Linked to this post is a Map of Manhattan with a Voidship layered over for visual effect, in this case a Vagabond-class Merchant Trader which accordingly is 2km long, 0.4km abeam approx...

From those dimensions - you get a ship that would span from 1st Avenue to between 7th & 8th Avenues in Length while the Width would stand from 34th Street to 39th Street in aprox measurements...

(Used Google Maps and CoStar.com Map tool)

You get a footprint that covers 1108 Buildings in Manhattan; if dealing in approximations one could get a range from 800 to 1000 Buildings in the one of the most densly populated cities on earth.

The Point:

If I were ever to attempt to use a map as a guide for "in-ship" adventures so to speak - this is where I would get my general baseline when it comes to estimating Real World Dimensions and keeping a charted course sort of like when DMing an extensive dungeon in say D&D for example

That looks a little more like something out of Star Wars than 40k, tbh.

However, more to the point, it's also worth noting that something like the entire aft third of ships are mostly uninhabitable and occupied by the realspace drives/fusion torches, according to the fluff.

Anyways, yeah. These things are bloody huge. Especially since unlike a stretch of city, it's all more or less contiguous vertically occupied as well.

Bit like horizontally extending a skyscraper a massive amount. Or maybe upsizing a massive ship.

Also probably worth doing is blocking out areas of the ship and assigning the various sections a purpose, which will help set the style/theme for how that area of the ship is laid out.

While I'd sort of like to see a full internal map for ships, I think the best that's viable is a general layout and only specific points of interest done in detail, with perhaps some generic examples for each section/style area.

It's a Corellian CR90 Corvette, or blockade runner; Princess Leia is on one at the start of A New Hope.

The scale thing always makes me sad. I remember when Star Destroyers were ONLY 1,000 m long, and the SSD, such as the Executor, was 5 km in length, and Space Station class (though it could move, of course). Then some nerdier than me SW nerds raged that Lucas's movie, of all the places it might've soared or sucked, must've gotten the scales of its models wrong (insert Doc Brown "I'm sorry for the crudity of this model. It's not to scale, but I painted it."), when comparing SDs, SSDs, and the Death Star, all on the same screed, with established numbers (SD 1 km, SSD 5 km, DS 160 km diameter, 1990's Return of the Jedi) and now SSD are like 27 miles long, or something insane. I live in a not so packed area of a largely rural state, and I could still straight drop the Executor, and crush my town, and several others, where they already sit, under it. Dumb.

This all being the case, I still think of 40k as the ridiculous end of the ship size scale. The biggest ships in SW used to be 5 km, Babylon 5, in the series of the same name, was 5 miles long, and station-class, Shows like Andromeda placed many of their best ships in the 600m-1300m range, while everything I've always known about 40k places their ships in the ludicrous zone, where things are so big, even "snub fighters" have a crew of 6-12, more people than it took to man the Millennium Falcon , the Outrider , and sometimes the Andromeda Ascendant . it amazes me, sometimes, that more 40k ships don't have interior monorails, "ski lifts", or anything less than site-to-site transporters, since that in 40k would end messy way to often.

I assume 40k capital ships do have internal transport systems. The flagship in one of my campaigns got an upgrade from the Magos in the forge on Damaris, who had worked with a Salamander Forgemaster to perfect Damaris City's transport network (previous Deathwatch campaign in the buildup to a successful defense).

Oh, you mean when WEG made up numbers without looking at the models or movies? Like when Star Destroyers had 50 identical turbolasers or the Nebulan B had an internal hanger bay for 12 tie fighters? Good times

I don't think there's anything that unreasonable about 40k starships, given the scale of other industries we see, or based logic. When constructing vessels in microgravity, there is no technical reason why a ship can be as large as the designer might want, and people are constantly finding ways to make things bigger. Hell, look at our own aircraft carriers - they are of a size that would have been considered fantastically preposterous 200 years ago.

(and yes, I also assume there is a subway like system. It's a floating city after all.)

Since it's 40k, the carriages of the train system are likely pushed by slaves while elevators are powered by chains pulled by more slaves.
