The question of the extent of the atmosphere makes me think of the unusually large insects of the Permian, and an alternate history of Earth where a denser atmosphere with a higher partial pressure of oxygen allowed larger insects, and in which the end-Permian extinction was due to Earth losing 90% or so of its atmosphere in some hilariously unlikely catastrophe.

It very belatedly occurs to me gravity could also be an issue.

This is clearly a "physics, shmysics" sort of setting.

In fact, if all of Earth's dimensions are multiplied by 10, then presumably so is the radius...and surface gravity, given constant density, scales linearly with the radius. Oops.

I don't think this is really any kind of spoiler, by the way, but I'll ROT13 just in case:

But see The Surface-Gravity Plateau. (Multiplying everything by 10 gets you past the plateau, though, if I'm reading correctly.)
