RFC2233 says it this way
For interfaces that operate at 20,000,000 (20 million) bits per
second or less, 32-bit byte and packet counters MUST be used. For
interfaces that operate faster than 20,000,000 bits/second, and
slower than 650,000,000 bits/second, 32-bit packet counters MUST
be used and 64-bit octet counters MUST be used. For interfaces
that operate at 650,000,000 bits/second or faster, 64-bit packet
counters AND 64-bit octet counters MUST be used.
If you need one-size-fits-all I think I'd bump the byte counters to
64 bits but leave the rest at 32.
