Why is stack size limited?

The stack size is limited because you want to be able to run many programs at once: if all 1000 of the programs running on your computer had all asked for 1GB up front (stack is UP FRONT, its allocated at program launch) you would need quite the machine!

How do you define stack size?

The stack size is determined when the thread is created since it needs to occupy contiguous address space. That means that the entire address space for the thread’s stack has to be reserved at the point of creating the thread. If the stack is too small then it can overflow.

Is the stack size fixed?

The maximum stack size is static because that is the definition of “maximum”. Any sort of maximum on anything is a fixed, agreed-upon limiting figure. If it behaves as a spontaneously moving target, it isn’t a maximum. Stacks on virtual-memory operating systems do in fact grow dynamically, up to the maximum.
