Sort of. Are there any particular C rules saying that

Absolutely.
In K&R C (I don't know from ANSI), it was recommended that an int be
whatever type was easiest to deal with.
A short int could be the same or smaller.
A long int could be the same or larger.
It was explicitly stated that the only given was that the sizeof long int
could not be SMALLER than the size of int, and the sizeof in could not be
smaller than the sizeof short int.
int and unsigned int are often the same size, but that was NOT required.
