Looking for AT-AT Specs?
For whatever reason, major search engines are STILL picking up this page as
though it were more of an AT-AT technical spec page, despite its outdatedness.
I've revamped. And because I hate broken, outdated links, I dont have plans to
remove this page.
Anyway, check here.
(The real new pages are now up!)

AT-AT Specs
Alright, the specs for the AT-AT:
These figures are based entirely off of the AT-AT blueprint in the
Essential Guide to Weapons and Vehicles, and the conversions that I
made by hand using a TI-85 calculator.
A word on minifig scale. Minifig scale isn't an exact science. Minifigs
are terribly disproportionate to real people. But we have to start
somewhere. My starting point was in assuming that your average minifig was
around 42mm tall, and that meant 6 minifig feet tall. It actually works
out almost nicely, since that means 7mm = 1 minifig foot. So a good
approximation is that 1 lego stud is about 1 minifig foot (actually it's
just a bit bigger at 8mm, or 1.14 minifig feet). Anyway, that's the
general conversion rate I try to stick to.
To be overly exact:
1 minifig meter = 2.870734908136 studs = 7.176837270431 plates
1 minifig foot = 0.875 studs = 2.1875 plates
And visa versa:
1 stud = 0.3483428571429 minifig meters = 1.142857142857 minifig feet
1 plate = 0.1393371428554 minifig meters = 0.4571428571429 minifig feet

Other features of the AT-AT
The entire leg has 4 basic joints: the ankle, knee, hip, and "upper hip"
(as I've grown to call it). The upper hip joint is more or less obscured
behind the overhang of the body's sidewall, but it's there-- you can see
it move slightly in the movie as well. Hence, there are 4 "parts" to the
leg: the foot, shin, thigh, and again the "upper thigh".
The body consists of what I'd deem the forward, middle, and rear sections.
All of the body's walls on these areas slope inwards towards the top,
hence, at the bottom of the body, it's wider than at the top. In addition,
the forward and rear sections have even more slopes. The forward section
slopes from the side (gets taller as it progresses from front to back),
and also as seen from the top (it gets wider as it progresses from front
to back). This is also true for the rear section (except back to front),
except for added confusion, the rear wall also slants inward as it goes
up, whereas the front wall is pretty much at a 90 degree angle with the
base of the body.
The body also has hatches or openings (4 on each side)-- two on the
mid-secion (one on the upper level, one larger one on the lower level),
one on the forward section, and one on the rear section. This makes for 8
hatches all together. The upper level hatches are assumedly escape
hatches, whereas the larger lower level hatch is intended for troop
boarding/offloading. In addition to these, the Star Wars Technical
Journal notes another hatch on the rear roof, for speeder bike
access.
The body also houses a large undercarriage, a large drive motor. It's
circular, and is composed of a forward and a rear drive. There is very
little space inbetween the two cylinders, meeting in the middle of the
body. The forward drive is also shorter than the rear drive, only coming
out as far forward as the AT-AT's hip, while the rear drive motor extends
to the very back end of the AT-AT.
The head again has massive sloping issues. It slopes inward, forward, and
upward. Hence, it gets wider as you go down and back, and it gets taller
as you go from front to back. In addition, the front wall to the head is
slanted inwards, just like the back wall of the body.
As for the interior, there's discrepancies. The Incredible Cross
Sections book gives a pretty good feel for layout, but not really a
good floor plan (which I haven't really ever seen). One source supposedly
dictates that the AT-AT's body houses 2 AT-ST's inside! But the only real
guidelines are the shots of the interior of the head from The Empire
Strikes Back and the other "official" stats, of which there seem to be
only two: it has a troop capacity for 40 stormtroopers, and has a small
speeder bike garage, capable of fitting 5 speeder bikes.
