But since we've only seen Minato using it, we don't know what influences it. If size or weight are what matters, than teleporting Gamabunta should be as hard as Kurama (and edo Tobirama did teleport 2 kuramas simultaneously); if it is the amount of chakra, then teleporting Hashirama should be even harder. Anyways, I think I'm looking too much into it. I think it's a combination of size and mass. Chakra has mass, so that takes care of that.

Minato teleport spammed a lot without showing fatigue, so even without Kurama he had considerable reserves. (especially since, in base, he also teleported Bijuda and biju).
