It is most common to use 4 bytes to store an integer value, even if the full range will not be used. There is no problem putting a 16-bit value into a 32-bit field. The only case where this is not true is when memory is extremely limited and you need to pack as much into every word as possible. Do be aware that most structures are word- aligned, so to actually save memory you must have several adjacent elements in the structure which can be combined into one word. Don
