Honestly, until we have confirmation that Qrow turned himself into a crow, I wouldn't go smaller than a third of his actual size. It's still enough of a gap that changing size suddenly in battle will still give him an element of surprise, but it's not beyond the realms of the possible size of a human being.

After we have the confirmation...I still wouldn't go smaller than an adolescant housecat.

For growing bigger, I'd suggest keeping it to double his size for now. That still makes the user a giant, really, but doesn't make it crazy.

I may be being a bit conservative on those sizes, but I think they offer a really good limit on the semblance so he can't just crawl up someone's nose and damage their important internal workings.
