The only things you can really rely on are
  • sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <= sizeof(long long)
  • sizeof(short) >= 2
  • sizeof(int) >= 2
  • sizeof(long) >= 4

in MSVC short is 2 bytes, int and long are 4 bytes. Normally I would only use short where space was a primium. Int is useful as it is supposed to be the most efficient size of integer for the platform in use.

true use short if you are writing portable code and space saving is important. On most platforms I have used (all actually) short is 2 bytes, long is 4 bytes and int varies between the 2.
