Usually where the top of the walls finish.

amount of lifting surface against weight? eventually the air's just too thin.
Thrust enters as well: if you have more thrust you can have less lifting surface. But thrust should drop with altitude. Yet drag and lift should drop in direct proportion to one another as the air thins. Not sure quite how that works out. But it should be the combination of all those anyway.

Lift - weight ratio, when you cant generate any more lift to overcome the weight of the aircraft. This will depend on thrust and wing aspect ratio. Rockets use thrust instead of wing lift and so can reach space

One or other of two things; when the air is too thin to give enough lift or when it is too thin to support fuel combustion, whichever happens first.

lift/weight/power- but these can also be change by type of power and type of aerofoil section being used,type of fuel can also be brought into the equation.

With most, when your engine quits from lack of air.
