theoretically, height is determined by gravity on the planet of origin. physically, an extremely tall person has additional stress on their heart to pump blood against the force of gravity. the strain to keep the body erect is stronger and the strength of bones, muscles, tendons and ligaments, to keep the body erect is more than a person of average height (around 5'9" i think, is the median). the shorter and thinner a person is, the more likely they derive from a planet, moon, space station or space craft, with a high gravity environment (comparatively). the thinner physique allows freer movement as does the shorter stature. in addition, there are several types of gaseous environments that may impact height and density. oxygen is a gas, for example. however, helium is lighter than oxygen.
also theoretically, you would also have to take into account how close to the core of the planetary body, the species formed and thrived. the closer to the center of gravity, the more likely they'll develop lighter, shorter bodies, i should think.edit on 21-10-2011 by undo because: (no reason given)

The universe is ultimatly huge in its neverending size.
Exactly, so an infinite number of possibilities exist as far as what aliens could look like.
Including the representations referred to...

The one thing that bugs me most about how they are depicted is this: if they are so advanced, with the ability to travel huge distances in fantastically technological craft, why do these aliens never wear clothes? Even a pair of undies?
Maybe that's just me...

There's a good reason we are the size we are. Any larger and gravity would crush us. You couldn't have a 20 foot man.
When whales beach they die because gravity pulls all that mass inside them to the ground, crushing their lungs.
I imagine it's the same for alien species.
...unless they develop/evolve on a planet with a different gravity than ours.
I suppose a low-gravity planet could produce larger-than-human intelligent creatures, while a planet with -- say, for example -- 3 times the gravity of Earth could produce intelligent aliens that are built very low to the ground.
However, I'm only talking about creatures evolving on other planets. I'm not addressing the question as to why the reports of visiting aliens almost always tend to describe human-sized aliens. I suppose if someone tends to believe in alien visitation, and if the argument is "why aren't these non-human-sized aliens visiting Earth", then the tall aliens from the planet with lower gravity perhaps don't visit for the reason you specified.

Here is the flaw in your logic:
Universe is huge: check
Planets can be tiny or huge: check
Assumption: ET's can come from any planet size (BUZZZZZ WRONG!)

You've seen ETs in dreams/visions or 'special' trips?
