C++ Reference holds an answer for that. In the end, it relies on the underlying container of std::queue. Its max_size is also the max_size of the queue.

There's a big difference between theoretical maximum as returned by queue::max_size() and actual maximum. You probably only ever really care about the latter, but there's no way to find out until it is too late. It heavily depends on the state of the heap and the virtual memory address space.
