No. It will also depend on database encoding, etc.

I think you should go with smallint, which is exactly 2 bytes. You'll
have 15 bits of storage (16 if you'd want to implement the special case
of minus sign).

IMHO the only smaller field are:
- one byte boolean, but it can only store 1 bit.
- one byte "char" (with quotes), but it is a non standard, integral
type, will cause interface problems and I don't know if it will not be
deprecated some time.
