What is the maximum allowed stack size for each goroutine in Go?

In Go (Golang), each goroutine has its own stack, which is initially very small — usually around 2 KB. This allows for the efficient creation of thousands of goroutines without significant memory consumption.

A goroutine's stack dynamically expands and contracts as needed. The maximum stack size is not fixed and is limited only by available memory and operating system constraints.

Therefore, it is not possible to specify a specific "maximum size" for a goroutine's stack, as it grows dynamically. This is one of Go's advantages — efficient memory management for concurrent tasks.
