I don't know from "the standard", but, K&R said that
an "int" could be whatever size was most convenient for the processor, 
BUT, that an "int" could not be shorter than a "short", nor longer than a 

Several of the early MS-DOS C compilers used a 16 bit "int" (defaulting to 
2's complement signed), with an 8 bit "char", 8 bit "short" (although 
sometimes 16 bit), and a 32 bit "long" (defaulting to 2's complement 
signed).  Some later compilers made "int" 32 bit.
