo sapiens even evolved, so the overall history of technological development in the WH40k is considerably longer... however, as you pointed out, it's not precisely a history of technological advancement because much knowledge has been lost to ongoing wars and catastrophes (so that some types of old machinery display mechanisms than the current state of the art cannot even begin to comprehend, so that they are now operated by priests rather than engineers).

Yeah, that is kind of the whole point of the dyson sphere, to completely harvest the energy a star emits.
Also, afaik the general idea of a dyson sphere is usually NOT to have a solid sphere, but a huge amount of smaller orbiting segments which in total absorb all of the energy of the star. Which is a lot more viable, since it is pretty easy to get something to circle a star, while you would need an absurdly strong material to actually build a sphere the size of a solar system because you could only cancel out gravity with centrifugal force on a ring, not a sphere.
but i really wonder how the magog worldship from andromeda would fit in. theoretically, it had the size of an entire solar system. so in theory, it would need to have a diameter which is about 25 times bigger than that of the dyson sphere...

Producing enough steel to build a Death Star (the small one), would take Earths entire production with projected increases for the next 178 years or so.

The issue of having many objects orbiting around all the different great circles of a star is that its a lot harder to get things to orbit some parts of a star than others. There's a reason why all the planets in our solar system orbit on almost the same plane, and if assume that plane to be the approximate "equator of the sun" for purpose of being able to visualise, then when you try to have an object orbit from pole to pole you would find its unlikely it would maintain that orbit. And this is completely ignoring likelihood of collisions with all the crossing orbit paths.

A lot of the stats probably gets provided by the lore, or simply the Dev's provided with them at some point. It must have taken ages to collect them all, and then make or find the models so they can scale it all correctly.

The main reason all the planets are ~ on a plane is that they evolved out of exactly that, a turning flatish disc thingy. It is not fundamentally harder to orbit the sun in any other direction. And of course you would have to plan the whole thing very, very carefully, not only because of collisions, but also because all the objects would interact with each other through gravity which could easily disturb the orbits so some of the satellites collide. Still a lot easier then produce a solid shell.
Amazing. I can't imagine what kind of resources it would take to build something that large. Would be hilarious if someone messes up somewhere and two halves of a 100km ship don't fit together.

Realy think that no such thing will ever exist in this universe. unfortunatly i might add though
There is one reason a a Dyson Sphere might be built. Hiding a star from somebody. This assumes cross galactic wars and being on the losing side.
another issue i see with the dyson sphere are objects from outside colliding with it. there are asteroids entering the inner solar system all the time, many of them being absolutely massive. how would the outer side of the dyson sphere be protected against these impacts?

Pretty sure there's no Dyson sphere in Star Wars...

If you can build a dyson sphere I'm pretty sure protecting yourself from asteroids would be trivial. Plus you used them all to build your dyson sphere anyways.
Where's deep space nine? Okay, it's not quite a ship, per se, but I'm sure it can technically move if necessary and it is fiction, so throw me a bone here

It can move a bit, they moved it towards the wormhole in the first episode. But i doubt you can call that a spaceship.

He must be thinking of Star Trek.
But on a star wars releated note. I found this lol ^__^
White House petition
In late 2012, a petition was submitted to the White House website urging that the United States government build a real Death Star as an economic stimulus and a means to ensure people got back to work again, and wanted its completion by 2016 at the earliest.
The petition gained more than 25,000 signatures, ensuring that an official response be supplied. In early 2013, the proposal was rejected (in a tongue-and-cheek manner), citing that the overall cost of the Death Star's construction would amount to a cost exceeding $852 quadrillion, and would take 833,000 years before it could even be ready for construction due to the rate of steel production.
Another reason for the rejection was also because the Government "did not support blowing up planets

deep space nine is fairly small anyhow compaired to some of thoes ships, roughly 1½ km in diameters

If I remember correctly the independence day mothership was roughly 1/3rd the size of the moon. The deathstar is the size of a moon so I think they win.
The size of a small moon. the ship from independence day also shit out like 20 5mile across smaller ships iirc.
Yeah, and "A small moon" could be something like http://en.wikipedia.org/wiki/Deimos_(moon), which is a lot smaller then a third of our moon Luna, no matter how you measure "a third".
The original site has the death star, the Independence Day mothership, and others compared to our moon Luna. http://www.merzo.net/ There are footnotes explaining how he got the measurements and stuff too.
