Odds are, it's an Earth-size planet, at least if Bioware is going by known scientific standards.
Pfft. They don't even do scientific standards in their SF games, so what do you expect? Maybe the DA team would do better - they certainly appear to make a better effort in keeping their lore consistent - but I've lost all respect for the ME team in that regard.
Get much smaller, and the odds of a planet's core solidifying increase, which leads to a loss of a magnetic field, which in turn allows cosmic radiation to strike the surface of a planet unimpeded. Needless to say, that's bad for development of complex life forms.
Get much bigger, and you could wind up with tectonic plates never forming, thus freezing the crust largely into place, preventing the recycling of minerals, metals, water and so on. Mind you, this scale is one that works on the order of tens of millions of years.
Not quite correct. A small planet with a high metal content would work, except that it probably couldn't hold an atmosphere for long. And tectonic plates depend on a planet's age rather than it's size, at least in the size range we're talking about. However, get too big, and you'll have a high helium content in the atmosphere.
Still, the possible range of useful planets goes from about 0.5 Earth masses to about 3.5 Earth masses, with some uncertainty. You don't need magic for a plausible non-Earth-sized planet with a civilization.
