I want to make some minifigure-scale vehicles and devices, but I am wondering what the smallest possible minifigure enclosure might be.
I know minifigures are not perfectly square. Their arms and heads keep them from fitting in a standard 4x1x5 shaped hole while standing upright (not that I would imagine that looking very good in a model). When in recline with the back of their legs connected to studs, they cannot lie totally flat and must lie at a certain angle.
What I would like to know is the practical bounds of a minifigure with NO equipment(hats, parkas, backpacks, ect.):
In a fully upright position
In a fully seated position.
It would also be a bonus if anyone would also give the bounds for a minifigure in these positions but with the maximum amount of equipment.
