Its depends upon the complier but generally int size is 2 bytes.
We can use modifier also for enhancing the size of int as given below:
There are two modifier for INT date type
1. unsigned (2 bytes)
2. long (4 bytes)
unsigned int x; unsigned x; (These both statements are same in C language and size is 2 bytes)
Becasue INT is by default data type in C language.
long int x; long x; (These both statements are same in C language and size is 4 bytes)

Size of int or any data type depends on compiler. You can use sizeof() operator to determine the size of data type. Better to use sizeof() operator to dynamically calculate size of data type. For example while allocating memory for a integer array.
int* ptrArray = (int*)malloc(10 * sizeof(int));
